 ## Customization for Your Labs
 
 ### Add Additional R Packages
+
 Modify the `Dockerfile` (before `USER ${NB_UID}`):
-```dockerfile
+
+``` dockerfile
 RUN R -e "install.packages(c('your_package'), repos='http://cran.rstudio.com/')"
 ```
 
 Then rebuild:
-```bash
+
+``` bash
 docker build -t jupyterhub-student:latest -f Dockerfile .
 docker-compose restart jupyterhub
 ```
 
 ### Add Python Packages
+
 Add to the `Dockerfile` (before `USER ${NB_UID}`):
-```dockerfile
+
+``` dockerfile
 RUN pip install numpy pandas matplotlib seaborn
 ```
 
 ### Distribute Files to Students
+
 Create a `files_lab/` directory and add to the `Dockerfile`:
-```dockerfile
+
+``` dockerfile
 COPY files_lab/ /home/${NB_USER}/lab/
 RUN chown -R ${NB_UID}:${NB_GID} /home/${NB_USER}/lab
 ```
 
 ### Change Port (if 8000 is occupied)
+
 Modify in `docker-compose.yml`:
-```yaml
+
+``` yaml
 ports:
   - "8001:8000"  # Accessible on localhost:8001
 ```
