Echo JS 0.11.0

the name is near impossible to make out at a glance
maybe add a hyphen like 'apostrophe-cms'

Updated link to point to github repo, the demo page wasn't loading correctly for me.

Would be nice to see a docker compose and/or dockerfile examples for a complete setup.  There does seem to be some configuration complexity on first glance.  Even though it's not my cup of tea, it is an interesting concept for a CMS.
