+# Pub Packages Repository
+
+Publish [Pub](https://dart.dev/guides/packages) packages for your user or organization.
+
+**Table of Contents**
+
+{{< toc >}}
+
+## Requirements
+
+To work with the Pub package registry, you need to use the tools [dart](https://dart.dev/tools/dart-tool) and/or [flutter](https://docs.flutter.dev/reference/flutter-cli).
+
+The following examples use dart.
+
+## Configuring the package registry
+
+To register the package registry and provide credentials, execute:
+
+```shell
+dart pub token add https://gitea.example.com/api/packages/{owner}/pub
+```
+
+| Placeholder  | Description |
+| ------------ | ----------- |
+| `owner`      | The owner of the package. |
+
+You need to provide your [personal access token]({{< relref "doc/developers/api-usage.en-us.md#authentication" >}}).
+
+## Publish a package
+
+To publish a package, edit the `pubspec.yaml` and add the following line:
+
+```yaml
+publish_to: https://gitea.example.com/api/packages/{owner}/pub
+```
+
+| Placeholder  | Description |
+| ------------ | ----------- |
+| `owner`      | The owner of the package. |
+
+Now you can publish the package by running the following command:
+
+```shell
+dart pub publish
+```
+
+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 Pub package from the package registry, execute the following command:
+
+```shell
+dart pub add {package_name} --hosted-url=https://gitea.example.com/api/packages/{owner}/pub/
+```
+
+| Parameter         | Description |
+| ----------------- | ----------- |
+| `owner`           | The owner of the package. |
+| `package_name`    | The package name. |
+
+For example:
+
+```shell
+# use latest version
+dart pub add mypackage --hosted-url=https://gitea.example.com/api/packages/testuser/pub/
+# specify version
+dart pub add mypackage:1.0.8 --hosted-url=https://gitea.example.com/api/packages/testuser/pub/
+```
