I went back to check to see if I could find the page on electron that I had submitted in the docs, but realized that I accidentally hadn't changed the id at the top of the page. Also saw that the sidebar positions were also out of order, so I updated them to all be alphabetical.
Lastly, Typescript setup usually is found in the installation category, so I moved it up there. There was a duplicate 'typescript.md' file in examples, so I removed that as well.
