+<h1>Notebook storage options for Apache Zeppelin</h1>
+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p>Apache Zeppelin has a pluggable notebook storage mechanism controlled by <code>zeppelin.notebook.storage</code> configuration option with multiple implementations.
+There are few notebook storage systems available for a use out of the box:</p>
+
+<ul>
+<li>(default) use local file system and version it using local Git repository - <code>GitNotebookRepo</code></li>
+<li>all notes are saved in the notebook folder in your local File System - <code>VFSNotebookRepo</code></li>
+<li>all notes are saved in the notebook folder in hadoop compatible file system - <code>FileSystemNotebookRepo</code></li>
+<li>storage using Amazon S3 service - <code>S3NotebookRepo</code></li>
+<li>storage using Azure service - <code>AzureNotebookRepo</code></li>
+<li>storage using Google Cloud Storage - <code>GCSNotebookRepo</code></li>
+<li>storage using Aliyun OSS - <code>OSSNotebookRepo</code></li>
+<li>storage using MongoDB - <code>MongoNotebookRepo</code></li>
+<li>storage using GitHub - <code>GitHubNotebookRepo</code></li>
+</ul>
+
+<p>Multiple storage systems can be used at the same time by providing a comma-separated list of the class-names in the configuration.
+By default, only first two of them will be automatically kept in sync by Zeppelin.</p>
+
+<p></br></p>
+
+<h2>Notebook Storage in local Git repository <a name="Git"></a></h2>
+
+<p>To enable versioning for all your local notebooks though a standard Git repository - uncomment the next property in <code>zeppelin-site.xml</code> in order to use GitNotebookRepo class:</p>
+<div class="highlight"><pre><code class="xml language-xml" data-lang="xml"><span class="nt"><property></span>
+ <span class="nt"><name></span>zeppelin.notebook.storage<span class="nt"></name></span>
+ <span class="nt"><value></span>org.apache.zeppelin.notebook.repo.GitNotebookRepo<span class="nt"></value></span>
+ <span class="nt"><description></span>notebook persistence layer implementation<span class="nt"></description></span>
+<span class="nt"></property></span>
+</code></pre></div>
+<p></br></p>
+
+<h2>Notebook Storage in hadoop compatible file system repository <a name="Hdfs"></a></h2>
+
+<p>Notes may be stored in hadoop compatible file system such as hdfs, so that multiple Zeppelin instances can share the same notes. It supports all the versions of hadoop 2.x. If you use <code>FileSystemNotebookRepo</code>, then <code>zeppelin.notebook.dir</code> is the path on the hadoop compatible file system. And you need to specify <code>HADOOP_CONF_DIR</code> in <code>zeppelin-env.sh</code> so that zeppelin can find the right hadoop configuration files.
+If your hadoop cluster is kerberized, then you need to specify <code>zeppelin.server.kerberos.keytab</code> and <code>zeppelin.server.kerberos.principal</code></p>
+<div class="highlight"><pre><code class="xml language-xml" data-lang="xml"><span class="nt"><property></span>
+ <span class="nt"><name></span>zeppelin.notebook.storage<span class="nt"></name></span>
+ <span class="nt"><value></span>org.apache.zeppelin.notebook.repo.FileSystemNotebookRepo<span class="nt"></value></span>
+ <span class="nt"><description></span>hadoop compatible file system notebook persistence layer implementation<span class="nt"></description></span>
+<span class="nt"></property></span>
+</code></pre></div>
+<p></br></p>
+
+<h2>Notebook Storage in S3 <a name="S3"></a></h2>
+
+<p>Notebooks may be stored in S3, and optionally encrypted. The <a href="https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/DefaultAWSCredentialsProviderChain.html"><code>DefaultAWSCredentialsProviderChain</code></a> credentials provider is used for credentials and checks the following:</p>
+
+<ul>
+<li>The <code>AWS_ACCESS_KEY_ID</code> and <code>AWS_SECRET_ACCESS_KEY</code> environment variables</li>
+<li>The <code>aws.accessKeyId</code> and <code>aws.secretKey</code> Java System properties</li>
+<li>Credential profiles file at the default location (<code>~/.aws/credentials</code>) used by the AWS CLI</li>
+<li>Instance profile credentials delivered through the Amazon EC2 metadata service</li>
