+### Git Submodules
+
+This project uses Git Submodules. This means that you should clone it recursively if you're planning on working on it:
+
+```bash
+$ git clone --recurse-submodules https://github.com/Level/leveldown.git
+```
+
+Alternatively, you can initalize submodules inside the cloned folder:
+
+```bash
+$ git submodule update --init --recursive
+```
+
+### Windows
+
+A large portion of the Windows support comes from code by [Krzysztof Kowalczyk](http://blog.kowalczyk.info/) [@kjk](https://twitter.com/kjk), see his Windows LevelDB port [here](http://code.google.com/r/kkowalczyk-leveldb/). If you're using LevelUP on Windows, you should give him your thanks!
