PaperPaw is a beta: for testing, and for developers, who can build their own plugins before the release. Expect rough edges.

Community plugins

Made by others and published from GitHub. Nobody has reviewed them: the site only checks that each is a working plugin, signed by its author.

Not reviewed. A plugin with code gets full access to your reader. Install one only if you trust who made it.

Publish one

Put the plugin in a public repository on GitHub and give it the topic paperpaw-plugin.
Make a release tagged with the version, as v1.0.0, with the folder as a ZIP and, for a plugin with code, a signed build for each reader. The template does it for you.
Within the hour the site finds it, checks it and lists it here. Its first version settles the key; a later one signed by another is refused. How to publish from GitHub
