friendica-addons-sekb/pumpio/README.md

To let the connector work properly you should define an application name in config/addon.config.php:

'pumpio' => [
	'application_name' => '',
	// Displays forwarded posts like "wall-to-wall" posts.
	'wall-to-wall_share' => false,
	// Given in minutes
	'poll_interval' => 5,
],

This name appears at pump.io and is important for not mirroring back posts that came from Friendica.
