 1. Go [here](https://github.com/new) to create a new repository under your account. Pick a name (e.g. `bustub-private`) and select **Private** for the repository visibility level.
 2. On your development machine, create a bare clone of the public BusTub repository:
-   ```
+   ```console
    $ git clone --bare https://github.com/cmu-db/bustub.git bustub-public
    ```
 3. Next, [mirror](https://git-scm.com/docs/git-push#Documentation/git-push.txt---mirror) the public BusTub repository to your own private BusTub repository. Suppose your GitHub name is `student` and your repository name is `bustub-private`. The procedure for mirroring the repository is then:
-   ```
+   ```console
    $ cd bustub-public
 
    # If you pull / push over HTTPS

    $ git push [email protected]:student/bustub-private.git master

    This copies everything in the public BusTub repository to your own private repository. You can now delete your local clone of the public repository:
-   ```
+   ```console
    $ cd ..
    $ rm -rf bustub-public
    ```
 4. Clone your private repository to your development machine:
-   ```
+   ```console
    # If you pull / push over HTTPS
    $ git clone https://github.com/student/bustub-private.git
 
    # If you pull / push over SSH
    $ git clone [email protected]:student/bustub-private.git
    ```
 5. Add the public BusTub repository as a second remote. This allows you to retrieve changes from the CMU-DB repository and merge them with your solution throughout the semester:
-   ```
+   ```console
    $ git remote add public https://github.com/cmu-db/bustub.git
    ```
    You can verify that the remote was added with the following command:
-   ```
+   ```console
    $ git remote -v
    origin	https://github.com/student/bustub-private.git (fetch)
    origin	https://github.com/student/bustub-private.git (push)
    public	https://github.com/cmu-db/bustub.git (fetch)
    public	https://github.com/cmu-db/bustub.git (push)
    ```
 6. You can now pull in changes from the public BusTub repository as needed with:
-   ```
+   ```console
    $ git pull public master
    ```
 7. **Disable GitHub Actions** from the project settings of your private repository, otherwise you may run out of GitHub Actions quota.
