+# Forge MAST Environment Setup
+
+A simple setup script to automatically configure your environment for running Forge with MAST jobs.
+This only applies to Meta internal users.
+
+## Quick Start
+
+⚠️ Important Note: the setup script will clone the forge repository under "/data/users/$USER".
+
+### 1. Run the Setup Script
+
+The `env_setup.sh` script will automatically:
+- ✅ Activate and configure the required conda environment
+- ✅ Clone/update the Forge repository
+- ✅ Install Forge package dependencies
+- ✅ Mount the required oilfs workspace to `/mnt/wsfuse`
+- ✅ Configure your environment for MAST job submission
+
+```bash
+# Make the script executable
+chmod +x .meta/mast/env_setup.sh
+
+# Run the setup
+./.meta/mast/env_setup.sh
+
+```
+
+### 2. Submit MAST job
+
+Use the launch script to submit a MAST job:
+
+```bash
+# Make the launch script executable (first time only)
+chmod +x .meta/mast/launch.sh
+
+# Launch a job with your desired config
+./.meta/mast/launch.sh .meta/mast/qwen3_1_7b_mast.yaml
+```
+
+The launch script will automatically:
+- Navigate to the forge root directory
+- Reinstall the forge package with your latest changes
+- Set the correct PYTHONPATH
+- Launch the MAST job with the specified config
+
+You can run it from anywhere, and it will figure out the correct paths.
