• Moved screenshots in their own folder to clean root directory
• Changed urls for images in README to file references

Hi,
thanks but is not working on npm.
The readme is also available there:
https://www.npmjs.com/package/matterbridge
and there the screenshot directory doesn't exist nor the Screenshot*.jpg and Screenshot*.png.
See .npmignore

@Luligu That should fix itself when you merge this directly before the next release :-)

No cause there is not

• ./frontend/public/matterbridge 64x64.png in npm package
• ./screenshot/Screenshot home.jpg in npm package
  I make the published package as slim as possible.
  This is why the link are to GitHub.
  So if you want cleanup and move all jpg to the screenshot directory (good for me as I told you) you need to keep the link with full path to GitHub.
