Getting Started
OHMG is open source software that can be self-hosted for your own georeferencing projects. This page has an overview of the platform architecture, as well as the working installation guide. This is still a work-in-progress! You can follow development, or file bugs/requests at github.com/ohmg-dev/OldInsuranceMaps.

Please understand this software is in a pre-beta state, so both the installation process and the platform itself still have rough edges.
