documentation for doing a release manually

[basisbit]

There are various common reasons why the plugin might fail, without it giving a helpful error message or how to continue. Thus, imho it would be very helpful to add some documentation in the README.md file on what which step does and what commands are needed to manually run it. Then users can copy & pasta them into shell after resolving a merge conflict or a faulty version number update or various other things.

It doesn't make sense to add this to the readme. Goal steps depend on the configuration. It would be great to have continue feature or at least print out commands to the console in case of failure, but it is not a trivial task to do so. Ideas / PR-s are welcome.
