-- Added documentation files for readthedocs ([#134](https://github.com/mpytools/filefisher/pull/134))
-  and extended the documentation with usage ([#135](https://github.com/mpytools/filefisher/pull/135)), installation instructions ([#136](https://github.com/mpytools/filefisher/pull/136)), as well as extension of the api documentation ([#141](https://github.com/mpytools/filefisher/pull/141))
