+## About
+
+REANA-Workflow-Engine-Serial is a component of the [REANA](http://www.reana.io/) reusable
+and reproducible research data analysis platform. It takes care of instantiating,
+executing and managing simple sequential computational workflows.
+
+## Features
+
+- Run sequential workflows consisting of Bash commands.
+- Cache workflow steps by default to shorten computation time.
+
+## Usage
+
+The detailed information on how to install and use REANA can be found in
+[docs.reana.io](https://docs.reana.io).
