+
+  `pluginsFunc` is a function that should return an attribute set of plugins
+  to be included in the WAR.
+
+  The plugins are provided by `pkgs.jenkinsUpdateCenter.plugins`.
+  Dependencies between those plugins are automatically resolved within the
+  same jenkinsUpdateCenter.
+
+  Example:
+
+    pkgs.jenkinsWithPlugins
+      (plugins: {
+        inherit (plugins) BlameSubversion ... ;
+        inherit (pkgs) my-plugin;
+      })
+
+  Each attribute of `plugins` is a derivation and you can return in
+  the set any other plugins that are not available in Jenkins registry
+  (https://updates.jenkins-ci.org/) or replacing plugins in the registry.
+
+  Non-optional dependencies, if any, are automatically added. Optional
+  dependencies are ignored, you have to add them explicitly.
