+CrateDB is wire-protocol compatible to PostgreSQL, and you can use all of its
+features using plain SQL.
+Other than integrating well with commodity systems using standard database
+access interfaces like ODBC or JDBC, it provides a proprietary HTTP interface
+on top.
+
+You have a variety of options to connect to CrateDB, and to integrate it with
+off-the-shelve, 3rd-party, open-source, and proprietary applications.
+
+See {ref}`connect`.
