 ## Requirements
 
-- NPM
-- Node
-- Bun (for running locally, so we can run TypeScript directly)
+- Bun
 
 ## Running Locally
 
 The easiest way to test is to set this up in a standalone Slack instance and
 then use a local proxy like [ngrok](https://ngrok.com/).
 
 - Create a Slack application (see Slack Bolt API link below)
-- Run `npm run dev` (it defaults to port 3000)
+- Run `bun install` to install dependencies
+- Run `bun run dev` (it defaults to port 3000)
 - Run ngrok to create a proxy to your Bolt app (`ngrok serve 3000`)
 - Point your Slack's event subscription to your ngrok URL
 - Set up [Sonos Proxy](https://github.com/clearfunction/sonos_proxy_nodejs)
