+Download Commands
+-----------------
+
+Gerrit offers commands for downloading changes using different
+download schemes (e.g. for downloading via different network
+protocols). Plugins can contribute download schemes and download
+commands by implementing
+`com.google.gerrit.extensions.config.DownloadScheme` and
+`com.google.gerrit.extensions.config.DownloadCommand`.
+
+The download schemes and download commands which are used most often
+are provided by the Gerrit core plugin `download-commands`.
