# GitHub and GitHub Enterprise Server
Most of the information on this page is meant for users who want to self-host Renovate on GitHub or GitHub Enterprise Server.
## Easiest way to run Renovate
For users on GitHub Cloud (`github.com`), the easiest way to get started is to install [the Mend Renovate app](https://github.com/marketplace/renovate) from the GitHub marketplace.
When you use the app, Mend will:
- authenticate the Renovate app to GitHub
- keep the tokens safe
- maintain and update the Renovate version used
If you self-host Renovate you must do the things listed above yourself.
Self-hosting is meant for users with advanced use cases, or who want to be in full control of the bot and the environment it runs in.
We recommend most users install the Mend Renovate app.
Read the [Security and Permissions](../../../security-and-permissions.md) page to learn about the Security and Permissions needed for the Mend Renovate app.
After you installed the hosted app, please read the [reading list](../../../reading-list.md) to learn how to use and configure Renovate.
## Authentication
First, create a [fine-grained](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#creating-a-fine-grained-personal-access-token) _or_ a [classic](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token#creating-a-personal-access-token-classic) PAT.
The PAT must have the `repo` scope.
If you want Renovate to also update your GitHub Action files, you must grant the `workflow` scope.
Read the [GitHub Docs, about Personal Access Tokens](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#about-personal-access-tokens) to learn more about PATs.
Let Renovate use your PAT by doing _one_ of the following:
- Set your PAT as a `token` in your `config.js` file
- Set your PAT as an environment variable `RENOVATE_TOKEN`
- Set your PAT when you run Renovate in the CLI with `--token=`
Remember to set `platform=github` somewhere in your Renovate config file.
If you use GitHub Enterprise Server then `endpoint` must point to `https://github-enterprise.example.com/api/v3/`.
You can choose where you want to set `endpoint`:
- In your `config.js` file
- In a environment variable
- In a CLI parameter

!!! tip "Labels and forking mode"
If you're self-hosting Renovate on GitHub.com with GitHub Actions in forking mode, and want Renovate to apply labels then you must give the PAT `triage` level rights on `issues`.
The `triage` level allows the PAT to apply/dismiss existing labels.
## Running using a fine-grained token
### Permissions
A fine-grained token must have these permissions:
| Permission | Access | Level |
| ------------------- | ---------------- | ------------------------------ |
| `Members` | `Read-only` | _Organization_ |
| `Commit statuses` | `Read and write` | _Repository_ or _Organization_ |
| `Contents` | `Read and write` | _Repository_ or _Organization_ |
| `Dependabot alerts` | `Read-only` | _Repository_ or _Organization_ |
| `Issues` | `Read and write` | _Repository_ or _Organization_ |
| `Pull requests` | `Read and write` | _Repository_ or _Organization_ |
| `Workflows` | `Read and write` | _Repository_ or _Organization_ |
<!-- prettier-ignore -->
!!! tip "Use a bot role account"
Consider creating a GitHub App to use instead of using your own GitHub user account.
## Running as a GitHub App
Instead of a bot account with a Personal Access Token you can run `renovate` as a self-hosted [GitHub App](https://docs.github.com/en/developers/apps/getting-started-with-apps).
When creating the GitHub App give it the following permissions:
| Permission | Scope |
| ----------------- | ---------------- |
| Checks | `read` + `write` |
| Commit statuses | `read` + `write` |
| Contents | `read` + `write` |
| Issues | `read` + `write` |
| Pull requests | `read` + `write` |
| Workflows | `read` + `write` |
| Administration | `read` |
| Dependabot alerts | `read` |
| Members | `read` |
| Metadata | `read` |
Other values like Homepage URL, User authorization callback URL and webhooks can be disabled or filled with dummy values.
Inside your `config.js` you need to set the following values, assuming the name of your app is `self-hosted-renovate`:
**`token:"ghs_123exampletoken"`**
You must use a [GitHub App Installation token](https://docs.github.com/en/developers/apps/building-github-apps/authenticating-with-github-apps#authenticating-as-an-installation).
Previously, the token had to be prefixed with `x-access-token:`.
We recommend you replace any prefixed tokens with normal tokens.
We will drop support for prefixed tokens in the future.
Any tokens that do not start with `ghs_` (for example tokens from GitHub Enterprise Server versions before version `3.2`) must be prefixed with `x-access-token:`.
<!-- prettier-ignore -->
!!! note
The installation tokens expire after 1 hour and need to be regenerated regularly.
Alternatively as environment variable `RENOVATE_TOKEN`, or via CLI `--token=`.
<!-- prettier-ignore -->
!!! tip "Third-party tools to regenerate installation tokens"
If you're self-hosting Renovate within a GitHub Actions workflow, then you can use the [`actions/create-github-app-token`](https://github.com/actions/create-github-app-token) action.
If you use Node.js/CLI, then you can use the [`github-app-installation-token`](https://github.com/gagoar/github-app-installation-token) package.
If you use Docker, then you can use the [`mshekow/github-app-installation-token`](https://github.com/MShekow/github-app-installation-token) image.
**`repositories: ["orgname/repo-1","orgname/repo-2"]`**
List of repositories to run on.
Alternatively as comma-separated environment variable `RENOVATE_REPOSITORIES`.
The GitHub App installation token is scoped at most to a single organization and running on multiple organizations requires multiple invocations of `renovate` with different `token` and `repositories` parameters.
**`username:"self-hosted-renovate[bot]"`** (optional, autodetected if not supplied)
The slug name of your app with `[bot]` appended
**`gitAuthor:"Self-hosted Renovate Bot <123456+self-hosted-renovate[bot]@users.noreply.github.enterprise.com>"`** (optional, autodetected if not supplied)
The [GitHub App associated email](https://github.community/t/logging-into-git-as-a-github-app/115916/2) to match commits to the bot.
It needs to have the user id _and_ the username followed by the `users.noreply.`-domain of either github.com or the GitHub Enterprise Server.
A way to get the user id of a GitHub app is to [query the user API](https://docs.github.com/en/rest/reference/users#get-a-user) at `api.github.com/users/self-hosted-renovate[bot]` (github.com) or `github.enterprise.com/api/v3/users/self-hosted-renovate[bot]` (GitHub Enterprise Server).
## Package Registry Credentials
When Renovate runs against repositories on `github.com`, and the environment variable `RENOVATE_X_GITHUB_HOST_RULES` is set, then Renovate automatically provisions `hostRules` for these GitHub Packages registries using the platform token:
- `ghcr.io`
- `maven.pkg.github.com`
- `npm.pkg.github.com`
- `nuget.pkg.github.com`
- `rubygems.pkg.github.com`
<!-- prettier-ignore -->
!!! warning
We reverted the Package Registry Credentials feature to experimental mode, because users reported it's not working correctly with app tokens.
## Features awaiting implementation
- The `automergeStrategy` configuration option has not been implemented for this platform, and all values behave as if the value `auto` was used. Renovate will use the merge strategy configured in the GitHub repository itself, and this cannot be overridden yet
