In 2019, Fink decided to participate to the LSST call for community broker. The first step was the submission of a Letter of Intent to LSST in Summer 2019 to describe the project, and our goals: Fink - a new generation of astronomy broker based on Active Learning and Apache Spark.

You can read it online. This letter is succinct, and we expect to get the Fink white paper out in the next few months. Stay tuned!
