-# What is a "CODEOWNER"?
-#
-# A CODEOWNER lends their expertise to a specific package hosted by an OpenTelemetry repository.
-#
-# A CODEOWNER MUST:
-# - introduce themselves on the CNCF OTel Python channel: https://cloud-native.slack.com/archives/C01PD4HUVBL
-# - have enough knowledge of the corresponding instrumented library
-# - respond to issues
-# - fix failing unit tests or any other blockers to the CI/CD workflow
-# - update usage of `opentelemetry-python-core` APIs upon the introduction of breaking changes
-# - be a member of the OpenTelemetry community so that the `component-owners.yml` action to automatically assign CODEOWNERS to PRs works correctly.

+### How to Get PRs Reviewed
+
+The maintainers and approvers of this repo are not experts in every instrumentation there is here.
+In fact each one of us knows enough about them to only review a few. Unfortunately it can be hard
+to find enough experts in every instrumentation to quickly review every instrumentation PR. The
+instrumentation experts are listed in `.github/component_owners.yml` with their corresponding files
+or directories that they own. The owners listed there will be notified when PRs that modify their
+files are opened.
+
+If you are not getting reviews, please contact the respective owners directly.
