Reformatted README.md similar to gatsby-starter-default

[tyj144]

Hi,

I formatted the README to be similar to gatsby-starter-default after talking to Shannon Soper earlier in September.

When I first used gatsby-starter-blog, I had to do the tutorial and figure out a lot of the structure myself to get things the way I wanted, so she suggested I work on something like this. I would have liked to reformat it/clean it up bit more, but I've been sitting on it for a while without working on it, so I wanted to share my work and see if anyone else would want to continue working on it.

Hi there!
I personally quite like where this post is going... I personally recommend adapting this tutorial for the use on the docs, specifically https://www.gatsbyjs.org/docs/building-a-blog/ and submitting a pull request on the main gatsbyjs repo. Make sure to read the styling guidelines to make sure your PR is formatted correctly and is up to scratch to be merged!

Feel free to keep this PR open too...

Anush :-)

Hey @tyj144

Thank you for opening this. We've moved our official starters over to our monorepo to help ease maintenance (gatsbyjs/gatsby#10310). Closing this since this repo is now a read-only mirror.

Please reopen this PR against the monorepo if you'd like.
