+DMDirc plugins
+================================================================================
+
+This repository contains plugins for [DMDirc](https://www.dmdirc.com/), a Java
+IRC client.
+
+Development information
+--------------------------------------------------------------------------------
+
+### Gradle configurations
+
+We have two custom configurations for use when defining plugin dependencies:
+
+The **bundle** configuration allows dependencies to be bundled together into
+the plugin's jar file. This should be used for dependencies required at runtime
+that are not included in the main DMDirc client, or accessed via other plugins.
+Most of a plugin's dependencies should end up in the bundle configuration.
+
+The **provided** configuration works like the Maven 'provided' scope. It
+defines dependencies required to compile and run the plugin that will be
+provided to it somehow externally. Anything in the provided configuration
+(including transitive dependencies) will *not* be bundled into the plugin jar.
+The provided configuration is used for the main DMDirc client, and should be
+used for any intra-plugin dependencies.
