Not all documentation source files available in repo.
For examples when trying to access source for https://juliaplots.org/PlotlyJS.jl/stable/styles/ on Github via link "Edit on GitHub" I get 404 page: https://github.com/JuliaPlots/PlotlyJS.jl/blob/master/docs/src/styles.md

The list of pages which are not available in repo:

• Getting started / Series Types
• Ecosystem / (all subsections except Overview)
