+ the conditions stated in this License.
+
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
+ any Contribution intentionally submitted for inclusion in the Work
+ by You to the Licensor shall be under the terms and conditions of
+ this License, without any additional terms or conditions.
+ Notwithstanding the above, nothing herein shall supersede or modify
+ the terms of any separate license agreement you may have executed
+ with Licensor regarding such Contributions.
+
+ 6. Trademarks. This License does not grant permission to use the trade
+ names, trademarks, service marks, or product names of the Licensor,
+ except as required for reasonable and customary use in describing the
+ origin of the Work and reproducing the content of the NOTICE file.
+
+ 7. Disclaimer of Warranty. Unless required by applicable law or
+ agreed to in writing, Licensor provides the Work (and each
+ Contributor provides its Contributions) on an "AS IS" BASIS,

+ unless required by applicable law (such as deliberate and grossly
+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,
+ work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.
+
+ 9. Accepting Warranty or Additional Liability. While redistributing
+ the Work or Derivative Works thereof, You may choose to offer,
+ and charge a fee for, acceptance of support, warranty, indemnity,
+ or other liability obligations and/or rights consistent with this
+ License. However, in accepting such obligations, You may act only
+ on Your own behalf and on Your sole responsibility, not on behalf
+ of any other Contributor, and only if You agree to indemnify,
+ defend, and hold each Contributor harmless for any liability
+ incurred by, or claims asserted against, such Contributor by reason
+ of your accepting any such warranty or additional liability.

+
+The EPL/LGPL dual-license serves several purposes. The LGPL license ensures continuity in terms of licensing of the logback project. Prior to version 0.9.18, logback was licensed (exclusively) under the LGPL v2.1. Moreover, since the EPL is deemed incompatible by the Free Software Foundation, the LGPL will allow various licensees, in particular software distributors who may be already bound by the terms of the GPL or the LGPL, to distribute our software.
+
+On the other hand, the EPL license will placate organizations which refuse certain restrictions imposed by the LGPL.
+
+Please note that logback-classic is intended to be used behind the SLF4J API, which is licensed under the MIT license.
+
+If you wish to make a significant contribution to the logback project, you are invited to file a Contributor License Agreement. The purpose of this agreement is to formalize the terms of your contribution and to protect the project in case of litigation.
+
+Upon request, we may exempt open-source projects from LGPL and EPL's reciprocity clauses so that the said projects can develop logback extensions under the license of their choice. Exemptions are granted on a case by case basis.

+ The GNU General Public License (GPL) Version 2, June 1991
+
+Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+51 Franklin Street, Fifth Floor
+Boston, MA 02110-1335
+USA
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public License is
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users. This General Public
+License applies to most of the Free Software Foundation's software and
+to any other program whose authors commit to using it. (Some other Free
+Software Foundation software is covered by the GNU Library General
+Public License instead.) You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price.
+Our General Public Licenses are designed to make sure that you have the
+freedom to distribute copies of free software (and charge for this
+service if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs; and that you know you can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone
+to deny you these rights or to ask you to surrender the rights. These
+restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis
+or for a fee, you must give the recipients all the rights that you have.
+You must make sure that they, too, receive or can get the source code.
+And you must show them these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+Finally, any free program is threatened constantly by software patents.
+We wish to avoid the danger that redistributors of a free program will
+individually obtain patent licenses, in effect making the program
+proprietary. To prevent this, we have made it clear that any patent must
+be licensed for everyone's free use or not licensed at all.
+
+The precise terms and conditions for copying, distribution and
+modification follow.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License applies to any program or other work which contains a
+notice placed by the copyright holder saying it may be distributed under
+the terms of this General Public License. The "Program", below, refers
+to any such program or work, and a "work based on the Program" means
+either the Program or any derivative work under copyright law: that is
+to say, a work containing the Program or a portion of it, either
+verbatim or with modifications and/or translated into another language.
+(Hereinafter, translation is included without limitation in the term
+"modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of running
+the Program is not restricted, and the output from the Program is
+covered only if its contents constitute a work based on the Program
+(independent of having been made by running the Program). Whether that
+is true depends on what the Program does.
