+# Step 0: readme-usage-flow
+
+## Read First
+- /AGENTS.md
+- /PLAN.md
+- /PROGRESS.md
+- /docs/HARNESS.md
+- /docs/IMPLEMENTATION_PLAN.md
+- /README.md
+- /phases/7-mvp-quality-hardening/index.json
+
+## Task
+Update README usage flow for the MVP CLI.
+
+Document install, validation, basic conversion, formula parser modes, runtime modes, output layout, resume, and logs.
+
+## Sprint Contract
+- Done means: a user can follow README instructions to run the local CLI on Windows after environment setup.
+- Hard thresholds: commands match implemented CLI; docs do not promise PyQt or hosted API as MVP; generated output contract is accurate.
+- Files owned: `README.md`, docs as needed, `PROGRESS.md`, `phases/8-release-docs-packaging/index.json`.
+- Dependencies: MVP quality hardening complete.
+
+## Acceptance Criteria
+```powershell
+python scripts\validate_workspace.py
+```
+
+## Verification
+1. Run the acceptance command.
+2. Confirm documented commands are copy-pasteable in PowerShell.
+3. Update `PROGRESS.md` and this phase index.
+
+## Do Not
+- Do not document unimplemented features as available.
+- Do not add marketing-style content.
+- Do not include model weights in the repository.