+</ul>
+
+<p></br>
+The following folder structure will be created in S3:</p>
+<div class="highlight"><pre><code class="text language-text" data-lang="text">s3://bucket_name/username/notebook-id/
+</code></pre></div>
+<p>Configure by setting environment variables in the file <strong>zeppelin-env.sh</strong>:</p>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash"><span class="nb">export </span><span class="nv">ZEPPELIN_NOTEBOOK_S3_BUCKET</span><span class="o">=</span>bucket_name
+<span class="nb">export </span><span class="nv">ZEPPELIN_NOTEBOOK_S3_USER</span><span class="o">=</span>username
+</code></pre></div>
+<p>Or using the file <strong>zeppelin-site.xml</strong> uncomment and complete the S3 settings:</p>
+<div class="highlight"><pre><code class="xml language-xml" data-lang="xml"><span class="nt"><property></span>
+ <span class="nt"><name></span>zeppelin.notebook.s3.bucket<span class="nt"></name></span>
+ <span class="nt"><value></span>bucket_name<span class="nt"></value></span>
+ <span class="nt"><description></span>bucket name for notebook storage<span class="nt"></description></span>
+<span class="nt"></property></span>
+<span class="nt"><property></span>
+ <span class="nt"><name></span>zeppelin.notebook.s3.user<span class="nt"></name></span>

+<h3>Google Cloud API Authentication</h3>
+
+<p>Note: On Google App Engine, Google Cloud Shell, and Google Compute Engine, these
+steps are not necessary if you are using the default built in service account.</p>
+
+<p>For more information, see <a href="https://cloud.google.com/docs/authentication/production">Application Default Credentials</a></p>
+
+<h4>Using gcloud auth application-default login</h4>
+
+<p>See the <a href="https://cloud.google.com/sdk/gcloud/reference/auth/application-default/login">gcloud docs</a></p>
+
+<p>As the user running the zeppelin daemon, run:</p>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash">gcloud auth application-default login
+</code></pre></div>
+<p>You can also use <code>--scopes</code> to restrict access to specific Google APIs, such as
+Cloud Storage and BigQuery.</p>
+
+<h4>Using service account key files</h4>
+
+<p>Alternatively, to use a <a href="https://cloud.google.com/compute/docs/access/service-accounts">service account</a>
+for authentication with GCS, you will need a JSON service account key file.</p>
+
+<ol>
+<li>Navigate to the <a href="https://console.cloud.google.com/iam-admin/serviceaccounts/project">service accounts page</a></li>
+<li>Click <code>CREATE SERVICE ACCOUNT</code></li>
+<li>Select at least <code>Storage -> Storage Object Admin</code>. Note that this is
+<strong>different</strong> than <code>Storage Admin</code>.</li>
+<li>If you are also using the BigQuery Interpreter, add the appropriate
+permissions (e.g. <code>Bigquery -> Bigquery Data Viewer and BigQuery User</code>)</li>
+<li>Name your service account, and select "Furnish a new private key" to download
+a <code>.json</code> file. Click "Create".</li>
+<li><p>Move the downloaded file to a location of your choice (e.g.
+<code>/path/to/my/key.json</code>), and give it appropriate permissions. Ensure at
+least the user running the zeppelin daemon can read it.</p>
+
+<p>If you wish to set this as your default credential file to access Google Services,
+point <code>GOOGLE_APPLICATION_CREDENTIALS</code> at your new key file in <strong>zeppelin-env.sh</strong>. For example:</p></li>
+</ol>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash"><span class="nb">export </span><span class="nv">GOOGLE_APPLICATION_CREDENTIALS</span><span class="o">=</span>/path/to/my/key.json

+<p>By setting <code>ZEPPELIN_NOTEBOOK_MONGO_AUTOIMPORT</code> as <code>true</code> (default <code>false</code>), you can import your local notes automatically when Zeppelin daemon starts up. This feature is for easy migration from local file system storage to MongoDB storage. A note with ID already existing in the collection will not be imported.</p>
+
+<h2>Notebook Storage in GitHub</h2>
+
+<p>To enable GitHub tracking, uncomment the following properties in <code>zeppelin-site.xml</code></p>
