 To start monitoring all pipelines in a project, use the following slash command inside a channel:
 
-    ```
-    /azpipelines subscribe [project url]
-    ```
+```
+/azpipelines subscribe [project url]
+```
 
 The project URL can link to any page within your project (except URLs to pipelines). For example: */azpipelines subscribe https://dev.azure.com/myorg/myproject/*
 
 
 You can also monitor a specific pipeline using the following command:
 
-    ```
-    /azpipelines subscribe [pipeline url]
-    ```
+```
+/azpipelines subscribe [pipeline url]
+```
 
 The pipeline URL can link to any page within your pipeline that has a `definitionId` or a `buildId/releaseId` in the URL. For example: */azpipelines subscribe https://dev.azure.com/myorg/myproject/_build?definitionId=123*, or: */azpipelines subscribe https://dev.azure.com/myorg/myproject/_release?definitionId=123&view=mine&_a=releases*
