Fix Markdown Preview not working in Atom

Here’s how I fixed Markdown not working.

It was a conflict with the Emmet package.
I found out that this was a conflict using cmd + . keyboard shortcut
That let me know that in the file emmet.cson there was a conflict with ctrl-shift-m that is used to merge lines.
I don’t use that in emmet so I just commented it out (placed a # at the beginning of the line)
It still didn’t work.
I shut down atom and restarted and then ctrl+shift+m showed a preview of markdown.

Start Vim-Mode in Atom in Insert Mode

I needed to look this up and just wanted to save people time if they had the same issue.

Vim-Mode in Atom by default opens files in Command mode. I like to open files in Insert mode so I can quickly start typing.

This is easily accomplished inside the vim-mode package settings.

Just check the Start In Insert Mode checkbox.
