+Erebos/C++
+==========
+
+Library implementing the Erebos identity management, decentralized messaging
+and synchronization protocol, along with local storage. Specification being
+created at:
+
+[http://erebosprotocol.net](http://erebosprotocol.net)
+
+Erebos identity is based on locally stored cryptographic keys, all
+communication is end-to-end encrypted. Multiple devices can be attached to the
+same identity, after which they function interchangeably, without any one being
+in any way "primary"; messages and other state data are then synchronized
+automatically whenever the devices are able to connect with one another.
+
+Status
+------
+
+This is experimental implementation of yet unfinished specification, so
+changes, especially in the library API, are expected. Storage format and
+network protocol should generally remain backward compatible, with their
+respective versions to be increased in case of incompatible changes, to allow
+for interoperability even in that case.
+
+Build
+-----
+
+This library uses CMake for building:
+
+```
+cmake -B build
+cmake --build build
+```
+
+Usage
+-----
+
+The API is currently experimental and without documentation; some example of
+usage can be found in the test executable (`src/main.cpp`).
