+# Container Registry
+
+Publish [Open Container Initiative](https://opencontainers.org/) compliant images for your user or organization.
+The container registry follows the OCI specs and supports all compatible images like [Docker](https://www.docker.com/) and [Helm Charts](https://helm.sh/).

+
+## Requirements
+
+To work with the Container registry, you can use the tools for your specific image type.
+The following examples use the `docker` client.
+
+## Login to the container registry
+
+To push an image or if the image is in a private registry, you have to authenticate:
+
+```shell
+docker login gitea.example.com
+```
+
+## Image naming convention
+
+Images must follow this naming convention:
+
+`{registry}/{owner}/{image}`
+
+For example, these are all valid image names for the owner `testuser`:
+
+`gitea.example.com/testuser/myimage`
+
+`gitea.example.com/testuser/my-image`
+
+`gitea.example.com/testuser/my/image`
+
+**NOTE:** The registry only supports case-insensitive tag names. So `image:tag` and `image:Tag` get treated as the same image and tag.
+
+## Push an image
+
+Push an image by executing the following command:
+
+```shell
+docker push gitea.example.com/{owner}/{image}:{tag}
+```
+
+| Parameter | Description |
+| ----------| ----------- |
+| `owner`   | The owner of the image. |
+| `image`   | The name of the image. |
+| `tag`     | The tag of the image. |
+
+For example:
+
+```shell
+docker push gitea.example.com/testuser/myimage:latest
+```
+
+## Pull an image
+
+Pull an image by executing the following command:
+
+```shell
+docker pull gitea.example.com/{owner}/{image}:{tag}
+```
+
+| Parameter | Description |
+| ----------| ----------- |
+| `owner`   | The owner of the image. |
+| `image`   | The name of the image. |
+| `tag`     | The tag of the image. |
+
+For example:
+
+```shell
+docker pull gitea.example.com/testuser/myimage:latest
+```
