+# Condensed Lichess Database
+This dataset is a condensed version of the Lichess database.
+It only includes games for which SF16 evaluations were available, and it does not include game headers.
+The resulting files are much smaller and faster to parse.

+# WIP
+Note, the dataset is not complete yet and subject to change.
