-## Disabling a rule (Deprecated)
-
-_This is a soon-to-be deprecated feature. Do not use. See [migration guide](./docs/counter-migration-guide.md)_
-
-`erblint` does not natively support rule disables. At GitHub, we've implemented these rules in a way to allow rules to be disabled at an offense-level via counters or disabled at a file-level because often times, we want to enable a rule but aren't able to address all offenses at once. We achieve this in one of two ways.
-
-Rules that are marked as `Counter` can be disabled by adding a comment with the offense count that matches the number of offenses within the file like:
-
-```.html.erb
-<%# erblint:counter GitHub::Accessibility::LinkHasHrefCounter 1 %>
-```
-
-In this comment example, when a new `LinkHasHref` offense has been added, the counter will need to be bumped up to 2. More recent rules use a `Counter` format.
-
-If you are enabling a rule for the first time and your codebase has a lot of offenses, you can use the `-a` command to automatically add these counter comments in the appropriate places.
-
-```
-bundle exec erblint app/views app/components -a
-```
-
-Rules that are not marked as `Counter` like `NoRedundantImageAlt` are considered to be legacy format. We are in the process of migrating these to counters. These rules can still be disabled at the file-level by adding this comment at the top of the file:
-
-```.html.erb
-<%# erblint:disable GitHub::Accessibility::NoRedundantImageAlt %>
-```
-
-However, unlike a counter, any subsequent offenses introduced to the file will not raise.

 # Counter migration guide
 
+This is relevant for `erblint-github` versions <= 0.3.2.

 [ERBLint v0.4.0](https://github.com/Shopify/erb-lint/releases/tag/v0.4.0) introduces support for inline lint rule disables.
 
 Since an inline disable feature is now natively available, it is time to move away from the in-house (hacky) counter system we've used internally over the years and in this library. 🎉
