-# sqlalchemy
+# flask-sqlalchemy
 
 In this lab we will implement SQLAlchemy in the mywits app. SQLAlchemy is an example of an ORM (Object Relational Mapper), which means we can deal with our data models & queries as python objects and attributes. Using sqlalchemy means we can abstract our code away from using sql directly, and leave sqlalchemy to do secure & efficient interactions with the database behind the scenes. 
 
-This lab comes with full and annotated example code. However you are **strongly** encouraged to try each step for yourself as much as possible before resorting to the code in the repo.
