 # Eclipse zenoh C Client API
 
-## Building 
+[Eclipse zenoh](http://zenoh.io) is an extremely efficient and fault-tolerant [Named Data Networking](http://named-data.net) (NDN) protocol 
+that is able to scale down to extremely constrainded devices and networks. 
+
+The C API is for pure clients, in other terms does not support peer-to-peer communication, can be easily tested against a zenoh router running in a Docker container (see https://github.com/eclipse-zenoh/zenoh#how-to-test-it). 
+
+-------------------------------
+## How to install it
+
+The Eclipse zenoh-c library is available as **Debian** or **RPM** packages in the [Eclipse zenoh download area](https://download.eclipse.org/zenoh/zenoh-c/).
+Those packages are built using manylinux2010 x86-32 and x86-64 to be compatible with most of the Linux platforms.
+There are 2 kind of packages:
+
+ - **libzenohc**: only contains the library file (.so)
+ - **libzenohc-dev**: contains the zenoh-c header files for development. Depends on *libzenohc* package
+
+For other platforms, you will need to clone and build the sources.
+
+WARNING: Note that zenoh-c has not been ported on Windows yet!
+
+-------------------------------
+## How to build it 
 To build the **zenoh-c** client API you need to ensure that [cmake](https://cmake.org) is available on your platform -- if not please install it.

 ## Running the Examples
