 A LaTeX package which provides macros integrated with LuaTeX and the commandline tool `git`.
 
 ## Installation
-In order to install this package the right way, one should create the release tarball first with `make package`.
-Afterward be sure to unpack the contents of the release tarball anywhere where TeX will find it, i.e. `~/texmf`.
+The recommended way of installing is using `tlmgr install gitinfo-lua`.
+If you can't update/install packages with `tlmgr`, you can download the latest `gitinfo-lua-<version>.tds.tar.gz` from the [releases page](https://github.com/Xerdi/gitinfo-lua/releases) and then unpack it in your `TEXMFHOME`.
+To find out where your `TEXMFHOME` is, you can consult `kpsewhich --var-value TEXMFHOME` on the commandline.
 
 ## Documentation
-The documentation can be built using `make` or manually using `lualatex`:
+A prerequisite is that you have the [texmf-packaging](https://github.com/Xerdi/texmf-packaging) available in your `TEXMFHOME`.
+The documentation can be built using `make build clean` or manually using `lualatex`:
 ```bash
-make build clean
-# Or manually
+# Using the original TEXMFHOME and the project directory
+CNF_LINE="TEXMFHOME={$(pwd),$(kpsewhich --var-value TEXMFHOME)}"
 cd doc
-lualatex -shell-escape gitinfo-lua.tex
+lualatex --lua=gitinfo-lua-init.lua -bibtex -cnf-line $CNF_LINE gitinfo-lua
 makeindex -s gind.ist gitinfo-lua.idx
-lualatex -shell-escape gitinfo-lua.tex
+lualatex --lua=gitinfo-lua-init.lua -bibtex -cnf-line $CNF_LINE gitinfo-lua
 ```
+To do the same as the Lua initialization script, commandline option `--shell-restricted` should be passed and `git` should be added to `shell_escape_commands` in your `texmf.cnf`.
+The `texmf.cnf` file to edit can be found with `kpsewhich texmf.cnf`.
