Pyblish Lite currently lacks some of the features available in Pyblish QML, so I'd also recommend you take a look at that.
Installation instructions have gotten a bit refined this week, here's the gist of it.
git clone https://github.com/pyblish/pyblish-qml
python -m pyblish_qml --debug
You can use this install with Maya and other hosts like you can with Pyblish Lite, the Python 3 process acts as a server/client architecture, running indepdently in the background serving multiple sessions of Maya, Nuke etc.
--debug will, as with Pyblish Lite, present you with a few mock items to play around with and get a feel for the GUI.
Some things to notice, the
> icon to the side of items are upcoming in Pyblish Lite as well and is used to closer inspect an item, such as messages relative a particular plug-in or instance. And the sorting is more clear, with section labels above critical sections of the main overview.
