+# DOC_REVIEW: fix-install-update-flow
+
+## Reviewed Documentation
+
+1. `README.md` -- updated install instructions
+2. `CHANGELOG.md` -- task 8 entry
+
+## Findings
+
+### 1. README.md
+
+Install instructions updated to show:
+- `git clone <your-git-url> ~/.automaton` (placeholder instead of hardcoded URL)
+- `./install.sh <your-git-url>` (URL as argument)
+- Note about self-improvement loop being created by default
+- Note about choosing URL carefully
+
+**Accuracy:** Matches the implementation. The URL is required as `$1`.
+
+**Verdict:** PASS
+
+### 2. CHANGELOG.md
+
+Entry accurately describes all 5 fixes: git URL, venv cwd, Windows venv path, hook copy, version check. Lists all 3 changed scripts and the 15 new tests.
+
+**Verdict:** PASS
+
+### 3. Cross-reference check
+
+- `design/loops/technical.md` section 9 references `install.sh` -- still accurate (the self-improvement loop bootstrap is still there, just the URL handling changed).
+- `AGENTS.md` references `install.sh` in the repo layout -- no changes needed.
+- `prompts/onboarding.md` references hook installation -- no changes needed (hooks are installed via `install-hooks.sh`, which is unchanged).
+
+## Summary
+
+All documentation is accurate and consistent with the implementation.
+
+**Verdict: APPROVED**
