+# Conan Package Registry
+
+Publish [Conan](https://conan.io/) packages for your user or organization.
+
+## Requirements
+
+To work with the Conan package registry, you need to use the [conan](https://conan.io/downloads.html) command line tool to consume and publish packages.
+
+## Configuring the package registry
+
+To register the package registry you need to configure a new Conan remote:
+
+```shell
+conan remote add {remote} https://gitea.example.com/api/packages/{owner}/conan
+conan user --remote {remote} --password {password} {username}
+```
+
+| Parameter  | Description |
+| -----------| ----------- |
+| `remote`   | The remote name. |
+| `username` | Your Gitea username. |
+| `password` | Your Gitea password. If you are using 2FA or OAuth use a [personal access token](development/api-usage.md#authentication) instead of the password. |
+| `owner`    | The owner of the package. |
+
+For example:
+
+```shell
+conan remote add gitea https://gitea.example.com/api/packages/testuser/conan
+conan user --remote gitea --password password123 testuser
+```
+
+## Publish a package
+
+Publish a Conan package by running the following command:
+
+```shell
+conan upload --remote={remote} {recipe}
+```
+
+| Parameter | Description |
+| ----------| ----------- |
+| `remote`  | The remote name. |
+| `recipe`  | The recipe to upload. |
+
+For example:
+
+```shell
+conan upload --remote=gitea ConanPackage/1.2@gitea/final
+```
+
+You cannot publish a file with the same name twice to a package. You must delete the existing package or file first.
+
+The Gitea Conan package registry has full [revision](https://docs.conan.io/en/latest/versioning/revisions.html) support.
+
+## Install a package
+
+To install a Conan package from the package registry, execute the following command:
+
+```shell
+conan install --remote={remote} {recipe}
+```
+
+| Parameter | Description |
+| ----------| ----------- |
+| `remote`  | The remote name. |
+| `recipe`  | The recipe to download. |
+
+For example:
+
+```shell
+conan install --remote=gitea ConanPackage/1.2@gitea/final
+```
+
+## Supported commands
+
+```
+conan install
+conan get
+conan info
+conan search
+conan upload
+conan user
+conan download
+conan remove
+```
