 ### File Matching
 
 Most managers have a default `fileMatch` array.
-`fileMatch` is an array of Regular Expression strings used to match against the repository file list.
+The `fileMatch` array contains regular expression strings that match against the repository file list.
 
 #### Managers with no default fileMatch
 
-Some managers have no default `fileMatch`, because they have no file naming convention that would let Renovate intelligently filter them.
-In such a case, the manager will be effectively disabled until you configure a `fileMatch` value, e.g. like the following:

 #### Ignoring files that match the default fileMatch
 
-Note: Renovate will _extend_ the existing `fileMatch`, meaning you don't need to include the default values like `Dockerfile` in your own array.
-In other words, the values are "additive". If a manager matches a file that you _don't_ want it to, ignore it using the `ignorePaths` configuration option.
-Also, if you ever find that Renovate is _not_ matching a file name that you're certain it should, be sure to check that you your preset config isn't the cause of it.

 ### Enabling and Disabling Managers
 
 #### Enabling experimental managers
 
-Most managers are enabled by default. For those that aren't - typically because they are considered experimental - you can opt-in to them like the following:
