 This package is not and is not planned to be available via `Pkg.add` as it is based on the worst and must unusable version control system ever invented: Git.
 
-## Iterative algorithms example
+## Iterative algorithms in a functional fashion
+
+The package includes `simple_iterate` which helps separating the computational step of iterative algorithms from visualisation and other reporting routines.
+It is merely intended to serve as a template, as different applications require different visualisation routines to be implemented in a replacement of `simple_iterate`; in particular [ImageTools][] implements its own version.
 
-The package includes `simple_iterate` which helps separating the computational step of iterative algorithms for visualisation routines. It is merely intended to serve as a template, as different applications require different visualisation routines to be implemented in a replacement of `simple_iterate`.  The computational step is implemented as a `do`-block anonymous function that gets passed another function is a parameter for doing the verbosity on request. Example:
+The approach is heavily indebted to functional programming.
+The computational step is to be implemented as a `do`-block anonymous function.
+That function gets passed another function `verbose` as a parameter.
+To (potentially) report the current status, the computational step only needs to call `verbose` with yet another function as a parameter. Whether the status is actually reported—and whether it needs to be calculated—is decided by `verbose`, and its parameter called as needed.
+
+### Simple example
 
 ```julia
