 ## Developer Setup
 
 You'll need:
 
-- [Node](https://nodejs.org/en/) (we develop this with Node v14.15.5 LTS)
+- [Node](https://nodejs.org/en/) (we develop this with Node v20.11.0 LTS)
+- `npm` (which comes with Node)
 - [git](https://git-scm.com/)
-- either `npm` (which comes default with Node) or [yarn](https://yarnpkg.com/en/)
 
-There are actually two different ways to run the app locally on your machine - one that uses our staging backend server, and one where you'll run it locally. Usually, the staging server is totally fine to use, but having the backend makes more sense if you're working on a new feature or are editing the backend.
+Then install `pnpm` ([instructions](https://pnpm.io/installation)). `pnpm`
+does what `npm` does but is much more efficient. Also, it can manage different
+`node` versions for you.

 ### Connecting to a backend

-### Running Into This Weird Error?
-
-If you have followed these steps and are running into Node.js errors like the
-following: `error:0308010C:digital envelope routines::unsupported`, it may be
-because you are running an newer version of Node that we currently do not target.
-
-To fix this issue, revert to Node v16 (we develop with Node v16.20.0). To do so without interfering with any existing
-Node installation (and as a proper future-proofing measure), install a version manager for Node: Windows
-users should follow directions to install [nvm for Windows](https://github.com/coreybutler/nvm-windows), and
-Mac/Linux users should follow directions to install [nvm for POSIX systems](https://github.com/nvm-sh/nvm).

 ## Notes for Developers:
 
-- every time you pull from master, make sure to run `npm install` - it's likely that some dependency has changed!
+- every time you pull from master, make sure to run `pnpm install` - it's likely that some dependency has changed!
 - `lint-staged` and `husky` auto-prettify some JS code on save - don't be spooked!
 - GitHub Actions auto-builds branches and PRs - make sure that `npm run test` `npm run prod_build` pass, or your changes for-sure won't work!
 - Netlify auto-deploys PRs, branches, and production deploys using the contents of `npm run prod_build`!
