# Notes for Windows Users
It seems that the default python on Windows is not fully functional,
and windows might not allow executing python scripts by default. See
[issue 124](https://github.com/newren/git-filter-repo/issues/124),
[issue 36](https://github.com/newren/git-filter-repo/issues/36), and
[this git mailing list
thread](https://lore.kernel.org/git/nycvar.QRO.7.76.6.2004251610300.18039@tvgsbejvaqbjf.bet/)
for details and workarounds. I believe that Windows users installing
git-filter-repo via Scoop will be okay, but those using a manual
installation or pip install may run into these issues.

So, installation might look something like the following:
1. If you don't have the necessary documentation files (because you
are installing from a clone of filter-repo instead of from a
tarball) then you can first run:
`make snag_docs`
(which just copies the generated documentation files from the
`docs` branch)
2. Run the following
```
cp -a git-filter-repo $(git --exec-path)
cp -a git-filter-repo.1 $(git --man-path)/man1
cp -a git-filter-repo.html $(git --html-path)
ln -s $(git --exec-path)/git-filter-repo \

However, the place where pip places that package might not be in your
$PATH (thus requiring you to manually update your $PATH afterwards),
and on windows the pip install might not take care of python-specific
issues for you (see "Notes for Windows Users", above). As such,
installation via package managers is recommended instead.
