More README.md files updated

Some of the files modified include some of the files modified yesterday;
others were not modified yesterday. I backtracked as I noticed some
sections are missing in earlier README.md files. However more have to be
checked in earlier years. I'm committing now as I have to do other
things and am likely done for the day.
