+
+## Was ist das
+
+GammaLauncher is a simple application that allows to launch vvvv gamma instances with specific arguments from a simple GUI.
+
+## Usage
+
+When the application first starts, it generates a `config.xml` file next to it. This file contains path to your gamma insatallations (should be `C:\Program Files\vvvv`), as well as your repositories folder, if you're using that feature. You can customize those paths if needed by editing the config file.
+
+Then, simply pick the specific gamma version you wanna start from the dropdown menu, and tick the options you wanna use :
+
+- Allow multiple : allows to start more than one `vvvv.exe` at once
+- Use repositories : this will ovewrite packages in the default package folder with the ones in your repositories folder, if you specify one. This is usefull if you're building libraries for gamma.
+
+## How to get it
+
+Get the latest version [here](http://sebescudie.fr/releases/gammalauncher/gammalauncher_1.0.7z), or clone the repo and build the app yourself. If you do so, don't forget to copy the `ico.ico` file to your output dir, otherwise the app won't start.
