I was reading some of the documentation of dnf. I also built the dnf package on Fedora 29. In the process, I found (1) a spelling error (2) three error messages pointing at problems with the .rst files It wasn't too hard to figure out what the fixes should be. Since the source is on github, I could just edit the files and make a push request. These three commits were accepted a couple of days later. <https://github.com/rpm-software-management/dnf/commit/9b49b06a6db314a74e904d34d917d670db835454> <https://github.com/rpm-software-management/dnf/commit/457b5fee28a22af991ce9595042477dbe4a18562> <https://github.com/rpm-software-management/dnf/commit/1b50c40d8cff339d76d09005a94a9accec7620dc>
