 To work on this codebase **you need**:
 
 - Node.js >= v16 (prod env is node v16)
-- An AWS account with the AWS CLI configured locally
-- Copy `.env.tpl` to `.env.local`
 - Install the deps with `npm i`
 
-Deploy dev services to your aws account and start dev console
+You can then run the tests locally with `npm test`. 
 
-```console
-npm start

+[`sst`](https://sst.dev) is the framework we use to define what to deploy. Read the docs! https://sst.dev
 
 ## Deployment 
 
-Deployment is managed by [seed.run]. PR's are deployed automatically to `https://<pr#>.up.web3.storage`. 
+Deployments are managed by [seed.run]. 
 
 The `main` branch is deployed to https://staging.up.web3.storage and staging builds are promoted to prod manually via the UI at https://console.seed.run
 
+### Local dev
+
+You can use `sst` to create a custom dev deployment on aws, with a local dev console for debugging.

+- An AWS account with the AWS CLI configured locally
+- Copy `.env.tpl` to `.env.local`
