 ## Workflow
 
-- [ ] Install package
-- [ ] Find test files with `as` assertions: `grep -r " as [A-Z]" --include="*.test.ts" --include="*.spec.ts"`
-- [ ] Replace `as Type` with `fromPartial()`
-- [ ] Replace `as unknown as Type` with `fromAny()`
-- [ ] Add imports from `@total-typescript/shoehorn`

+1. **Gather requirements** - ask user:
+   - What test files have `as` assertions causing problems?
+   - Are they dealing with large objects where only some properties matter?
+   - Do they need to pass intentionally wrong data for error testing?

+2. **Install and migrate**:
+   - [ ] Install: `npm i @total-typescript/shoehorn`
+   - [ ] Find test files with `as` assertions: `grep -r " as [A-Z]" --include="*.test.ts" --include="*.spec.ts"`
