+## Development
+
+### Taste
+
+- No Amending. Never use `git commit --amend`. Always create new, discrete commits for every set of changes.
+- Inferred types over annotations. `any` is the enemy.
+
+### Build and Test
+
 - This project uses bun. Examples: `bun run lint`, `bun run build`, `bun run test --no-watch`.
+- Run a single spec file: `bun run test -- --include="src/app/utils/form.utils.spec.ts" --no-watch`
+- Run a single test by name (regex): `bun run test -- --filter="toPositiveNumber" --no-watch`
+- To get test code coverage run: `bun run test -- --coverage --no-watch`
