> Right now we have discussions of installation in two places: the readme and a vignette that is (almost exclusively) focused on Linux. Both of these cover installation as a user and installation as a developer.
> We want to change this to have a better split so that we can focus the topics to what people actually need:
> * The readme should have user-facing how-to-install from CRAN + how to get nightlies and a link to a developer docs vignette if one wants to build from source / develop
> * The developer docs vignette should include details about compilation, debugging, etc.
> The developer docs should:
> [ ] Note how to install the R dependencies for the package. The audience here is not necessarily R developers, so we should be super explicit and not assume things like "I have set a CRAN mirror, of course"
> [ ] Recommend building + installing libarrow to the same / a similar non-system directory as the python docs do. (Note: this might take some testing + work to ensure that when R builds it does not attempt to link against existing system installs — I've had this happen in the past and it can be incredibly confusing when it does)
> [ ] Include debugging instructions for "Can't load this symbol" "Can't find this function" type errors (either the library isn't linking at runtime at all, or it's linking to a stale libarrow and libarrow needs to be rebuilt.
> [ ] discuss nightly builds and how to get them / when one won't be able to get them depending on the method of install
