-This is a demo XMTP v3-alpha console client (CLI) that you can use to send and receive messages via the command line. Specifically, you can use it to try out [double ratchet messaging](https://github.com/xmtp/libxmtp/blob/main/README.md#double-ratchet-messaging) and [installation key bundles](https://github.com/xmtp/libxmtp/blob/main/README.md#installation-key-bundles) enabled by XMTP v3-alpha.

 Use the CLI to send a [double ratchet message](https://github.com/xmtp/libxmtp/blob/main/README.md#double-ratchet-messaging) between test wallets on the XMTP `dev` network.
 
 1. Go to the `examples/cli` directory.
 
-2. Create a sender wallet account (user1). Create an [installation key bundle](https://github.com/xmtp/libxmtp/blob/main/README.md#installation-key-bundles) and store it in the database. Grant the installation key bundle permission to message on behalf of the sender address. This will allow the CLI to message on behalf of the sender address.
+2. Create a sender wallet account (user1). Create an [XMTP identity](../../xmtp_mls/IDENTITY.md) and store it in the database. Grant the installation key bundle permission to message on behalf of the sender address. This will allow the CLI to message on behalf of the sender address.

-5. Send a message into the conversation. The message is sent using [one session between each installation](https://github.com/xmtp/libxmtp/blob/main/README.md#installation-key-bundles) associated with the sender and recipient. The message is encrypted using a per-message encryption key derived using the [double ratchet algorithm](https://github.com/xmtp/libxmtp/blob/main/README.md#double-ratchet-messaging).
+5. Create a new group and take note of the group ID.
 
    ```bash
-   ./xli.sh --db user1.db3 send <user2_address> "hello"
+   ./xli.sh --db user1.db3 create-group
    ```
 
-6. List conversations and messages.
+6. Add user 2 to the group
 
    ```bash
-   ./xli.sh --db user1.db3 list-conversations
+   ./xli.sh --db user1.db3 add-group-member $GROUP_ID $USER_2_WALLET_ADDRESS
+   ```
+
+7. Send a message
+   ```bash
+   ./xli.sh --db user1.db3 send $GROUP_ID "hello world"
+   ```
+
+8. Have User 2 read the message
+
+   ```bash
+   ./xli.sh --db user2.db3 list-group-messages $GROUP_ID
    ```
 
 If you want to run the CLI against localhost, go to the root directory and run `dev/up` to start a local server. Then run the CLI commands using the `--local` flag.
