-### Work on GitHub
-
-DSP-APP has two main branches at the moment:
-
-#### "main" branch
-
-- use the branch "main" to work on the DSP-ADMIN app. Any changes should be created in branches from "main" and should be merged into the "main" branch.
-
-#### "develop" branch
-
-- use the branch "develop" to work on the whole DSP-APP app (admin + research parts). Any new developments should be created in branches from "develop" and should be merged into the "develop" branch.

 ## Development server
 
-Run `ng serve` or `npm run start` for a dev server. Navigate to `http://0.0.0.0:4200/`. The app will automatically reload if you change any of the resource files.
+DSP-APP is built with [Angular](https://angular.io/) and uses [NPM](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm).

+You have to install the corresponding packages with `npm i`. Now you have to possibilites to run the application in developer mode:
+
+- With a local installed [DSP-API environment](https://docs-api.dasch.swiss/04-publishing-deployment/getting-started/) run `ng serve` or `npm run start`.
+- If you want to connect to the DSP-API on our test server run `ng serve --configuration=test-server` or `npm run start-with-test-server`. Please consider which version of DSP-API is currently running on the test server (see webapi: <https://api.test.dasch.swiss/version>). With this solution you will also have access to all the representation files.

+In both case navigate to `http://0.0.0.0:4200/`. The app will automatically reload if you change any of the resource files.
