 What & Why
 ==========
 
-**What:** Caching library for asynchronous Python applications.
+**What:** Caching library for asyncio Python applications.
 
 **Why:** Python deserves library that works in async world

-*memoize* has you covered as you can use it with both.
-**This may come handy if you are planning a migration from Tornado to asyncio.**
-
-Under the hood *memoize* detects if you are using *Tornado* or *asyncio*
-(by checking if *Tornado* is installed and available to import).
-
-If have *Tornado* installed but your application uses *asyncio* IO-loop,
-set ``MEMOIZE_FORCE_ASYNCIO=1`` environment variable to force using *asyncio* and ignore *Tornado* instalation.
