+## Disclaimer
+
+This project is an unofficial, community-maintained collection of patches for
+[Antigravity IDE](https://antigravity.dev). It is **not affiliated with,
+endorsed by, or sponsored by Google LLC or any of its subsidiaries.**
+
+## Nature of the Project
+
+Better Antigravity provides **bugfix patches** that restore documented, expected
+functionality in Antigravity IDE. Specifically:
+
+- The "Always Proceed" terminal execution policy is documented to auto-execute
+  commands, but does not function as described. Our patch restores this behavior.
+- All patches are non-destructive: they create automatic backups and can be
+  fully reverted at any time.
+- No data is collected, transmitted, or shared with any party.
+
+## Compliance
+
+- This project **does not access** Google's backend servers, APIs, or
+  authentication systems.
+- This project **does not extract** AI models, training data, or proprietary
+  algorithms.
+- This project **does not bypass** security features, licensing, or
+  usage restrictions.
+- All modifications are local to the user's machine and affect only the
+  client-side UI behavior.
+
+## Interoperability
+
+Where applicable, this project relies on the right to achieve interoperability
+as provided by:
+
+- **EU Software Directive** (Directive 2009/24/EC), Article 6
+- **UK Copyright, Designs and Patents Act 1988**, Section 50B
+- Similar provisions in other jurisdictions

+3. This project may stop working after Antigravity updates — in that case,
+   revert and wait for an updated patch.
+
+## Takedown
