+### Meson Build options
+
+Build options can be specified during meson setup or later via meson configure.
+
+    meson -D<option>=<value> .build
+
+The following options are available:
+
+-   **without_tests**: _(boolean)_ diable tests  
+    `meson -Dwithout_tests=true .build`
+
+-   **without_adapter**: _(boolean)_ omit adapter library  
+    `meson -Dwithout_adapter=true .build`
+
+-   **without_provider**: _(boolean)_ omit provider library
+    `meson -Dwithout_provider=true .build`
+
+_Note that unit tests are only available, when both libraries are built._
 
 ## Create API documentation
