 ## Installation & Usage
 
-_Coming soon._
+Just grab one of the releases [over here][releases] and unzip it. Copy the entire `3DS.py`
+folder to the `3ds` directory of your SD card and navigate into it. You should
+see a `3DS.py.3dsx` application.
+
+The same directory also contains the entire Python standard library and a `main.py` file.
+To run your own projects, copy all source files into the `3DS.py` directory and "start"
+your application from within the `main.py` file as this is the entry point to any Python
+homebrew.
