+
+## OIDC Configuration
+
+WYGIWYH supports login via OpenID Connect (OIDC) through `django-allauth`. This allows users to authenticate using an external OIDC provider.
+
+> [!NOTE]
+> Currently only OpenID Connect is supported as a provider, open an issue if you need something else.
+
+To configure OIDC, you need to set the following environment variables:
+
+| Variable             | Description                                                                                                                                                                                                                                            |
+|----------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| `OIDC_CLIENT_NAME`   | The name of the provider. will be displayed in the login page. Defaults to `OpenID Connect`                                                                                                                                                            |
+| `OIDC_CLIENT_ID`     | The Client ID provided by your OIDC provider.                                                                                                                                                                                                          |
+| `OIDC_CLIENT_SECRET` | The Client Secret provided by your OIDC provider.                                                                                                                                                                                                      |
+| `OIDC_SERVER_URL`    | The base URL of your OIDC provider's discovery document or authorization server (e.g., `https://your-provider.com/auth/realms/your-realm`). `django-allauth` will use this to discover the necessary endpoints (authorization, token, userinfo, etc.). |
+| `OIDC_ALLOW_SIGNUP`  | Allow the automatic creation of inexistent accounts on a successfull authentication. Defaults to `true`.                                                                                                                                               |
+
+**Callback URL (Redirect URI):**
+
+When configuring your OIDC provider, you will need to provide a callback URL (also known as a Redirect URI). For WYGIWYH, the default callback URL is:
+
+`https://your.wygiwyh.domain/auth/oidc/<OIDC_CLIENT_NAME>/login/callback/`
+
+Replace `https://your.wygiwyh.domain` with the actual URL where your WYGIWYH instance is accessible. And `<OIDC_CLIENT_NAME>` with the slugfied value set in OIDC_CLIENT_NAME or the default `openid-connect` if you haven't set this variable.
