+# Jetbrains IDE Backend Plugin
+
+<!-- Plugin description -->
+Jetbrains IDE backend plugin to provide support for Gitpod.
+
+When installed in the headless Jetbrains IDE running in a Gitpod workspace, this plugin monitors user activity of the client IntelliJ and sends heartbeats accordingly. Avoiding the workspace timing out.
+<!-- Plugin description end -->
+
+**Warning**: Currently, given the challenge of mimicking user activity in a local Jetbrains IDE, there are no automated integration tests testing the functionality of this plugin. Please be particularly careful and manually test your changes.
+
+## Usage
+
+1. Produce the plugin by running `./gradlew buildPlugin`.
+2. Unzip `build/distributions/jetbrains-backend-plugin-1.0-SNAPSHOT.zip` to the `plugins/` folder of the headless Jetbrains IDE.
+3. Start the headless Jetbrains IDE.
