+# Async Data Flow
+
+To avoid some performance issues, all communication with the database
+is async using the *asyncpg* module. This 
+
+# Initialization
+
+When using asyncpg, the *__init()__* method in a class cannot have any
+calls to an async routine. This is because it's a constructor. This
+then requires two steps to initialize a class. The first one
+constructs an instantiation of the class, the following line then
+calls **connect**, whichfrom then on is fully async.
+
+## Defining methods
+
+Each class must have *async* in front of the *def* if it is to call
+any async code. Since this gets messy really fast, I just make all the
+defs async to avoid confusion. For example:
+
+    async def importDB(self, table: str, ):
+
+## Calling A Method
+
+To call any async method, you need to prefix it with *await*. I think
+of it this way, *async def* puts the task on a list, and await pulls
+it out. Nice and simple. For example:
+
+	data = await self.tmdb.execute(sql)
+
+# Threading
+
+Originally this propject was using *concurrent.futures* for threading,
+but has switched entirely to the *asynio* module using asychronis
+tasks instead of threads since everything is designed to work
+together.
