I've just pushed a big update to the documentation.
The Getting Started is (hopefully) clearer for what to do depending on where you want to run Node-RED.
The main User Guide has had a bit of a reorganisation. I've also added a Node-RED Concepts page with a lot of the common terms we use - I'm sure there are others that should be on the list, but what's there is a good start.
There is a new FAQ section where we can start to answer things that come up regularly on here.
There is a new Tutorials section which currently only has the two existing tutorial flows, but will be a space to add more things.
The navigation has been updated on each page - with a 'breadcrumb' bar across the top to help you know where you are in the docs, and the left-hand table of contents is sticky (doesn't scroll off the page) so should be easier to use.
Quite a few pages have changed url as part of this work. I think we have redirects in place for everything, so no links should be broken. But please do let us know if you find something broken.
I have also updated the Cookbook to match the new style.
This isn't the end of the updates - but the set of changes had gotten sufficiently large that I wanted to get it published sooner rather than later.
Let me know what you think!
