 # AstrAFocus
-`AstrAFocus` is a package designed to automate the autofocus (AF) process for telescopes. It comprises two main components:
+AstrAFocus is a package that provides flexible autofocus (AF) procedures for telescopes.
+The tasks that this package aims to automate fall into two broad categories.
 1. **Locate the focus calibration region**: 
    - Identify an area around the zenith that is suitable for focus calibration, given the chosen
    focus measurement operator.

 - Focsuing
   - `SweepingAutofocuser`: Performs the autofocusing using sweeping through a range of focus positions.
   - `AnalyticResponseAutofocuser(SweepingAutofocuser)`: Performs the autofocusing utilising the analytic nature of the focus response curve of a given focus measure.
+  - `NonParametricResponseAutofocuser(SweepingAutofocuser)`: Performs the autofocusing using an arbitrary focus measure operator and then applying an extremum estimator from to find the position of maximal focus.
