-The `interface-pubsub` contains the base implementation for a libp2p pubsub router implementation. This interface should be used to implement a pubsub router compatible with libp2p. It includes a test suite that pubsub routers should run, in order to ensure compatibility with libp2p.

-## Implementations using this interface
-
-You can check the following implementations as examples for building your own pubsub router.
-
-- [libp2p/js-libp2p-floodsub](https://github.com/libp2p/js-libp2p-floodsub)
-- [ChainSafe/js-libp2p-gossipsub](https://github.com/ChainSafe/js-libp2p-gossipsub)
-
-## Interface usage
-
-`interface-pubsub` abstracts the implementation protocol registration within `libp2p` and takes care of all the protocol connections and streams, as well as the subscription management. This way, a pubsub implementation can focus on its message routing algorithm, instead of also needing to create the setup for it.
-
-### Extend interface
-
-A pubsub router implementation should start by extending the `interface-pubsub` class and **MUST** override the `_publish` function, according to the router algorithms. This function is responsible for forwarding publish messages to other peers, as well as forwarding received messages if the router provides the `canRelayMessage` option to the base implementation.
-
-Other functions, such as `start`, `stop`, `subscribe`, `unsubscribe`, `_encodeRpc`, `_decodeRpc`, `_processRpcMessage`, `_addPeer` and `_removePeer` may be overwritten if the pubsub implementation needs to customize their logic. Implementations overriding these functions **MUST** call `super`.
-
-The `start` and `stop` functions are responsible for the registration of the pubsub protocol with libp2p. The `stop` function also guarantees that the open streams in the protocol are properly closed.
-
-The `subscribe` and `unsubscribe` functions take care of the subscription management and its inherent message propagation.
-
-When using a custom protobuf definition for message marshalling, you should override `_encodeRpc` and `_decodeRpc` to use the new protobuf instead of the default one.
-
-`_processRpcMessage` is responsible for handling messages received from other peers. This should be extended if further operations/validations are needed by the router.
-
-The `_addPeer` and `_removePeer` functions are called when new peers running the pubsub router protocol establish a connection with the peer. They are used for tracking the open streams between the peers.
-
-All the remaining functions **MUST NOT** be overwritten.
-
-### Example
-
-The following example aims to show how to create your pubsub implementation extending this base protocol. The pubsub implementation will handle the subscriptions logic.
-
-```JavaScript
-const Pubsub = require('libp2p-pubsub')
-
-class PubsubImplementation extends Pubsub {
-  constructor({ libp2p, options })
-    super({
-      debugName: 'libp2p:pubsub',
-      multicodecs: '/pubsub-implementation/1.0.0',
-      libp2p,
-      signMessages: options.signMessages,
-      strictSigning: options.strictSigning
-    })
-  }
-
-  _publish (message) {
-    // Required to be implemented by the subclass
-    // Routing logic for the message
-  }
-}
-```
-
-## API
-
-The interface aims to specify a common interface that all pubsub router implementation should follow. A pubsub router implementation should extend the [EventEmitter](https://nodejs.org/api/events.html#events_class_eventemitter). When peers receive pubsub messages, these messages will be emitted by the event emitter where the `eventName` will be the `topic` associated with the message.
-
-### Start
-
-Starts the pubsub subsystem. The protocol will be registered to `libp2p`, which will result in pubsub being notified when peers who support the protocol connect/disconnect to `libp2p`.
-
-#### `pubsub.start()`
-
-### Stop
-
-Stops the pubsub subsystem. The protocol will be unregistered from `libp2p`, which will remove all listeners for the protocol and the established connections will be closed.
-
-#### `pubsub.stop()`
-
-### Publish
-
-Publish data message to pubsub topics.
-
-#### `pubsub.publish(topic, message)`
-
-##### Parameters
-
-| Name | Type | Description |
-|------|------|-------------|
-| topic | `string` | pubsub topic |
-| message | `Uint8Array` | message to publish |
-
-##### Returns
-
-| Type | Description |
-|------|-------------|
-| `Promise<void>` | resolves once the message is published to the network |
-
-### Subscribe
-
-Subscribe to the given topic.
-
-#### `pubsub.subscribe(topic)`
-
-##### Parameters
-
-| Name | Type | Description |
-|------|------|-------------|
-| topic | `string` | pubsub topic |
-
-### Unsubscribe
