+# GitHub labels archive
+
+## Overview
+
+This directory contains one YAML file per repository containing the original
+set of GitHub labels before the
+[new ones were applied on 2019-06-04](../labels.yaml.in).
+
+## How the YAML files were created
+
+This section explains how the YAML files were created.
+
+The [`labeler`](https://github.com/tonglil/labeler) tool was used to read
+the labels and write them to a YAML file.
+
+### Install and patch the `labeler` tool
+
+This isn't ideal but our [labels database](../labels.yaml.in) mandates
+descriptions for every label. However, at the time of writing, the `labeler`
+tool does not support descriptions. But,
+[there is a PR](https://github.com/tonglil/labeler/pull/37)
+to add in description support.
+
+To enable description support:
+
+```sh
+$ go get -u github.com/tonglil/labeler
+$ cd $GOPATH/src/github.com/tonglil/labeler
+$ pr=37
+$ pr_branch="PR${pr}"
+$ git fetch origin "refs/pull/${pr}/head:{pr_branch}"
+$ git checkout "${pr_branch}"
+$ go install -v ./...
+```
+
+### Save GitHub labels for a repository
+
+Run the following for reach repository:
+
+```sh
+$ labeler scan -r ${github_repo_slug} ${output_file}
+```
+
+For example, to save the labels for the `tests` repository:
+
+```sh
+$ labeler scan -r kata-containers/tests tests.yaml
+
+```
+
