 This package contains a pure-Python MySQL client library, based on `PEP 249`_.
 
-Most public APIs are compatible with mysqlclient and MySQLdb.
-
-NOTE: PyMySQL doesn't support low level APIs `_mysql` provides like `data_seek`,
-`store_result`, and `use_result`. You should use high level APIs defined in `PEP 249`_.
-But some APIs like `autocommit` and `ping` are supported because `PEP 249`_ doesn't cover
-their usecase.
