+# ModMan
+
+ModMan is the experimental GUI for OpenAssetTools.
+
+## How do I test it
+
+Currently ModMan is not compiled by default.
+To enable it, you have to generate with the appropriate premake5 flag:
+
+```shell
+# On Windows
+./generate.bat --modman
+
+# On Linux
+./generate.sh --modman
+```
+
+**Before** building the C++ solution, the ui has to be built.
+This will require NodeJS to be installed on your machine.
+
+```shell
+# Download dependencies
+npm --prefix src/ModManUi install
+
+# Build frontend
+npm --prefix src/ModManUi run build
+
+# Optional: Dev Server for UI development
+npm --prefix src/ModManUi run dev
+```
+
+## How does it work
+
+ModMan uses [`webview`](https://github.com/Laupetin/webview) for providing a web frontend as a native application.
+Unlike frameworks like Electron this does not ship a browser engine alongside it, but instead relies on browser APIs of your OS.
+On Windows, this makes use of [WebView2](https://learn.microsoft.com/en-us/microsoft-edge/webview2), on Linux it uses [WebKitGTK](https://webkitgtk.org).
+
+This adds the following dependencies:
+* **Windows**: An up-to-date OS with at the very least Windows10. The WebView2 library for development is downloaded by premake.
+* **Linux**: Developing and using ModMan requires the following dependencies to be installed: `gtk4 webkitgtk-6.0`
