I suggest adding a $ prompt character at the beginning of line 190, 202, 204, 206, 214, 233 and 255, as is done on line 242, and changing Bash to bash. While both render correctly in github, only the lowercase version renders properly in github pages.

As you pointed out in https://github.com/DavidAnson/markdownlint/blob/v0.26.2/doc/Rules.md#md014 , commands that have no output do not need to be preceeded by a prompt ($). I'm ok as is or if the prompts are removed from commands without output.
