+# SQL Modes
+
+Dolt supports a subset of [SQL modes that MySQL supports](https://dev.mysql.com/doc/refman/8.4/en/sql-mode.html).
+SQL modes are added upon request, so please [file an issue](https://github.com/dolthub/dolt/issues) if a SQL mode you need is missing.
+
+**Currently supporting 4 of 18 MySQL SQL Modes.**
