-TellMe is a server and client application written in Python that will notify you of an event.
+A server and client notifications system written in Python that alerts you of events via SimpleX chat.
-TellMe 2.0 has been rewritten with a built-in server (over OpsDroid or Home Assistant) that talks to SimpleX chat over websockets.
 
-It is created by Taurix IT (https://www.taurix.net) and licensed under the AGPLv3 or later.
+## Overview
+
+TellMe monitors for events (completed processes, server uptime, etc.) and sends notifications through a built-in server to SimpleX chat over websockets.
+
+## Client Features
+
+- **Send messages**: `-m "Your message"` - Send custom notifications
+- **Monitor processes**: `-p <pid>` - Wait for a process to exit, then notify
+- **Watch commands**: `-w "command"` - Run a command periodically and notify on output
+- **Ping hosts**: `-P <host>` - Monitor host availability until it's reachable
+
+## Setup
+
+1. Configure the client in `~/.config/tellme/config.json`:
+```json
+{
+  "url": "http://your-server:8000",
+  "webhook": "your-webhook-name"
+}
+```
+
+2. Run the SimpleX CLI chat as a daemon.
+
+3. Configure `hooks.yml` to map webhooks to SimpleX chatrooms.
+
+4. Run the server and use the client CLI to send notifications.
+
+**Note**: Starting from version 2.2, TellMe supports GoAlert messages natively.
