 =========
 
 Python simulator of a puny universe. (How many words can i stick into one?)
+
+Installation
+------------
+
+To install, simply clone this repository, or download a copy [here]
+(https://github.com/xiaomao5/punyverse/archive/master.zip).
+
+After that, download the [launcher](https://github.com/xiaomao5/punyverse/releases/download/launcher0.2/launcher.exe),
+put it into the repository directory and let it unpack in your repository (or copy).
+
+You may start playing any time by running `punyverse.exe`, or `punyverse_debug.exe` if you desire a console.
+
+### A Note on Textures
+
+If your graphics card doesn't support the massive texture sizes this module comes with, you can shrink them.
+
+You can run `small_images.exe` (or `small_images.py`, which requires either `PIL` or `pgmagick`) to generate
+smaller versions of shipped textures.
+
+###Advanced Install
+
+You need a C compiler to compile `_model.c` and `_glgeom.c`, both requiring OpenGL headers and libraries.
+
+You will also need to install `pyglet`.
+
+You can now run the `punyverse` module using `python -mpunyverse`.
+
+See above if you run into texture issues.
