+## Philosophy
+
+The Lysand Protocol is heavily inspired by the [ActivityPub](https://www.w3.org/TR/activitypub/) specification. It is designed to be simple and easy to implement, with a focus on the following concepts:
+- **Simple Structures**: Entities are represented as JSON objects. No JSON-LD, no complex data structures, just plain JSON.
+- **Modularity**: The protocol is divided into a **core protocol** and **extensions**. Implementations can choose to support only the core protocol or add extensions as needed.
+- **Namespacing**: To avoid extension conflicts, all extensions are namespaced.
+- **Signatures**: Most types of interactions **must** be signed with a private key. Unlike other protocols, signatures are **mandatory**, not optional.
+- **Developer-Friendliness**: Understanding and implementing your own Lysand server should be easy. Documentation is aimed at developers first.
