+# Castorsrm
+
+Rice shirt rice money :(
+
+## Installation
+
+This project uses Bun for dependency management and Node.js (or Bun on UNIX platforms) for the app execution.
+
+```bash
+git clone https://git.tretrauit.me/tretrauit/castorsrm
+cd castorsrm
+bun install
+bun run dev
+# or execute "bun run dev-bun" to start the application with Bun instead
+# Note that Bun will not work correctly with Playwright on Windows.
+```
+
+## Configuration
+
+On the first launch, it'll generate a `config.json` file. You can change the application settings by editing that file.
+
