Add or remove the words to be transliterated by inputting their Strong's concordance value and their KJV translation(s). While there are many reference sites for searching Strong's, I like to use Biblehub. If a certain word is sometimes translated as more than one word, like H1368, make sure to add those in the second column. You do not need to add every different one-word translation for the program to work.
Use the "Upload your list" button to select your my_strongs_dict.json file. After selection, the upload will begin automatically.
Expected format: {"H7225": {"translations": ["beginning"], "color": "#ffaa00"}, ...}
