 ## Developer Setup
 
-You'll need:
+We use `pnpm`: `pnpm` does what `npm` does but is much more efficient.
+Recommended setup is as follows:
 
-- [Node](https://nodejs.org/en/) (we develop this with Node v20.11.0 LTS)
-- `npm` (which comes with Node)
-- [git](https://git-scm.com/)

-Then install `pnpm` ([instructions](https://pnpm.io/installation)). `pnpm`

-`node` versions for you.
+1. Follow installation instructions for `pnpm` [here](https://pnpm.io/installation).
+2. Open a new shell and verify that `pnpm` is installed by running `pnpm --version`.
+3. Run `pnpm env use --global lts` to download the latest LTS version of Node.
+4. Clone this repository and navigate to the project directory within your shell.
+5. Run `pnpm install` to install all dependencies.
+6. Test that everything works by running `pnpm staging_start` to start the development server.
 
 There are actually two different ways to run the app locally on your machine -

 ### Connecting to a backend
 
 #### Using the Staging Server (Recommended)
 
-We'll follow the standard node project workflow. Type the following lines into your command line:
+After following the **Developer Setup**, run:
