-## Correct baselined warnings
-
-In addition to active warning that appear in the [python - aggregate-reports][aggregate_reports] pipeline ouput, there
-are also CredScan warnings that have been suppressed in [eng/python.gdnbaselines][baseline]. This file is a snapshot of
-the active warnings at one point in time; CredScan won't re-raise warnings that have been recorded here.
-
-Ultimately, we hope to remove this baseline file from the repository entirely. If you see any warnings for a package
-that you own in this file, please remove a few at a time from the file so that CredScan will output these warnings in
-the pipeline. Then, resolve them following the steps from the [Correct active warnings](#correct-active-warnings)
-section of this guide.
