+# Examples
+
+This page provides some example configuration for different scenarios.
+
+---
+
+## Auth
+
+Examples for configuring different [Dex connectors](https://dexidp.io/docs/connectors/)
+
+### Azure
+
+For Azure, we recommend creating an [OpenID connector](https://dexidp.io/docs/connectors/oidc/).
+
+- Follow the steps to create the Azure App at [Azure Docs](https://learn.microsoft.com/en-us/power-pages/security/authentication/openid-settings#create-an-app-registration-in-azure)
+
+    - Make sure to set the RedirectURI to ```<logfire_url>/auth-api/callback```
+    - Make sure to copy the secret value when you create it
+
+- To finish the configuration on your Helm values file, you will need:
+    - Directory (Tenant) ID and     Application (client) ID, you can get both of these from the Azure App overview page
+    - The client secret value you copied on the previous step
+
+It should look something like this:
+```yaml
+    connectors:
+      - type: oidc
+        id: azuread
+        name: Microsoft
+        config:
+          issuer: https://login.microsoftonline.com/<tenant_id>/v2.0
+          clientID: <App client ID>
+          clientSecret: <Client secret value>
+          insecureSkipEmailVerified: true
+```
+
+### Github
+
+For GitHub you can use the [GitHub connector](https://dexidp.io/docs/connectors/github/)
+
+- Follow the steps for creating an OAuth app [in the GitHub docs](https://docs.github.com/en/apps/oauth-apps/building-oauth-apps/creating-an-oauth-app)
+
+    ![Github OAuth App](../../images/self-hosted/dex-github-oauth-app.png)
+
+    !!! note
+        Make sure to set the callback URL to ```<logfire_url>/auth-api/callback```
+
+    ![Github OAuth App Permissions](../../images/self-hosted/dex-github-oauth-app2.png)
+    !!! note
+        For personal apps, setting at least email read access is required here. For Organizations, this is not needed.
+
+- After creating the app, on the ```General``` tab at the left, at the Client secrets section, click ```Generate a new client secret```, and copy the value.
+
+- On your values file:
+    ```yaml
+        logfire-dex:
+        ...
+        config:
+            connectors:
+            - type: "github"
+                id: "github"
+                name: "GitHub"
+                config:
+                # You get clientID and clientSecret by creating a GitHub OAuth App
+                # See https://docs.github.com/en/apps/oauth-apps/building-oauth-apps/creating-an-oauth-app
+                clientID: client_id
+                clientSecret: client_secret
+    ```
