+# Composer Packages Repository
+
+Publish [Composer](https://getcomposer.org/) packages for your user or organization.
+
+**Table of Contents**
+
+{{< toc >}}
+
+## Requirements
+
+To work with the Composer package registry, you can use [Composer](https://getcomposer.org/download/) to consume and a HTTP upload client like `curl` to publish packages.
+
+## Publish a package
+
+To publish a Composer package perform a HTTP PUT operation with the package content in the request body.
+The package content must be the zipped PHP project with the `composer.json` file.
+You cannot publish a package if a package of the same name and version already exists. You must delete the existing package first.
+
+```
+PUT https://gitea.example.com/api/packages/{owner}/composer
+```
+
+| Parameter  | Description |
+| ---------- | ----------- |
+| `owner`    | The owner of the package. |
+
+If the `composer.json` file does not contain a `version` property, you must provide it as a query parameter:
+
+```
+PUT https://gitea.example.com/api/packages/{owner}/composer?version={x.y.z}
+```

+
+```json
+{

+# 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/).
+
+**Table of Contents**
+
+{{< toc >}}
+
+## 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:

+# npm Packages Repository
+
+Publish [npm](https://www.npmjs.com/) packages for your user or organization.

+
+## Configuring the package registry
+
+To register the package registry you need to configure a new package source.
+
+```shell
+npm config set {scope}:registry https://gitea.example.com/api/packages/{owner}/npm/

+npm config set -- '//gitea.example.com/api/packages/testuser/npm/:_authToken' "personal_access_token"
+```
+
+or without scope:
+
+```shell
+npm config set registry https://gitea.example.com/api/packages/testuser/npm/
+npm config set -- '//gitea.example.com/api/packages/testuser/npm/:_authToken' "personal_access_token"
+```
+
+## Publish a package
+
+Publish a package by running the following command in your project:

+```
+
+You cannot publish a package if a package of the same name and version already exists. You must delete the existing package first.
+
+### Symbol Packages
+
+The NuGet package registry has build support for a symbol server. The PDB files embedded in a symbol package (`.snupkg`) can get requested by clients.
+To do so, register the NuGet package registry as symbol source:

+# PyPI Packages Repository
+
+Publish [PyPI](https://pypi.org/) packages for your user or organization.
+
+**Table of Contents**
+
+{{< toc >}}
+
+## Requirements
+
+To work with the PyPI package registry, you need to use the tools [pip](https://pypi.org/project/pip/) to consume and [twine](https://pypi.org/project/twine/) to publish packages.
+
+## Configuring the package registry
+
+To register the package registry you need to edit your local `~/.pypirc` file. Add
+
+```ini
+[distutils]
+index-servers = gitea
+
+[gitea]
+repository = https://gitea.example.com/api/packages/{owner}/pypi
+username = {username}
+password = {password}
+```
+
+| Placeholder  | Description |
+| ------------ | ----------- |
+| `owner`      | The owner of the package. |
+| `username`   | Your Gitea username. |
+| `password`   | Your Gitea password or a [personal access token]({{< relref "doc/developers/api-usage.en-us.md#authentication" >}}). |
+
+## Publish a package
+
+Publish a package by running the following command:
+
+```shell
+python3 -m twine upload --repository gitea /path/to/files/*
+```
+
+The package files have the extensions `.tar.gz` and `.whl`.
+
+You cannot publish a package if a package of the same name and version already exists. You must delete the existing package first.
+
+## Install a package
+
+To install a PyPI package from the package registry, execute the following command:
+
+```shell
+pip install --index-url https://{username}:{password}@gitea.example.com/api/packages/{owner}/pypi/simple --no-deps {package_name}
+```

+| ----------------- | ----------- |
+| `username`        | Your Gitea username. |
+| `password`        | Your Gitea password or a personal access token. |
+| `owner`           | The owner of the package. |
+| `package_name`    | The package name. |
+
+For example:
+
+```shell
+pip install --index-url https://testuser:password123@gitea.example.com/api/packages/testuser/pypi/simple --no-deps test_package
