• What is with metafacture/metafacture-documentation ?

The documentation guide is the central place for all Metafacture Core Documentation since the introduction of metafacture fix. The repo holds the template and content of the documentation page: https://metafacture.github.io/metafacture-documentation/

• wiki? in metafix-wiki and metafacrure-core wiki.

We migrated all info from the old wiki to there except the Developer Guidelines and the old Metafacture Morph Documentation.
