 # Best practices
 
 * `pull` before `push`
-
 * Work on your <font color="red">own</font> branch (in your own fork), and **not** on `master` and **not** on `develop`
-
 * Do **not push** to `master`, but **submit a PR**
-
 * Get your code **reviewed** by your peers (submit a PR!)
-
 * Submit a PR **often**!
-
 * `clone` a repository, do not download the `.zip` file.
-
-
 * Do **not** combine `git` commands
    ```bash
    $ git commit -am "myMessage" # do not do this
    ```
-
 * Stage only 1 file at once using
-
    ```bash
    $ git add myFile.md
    ```
-
 * Commit **only a few files** at once (after multiple separate `git add` commands)
-
 * `Push` often - avoid conflicts
 
 Remember: **A `push` a day keeps conflicts away!**
