+# Post a slack message something like the following for issue and PR actions:
+#     <$url|$title>
+#     | $repo#$num · issue opened by $user
+#
+# Configuration:
+# 1. Set `SLACK_CHANNEL`.
+# 2. Add a `SLACK_BOT_TOKEN` secret to your repo. This is the "Bot User OAuth
+#    Token" from the "OAuth & Permissions" section of your Slack App
+#    (https://api.slack.com/apps). The token must have the `chat:write`
+#    permission.
+# 3. Optionally tweak the `if:` and `on:` sections below to control which issue
+#    and PR events are skipped.
