-All CRDs of this project are managed in the [catalog](https://github.com/metio/kube-custom-resources-rs/blob/main/code-generator/src/catalog.rs) which contains a long list of projects along with the CRDs they are producing.

We try to sort this list alphabetically to make it easier finding things, but this is not a hard requirement for your contribution. Each entry requires the following details:
 
 - `project_name`: The organization and name of a project, e.g. `prometheus-operator/prometheus-operator` is used for the project at https://github.com/prometheus-operator/prometheus-operator.
-- `license`: The SPDX license identifier for the CRD files. This is usually the same license as the project and the catalog file already contains constants for the most common licenses.

-Certain CRDs cannot be correctly converted to Rust code yet. Make sure that each newly generated resource can be compiled by calling:
-
-```console
-$ ./code-generator/test-custom-resources.sh <feature_name>

-The `<feature_name>` argument corresponds to the newly generated folder in `kube-custom-resources-rs/src` for the new CRDs added by yourself.

-### 5. Adjust Output
-
-By default, we call kopium with the following arguments:
-
-- `--docs`
-- `--filename=...`
-- `--derive=Default`
-- `--derive=PartialEq`
-
-Some CRDs cannot implement the `Default` trait. In those cases, add an `.args` file next to the downloaded `.yaml` file in the catalog and specify the **derive** directives to use (docs and filename will always be set), e.g.:
-
-```
---derive=PartialEq
-```
+### 4. Adjust Output
 
 Some CRDs cannot be converted to Rust code at all. In those cases, add an `.ignore` file next to the downloaded `.yaml` file in the catalog and write the reason why this CRD was ignored into the file, e.g.:
 
 ```
 CRD has no spec field
 ```
