unity intellisense in visual studio code code example

Example: unity visual studio code intellisense not working

In Unity editor:
1. Go to Edit/Preferences...
2. Click on External Tools
3. Under where it says "Generate .csproj files for:", check any one of
	the boxes (I personally clicked Embedded Packages but I don't believe
    it matters)
4. Click the "Regenerate project files" button
5. Close Visual Studio Code if it wasn't already closed
6. Reopen Visual Studio Code - intellisense should now (hopefully) be working
