+Database Lab Engine (DLE) is an open-source (AGPLv3) technology that allows blazing-fast cloning of Postgres databases of any size in seconds. This helps solve many problems such as:
+- build dev/QA/staging environments involving full-size production-like databases,
 - provide temporary full-size database clones for SQL query analysis optimization (see [Joe bot](https://gitlab.com/postgres-ai/joe)),
-- automatically verify database migrations (DB schema changes) and massive data operations to avoid downtime and performance bottlenecks.
