-* [Developer update: 275% improved game compression](https://lichess.org/blog/Wqa7GiAAAOIpBLoY/developer-update-275-improved-game-compression)
+This library was migrated from the Java language to the Scala language.
+Only the language syntax changed to Scala; the design and paradigms of the Java program were kept.
+This is not how Scala code should be written, it is not idiomatic.
