+
+== Legal Status
+
+This project is legally licensed under the **Mozilla Public License 2.0 (MPL-2.0)**.
+
+The Palimpsest Licence is a philosophical and ethical framework that accompanies the legal license. **Palimpsest does not currently provide legal protections** - it is a manifesto and a set of principles that we encourage adopters to embrace alongside the MPL-2.0.
+
+== Why MPL-2.0 + Palimpsest?
+
+=== The Legal Foundation: MPL-2.0
+
+The Mozilla Public License 2.0 provides:
+
+* **File-level copyleft** - modifications to MPL-licensed files must remain open
+* **Compatibility** - can be combined with proprietary code and other open source licenses
+* **Patent protection** - includes explicit patent grants
+* **Clear, modern language** - well-drafted and widely understood
+
+=== The Philosophical Layer: Palimpsest
+
+Palimpsest adds an ethical dimension that legal licenses cannot capture:
+
+* **Layered contribution** - like a palimpsest manuscript, each contributor adds to what came before
+* **Transparent provenance** - clear attribution of ideas, not just code
+* **Collaborative evolution** - encouraging forks that improve rather than fragment
+* **Ethical use guidelines** - principles beyond what law can enforce
+
+== Future Direction
+
+**Palimpsest v0.5** will integrate MPL-2.0 and Palimpsest principles into a single, legally recognized license. This work is ongoing.
+
+Until then:
+
+1. **MPL-2.0** is the legally binding license for this project
+2. **Palimpsest** is the philosophical framework we encourage you to adopt
+3. Distributing Palimpsest alongside your use of this code is encouraged but not required
+
+== Get Involved
+
+We are actively developing Palimpsest as a real, legally recognized license that captures both the legal and ethical dimensions of open source collaboration.
+
+If you are interested in:
+
+* Contributing to the Palimpsest license design
+* Adopting Palimpsest for your own projects
+* Providing legal expertise on open source licensing
+* Discussing the philosophy behind Palimpsest
+
+**Please get in touch:**
+
+* GitHub: https://github.com/hyperpolymath
+* Palimpsest Licence repo: https://github.com/hyperpolymath/palimpsest-licence
+
+== Signing Up to Palimpsest
+
+While Palimpsest is not yet legally formalized, you can signal your support by:
+
+1. Adding the Palimpsest badge to your project README
+2. Including `PALIMPSEST.adoc` in your repository
+3. Mentioning Palimpsest in your LICENSE file
+4. Joining discussions about the license's development
