 Bug reports, issues, feature requests, and other contributions are welcome. If you find
 a demonstrable problem that is caused by the REANA code, please:
 
-1. Search for `already reported problems

 2. Check if the issue has been fixed or is still reproducible on the
    latest `master` branch.
 3. Create an issue, ideally with **a test case**.
 
 If you create a pull request fixing a bug or implementing a feature, you can run
 the tests to ensure that everything is operating correctly:
 
-.. code-block:: console
-
-    $ ./run-tests.sh
+```console
+$ ./run-tests.sh
+```
 
 Each pull request should preserve or increase code coverage.

+## About
+
+[REANA](http://www.reana.io) is a reusable and reproducible research data analysis
+platform. It helps researchers to structure their input data, analysis code,
+containerised environments and computational workflows so that the analysis can be
+instantiated and run on remote compute clouds.
+
+REANA was born to target the use case of particle physics analyses, but is applicable to
+any scientific discipline. The system paves the way towards reusing and reinterpreting
+preserved data analyses even several years after the original publication.
+
+## Features
+
+- structure research data analysis in reusable manner
+- instantiate computational workflows on remote clouds
+- rerun analyses with modified input data, parameters or code
+- support for several compute clouds (Kubernetes/OpenStack)
+- support for several workflow specifications (CWL, Serial, Yadage, Snakemake)
+- support for several shared storage systems (Ceph)
+- support for several container technologies (Docker)
+
+## Getting started
+
+You can
+[install REANA locally](https://docs.reana.io/administration/deployment/deploying-locally/),
+[deploy it at scale on premises](https://docs.reana.io/administration/deployment/deploying-at-scale/)
+(in about 10 minutes) or use <https://reana.cern.ch>. Once the system is ready, you can
+follow the guide to run
+[your first example](https://docs.reana.io/getting-started/first-example/). For more in
+depth information visit the [official REANA documentation](https://docs.reana.io/).
