+
+## Getting Started
+
+> [!IMPORTANT]
+> If you run into issues, please see our [common issues](#common-issues).
+
+1. Download and extract this repo somewhere on your computer.
+2. Install our [dependencies](#dependencies).
+3. Open the folder you downloaded: **Run the start script and follow the on-screen prompts.** You may disregard any severity warnings you see.
+
+Once your setup process has completed, wait for it to tell you the world has started before trying to play.
+
+The server includes its own client, so you don't have to download anything else!
+
+## Dependencies
+
+- Git CLI - Windows users: [git-scm](https://git-scm.com/)
+- [NodeJS 22](https://nodejs.org/)
+- [Java 17 or newer](https://adoptium.net/)
+
+> [!TIP]
+> If you're using VS Code (recommended), [we have an extension to install on the marketplace.](https://marketplace.visualstudio.com/items?itemName=2004scape.runescriptlanguage)
+
+## Workflow
+
+Content developers should run `npm start`. The server will watch for changes to scripts and configs, then automatically repack everything.
+
+Engine developers should run `npm run dev`. This does what `npm start` does above, but also completely restarts the server when engine code has changed.
+
+## Common Issues
+
+* `bad option: --import`  
+
+You are using an older version of Node. Reinstall and re-run.
+
+* `'"java"' is not recognized as an internal or external command`  
+
+You do not have Java installed.
+
+* `XXXXX has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0`  
+
+You are using Java 8 or Java 11. If you have multiple Java versions, you will need to set `JAVA_PATH=path-to-java.exe` in your .env file.
