First, shut DKey, then add the words by:

• Open up explorer, go to: c:/Program files/Dkey/
• find wordlist.txt, open it (double click) - it should open in notepad
• Go to the end of the list (press ctrl+end)
• add each of the words you want, seperated by a new line
• Close the file (saving it on the way)

• Find the make_dict.exe file in the same folder (c:/Program files/Dkey/)
• Double click it - you probably wont notice it do anything!

Job done. Restart Dkey and test out the word...
