+## Good practices
+
+1. `clone` a repository, do not download the `.zip` file.
+2. `pull` before `push`
+3. Work on your own branch (in your own fork)
+4. Do not `push` to `master`
+5. Do not `push` to `develop`
+6. Stage only 1 file at once using
+```sh
+$ git add myFile.txt
+```
+7. Commit only a few files at once
+8. Submit a PR instead of pushing directly
+9. Always sync your fork before starting to work
+10. `Push` often - avoid conflicts
+

+**A `push` a day keeps the conflict away**
