+# What is this?
+
+This directory, along with its fake `daml.yaml` can be populated with symlinks by
+`./scripts/setup-mono-package.sh` to serve as a fake single-dar package containing all the daml in
+Splice such that cross-package changes can be worked on with a tighter feedback loop using the
+Daml Language Server (LSP) in VS Code or other editors, e.g. by running `dpm studio` in this directory
+after having run the script.
+
+You'll also have to remember to re-run the script if you add new `.daml` files to any package.
+
+You should still verify that everything builds/tests for real once you're done of course, but this mode
+of interaction can be very useful to eliminate 12-20 second build cycles and instead get immediate
+feedback from the VS Code extension when working on tests and making changes that would otherwise be in
+their upstream DAR dependencies, for example.
