 ## Requirements
 
-### Suggested databases
-
-Currently, Destructr is best supported by MySQL 5.7, SQLite 3, and MariaDB >=10.2.
-
-The SQLite driver is actually very fast in benchmarks, and performs very close to the same speed as MySQL 5.7 for simple queries or small databases with object counts on the order of a few thousand.
-For efficient indexing of non-standard JSON paths or large numbers of objects, MySQL 5.7 or MariaDB >=10.2 is highly recommended.
-
-### Theoretical minimum versions
-
 This system relies **heavily** on the JSON features of the underlying database.
 This means it cannot possibly run without a database that supports JSON features.
 Exact requirements are in flux during development, but basically if a database doesn't have JSON functions it's probably impossible for Destructr to ever work with it.
 
-In practice this means Destructr will **never** be able to run properly on less than the following versions of the following popular databases:
