 We are happily accepting code contributions of different types. Here are some hints on this.
 
-## Development environment
-
-For now, there is no included documentation on how to setup your environment best.
-
-You might however have alook at [this repository](https://github.com/christianlupus/nextcloud-docker-debug).
-It describes **one** way to get a running development environment for the app.
-
-## Unit tests and code coverage
-
-Currently there is a github action in place that does automatic unit testing upon pushing to github.
-These tests are generating code coverage reports as well.
-
-Firstly, for each such run (see in the actions view or the PR tests) there is the option to download the code coverage as zipped HTML page.
-Secondly, the [codecov.io service](https://codecov.io/gh/nextcloud/cookbook) is installed, where more details about the coverage can be found.
+Please have a look at the [developer documentation](https://nextcloud.github.io/cookbook/dev/) in general and about [contributing](https://nextcloud.github.io/cookbook/dev/contributing/).

 ## Coding
 The first step, when you want to help with coding on the app, will be to setup your development environment.
 We prepared a [page on the setup](setup) to help you get started with the technical requirements.
+See also the page on [code coverage](code_coverage).
 
 ## Translating
 Feel free to have a look at the [transifex page on the cookbook app](https://www.transifex.com/nextcloud/nextcloud/cookbook/).
 Any translations done there will be synchronized on a nightly base.

+## Documentation
+We also need helpers in writing documentation for various levels and user groups.
+If you think you can help by writing appropriate documentation or tutorials, feel free to step forward.
