+## Working with submodules 
+This project uses [git submodules](https://git-scm.com/book/en/v2/Git-Tools-Submodules) . In particular netbeans and netbeans-l10n are submodules pointing to specific commits in their respective repositories .
+### Switching Branches 
+Add the --recurse-submodules  flag to the git checkout command to update the submodules during the checkout.
+```bash
+git checkout --recurse-submodules <branch_name>
+```
+Note:- Merging branches with submodules pointing to different commits can be tricky. Refer the [git submodules](https://git-scm.com/book/en/v2/Git-Tools-Submodules) for more details on the same.
+### Changing submodules versions 
+```bash
+# Fetching changes from remote submodule repositories 
+git submodule update --remote   
+# Changing the submodule version
+cd netbeans
+git checkout <commit_hash>
+cd ..
+# Committing the submodule version 
+git add netbeans
+git commit -m "Updated netbeans"
+```
