+# dr_libs.jai
+
+Jai bindings for [dr_libs](https://github.com/mackron/dr_libs)
+
+## Initial setup
+
+If you want to build the lib then you'll need the source code. You can do this with: `git submodule update --init --recursive`.
+In the future if you need to pull in the source submodule again (e.g. the folder got deleted), then run: `git submodule update --recursive`
+
+## Usage
+
+Simply import the module. If you're using a static library version then you're set. If you generated a DLL (and new bindings to load it) then you need to copy the DLL from the windows/ folder to the working directory of your exe.
+
+## TODO
+
+* Add support for other platforms.
