 - Increment the metadata version on change, keeping to [semver](https://semver.org/) to indicate compatibility of new versions.

+### Distribution Format
+
+Modules are expected to be distributed as a compressed ZIP file, where the ZIP contents follow that of a module folder.
+BookStack provides a `php artisan bookstack:install-module` command which allows modules to be installed from these ZIP files, either from a local path or from a web URL.
+Currently, there's a hardcoded total filesize limit of 50MB for module contents installed via this method.
+
+There is not yet any direct update mechanism for modules, although this is something we may introduce in the future.
