 ## Getting Started
 
-{% include content/connection-modes.md %}
 
 1. From the Segment web app, click **Catalog**.
 2. Search for "Google Tag Manager" in the Catalog, select it, and choose which of your sources to connect the destination to.
 3. In your Segment UI's destination settings, enter your Container ID (note: it should start with "GTM-"). You can find this in the Admin section of your [GTM dashboard](https://tagmanager.google.com/#/admin/).
-4. GTM will be loaded on any pages where your Segment snippet is initialized and `analytics.page` gets called in client-side Javascript. Once you've turned on GTM through Segment, you can use Segment `track` events to populate the GTM `dataLayer`.

 **Notes**
-* We recommend loading GTM through Segment rather than loading Segment inside of GTM.

 * Be sure to "publish" your GTM container in GTM before trying to load it through Segment, otherwise your container URL will return a 404 error.
 
 
 ## Page
 If you're not familiar with the Segment Specs, take a look to understand what the [Page method](/docs/connections/spec/page/) does. An example call would look like:
 
 ```js
-analytics.page('Home', {
+analytics.page('Home', { 
   title: 'Welcome | My Website',
   url: 'https://mywebsite.com/'
 });
 ```
 
-You must call the Page method for Google Tag Manager to load. We already include a call to `analytics.page` in your default Segment snippet, so if you haven't removed that, GTM will work the same as if you installed the GTM snippet directly.

 ### Tracking All Pages
-When you turn on the setting to **Track All Pages** in your Optional Settings, we will track events whenever you call our `page` method and send a "Loaded A Page" event to Google Tag Manager. See the `track` section below for more info on how we send events to GTM.

 ### Named Page Events
-If you include a `name` parameter in your `page` calls and turn on the setting to **Track Named Pages** in your Optional Settings, we will also pass on an event to GTM for that page. For example, `analytics.page('Signup')` would translate to a "Viewed Signup Page" event. See the `track` section below for more info on how we send events to GTM.

 ### Environments
 If you're using an 'environment' variable for `gtm_preview` in your tag's query string, you can set that string in the **Environment** of your Optional Settings. IMPORTANT: Make sure the string includes the `gtm_auth` variable. For example, your string should look like: `env-xxxxx&gtm_auth=xxxxx`.
