If you’re using Jekyll to blog or just using Markdown files for blogging and want to ensure that you’re not making spelling errors you can do the following:

Within the Sublime Text editor, open your markdown file -> Select Preferences -> Settings - More -> Syntax Specific - User -> (This should open a file called Markdown.sublime-settings where you need to add the following)

"spell_check": true

You should now see any potential corrections in your file.
