 ## Flag Support
 
-``FlagEnum`` types are also seamlessly supported! This allows a database column to behave like a bit mask and is an alternative to multiple boolean columns. There are mostly positive performance implications for using a bit mask instead of booleans depending on the size of the bit mask and the types of queries you will run against it. For bit masks more than a few bits long the size reduction both speeds up queries and reduces the required storage space. See the documentation for [discussion and benchmarks]().
