Also includes a fix for GcUnsafe2 warnings with chronos.

 Add the following to its .nimble file:
 
 ```nim
-requires "asynctest >= 0.1.0 & < 0.2.0"
+requires "asynctest >= 0.2.0 & < 0.3.0"
 ```
 
 Usage
 -----
 
-Simply replace `test` with `asynctest` when you need to await asynchronous calls
-in the test. The same holds for `asyncsetup` and `asyncteardown`, which allow
-you to await asynchronous calls during test setup and teardown.
+Simply replace `import unittest` with `import asynctest`, and you can await
+asynchronous calls in tests, setup and teardown.
 
 Example
 -------
 
 ```nim
 
-import unittest
 import asynctest
 import asyncdispatch # alternatively: import chronos
