+## MySQL
+
+The compatibility with MySQL was tested, even so, it is advisable to observe the operation of the application with this DB, as it is a new option, recently added. If you spot any problems, feel free to submit a PR.
+
+To use MySQL as database you can provide the following environment variables:
+ - `DB_TYPE=mysqldb`
+ - `DB_MYSQLDB_DATABASE` (default: 'n8n')
+ - `DB_MYSQLDB_HOST` (default: 'localhost')
+ - `DB_MYSQLDB_PORT` (default: 3306)
+ - `DB_MYSQLDB_USER` (default: 'root')
+ - `DB_MYSQLDB_PASSWORD` (default: empty)
+
+
+```bash
+export DB_TYPE=mysqldb
+export DB_MYSQLDB_DATABASE=n8n
+export DB_MYSQLDB_HOST=mysqldb
+export DB_MYSQLDB_PORT=3306
+export DB_MYSQLDB_USER=n8n
+export DB_MYSQLDB_PASSWORD=n8n
