Update README for instructions on fixing the error.

[maning]

We describe the error but we don't say anything about how to fix them. Lets extend the READMEs for a section on how errors should be fixed. I did a short instruction for unconnectedHighways.

@Rub21 let's review all READMEs and a section on fixing the error. Add a checkmark once done.

@maning I think we just need to link the master tickets of each task instead of describing twice. @Rub21

[geohacker]

@maning this is a great idea. If we can add it hear, then for each to-fix task we can supply the instructions as a link.

@Rub21 who can take this on?

[Rub21]
