+# MP1 Usage
+
+## Running MP1
+
+Use `run_mp.sh <1..10|all>` to start the socket servers on specific VMs:
+
+```bash
+./run_mp.sh 3
+./run_mp.sh all
+```
+
+Use `kill_mp.sh <1..10|all>` to stop the socket servers on specific VMs:
+
+```bash
+./kill_mp.sh 3
+./kill_mp.sh all
+```
+
+Use `deploy_mp.sh` to kill the servers on all VMs, pull the latest version of `main`, and restart every server using `run_mp.sh`:
+
+```bash
+./deploy_mp.sh
+```
+
+After deployment, the `grepp` command should be available. Use it like regular `grep`, but it searches the log files across all ten machines:
+
+```bash
+grepp ERROR
+grepp -E 'GET|POST'
+```
+
+## Testing
+
+Run `test.py` on your local machine:
+
+```bash
+python3 test.py
+```
+
+The script generates test log files, runs `grepp` with the `-t` flag, checks the output for correctness, and deletes the generated test files afterward.
