+## Documentation
 
-## Publishing New Version
+The documentation for all modules are available through `ansible-doc`.
 
+Sample: `ansible-doc hetzner.hcloud.hcloud_server` shows the documentation for the `hcloud_server` module.
 
-TBD	Basic instructions without release branches:
+For all modules that were part of Ansible directly (before Ansible 2.11) we also have the documentation published in the
+Ansible documentation: https://docs.ansible.com/ansible/latest/collections/hetzner/hcloud/
 
-1. Create `changelogs/fragments/<version>.yml` with `release_summary:` section (which must be a string, not a list).
-2. Run `antsibull-changelog release --collection-flatmap yes`
-3. Make sure `CHANGELOG.rst` and `changelogs/changelog.yaml` are added to git, and the deleted fragments have been removed.
-4. Tag the commit with `<version>`. Push changes and tag to the main repository.
+# Development
+
+## Requirements
+
+You should place the collection (clone the repository) into the Ansible collection path. Normally this
+is `~/.ansible/collections/ansible_collections/<namespace>/<collection`, so for our collection it would
+be: `~/.ansible/collections/ansible_collections/hetzner/hcloud`.
+
+```
+git clone git@github.com:ansible-collections/hetzner.hcloud.git ~/.ansible/collections/ansible_collections/hetzner/hcloud
+```
+
+After this you just need `ansible` installed.
+
+## Testing
+
+Testing is done via `ansible-test`. Make sure to have a `cloud-config-hcloud.ini` file in `tests/integration` which
+contains the hcloud API token:
+
+```
+[default]
+hcloud_api_token=<token>
+```
+
+After this you should be able to use `ansible-test integration` to perform the integration tests for a specific module.
+Sample:
+
+```
+ansible-test integration --color --local  -vvv hcloud_server // Executed all integration tests for hcloud_server module
+```
+
+## Releasing a new version
+
+### Generating changelog from fragments
+
+1. Check if the changelog fragments are available (there should be files in `changelogs/fragments`)
+2. Run `antsibull-changelog release --version <version>`, it should remove all fragments and change
+   the `changelogs/changlog.yaml` and `CHANGELOG.rst`
+3. Push the changes to the master branch
+4. Tag the release through the Github UI, after this the Github Actions will run and publish the collection to Ansible
