 # Take a test drive
 
-You can easily try out Netlify CMS by running it on a pre-configured starter site. Our example in the [intro](/docs/intro) is the [Kaldi small business Hugo template](https://github.com/netlify-templates/kaldi-hugo-cms-template). Use the deploy button below to build and deploy your own copy of the repository:
+Netlify CMS can run in any frontend web environment, but the quickest way to try it out is by running it on a pre-configured starter site with Netlify. Our example here is the [Kaldi coffee company template](https://github.com/netlify-templates/one-click-hugo-cms). Use the button below to build and deploy your own copy of the repository:
 
-[![Deploy to Netlify](https://www.netlify.com/img/deploy/button.svg)](https://app.netlify.com/start/deploy?repository=https://github.com/netlify-templates/kaldi-hugo-cms-template)
+[![Deploy to Netlify](https://www.netlify.com/img/deploy/button.svg)](https://app.netlify.com/start/deploy?repository=https://github.com/netlify-templates/one-click-hugo-cms&stack=cms)
 
-## Authenticate with GitHub
+After clicking that button, you’ll authenticate with GitHub and choose a repository name, then Netlify will automatically clone the template and deploy it, bringing you to the site dashboard when the build is complete. Next, you’ll need to set up Netlify's [Identity](https://www.netlify.com/docs/identity) service to authorize users to log in to the CMS.
 
-When the deploy completes, you can see your site, but in order to use the CMS, you'll need to set up authentication with GitHub.
+## Adding users
 
-First, register the site CMS as an authorized application with your GitHub account:
-
- 1. Go to your account **Settings** page on GitHub, and click **Oauth Applications** under **Developer Settings** (or use [this shortcut](https://github.com/settings/developers)).
- 2. Click **Register a new application**.
- 3. For the **Authorization callback URL**, enter `https://api.netlify.com/auth/done`. The other fields can contain anything you want.
+1. From the Netlify site dashboard, select the **Identity** tab, and you'll find that there are no users yet. By default, this site is set to accept users by invitation only, and even the site owner needs to be invited.
+2. Select **Invite users**, enter your email address, and select Send.
+3. Check your email for the invitation. It will be sent from `no-reply@netlify.com`.

-When you complete the registration, you'll be given a **Client ID** and a **Client Secret** for the app. You'll need to add these to your Netlify project:
-
- 1. Go to your [**Netlify dashboard**](https://app.netlify.com/) and click on your project.
- 2. Click the **Settings** tab.
- 3. Click on the **Access control** tab, then scroll down to **OAuth**.
- 4. Under **Authentication providers**, click **Install Provider**.
- 5. Select GitHub and enter the **Client ID** and **Client Secret**, then save.
+4. Click the link to accept the invite, and you’ll be directed to your new site, with a prompt to create a password.
 
-## Access the CMS

-With the site deployed and authentication in place, you'll be able to enter the CMS by going to the URL of your new site and appending `/admin`.
+5. Enter a password, sign in, and you’ll be directed straight to the CMS!
+
+Try adding and editing posts, or changing the content of the Products page. When you save, the changes will be pushed immediately to GitHub, triggering a build on Netlify, and updating the content on your site.
