Plugin Manifest

The manifest file is a JSON file that describes various properties of the plugin. If you use the Yeoman generator, it should be automatically generated based on the answers you've provided. The supported properties are:

• manifest_version: For now should always be "1"
• name: Name of the plugin
• description: Additional information about the plugin
• version: Version number such as "1.0.0"
• homepage_url: Homepage URL of the plugin (can also be, for example, a link to a GitHub repository)

Here's a complete example:

{
    "manifest_version": 1,
    "name": "Joplin Simple Plugin",
    "version": "1.0.0",
    "description": "To test loading and running a plugin",
    "homepage_url": "https://joplinapp.org"
}
