1. Initialize the solver by pressing the Initialize button. This causes it to precompute this large (~220 MB) array of values
2. Use "Find best" to choose a word for you or enter in your own choice of word, and press Submit word. Submit this word in Wordle as well
3. Click on the letters of the word to match the results of what was matching according to Wordle. Hit confirm when it matches the colors of the word in Wordle. This will cause the solver to eliminate words that are no longer possible. If there was an error in the color pattern you can hit Back to remove the last confirmed word, and reenter it.
4. Optimally win Wordle.
