+## Install or Setup script support
+
+User can have either of the following setup script files in their dotfiles repo:
+
+- install.sh
+- install
+- bootstrap.sh
+- bootstrap
+- script/bootstrap
+- setup.sh
+- setup
+- script/setup
+
+If any of the above files are found in the specified order, Coder will execute the first match, and the rest will be skipped.
+
+The Setup scripts must be executable. If they are not, Coder will not execute them. If the script is not executable, you can make it executable by running:
+
+```bash
+cd <path_to_dotfiles_repo>
+
+chmod +x <script_name>
+
+git commit -m "Make <script_name> executable" <script_name>
+
+git push
+```
