- Open a Help file in the menu ▸ or by using function from a file manager (for example in KDE, right-click on the file and select in popup menu ▸ ).
- For the reason that files may be very big and have a large number of xml-tags, you can use the find by file (usually ▸ or Ctrl+F).
- Make the necessary changes (if you are not confident with xml-tags of help files, make sure you have not touched them).
- Save the file.
