 First, change to the root directory of your site:
 
-```
+```bash
 cd /path/to/my-existing-site

 ### Previous use of Docsy theme as git clone
 
 Simply remove the subdirectory `docsy` inside your `themes` directory: 
 
-```
+```bash
 rm -rf themes/docsy
 ```
 
 ### Previous use of Docsy theme as git submodule
 
 If your Docsy theme was installed as submodule, use git's `rm` subcommand to remove the subdirectory `docsy` inside your `themes` directory: 
 
-```
+```bash
 git rm -rf themes/docsy
 ```
 
 You are now ready to commit your changes to your repository:
