+# Intermittent Failure Tracker service
+
+This service runs a flask server that serves two purposes:
+
+1. an API endpoint for Servo's CI builders to report
+instances of intermittent failures that are encountered
+
+2. an HTML frontend to explore trends in
+intermittent failures that have been reported.
+
+See the project's [README](https://github.com/servo/intermittent-failure-tracker/blob/master/README.md) for more details about interacting with the service,
+and [this Servo pull request](https://github.com/servo/servo/pull/16946)
+for more details about how failures are reported.
