@@ -19,3 +19,34 @@ In order to use the Sluift Lua module, make sure it is copied to a location in t
Lua search path (`LUA_PATH`, or the built-in path). On Linux and Mac OS X, this is
typically `<LUA_INSTALLPREFIX>/lib/lua/<LUA_VERSION>/`. If `require 'sluift'` fails,
the error message will give an indication what this path is.

+
+## Examples
+
+Example scripts can be found in `Examples/`, and in the Swift tree under
+`Swiften/QA/ScriptedTests`.
+
+## Extending
+
+### Adding support for payloads
+
+To add support for a specific Swiften payload, create a new `LuaElementConvertor`
+in `ElementConvertors/` by inheriting from `GenericLuaElementConvertor`, and register
+it it `LuaElementConvertors.cpp`. The name of the convertor passed in the constructor
+of `GenericLuaElementConvertor` should correspond to the snake case version of the
+Swiften element it converts. For examples, see the existing convertors in
+`ElementConvertors/`.
+
+When the convertor is registered, you can use it in message bodies, or in get/set
+queries. For example, for the `command` convertor:
+
+ client:set{to = 'alice@wonderland.lit', query = {_type = 'command',
+ type = 'execute', node = 'uptime'}}
+
+Optionally, you can add a convenience `set_<type>` shortcut on the client object by
+adding it to the list of `get_set_shortcuts` in `boot.lua`. With such a shortcut, the
+command above can be rewritten as:
+
+ client:set_command{to = 'alice@wonderland.lit', command = {
+ type = 'execute', node = 'uptime'}}
