+## Development tasks
+
+To verify that static assets build correctly:
+
+```shell
+npm run build-storybook
+```
+
+To run tests locally, you must first install the `playground` development dependencies and playwright. From there, you can run tests
+
+```shell
+# set up playground
+cd playground
+npm install
+cd ..
+npx playwright install --with-deps
+
+# run tests, with optional debugging
+npm run test
+npm run test-dev
+```
+
+You can typecheck and lint using:
+
+```shell
+# check types, a11y, and other component quality
+npm run check
+
+# autoformat code and documentation
+npm run format
+
+# check formatting without writing files
+npm run format-check
+
+# lint for stylistic and correctness issues
+npm run lint
+```
