Spacemacs badge usage

[nashamri]

After many trials and errors, I think this is the best way to display the badge and use it.
I couldn't get the SVG to show up with relative paths so I had to hardcode it 😄

👍 I also don't know any other way to display svg here.

It seems to be a known issue isaacs/github#316

[CestDiego]

Finally it seems you figured it out! :D I'm happy and I'm using it already https://github.com/CestDiego/sweetgreen.el

@nashamri I think it'd be better to have ![https://github.com/syl20bnr/spacemacs](cdn....) so that people can click on it and go to spacemacs page :P

[nashamri]

@CestDiego oh good catch!

[CestDiego]

@nashamri also..don't forget to give instructions on how to use it in Org-Mode:

Done! Thanks @CestDiego!

Let's cut down the wording -- it's a tad too wordy.

In addition, syntax is wrong, here's the correct version:
