+		<h5>User Permission</h5>
+		<p>
+			The database user should only be granted SELECT permissions on the specified database & tables you want to query.
+			Grafana does not validate that queries are safe so queries can contain any SQL statement. For example, statements
+			like <code>USE otherdb;</code> and <code>DROP TABLE user;</code> would be executed. To protect against this we
+			<strong>Highly</strong> recommmend you create a specific MySQL user with restricted permissions.
