+### Layout Server
 
-The UI scripts all run from the vuu/vuu-ui directory.
+Layout management requires persisting layouts. Layouts can either be persisted locally or remotely. The remote implementation requires spinning up a Springboot server instance, but is more robust and reflective of a real-world application.
 
-```sh
-#from top-level vuu repo (not vuu child directory in repo)
-cd vuu-ui
-npm install
-npm run build
-npm run build:app
-```
+#### Choosing local or remote
 
-You can now open the demo app in your browser at https://127.0.0.1:8443/index.html
+Changing whether local/remote is used is configured with the following flag:
 
-Alternatively, you may choose to run the demo app in Electron. First install Electron in the tools/electron folder:
+1. Open `finos-vuu\vuu-ui\showcase\vite.config.js` (for Showcase), or `finos-vuu\vuu-ui\sample-apps\app-vuu-example\esbuild.mjs` (for sample app)
+2. Set `"process.env.LOCAL"` flag to `true` for local, or `false` for remote
+
+The local implementation is default. It uses browser local storage. If you have chosen the remote implementation, ensure you are running the remote server.
+
+#### Running the remote server
+
+You can run the remote server from IntelliJ or via CLI. Once running, use `http://localhost:8081/api/swagger` to review endpoints and contracts. It uses an in-memory H2 database, and can be accessed at `http://localhost:8081/api/h2-console`.
