+# eepp SDK
+
+Self-contained snapshot of the [eepp](https://github.com/SpartanJ/eepp) framework:
+runnable demos and tools, the assets they need, and the compiled libraries ready to be
+linked against by your own applications.
+
+Version: @SDK_VERSION@ ("nightly" is a rolling build of the latest development
+changes; eepp-%d.%d.%d versions are stable releases)
+
+## Package layout
+
+```
+bin/                    Tools and examples/demos (release builds)
+bin/assets/             Assets required by the shipped binaries
+bin/                    Runtime libraries co-located with the binaries
+libs/<platform>/<arch>/ Libraries for linking against eepp
+include/                Public C++ headers
+docs/articles/          Framework documentation articles
+```
+
+## Running the demos and tools
+
+Every binary in `bin/` is ready to run:
+
+- **Windows:** double-click any `.exe`.
+- **Linux:** run any binary from a file manager or a terminal, for example
+  `bin/ecode`. The binaries locate the shared libraries relative to their own
+  location (`$ORIGIN` rpath), so the package can live anywhere on disk.
+- **macOS:** the shipped binaries and libraries are ad-hoc signed and resolve
+  their dependencies through `@loader_path`, so they can be launched straight
+  from Finder or a terminal.
+
+If the SDL2/SDL3 runtime library was not bundled next to the binaries (see
+`bin/`), install it with your system package manager (for example
+`libsdl2-2.0-0` on Debian/Ubuntu).
+
+## Linking against eepp
+
+Add `include/` to your include path and link against the libraries in
+`libs/<platform>/<arch>/`:
+
+- Dynamic linking: link against the shared library (`eepp.dll` / `libeepp.so` /
+  `libeepp.dylib` and the matching import library when applicable).
+- The optional modules (`eepp-maps`, `eepp-physics`) and the `eterm` /
+  `languages-syntax-highlighting` static libraries are also provided.
+
+Start with the documentation in `docs/articles/` and the sources of the shipped
+examples (available in the repository under `src/examples/`) to learn the API.
+
+## Notes
+
+- These are unstable nightly builds; APIs may change at any time.