+
+1. You may copy and distribute verbatim copies of the Program's source
+code as you receive it, in any medium, provided that you conspicuously
+and appropriately publish on each copy an appropriate copyright notice
+and disclaimer of warranty; keep intact all the notices that refer to
+this License and to the absence of any warranty; and give any other
+recipients of the Program a copy of this License along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Program or any portion of
+it, thus forming a work based on the Program, and copy and distribute
+such modifications or work under the terms of Section 1 above, provided
+that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any part
+ thereof, to be licensed as a whole at no charge to all third parties
+ under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a notice
+ that there is no warranty (or else, saying that you provide a
+ warranty) and that users may redistribute the program under these
+ conditions, and telling the user how to view a copy of this License.
+ (Exception: if the Program itself is interactive but does not
+ normally print such an announcement, your work based on the Program
+ is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program, and
+can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based on
+the Program, the distribution of the whole must be on the terms of this
+License, whose permissions for other licensees extend to the entire
+whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of a
+storage or distribution medium does not bring the other work under the
+scope of this License.
+
+3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections 1
+ and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your cost
+ of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer to
+ distribute corresponding source code. (This alternative is allowed
+ only for noncommercial distribution and only if you received the
+ program in object code or executable form with such an offer, in
+ accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source code
+means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to control
+compilation and installation of the executable. However, as a special
+exception, the source code distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies the
+executable.
+
+If distribution of executable or object code is made by offering access
+to copy from a designated place, then offering equivalent access to copy
+the source code from the same place counts as distribution of the source
+code, even though third parties are not compelled to copy the source
+along with the object code.
+
+4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt otherwise
+to copy, modify, sublicense or distribute the Program is void, and will
+automatically terminate your rights under this License. However, parties
+who have received copies, or rights, from you under this License will
+not have their licenses terminated so long as such parties remain in
+full compliance.
+
+5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and all
+its terms and conditions for copying, distributing or modifying the
+Program or works based on it.
+
+6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further restrictions
+on the recipients' exercise of the rights granted herein. You are not
+responsible for enforcing compliance by third parties to this License.
+
+7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot distribute
+so as to satisfy simultaneously your obligations under this License and
+any other pertinent obligations, then as a consequence you may not
+distribute the Program at all. For example, if a patent license would
+not permit royalty-free redistribution of the Program by all those who
+receive copies directly or indirectly through you, then the only way you
+could satisfy both it and this License would be to refrain entirely from
+distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is implemented
+by public license practices. Many people have made generous
+contributions to the wide range of software distributed through that
+system in reliance on consistent application of that system; it is up to
+the author/donor to decide if he or she is willing to distribute
+software through any other system and a licensee cannot impose that choice.
+
+This section is intended to make thoroughly clear what is believed to be
+a consequence of the rest of this License.
+
+8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License may
+add an explicit geographical distribution limitation excluding those
+countries, so that distribution is permitted only in or among countries
+not thus excluded. In such case, this License incorporates the
+limitation as if written in the body of this License.
+
+9. The Free Software Foundation may publish revised and/or new
+versions of the General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Program does not specify a version
+number of this License, you may choose any version ever published by the
+Free Software Foundation.
+
+10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the
+author to ask for permission. For software which is copyrighted by the
+Free Software Foundation, write to the Free Software Foundation; we
+sometimes make exceptions for this. Our decision will be guided by the
+two goals of preserving the free status of all derivatives of our free
+software and of promoting the sharing and reuse of software generally.
+
+NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND,
+EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH
+YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
+(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR
+OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to
+attach them to the start of each source file to most effectively convey
+the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ One line to give the program's name and a brief idea of what it does.
