 On Windows,`pyenchant` may cause problems.
-I'm looking for a good alternative for spell checking.
+If no external spell checking tool is installed, novelWriter will use a basic spell checker based on standard Python package `difflib`.
+Currently, only English dictionaries are available, but more can be added to the `nw/assets/dict` folder.
+See the RADME.md file in that folder for how to generate more dictionaries.
+This option is both slow and limited.
 
 Note: On Windows, make sure Python3 is in your PATH if you want to launch novelWriter from command line.
 You can also right click the `novelWriter.py` file, create a shortcut, then right click again, select "Properties" and change the target to your python executable and `novelWriter.py`.
