 Quick start
 1. Place challenge files in ./challenge
 2. Build and start the lab (background):
+   ```
     docker compose up --build -d
+   ```
 3. Enter an interactive shell inside the running container:
+   ```
     docker compose exec exploit-lab /bin/bash
+   ```
    (or as mapped host user)
+   ```
     docker compose exec --user 1000:1000 exploit-lab /bin/bash
+   ```
 4. Stop and remove containers:
+   ```
     docker compose down
+   ```
 
 Notes about safety & file locations
 - Mounted challenge directory is read-only inside the container at /home/kali/challenge.

 Rebuilding or updating tools
 - After editing the Dockerfile, rebuild:
-  docker compose build --no-cache
-  docker compose up -d
+  `docker compose build --no-cache`
+  `docker compose up -d`
 
 Networking
 - By default runtime network is disabled (network_mode: "none") to reduce risk. If you need network, edit docker-compose.yml and remove or change network_mode, then rebuild.
 
 Common commands
-- Start foreground (logs): docker compose up --build
-- Start background: docker compose up -d
-- Exec shell: docker compose exec exploit-lab /bin/bash
-- Run one-off shell: docker compose run --rm exploit-lab /bin/bash
-- Get logs: docker compose logs -f
-- Rebuild image: docker compose build --no-cache
-- Stop and remove: docker compose down

 Troubleshooting
 - Build errors about pip/PEP 668: the Dockerfile uses a Python virtualenv (/opt/venv). If you change Python steps, prefer venv over system pip.
