-   [official Telegram guide](https://core.telegram.org/bots#3-how-do-i-create-a-bot)
-   for creating a Bot.
-2. Deploy the Bot by clicking on this button:
-   [![Deploy this example](https://deno.com/deno-deploy-button.svg)](https://dash.deno.com/new?url=https://raw.githubusercontent.com/denoland/deploy_examples/main/telegram/mod.ts&env=TOKEN,BOT_NAME)
-3. Input `TOKEN` and `BOT_NAME` env variable fields. The token value should be
-   available from the BotFather and the value `BOT_NAME` is the bot username
-   that ends with either `_bot` or `Bot`.

+2. Open Telegram, talk to [BotFather](https://telegram.me/BotFather) and grab a
+   bot token. Set it as the `BOT_TOKEN` environment variable value.
+3. Click on **Create** to create the project, then on **Deploy** to deploy the
    script.
-5. Grab the URL that's displayed under Domains in the Production Deployment
-   card.
-6. Visit the following URL (make sure to replace the template fields):
+4. Visit the following URL (make sure to replace the template fields):
    ```
-   https://api.telegram.org/bot<YOUR_TOKEN>/setWebhook?url=<DOMAIN_NAME>/<YOUR_TOKEN>
+   https://api.telegram.org/bot<YOUR_TOKEN>/setWebhook?url=<APP_URL>/<YOUR_TOKEN>
    ```
 
-   > Replace <YOUR_TOKEN> with the token from the BotFather and `<DOMAIN_NAME>`
-   > with the URL from the previous step.
+   - Replace `<YOUR_TOKEN>` with the token you got earlier.
+   - Replace `<APP_URL>` with the the URL that is displayed under the
+     **Production Deployment** card at your project dashboard page.
+5. Now send the bot a `/start` or `/ping` command.
 
-7. Add a command to the bot by visiting the following URL:
+<div align="center">
 
-   ```
-   https://api.telegram.org/bot<YOUR_TOKEN>/setMyCommands?commands=[{"command":"ping","description":"Should return a 'pong' from the Bot."}]
-   ```
-8. Now you can invite the bot to a Group Chat or just PM the bot with the
-   following command "/ping".

-## Run Offline
+## Run Locally
 
-You can run the example program on your machine using
-[`deno`](https://github.com/denoland/deno):
+You can run the example on your machine using [Deno CLI](https://deno.land).
 
 ```sh
-TOKEN=<your_telegram_bot_token> BOT_NAME=<bot_username> deno run --allow-env --allow-net https://raw.githubusercontent.com/denoland/deploy_examples/main/telegram/mod.ts
+BOT_TOKEN="<YOUR_TOKEN>" deno run --allow-env --allow-net https://raw.githubusercontent.com/denoland/deploy_examples/main/telegram/local.ts
 ```
 
-You need to use a tool like [ngrok](https://ngrok.com) to tunnel Telegram
-requests to the app running on your machine.
-
-1. Run `ngrok http 8080` (assuming that the application is running on port
-   `8080`)
-2. While registering the bot, use the https URL output by ngrok for **url**
-   query.
-
-> Example:
-> `https://api.telegram.org/bot<YOUR_TOKEN>/setWebhook?url=<ngrok_url>/<YOUR_TOKEN>`
-
-That's it.
+Remember to replace the `<YOUR_TOKEN>` with your own bot token.
