 CodeQL workspaces and query resolution

   Note
 
-  Source dependencies are CodeQL packs that are resolved from the filesystem. They might be in the same CodeQL workspace, or specified as a path option in the ``--additional-packs`` argument. Source dependencies override any dependencies found in the local package cache and version constraints are ignored. This ensures that during local development version mismatches can be ignored.
+  Source dependencies are CodeQL packs that are resolved from the local file system. These dependencies can be in the same CodeQL workspace, or specified as a path option using the ``--additional-packs`` argument. When you compile and run queries locally, source dependencies override any dependencies found in the local package cache as well as version constraints defined in the ``qlpack.yml``.
+
+  This is particularly useful in the following situations:
+
+  - One of the dependencies of the query pack you are running is not yet published. Resolving from source is the only way to refernce that pack.
+  - You are making changes to multiple packs at the same time and want to test them together. Resolving from source ensures that you are using the version of the pack with your changes in it.
