 modules to minimize the library footprint. Using the build files you can create
 a static and a shared lib containing all modules, but you may also use the UCX
 sources in your project and compile specific modules by yourself to further
-minimize the footprint.
+minimize the footprint, e.g. when you need lists, but do not need hash maps.
 
 
 2. Build
 --------
 
-The build processes uses CMake starting with UCX 3.0.
-You can clone the repository or download the sources from SourceForge.
+The build processes requires executing a simple configure script and calling
+make. You can clone the repository or download the sources from SourceForge.
 
     wget https://sourceforge.net/projects/ucx/files/ucx-latest.tar.gz
     tar -xzf ucx-latest.tar.gz
     cd ucx-latest
 
-Then create a build directory and use cmake to create the build files,
-execute the build, and - optionally - install the files.
+Then execute ./configure with the options you like. You can get a list of
+all available options with ./configure --help. The recommended configuration
+for production builds is ./configure --release.
 
-    mkdir build
-    cd build
-    cmake ..
-    cmake --build .
-    sudo cmake --install .
+    ./configure --release
+    make
+    make check                 # only available when built with tests
+    sudo make install
