 This pdf manual and accompanying web version have been generated using the `doxygen` software (http://www.doxygen.org). This software directly reads the code and extracts the necessary comments to form the manual, meaning it is very easy to generate newer versions of the manual as desired.
 
-To maintain the usefulness of the manual, a new version should be generated after any major upgrade to `CLASS`. To keep track of how up-to-date the manual is the title page also displays the last modification date.

+You should now be able to find the finished pdf in `class/doc/manual/CLASS_MANUAL.pdf`. Finally you can commit the changes to git, but not all the content of `doc/` is necessary: only `doc/README`, `doc/input/`, `doc/manual/CLASS_MANUAL.pdf`, `doc/manual/html/`. This means that before committing you will have to do a: `git add doc/manual/html/`, but NOT a: `git add doc/manual/latex/`!
 
 As a final comment, doxygen uses two main configuration files: `doxyconf` and `doxygen.sty`, both located in class/doc/input. Changes to these files can dramatically impact the outcome, so any modifications to these files should be done with great care.
