(note: you have to add 1... as the bit range values are 0-2047, but the wordlist as shown on github is indexed from 1-2048)
be careful that you have to add that 1 only if you are choosing the words manually by looking at that list, as in (1207=1208
th word).
but you never do that since you would be using a programming language and these words are placed in an array and AFAIK in all language arrays start from index 0. so in your array the word at index 1207 is the same as 1208
th word in that list.
