How I ran jQuery in Chrome dev tools

Today I wanted to run some jQuery code in the snippets window of the Developer Tools in Chrome.  I tried a few different things with adding a script tag and it didn't really work out for me.  So I went to the latest jQuery CDN page, opened the min source code in a new tab. Copy paste that code and create a new Snippet.  Place the code in there and run it.  Then you have jQuery.  I have it saved off and then just update the file when jQuery updates.
