+Installation
+============
+
+*a2jmidid* uses the |meson| build system.
+
+
+Configure and build
+-------------------
+
+To configure the project, |meson|'s |meson_universal_options| (e.g. *prefix*)
+can be used to prepare a build directory::
+
+  meson --prefix=/usr build
+
+One additional - project specific - option enables for building without |dbus|
+support::
+
+  meson --prefix=/usr -Ddisable-dbus=true build
+
+To build the application |ninja| is required::
+
+  ninja -C build
+
+Install
+-------
+
+|meson| is able to install the project components to the system directories
+(when run as root), while honoring the *DESTDIR* environment variable::
+
+  DESTDIR="/some/other/location" meson install -C build
