+# libcall-ui
+
+Libcall-ui carries common user interface parts for call handling. It is meant
+to be used as a git submodule.
+
+## License
+
+libcall-ui is licensed under the LGPLv2.1-or-later.
+
+## Getting the source
+
+```sh
+    git clone https://gitlab.gnome.org/guido/libcall-ui.git
+    cd libcall-ui
+```
+
+The main branch has the current development version.
+
+## Dependencies
+See `meson.build` for required dependencies.
+
+## Building
+
+We use the meson (and thereby Ninja) build system for phosh.  The quickest
+way to get going is to do the following:
+
+    meson . _build
+    ninja -C _build
+    ninja -C _build install
+
+## Running the demo
+You can run the contained demo via:
+
+    _build/examples/call-ui-demo
