-# Issue-Labeler Workflows
-
-This repository uses actions from [dotnet/issue-labeler](https://github.com/dotnet/issue-labeler) to predict area labels for issues and pull requests.
-
-The following workflow templates were imported and updated from [dotnet/issue-labeler/wiki/Onboarding](https://github.com/dotnet/issue-labeler/wiki/Onboarding):
-
-1. `labeler-cache-retention.yml`
-2. `labeler-predict-issues.yml`
-3. `labeler-predict-pulls.yml`
-4. `labeler-promote.yml`
-5. `labeler-train.yml`
-
-## Repository Configuration
-
-Across these workflows, the following changes were made to configure the issue labeler for this repository:
-
-1. Set `LABEL_PREFIX` to `"area-"`:
-    - `labeler-predict-issues.yml`
-    - `labeler-predict-pulls.yml`
-    - `labeler-train.yml`
-2. Set `DEFAULT_LABEL` to `"needs-area-label"`:
-    - `labeler-predict-issues.yml`
-    - `labeler-predict-pulls.yml`
-3. Remove the `EXCLUDED_AUTHORS` value as we do not bypass labeling for any authors' issues/pulls in this repository:
-    - `labeler-predict-issues.yml`
-    - `labeler-predict-pulls.yml`
-4. Update the pull request labeling branches to include `main` and `release/*`:
-    - `labeler-predict-pulls.yml`
-5. Remove the `repository` input for training the models against another repository:
-    - `labeler-train.yml`
-6. Update the cache retention cron schedule to an arbitrary time of day:
-    - `labeler-cache-retention.yml`
