PGF is a TeX macro package for generating graphics. It is platform-
and format-independent and works together with the most important TeX
backend drivers, including pdftex and dvips. It comes with a
user-friendly syntax layer called TikZ.
See the directory doc/generic/pgf for more information. See the file
doc/generic/pgf/pgfmanual.pdf (also available from
https://pgf-tikz.github.io/pgf/pgfmanual.pdf) for a manual. This
documentation also explains the installation. See the file
doc/generic/pgf/license/LICENSE for license details.
Please go to the official repository at https://github.com/pgf-tikz/pgf or the official mailing list at https://tug.org/mailman/listinfo/pgf-tikz to submit bug reports, request new features, etc.
We also have a chat on the Matrix network at #pgf-tikz:matrix.org (read-only version).
In general you should just use the version of PGF that is shipped by your TeX distribution. See their documentation on how to install packages.
If you are feeling adventurous you can install the latest development version in TeX Live from our tlcontrib repository.
$ tlmgr repository add http://pgf-tikz.github.io/pgf/tlnet pgf-development
$ tlmgr pinning add pgf-development "*"
$ tlmgr update --self --all
$ tlmgr install pgf --reinstallCurrently PGF only has a very rudimentary test suite to check for regressions, so for now we check for bugs by building the manual for each commit. To build the manual locally you can either copy the PGF repository into your texmf tree (not recommended) or use the usertree option of TeX Live. For the usertree option on GNU/Linux, follow these steps:
$ git clone https://github.com/pgf-tikz/pgf
$ tlmgr init-usertree --usertree pgf
$ export TEXMFHOME=$(readlink -f pgf)
$ cd pgf
$ l3build doc -q -HWe recommend building at least the version for LuaTeX, as shown in the example above because this has the broadest coverage of PGF features. To test the animations feature you have to build the version for dvisvgm.
