+## Contributing to this repo
+
+This repository is managed by EasyCLA. Project participants must sign the free
+[GraphQL Specification Membership agreement](https://preview-spec-membership.graphql.org)
+before making a contribution. You only need to do this one time, and it can be
+signed by
+[individual contributors](https://individual-spec-membership.graphql.org) or
+their [employers](https://corporate-spec-membership.graphql.org).
+
+To initiate the signature process please open a PR against this repo. The
+EasyCLA bot will block the merge if we still need a membership agreement from
+you.
+
+You can find
+[detailed information here](https://github.com/graphql/graphql-wg/tree/main/membership).
+If you have issues, please email
+[operations@graphql.org](mailto:operations@graphql.org).
+
+If your company benefits from GraphQL and you would like to provide essential
+financial support for the systems and people that power our community, please
+also consider membership in the
+[GraphQL Foundation](https://foundation.graphql.org/join).
+
+## Running a new build
+
+- Install the latest version of Node and NPM
+- Install the Node dependencies with `npm install`
+- Build a new spec with `npm run build`
+  - This will output the new spec text in `/public` as HTML files
+
+## Contributing to the spec text
+
+### Auto-Formatting
+
+The specification is formatted using the `prettier` tool, so you should not need
+to think about gaps between paragraphs and titles, nor about word wrapping -
+this is handled for you.
+
+### Adding spec examples
+
+To keep things consistent in the spec, we should use examples that reference an
+e-commerce store. We should use types like `Product`, `User`, `Review`, etc.
+
+### Adding new sections
+
+Sections in the spec document are nested under top level sections, then topic
+sections, then specific sections. We should aim to limit to 3 nested levels and
+consider flattening once we reach 4 levels.
