+
+To work with the Helm Chart registry use a simple HTTP client like `curl` or the [`helm cm-push`](https://github.com/chartmuseum/helm-push/) plugin.
+
+## Publish a package
+
+Publish a package by running the following command:
+
+```shell
+curl --user {username}:{password} -X POST --upload-file ./{chart_file}.tgz https://gitea.example.com/api/packages/{owner}/helm/api/charts
+```
+
+or with the `helm cm-push` plugin:
+
+```shell
+helm repo add  --username {username} --password {password} {repo} https://gitea.example.com/api/packages/{owner}/helm
+helm cm-push ./{chart_file}.tgz {repo}
+```
+
+| Parameter    | Description |
+| ------------ | ----------- |
+| `username`   | Your Gitea username. |
+| `password`   | Your Gitea password or a personal access token. |
+| `repo`       | The name for the repository. |
+| `chart_file` | The Helm Chart archive. |
+| `owner`      | The owner of the package. |
+
+## Install a package
+
+To install a Helm char from the registry, execute the following command:
+
+```shell
+helm repo add  --username {username} --password {password} {repo} https://gitea.example.com/api/packages/{owner}/helm
+helm repo update
+helm install {name} {repo}/{chart}
+```
+
+| Parameter  | Description |
+| ---------- | ----------- |
+| `username` | Your Gitea username. |
+| `password` | Your Gitea password or a personal access token. |
+| `repo`     | The name for the repository. |
+| `owner`    | The owner of the package. |
