 To further minimize build time, tests are run only on Linux, against Java 11, and without Docker support.
 It is unusual but possible for cross-component incompatibilities to only be visible in more specialized environments (such as Windows).
 
-### Running on a limited plugin set
-
-To run on a limited plugin set, add the label `limited-plugin-set` to run PCT in a PR - You would do this when debugging pipeline changes.
-
-> [!NOTE]
-> By default the set contains 10 plugins to consume a low amount of cloud resources.
-
-If you lack triage permission and so cannot add this label, or if you want to run on your own set of plugins, then you may instead
-
-```bash
-# One per line
-echo 'jenkinsci/variant-plugin	variant' > limited-plugin-set
-git add limited-plugin-set
-git commit -m 'Run limited plugin set'
-```

-Keep the PR in draft until tests pass and this file can be deleted.

 ### Replay any specific case
 
 If you want to test specific cases without ever changing labels or marker files, you can update the `flags` map on top of the pipeline in replays.
 
-Ex, to simulate a `full-test` marker with a `weekly-test` & `limited-plugin-set` labels, update this at the top of the pipeline:
