+#Etcdlib
+etcd is a distributed, consistent key-value store for shared configuration and service discovery, part of the CoreOS project.
+
+This repository provides a library for etcd for C applications.
+
+Etcdlib can be used as part of Celix but is also useable stand-alone.
+
+##Preparing
+The following packages (libraries + headers) should be installed on your system:
+
+*	Development Environment
+	*	build-essentials (gcc/g++ or clang/clang++)
+	*	cmake (3.2 or higher)
+
+* 	Etcdlib Dependencies
+	*	curl
+	*	jansson
+
+##Download the Apache Celix sources
+To get started you first have to download the Apache Celix sources. This can be done by cloning the Apache Celix git repository:
+
+```bash
+#Create a new workspace to work in, e.g:
+mkdir -p ${HOME}/workspace
+export WS=${HOME}/workspace
+cd ${WS}
+
+#clone the repro
+git clone --single-branch --branch develop https://github.com/apache/celix.git
+```
+
+##Building
+Etcdlib uses [CMake](https://cmake.org) as build system. CMake can generate (among others) makefiles or ninja build files. Using ninja build files will result in a faster build.
+
+###Building using CMake and makefiles:
+```bash
+cd ${WS}/celix/etcdlib
+mkdir build
+cd build
+cmake .. 
+make 
+```
+
+###Building using CMake and Ninja
+```bash
+cd ${WS}/celix/etcdlib
+mkdir build
+cd build
+cmake -G Ninja ..
+ninja
+```
+
+##Editing Build options
+With use of CMake, Etcdlib makes it possible to edit build options. This enabled users, among other options, to configure a install location.
+To edit the options use ccmake or cmake-gui. For cmake-gui an additional package install can be necessary (Fedora: `dnf install cmake-gui`). 
+
+```bash
+cd ${WS}/celix/etcdlib/build
+ccmake .
+#Edit the CMAKE_INSTALL_PREFIX config to set the install location
+```
+
+For this guide we assume the CMAKE_INSTALL_PREFIX is `/usr/local`.
+
+##Installing Etcdlib
+
+```bash
+cd ${WS}/celix/etcdlib/build
+make
+sudo make install
+```
