+# Phase 0: Research
+
+## Testing Strategy
+
+**Decision**: Use Vitest for unit testing Astro components and Playwright for end-to-end testing.
+
+**Rationale**: 
+- **Vitest**: It's a fast and modern test runner that's compatible with Vite, which Astro uses under the hood. It's easy to set up and has a similar API to Jest.
+- **Playwright**: It's a powerful end-to-end testing framework that allows testing across different browsers. It's great for simulating user interactions and verifying the complete functionality of the site.
+
+**Alternatives considered**:
+- **Jest**: A popular testing framework, but Vitest is more modern and better integrated with the Vite ecosystem.
+- **Cypress**: Another popular end-to-end testing framework, but Playwright has better cross-browser support.
+
+## Performance Goals
+
+**Decision**: Aim for a Google Lighthouse score of 90+ for Performance, Accessibility, Best Practices, and SEO.
+
+**Rationale**: This is a widely accepted benchmark for web performance and user experience. Achieving these scores will ensure a fast and accessible website.
+
+**Alternatives considered**: None, as this is a standard best practice.
+
+## Constraints
+
+**Decision**: The project should be completed within 3 months and stay within a budget of $10,000.
+
+**Rationale**: These constraints are based on the client's requirements.
+
+**Alternatives considered**: None.
+
+## Scale/Scope
+
+**Decision**: The initial scope is to migrate the existing content from the old site to the new Astro and Payload CMS setup. This includes ~50 blog posts and ~20 portfolio items.
+
+**Rationale**: This is based on the analysis of the existing sitemap and CMS structure.
+
+**Alternatives considered**: None.
