 To check if a Devnet instance is alive, send an HTTP request `GET /is_alive`. If alive, the Devnet will reply with a `200 OK` and an appropriate message.
 
+### WebSocket
+
+JSON-RPC websocket methods can be accessed via the WebSocket protocol. Devnet is listening for new WebSocket connections at `ws://<HOST>:<PORT>/ws` (notice the protocol scheme). Any request body you would send to `/rpc` you can send as a text (or binary) message via WebSocket. E.g. using [`wscat`](https://www.npmjs.com/package/wscat) on the same computer where Devnet is spawned at default host and port:
+
+```
+$ wscat -c ws://127.0.0.1:5050/ws
+Connected (press CTRL+C to quit)
+> { "jsonrpc": "2.0", "id": 0, "method": "starknet_subscribeNewHeads" }
+< {"id":0,"result":2935616350010920547,"jsonrpc":"2.0"}
+```
+
 ## Interacting with Devnet in JavaScript and TypeScript
 
 To spawn Devnet and interact with it using the [Devnet API](#devnet-api), you can use [`starknet-devnet-js`](https://github.com/0xSpaceShard/starknet-devnet-js/). This can be especially useful in achieving [L1-L2 communication](./postman.md#l1-l2-interaction-via-postman).

+### Websocket subscription notifications

+On block abortion, a `starknet_subscriptionReorg` notification will be sent to all websocket subscribers requiring so according to [JSON-RPC websocket API specification](https://github.com/starkware-libs/starknet-specs/blob/v0.8.0-rc1/api/starknet_ws_api.json#L256). The `starting_block` of the orphaned chain is the successor of the new latest block and the `ending_block` of the orphaned chain is the block that was latest before aborting. One reorg notification is sent per subscription, not per websocket, meaning that if a websocket has n subscriptions, it will receive n reorg notifications, each with its own subscription ID.
+
+If a socket has subscribed to transaction status changes of a transaction `tx1` using `starknet_subscribeTransactionStatus` and the block holding `tx1` gets aborted, a `starknet_subscriptionTransactionStatus` notification shall NOT be sent. The socket shall have to rely on handling `starknet_subscriptionReorg`.

All of the deployed contracts (including predeployed), blocks and storage updates will be restarted to the original state, without the transactions and requests that may have been loaded from a dump file on startup.
