 Contributions are welcome! We're currently breaking apart the Scattebrain component into smaller, more manageable packages. If you have a package that you think would be useful to others, please open a PR.
 
+# Installation for Development
+
+This project uses [Node.js](https://nodejs.org) and [pnpm](https://pnpm.io/). We use [Volta](https://volta.sh/) to manage the versions of each. If you're not using Volta, check the "volta" key in the root `package.json` for the Node and pnpm versions we're using when developing.
+
+Volta has experimental support for pnpm, so [follow the steps on their docs](https://docs.volta.sh/advanced/pnpm) to get it enabled.

 # Using the Libraries
 
 See the `docs/using-packages.md` file for information on how to use the packages in your own projects.
