Create-react-app: Add generated code explanation to template README

[eanplatter]

Currently the README found in the template directory (https://github.com/facebookincubator/create-react-app/blob/master/template/README.md) explains the basic scripts for getting the app up and running, but it would also be nice for it to explain the generated code so that a user can easily get a grasp on the code in their app.

I’ll probably work on this now because we plan to release tomorrow.

Sounds good! I ran out of time, hence the issue :)

[gaearon]

No worries :-) Thanks for your help.

Okay, I added some info: https://github.com/facebookincubator/create-react-app/blob/master/template/README.md.

More ideas welcome.

👍 I'll comb through it see if I have any feedback!

Looks good! Found a typo but it looks like you fixed it before I could mention it. :P

It seems pretty good, a lot of good information and I especially like linking to blog articles, very nice.

I’ll close because we can always incrementally improve.
