+# Plugins
+
+!Plugin support for panels is only available in nightly!
+
+Adding support for all datasources and suggested panels would bloat grafana and make it impossible to maintain. That's why we implemented a plugin system that makes it possible for anyone to develop support for a datasource or custom panel without adding it to Grafana itself.
+
+## Installing plugins
+
+Installing a plugin is very simple. Just download it and place it in the Grafana plugins folder and restart grafana.
+
+The default plugin folder is configurable under paths.plugins
+
+It's also possible to add one specific plugin by linking to its folder.
+
+```
+[plugin.mirror]
+path = /home/evil-queen/datasource-plugin-mirror
+```
+
+## Plugin implementation ##
+
+Each plugin is defined in plugin.json file in the plugin folder.
+
+Instead of massive documentation about how it works we created a reference implementation of a plugin.
+You can find each reference implementation further down on this page.
+
+## Datasource plugins
+
+Datasource have three responsibilities.
+
+ * UI for configuring its settings
+ * Datasource object that can send queries, metricqueries and healthcheck the datasource
+ * Query editor within panels
+
+https://github.com/grafana/datasource-plugin-genericdatasource
+
+## Panel plugins
+
+Panel plugins are responsible for
+
+ * UI for Panel options.
+ * Creating a directive that can render something based on datasource data.
+
+We currently dont have a reference implementation for panel plugins but you can checkout https://github.com/grafana/panel-plugin-piechart
