-# E-CORD Developer Guid
+# E-CORD Developer Guide
+
+This page describes general guidelines for developers who want to download and work on the E-CORD source code, or need to mock special development environments.
+
+## Download the E-CORD source code
+E-CORD is part of the default CORD code base. To know how you can download the CORD source code, go [here](https://guide.opencord.org/install.html).
+Each E-CORD service lives in a specific repository. A list of E-CORD services and links to their repositories is available in the [main page of this guide](https://guide.opencord.org/profiles/ecord/).
+
+NOTE: The E-CORD source code is available from the 4.1 release (branch) of CORD.
+
+## Developer Environments
 
 As for other CORD profiles, E-CORD can also be deployed in environments other than physical PODs. This creates a more convenient environment for developers, using less resources and providing a faster development life-cycle.
