+## Workflow
+
+Please submit a PR from a **new branch** in your fork.
+Please do not submit a PR from your fork's `main` branch, as it makes collaborating on/editing the branch a pain.
+
+## Project design
+
+- Compiled CSS styles are built and committed from SCSS sources. See the `compile_assets` folder for details.
+- `mdbook-admonish install` is responsible for delivering additional assets and configuration to a client book.
+- `mdbook-admonish` is responsible for preprocessing book data, adding HTML that references compiled classnames.
+
+## Scripts to get started
+
+- `./scripts/install` installs other toolchains required for development
+- `./scripts/check` runs a full CI check
+- `./scripts/rebuild-book` rebuilds the reference book under `./book`. This is useful for integration testing locally.
+
+## Making breaking changes in CSS
+
+To make a breaking change in CSS, you should:
+
+- Update the assets version in `./src/bin/assets/VERSION`
+- Update the required assets version specifier in `./src/REQUIRED_ASSETS_VERSION`
+
+You must make the next `mdbook-admonish` crate version at least a **minor** version bump.
+
+## Releasing
+
+Github workflows are setup such that pushing a `vX.Y.Z` tag will trigger a release to be cut.
