 ## Common Issues
 
 - If you get errors when building after switching branches, you may have to remove or update tree-sitter submodules. You can update submodules by running
-```sh
-$ git submodule sync; git submodule update --init
-```
+    ```sh
+    git submodule sync; git submodule update --init
+    ```
 - Make sure to not use the `--remote` flag. To remove submodules look inside the `.gitmodules` and remove directories that are not present inside of it.
 
 - If a parser is segfaulting or you want to remove the parser, make sure to remove the submodule *and* the compiled parser in `runtime/grammar/<name>.so`
 
 - The indents query is `indents.toml`, *not* `indents.scm`. See [this](https://github.com/helix-editor/helix/issues/114) issue for more information.
