Design Doc Section: https://docs.google.com/document/d/197fXHLlHM_RJA4-3MITwdu0N5e0HX5Q74sA4W80YMD8/edit#bookmark=id.wectpruo06vv

Update ExpensifyHelp

We also need to update the styles on the ExpensifyHelp site. All of the code for this site is in the App/docs/ directory. It has its own style sheets in App/docs/_sass/, which need to be replaced. We can’t use the same styles that we use in the App because ExpensifyHelp is not made with React Native. It’s just a web page, so we opted to use vanilla JS. This means that the scss files for ExpensifyHelp use actual css syntax, where the styles.js file used in App uses json.

Also might need to update App/docs/assets/images with the new image assets 🙂

workin on this one this week. PR is pretty much there, just held on some font PRs.

[Luke9389]

Still prioritizing the other PRs over this one right now.

Going to be working on this one today. It looks like there's an unresolved issue with the new fonts on android, so it's possible the same fix will need to be applied here once it's found.

Finally resolved the jekyll error I was experiencing. I'll commit the fix w this PR.

P.S. Is everyone reading this sure this is really a near-term priority? Be brave: if you disagree, go ahead and close it out. If someone disagrees, they'll reopen it, and if they don't: one less thing to do!
