-Plugin for Rainmeter enabling Python scripting
+Plugin for Rainmeter enabling Python 3 scripting
+
+Installation
+------------
+
+For this plugin to function, you need to install the Python 3.3 distribution matching your Rainmeter's architecture.
+The corresponding 'python33.dll' needs to be in your DLL search path; all standard installers of Python 3.3 automatically put the DLL into your System32 directory, so this should normally be the case.
+
+Example
+-------
+```ini
+[Measure]
+Measure=Plugin
+Plugin=Plugins\Python.dll
+PythonHome=c:\Python33
+ScriptPath=default.py
+ClassName=Measure
+UpdateRate=1
+```
+
+```python
+class Measure:
+  def Reload(self, rm, maxValue):
+    rm.RmLog(rm.LOG_NOTICE, "Reload called")
+
+  def Update(self):
+    return 1.0
+
+  def GetString(self):
+    return 'Test'
+
+  def ExecuteBang(self, args):
+    pass
+
+  def Finalize(self):
+    pass
