+# Publish revisions with GitHub Actions in Azure Container Apps Preview
+
+Azure Container Apps allows you to use GitHub Actions to publish [revisions](revisions.md) to your container app. As commits are pushed to your GitHub repository, a GitHub Action is triggered which updates the [container](containers.md) image in the container registry. Once the container is updated in the registry, Azure Container Apps creates a new revision based on the updated container image.
+

+
+The GitHub action is triggered by commits to a specific branch in your repository. When creating the integration link, you decide which branch triggers the action.
+
+## Authentication
+
+When adding or removing a GitHub Actions integration, you can authenticate by either passing in GitHub [personal access token](https://docs.github.com/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token), or using the interactive GitHub login experience. The interactive experience opens a form in your web browser and gives you the opportunity to log in to GitHub. Once successfully authenticated, then a token is passed back to the CLI that is used by GitHub for the rest of current session.
+
+- To pass a personal access token, use the `--token` parameter and provide a token value.
+- If you choose to use interactive login, use the `--login-with-github` parameter with no value.
+
+## Add
+
+The `containerapp github-action add` command creates a GitHub Actions integration with your container app.
+
+The first time you attach GitHub Actions to your container app, you need to provide a service principal context. The following command shows you how to create a service principal.
+
+# [Bash](#tab/bash)
+
+```azurecli
+az ad sp create-for-rbac \
+  --name <SERVICE_PRINCIPAL_NAME> \
+  --role "contributor" \
+  --scopes "/subscriptions/<SUBSCRIPTION_ID>/resourceGroups/<RESOURCE_GROUP_NAME>" \
+  --sdk-auth
+```
+
+# [PowerShell](#tab/powershell)
+
+```azurecli
+az ad sp create-for-rbac `
+  --name <SERVICE_PRINCIPAL_NAME> `
+  --role "contributor" `
+  --scopes "/subscriptions/<SUBSCRIPTION_ID>/resourceGroups/<RESOURCE_GROUP_NAME>" \
+  --sdk-auth
+```
+
+---
+
+The return value from this command is a JSON payload, which includes the service principal's `tenantId`, `cliendId`, and `clientSecret`.
+
+The following example shows you how to add an integration while using a personal access token.
+
+# [Bash](#tab/bash)
+
+```azurecli
+az containerapp github-action add \
+  --repo-url "https://github.com/<OWNER>/<REPOSITORY_NAME>" \
+  --docker-file-path "./dockerfile" \
+  --branch <BRANCH_NAME> \
+  --registry-url <URL_TO_CONTAINER_REGISTRY> \
+  --registry-user-name <REGISTRY_USER_NAME> \
+  --registry-password <REGISTRY_PASSWORD> \
+  --service-principal-client-id <CLIENT_ID> \
+  --service-principal-client-secret <CLIENT_SECRET> \
+  --service-principal-tenant-id <TENANT_ID> \
+  --token <YOUR_GITHUB_PERSONAL_ACCESS_TOKEN>
+```
+
+# [PowerShell](#tab/powershell)
+
+```azurecli
+az containerapp github-action add `
+  --repo-url "https://github.com/<OWNER>/<REPOSITORY_NAME>" `
+  --docker-file-path "./dockerfile" `
+  --branch <BRANCH_NAME> `
+  --registry-url <URL_TO_CONTAINER_REGISTRY> `
+  --registry-user-name <REGISTRY_USER_NAME> `
+  --registry-password <REGISTRY_PASSWORD> `
+  --service-principal-client-id <CLIENT_ID> `
+  --service-principal-client-secret <CLIENT_SECRET> `
+  --service-principal-tenant-id <TENANT_ID> `
+  --token <YOUR_GITHUB_PERSONAL_ACCESS_TOKEN>
+```

+As you interact with this example, replace the placeholders surrounded by `<>` with your values.
+
+## Show
+
+The `containerapp github-action show` command returns the  GitHub Actions configuration settings for a container app.
+
+This example shows how to add an integration while using the personal access token.
+
+# [Bash](#tab/bash)
+
+```azurecli
+az containerapp github-action show \
+  --resource-group <RESOURCE_GROUP_NAME> \
+  --name <CONTAINER_APP_NAME>
+```
+
+# [PowerShell](#tab/powershell)
+
+```azurecli
+az containerapp github-action show `
+  --resource-group <RESOURCE_GROUP_NAME> `
+  --name <CONTAINER_APP_NAME>
+```
+
+---
+
+As you interact with this example, replace the placeholders surrounded by `<>` with your values.
+
+This command returns a JSON payload with the GitHub Actions integration configuration settings.
+
+## Delete
+
+The `containerapp github-action remove` command removes the GitHub Actions from the container app.
+
+# [Bash](#tab/bash)
+
+```azurecli
+az containerapp github-action remove \
+  --resource-group <RESOURCE_GROUP_NAME> \
+  --name <CONTAINER_APP_NAME> \
+  --token <YOUR_GITHUB_PERSONAL_ACCESS_TOKEN>
+```
+
+# [PowerShell](#tab/powershell)
+
+```azurecli
+az containerapp github-action remove `
+  --resource-group <RESOURCE_GROUP_NAME> `
+  --name <CONTAINER_APP_NAME> `
+  --token <YOUR_GITHUB_PERSONAL_ACCESS_TOKEN>
+```
