-# Tracker
-
-Trackers are run by the community. They allow nodes to dynamically discover
-swarms by querying the tracker for info.
-
-Imagine you are in a channel on the chat. The chat may group media for that day
-in a single swarm which is accessed by nodes in that channel. To access the
-media, nodes will query the tracker, and then be able to spawn a unique `P2P`
-instance.
-
-Resource -> tracker -> P2P instance
-
-## Creating a Network
-
-Networks are spawned on the tracker in a lazy way. That is quering the tracker
-will automatically spawn a network if not already available.
-
-## Dropping Networks
-
-Networks are auto-pruned when they become stale. Assume 1 week without updates
-although this can be configured.
-
-## Query Tracker
-
-We have an identifier string, like `/darkirc/dev/1134/media`. Here `1134` refers
-to the ID of the event graph instance.
-
-Before creating the `P2P` instance, we must get the `Settings` struct.
-We then query the tracker like this:
-
-1. Send the tracker our external IP, and a port we listen on (optional - this is
-   for inbound nodes only) together with the identifier.
-2. If the tracker has no existing info for that identifier, then it will create
-   a new table.
-3. Add our node info to the table.
-4. The tracker returns a list of nodes back to us.
-
-This impl replaces the PeerDiscovery mechanism inside OutboundSession.
-
-```
-trackers = [
-    # list of trackers to query for resources ...
-]
-```
-
-## Role of Seeds
-
-Seeds may continued to be used in place of trackers such as the main DarkIRC
-event graph or darkfid where the networks are statically instanced.
-
-For dynamic instance (swarming), we may eventually replace trackers with a swarm
-network. Seed nodes will then be used to discover the swarm network.
-Trackers allow p2p net discovery to be dynamic.
