- Deprecates the usage of `publish_to_database` as well

 The approach is largely up to the PM and engineer creating the implementation.
 No recommendations are provided here at this time.
 
-### Record experiment subjects
-
-Snowplow tracking of identifiable users or groups is prohibited, but you can still
-determine if an experiment is successful or not. We're allowed to record the ID of
-a namespace, project or user in our database. Therefore, we can tell the experiment
-to record their ID together with the assigned experiment variant in the
-`experiment_subjects` database table for later analysis.
-
-For the recording to work, the experiment's context must include a `namespace`,
-`group`, `project`, `user`, or `actor`.
-
-To record the experiment subject when you first assign a variant, call `record!` in
-the experiment's block:
-
-```ruby
-experiment(:pill_color, actor: current_user) do |e|
-  e.record!
-end
-```

 This gem provides some RSpec helpers and custom matchers. These are in flux as of GitLab 13.10.
