Ensure that you have npm installed globally; this doesn't use the
distribution provided by Pigweed yet.
Open the pigweed/pw_ide/vscode directory directly in Visual Studio Code.
Run npm install to add all dependencies.
Run "Run Extension" in the "Run and Debug" sidebar, or simply hit F5. A new
Visual Studio Code window will open with the extension installed.
Make changes. The build will update automatically. Click the little green
circle-with-an-arrow icon at the top of your development window to update
the extension development host with the new build.
Building
Install the build tool: npm install -g @vscode/vsce
