+# Extensions
+
+Extensions are Views, Backends or other pieces of code that build on Recline but which do not ship as part of the core distribution. Here we have:
+
+* Instructions on creating an extension
+* A list of existing extensions
+ * **If you have created an extension please add it to the list below**
+
+## Creating an Extension
+
+At its minimum its just a single JS file. However, we suggest a bit more structure:
+
+* Put the extension in its own repo named e.g. recline.view.{viewname} or recline.backend.{backendname}
+* Including (essential):
+  * README.md
+  * the extension code itself name view.{name}.js or backend.{name}.js (or recline.view.{name}.js etc)
+* Optional
+  * [optional but recommended] a test for the extension
+  * [optional] one or more demo html files showing your extension in action
+
+You may want to include recline as a submodule for testing purposes if you need some of its code
+        
+    git submodule add git://github.com/okfn/recline.git
+
+Or you can just pull the latest recline.js directly from: http://okfnlabs.org/recline/dist/recline.js
