@akkspros again, thanks for these updates on comments but if you're searching for a contributor badge then picking up some defined work like #22 is more ideal. Alternate to that, trying to get Tide working locally and documenting any issues you run into would be most helpful. Making small changes to comments and docs for capitalization and small spelling errors isn't going to dramatically move Tide forward, though I do appreciate the help.
