Important Note: CRX_REQUIRED_PROOF_MISSING

See crx3 for further details. Essentially, due to tightening regulations regarding the sources of chrome extensions, most users will be unable to install extensions built with this plugin, and it will be difficult to update them. This plugin therefore is probably not suitable for public Chrome Extensions. Your best bet is probably to bundle your application via Webpack and build and distribute manually through the web store. This plugin is useful for managing enterprise plugins however, provided that you're able to enforce a managed policy.
