+## Editing Source Code
+
+### Visual Studio Code
+
+You can edit OCaml code after you have built the `Package-Stage04-FullFlavor` target.
+
+In Visual Studio Code:
+
+1. Go to View > Command Palette and select `OCaml: Select a Sandbox for this Workspace`.
+2. Choose "Custom"
+3. Enter the following (with the paths changed to reflect your project directory, and the correct DkML version number):
+
+   ```powershell
+   Y:\source\dkml\build\pkg\bump\.ci\sd4\bs\bin\opam.exe list --switch 2.1.0 --root Y:/source/dkml/build/pkg/bump/.ci/o -- $prog $args
+   ```
+
+### Dune Build
+
+You can go into directories to build each project you want to edit. For example:
+
+```powershell
+cd build\_deps\dkml-runtime-apps-src
+Y:\source\dkml\build\pkg\bump\.ci\sd4\bs\bin\opam.exe exec --switch 2.1.0 --root Y:\source\dkml\build\pkg\bump\.ci\o -- dune build
+```
+
+### Git
+
+You can do `git commit` in each `build/_deps/*-src` directory. There are `Package-Stage*` targets that will push in changes
+at the appropriate times.
