+# velping
+a pinger. it pings. this is made specifically for my needs, so you can open an issue for a feature request, but i likely won't accept it unless it's something i want.
+
+## configuration options
+### frontend
+- `name`: what will show as the header on the landing page.
+- `port`: what port the frontend will run on.
+- `pings`: how many pings to show on the frontend
+
+### pinging
+- `allow_empty_responses`: this does NOT mean HTTP 204, but rather if the connection being suddenly closed after a request should be accepted as online. this option only exists because i run a minecraft server.
+- `seconds_between_ping`: how often services should be pinged, in seconds.
+
+### ntfy
+- `enabled`: whether or not to enable ntfy.
+- `server`: the server to send notifications to.
+- `topic`: the ntfy topic.
+
+### services
+you can add services here, with the name of the key being the name of the service and the value being the URL to ping.