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful, but
+ WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1335 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type
+ `show w'. This is free software, and you are welcome to redistribute
+ it under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the
+appropriate parts of the General Public License. Of course, the commands
+you use may be called something other than `show w' and `show c'; they
+could even be mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the

+This General Public License does not permit incorporating your program

+Certain source files distributed by Oracle America, Inc. and/or its

+exception to the GPLv2, based on the GNU Project exception for its
+Classpath libraries, known as the GNU Classpath Exception, but only
+where Oracle has expressly included in the particular source file's
+header the words "Oracle designates this particular file as subject to
+the "Classpath" exception as provided by Oracle in the LICENSE file
+that accompanied this code."
+
+You should also note that Oracle includes multiple, independent
+programs in this software package. Some of those programs are provided
+under licenses deemed incompatible with the GPLv2 by the Free Software
+Foundation and others. For example, the package includes programs
+licensed under the Apache License, Version 2.0. Such programs are
+licensed to you under their original licenses.
+
+Oracle facilitates your further distribution of this package by adding
+the Classpath Exception to the necessary parts of its GPLv2 code, which
+permits you to use that code in combination with other independent
+modules not licensed under the GPLv2. However, note that this would
+not permit you to commingle code under an incompatible license with
+Oracle's GPLv2 licensed code by, for example, cutting and pasting such
+code into a file also containing Oracle's GPLv2 licensed code and then
+distributing the result. Additionally, if you were to remove the
+Classpath Exception from any of the files to which it applies and
+distribute the result, you would likely be required to license some or
+all of the other code in that distribution under the GPLv2 as well, and
+since the GPLv2 is incompatible with the license terms of some items
+included in the distribution by Oracle, removing the Classpath
+Exception could therefore effectively compromise your ability to
+further distribute the package.
+
+Proceed with caution and we recommend that you obtain the advice of a
+lawyer skilled in open source matters before removing the Classpath
+Exception or making modifications to this package which may
+subsequently be redistributed and/or involve the use of third party
+software.

+# Overview
+
+IoTDB (Internet of Things Database) is an integrated data management engine designed for time series data, which can provide users specific services for data collection, storage and analysis. Due to its light weight structure, high performance and usable features together with its intense integration with Hadoop and Spark ecology, IoTDB meets the requirements of massive dataset storage, high-speed data input and complex data analysis in the IoT industrial field.
+
+# Main Features
+
+IoTDB's features are as following:
+
+1. Flexible deployment. IoTDB provides users one-click installation tool on the cloud, once-decompressed-used terminal tool and the bridge tool between cloud platform and terminal tool (Data Synchronization Tool).
+2. Low cost on hardware. IoTDB can reach a high compression ratio of disk storage
+3. Efficient directory structure. IoTDB supports efficient organization for complex time series data structure from intelligent networking devices, organization for time series data from devices of the same type, fuzzy searching strategy for massive and complex directory of time series data.
+4. High-throughput read and write. IoTDB supports millions of low-power devices' strong connection data access, high-speed data read and write for intelligent networking devices and mixed devices mentioned above.
+5. Rich query semantics. IoTDB supports time alignment for time series data across devices and sensors, computation in time series field (frequency domain transformation) and rich aggregation function support in time dimension.
+6. Easy to get start. IoTDB supports SQL-Like language, JDBC standard API and import/export tools which is easy to use.
+7. Intense integration with Open Source Ecosystem. IoTDB supports Hadoop, Spark, etc. analysis ecosystems and Grafana visualization tool.
+
+For the latest information about IoTDB, please visit our [IoTDB official website](https://iotdb.apache.org/).
+
+# Prerequisites
+
+IoTDB requires Java (>= 1.8), To use IoTDB, JRE should be installed.
+
+If you want to compile and install IoTDB from source code, JDK and Maven (>= 3.1) are required.
+While Maven is not mandatory to be installed standalone, you can use the provided Maven wrapper, `./mvnw.sh` on Linux/OS X or `.\mvnw.cmd` on Windows, to facilitate development.
+
+If you want to use Hadoop or Spark to analyze IoTDB data file (called as TsFile), you need to compile the hadoop and spark modules.
+
+# Quick Start
+
+This short guide will walk you through the basic process of using IoTDB. For a more-complete guide, please visit our website's [User Guide](https://iotdb.apache.org/#/Documents/latest/sec1).
