+# Telegram Bot Webhook
+
+The frontend can act as a Telegram Bot webhook endpoint, to add BGP route/traceroute/whois lookup functionality to your tech group.
+
+There is no configuration necessary on the frontend, just start it up normally.
+
+Set your Telegram Bot webhook URL to `https://your.frontend.com/telegram/alpha+beta+gamma`, where `alpha+beta+gamma` is the list of servers to be queried on Telegram commands, separated by `+`.
+
+You may omit `alpha+beta+gamma` to use all your servers, but it is not recommended when you have lots of servers, or the message would be too long and hard to read.
+
+## Example of setting the webhook
+
+```bash
+curl "https://api.telegram.org/bot${BOT_TOKEN}/setWebhook?url=https://your.frontend.com:5000/telegram/alpha+beta+gamma"
+```
+
+## Supported commands
+
+- `path`: Show bird's ASN path to target IP
+- `route`: Show bird's preferred route to target IP
+- `trace`: Traceroute to target IP/domain
+- `whois`: Whois query
