 This is a first rudimentary version, but sufficient for now. The PDF has an index with clickable links and each song starts on a new page.
 
+## Prerequisites
+
+- `xelatex` should be installed (see [XeTeX's Wikipedia page](https://en.wikipedia.org/wiki/XeTeX) for more info)
+- Script needs read/write permission in the current folder
+- Files in the target directory are stored as `.txt` files
+- Tested and developed on OSX, but should be possible to make it work on other platforms without much effort.
+
 ## How to generate your PDF?
-- Configure the path to your txt files in generate.sh
-- Run songbook.tex from terminal with write18 enabled, to be able to execute shell scripts: `$ xelatex -enable-write18 songbook.tex`
+
+Run the following command from the directory containing this repo code:
+
+```Shell
+$ bash ./songbook.sh /path/to/tab/directory
+```
+
+This will create a file named `songbook.pdf` containing all the `.txt` files from the provided directory.