+
+## Installation from source code
+
+Use git to get IoTDB source code:
+
+```
+> git clone https://github.com/apache/incubator-iotdb.git
+```
+
+Or use the following command if you have configured SSH key on GitHub:
+
+```
+> git clone git@github.com:apache/incubator-iotdb.git
+```
+
+Now suppose your directory is like this:
+
+```
+> pwd
+/workspace/incubator-iotdb
+
+> ls -l
+incubator-iotdb/ <-- root path
+|
++- iotdb/
+|
++- jdbc/
+|
++- tsfile/
+|
+...
+|
++- pom.xml
+```
+
+Let $IOTDB_HOME = /workspace/incubator-iotdb/iotdb/iotdb/
+
+Let $IOTDB_CLI_HOME = /workspace/incubator-iotdb/iotdb-cli/cli
+
+If you are not the first time that building IoTDB, remember deleting the following files:
+
+```
+> rm -rf $IOTDB_HOME/data/
+> rm -rf $IOTDB_HOME/lib/
+```
+
+Then under the root path of incubator-iotdb, you can build IoTDB using Maven:
+
+```
+> pwd
+/workspace/incubator-iotdb
+
+> mvn clean package -pl iotdb -am -Dmaven.test.skip=true
+```
+
+If successful, you will see the the following text in the terminal:
+
+```
+[INFO] ------------------------------------------------------------------------
+[INFO] Reactor Summary:
+[INFO]
+[INFO] IoTDB Root ......................................... SUCCESS [ 7.020 s]
+[INFO] TsFile ............................................. SUCCESS [ 10.486 s]
+[INFO] Service-rpc ........................................ SUCCESS [ 3.717 s]
+[INFO] IoTDB Jdbc ......................................... SUCCESS [ 3.076 s]
+[INFO] IoTDB .............................................. SUCCESS [ 8.258 s]
+[INFO] ------------------------------------------------------------------------
+[INFO] BUILD SUCCESS
+[INFO] ------------------------------------------------------------------------
+```
+Otherwise, you may need to check the error statements and fix the problems.
+
+After build, the IoTDB project will be at the folder "iotdb/iotdb". The folder will include the following contents:
+
+```
+iotdb/iotdb/ <-- root path
+|
++- bin/ <-- script files
+|
++- conf/ <-- configuration files
+|
++- lib/ <-- project dependencies
+```
+
+<!-- > NOTE: We also provide already built JARs and project at [http://tsfile.org/download](http://tsfile.org/download) instead of build the jar package yourself. -->
+
+## Configure
+
+Before starting to use IoTDB, you need to config the configuration files first. For your convenience, we have already set the default config in the files.
+
+In total, we provide users three kinds of configurations module: environment config module (iotdb-env.bat, iotdb-env.sh), system config module (tsfile-format.properties, iotdb-engine.properties) and log config module (logback.xml). All of these kinds of configuration files are put in iotdb/config folder.
+
+For more, you are advised to check our documentation [Chapter4: Deployment and Management](https://iotdb.apache.org/#/Documents/latest/sec4) in detail.
+
+## Start
+
+### Start Server
+
+After that we start the server. Running the startup script:
+
+```
+# Unix/OS X
+> $IOTDB_HOME/bin/start-server.sh
+
+# Windows
+> $IOTDB_HOME\bin\start-server.bat
+```
+
+### Stop Server
+
+The server can be stopped with ctrl-C or the following script:
+
+```
+# Unix/OS X
+> $IOTDB_HOME/bin/stop-server.sh
+
+# Windows
+> $IOTDB_HOME\bin\stop-server.bat
+```
+
+### Start Client
+
+Now let's trying to read and write some data from IoTDB using our Client. To start the client, you need to explicit the server's IP and PORT as well as the USER_NAME and PASSWORD.
