+# NuGet Package Registry
+
+Publish [NuGet](https://www.nuget.org/) packages for your user or organization. The package registry supports the V2 and V3 API protocol and you can work with [NuGet Symbol Packages](https://docs.microsoft.com/en-us/nuget/create-packages/symbol-packages-snupkg) too.
+
+## Requirements
+
+To work with the NuGet package registry, you can use command-line interface tools as well as NuGet features in various IDEs like Visual Studio.
+More information about NuGet clients can be found in [the official documentation](https://docs.microsoft.com/en-us/nuget/install-nuget-client-tools).
+The following examples use the `dotnet nuget` tool.
+
+## Configuring the package registry
+
+To register the package registry you need to configure a new NuGet feed source:
+
+```shell
+dotnet nuget add source --name {source_name} --username {username} --password {password} https://gitea.example.com/api/packages/{owner}/nuget/index.json
+```
+
+| Parameter     | Description |
+| ------------- | ----------- |
+| `source_name` | The desired source 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
+dotnet nuget add source --name gitea --username testuser --password password123 https://gitea.example.com/api/packages/testuser/nuget/index.json
+```
+
+You can add the source without credentials and use the [`--api-key`](https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-nuget-push) parameter when publishing packages. In this case you need to provide a [personal access token](development/api-usage.md#authentication).
+
+## Publish a package
+
+Publish a package by running the following command:
+
+```shell
+dotnet nuget push --source {source_name} {package_file}
+```
+
+| Parameter      | Description |
+| -------------- | ----------- |
+| `source_name`  | The desired source name. |
+| `package_file` | Path to the package `.nupkg` file. |
+
+For example:
+
+```shell
+dotnet nuget push --source gitea test_package.1.0.0.nupkg
+```
+
+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:
+
+```
+https://gitea.example.com/api/packages/{owner}/nuget/symbols
+```
+
+| Parameter | Description |
+| --------- | ----------- |
+| `owner`   | The owner of the package registry. |
+
+For example:
+
+```
+https://gitea.example.com/api/packages/testuser/nuget/symbols
+```
+
+## Install a package
+
+To install a NuGet package from the package registry, execute the following command:
+
+```shell
+dotnet add package --source {source_name} --version {package_version} {package_name}
+```
+
+| Parameter         | Description |
+| ----------------- | ----------- |
+| `source_name`     | The desired source name. |
+| `package_name`    | The package name. |
+| `package_version` | The package version. |
+
+For example:
+
+```shell
+dotnet add package --source gitea --version 1.0.0 test_package
+```
+
+## Supported commands
+
+```
+dotnet add
+dotnet nuget push
+dotnet nuget delete
+```
