@zsid : you should be able to run a local docs live preview server - see the instructions in $REPO/website/README.md .

Now that the PR has been pushed up, you can also view the Netlify preview build at https://deploy-preview-1068--react-redux-docs.netlify.com/ .

If the conflicts in this PR are fixed, could this be merged soon? I was trying to find info in the docs about using selectors to send to a colleague, but most of the info that's applicable is in this PR.

@JoshAddington : I think I had reservations on how the wording on this turned out, but it's been long enough I don't remember the specifics.

Overall, this is based off my post at https://blog.isquaredsoftware.com/2017/12/idiomatic-redux-using-reselect-selectors/ - you might want to use that as the baseline reference atm.

I'll see if I can swing back around and re-evaluate this PR soon, but my attention is mostly focused on React-Redux v7 atm.

I'm going to close this. It's not bad, but things somehow got rephrased from my original post in ways that feel a bit off to me.

In addition, we need to rethink our docs on this based on how we're working on the hooks APIs.