+
+```
+# You can first build cli project
+> pwd
+/workspace/incubator-iotdb
+
+> mvn clean package -pl iotdb-cli -am -Dmaven.test.skip=true
+
+# Unix/OS X
+> $IOTDB_CLI_HOME/bin/start-client.sh -h <IP> -p <PORT> -u <USER_NAME>
+
+# Windows
+> $IOTDB_CLI_HOME\bin\start-client.bat -h <IP> -p <PORT> -u <USER_NAME>
+```
+
+> NOTE: In the system, we set a default user in IoTDB named 'root'. The default password for 'root' is 'root'. You can use this default user if you are making the first try or you didn't create users by yourself.
+
+The command line client is interactive so if everything is ready you should see the welcome logo and statements:
+
+```
+ _____ _________ ______ ______
+|_ _| | _ _ ||_ _ `.|_ _ \
+ | | .--.|_/ | | \_| | | `. \ | |_) |
+ | | / .'`\ \ | | | | | | | __'.
+ _| |_| \__. | _| |_ _| |_.' /_| |__) |
+|_____|'.__.' |_____| |______.'|_______/ version x.x.x
+
+
+IoTDB> login successfully
+IoTDB>
+```
+### Have a try
+Now, you can use IoTDB SQL to operate IoTDB, and when you've had enough fun, you can input 'quit' or 'exit' command to leave the client.
+
+But lets try something slightly more interesting:
+
+```
+IoTDB> SET STORAGE GROUP TO root.vehicle
+execute successfully.
+IoTDB> CREATE TIMESERIES root.vehicle.d0.s0 WITH DATATYPE=INT32, ENCODING=RLE
+execute successfully.
+```
+Till now, we have already create a table called root.vehicle and add a column called d0.s0 in the table. Let's take a look at what we have done by 'SHOW TIMESERIES' command.
+
+```
+IoTDB> SHOW TIMESERIES
+=== Timeseries Tree ===
+
+root:{
+ vehicle:{
+ d0:{
+ s0:{
+ DataType: INT32,
+ Encoding: RLE,
+ Compressor: UNCOMPRESSED,
+ args: {},
+ StorageGroup: root.vehicle
+ }
+ }
+ }
+}
+```
+Insert time series data is the basic operation of IoTDB, you can use 'INSERT' command to finish this:
+
+```
+IoTDB> insert into root.vehicle.d0(timestamp,s0) values(1,101);
+execute successfully.
+```
+The data we've just inserted displays like this:
+
+```
+IoTDB> SELECT d0.s0 FROM root.vehicle
++-----------------------+------------------+
+| Time|root.vehicle.d0.s0|
++-----------------------+------------------+
+|1970-01-01T08:00:00.001| 101|
++-----------------------+------------------+
+record number = 1
+execute successfully.
+```
+
+If your session looks similar to what's above, congrats, your IoTDB is operational!
+
+For more on what commands are supported by IoTDB SQL, see our documentation [Chapter 5: IoTDB SQL Documentation](https://iotdb.apache.org/#/Documents/latest/sec5).

+### Query Status of Nodes in Cluster (status)
+
+IoTDB Cluster contains multiple nodes. For any node, there is a possibility that the service cannot be provided normally due to problems of network and hardware. With this command, users are able to know the current status of all nodes in the cluster.
+
+#### Input
+
+The command to query status of nodes is `status`, no additional parameters are needed.
+
+#### Output
+
+The output is multiple string lines, each line represents a key-value pair, where the key is node IP and the value is status of this node (`on` represents normal and `off` represents abnormal. The format of each line is `key -> value`.
+
+#### Example
+
+Assume that the IoTDB Cluster is running on 3 nodes: 192.168.130.14, 192.168.130.16 and 192.168.130.18, and number of replicas is 2.
+
+The Linux and MacOS system startup commands are as follows:
+```
+ Shell > ./bin/nodetool.sh -h 192.168.130.14 status
+```
+
+The Windows system startup commands are as follows:
+```
+ Shell > \bin\nodetool.bat -h 192.168.130.14 status
+```
+
+After using the command, the successful output will be as follows:
+
+```
+192.168.130.14 -> on
+192.168.130.16 -> on
+192.168.130.18 -> off
+```
- The above output indicates that node 192.168.130.14 and node 192.168.130.16 are in normal state, and node 192.168.130.18 cannot provide services.
