Plugins

Plugins are the bread and butter of ocr_translate.

The base project implements functionalities to handle the web server, database, translation pipelines and queues.

How and which models are used is implemented entirely in plugins.

Plugins can be installed by using the plugin collapsable menu on the extension, or by directly using the manage_plugins/ endpoint (see here).
