# Custom GitHub App

Before creating your container, you'll need to create a GitHub app for your organisation.

## Creating a GitHub OAuth app

From GitHub, click on your profile picture and chose "Settings":

![Step 1](/nx-cloud/enterprise/on-premise/images/github_auth_step_1.png)

Then "Developer settings" from the left-hand menu:

![Step 2](/nx-cloud/enterprise/on-premise/images/github_auth_step_2.png)

Then "GitHub Apps":

![Step 3](/nx-cloud/enterprise/on-premise/images/github_custom_app_step_3.avif)

And create a new GitHub app:

![Step 4](/nx-cloud/enterprise/on-premise/images/github_custom_app_step_5.avif)

Give it a name, and a homepage URL. The callback URL is the important bit. It needs to be in this form:

```
[your-nx-cloud-url]/callbacks/github-user

# for example
https://my.nx-enterprise.url:8080/callbacks/github-user
```

Once you create the app, keep a note of the Client ID and App ID:

Then generate a new client secret, and save it somewhere secure (we'll use it in a bit):
