 ## Installation
 
-Basically it is just:
+The build file also contains an install target, e.g.:
+
+    $ DESTDIR=dest ninja-build install
+    [1/1] Install the project...
+    -- Install configuration: "Release"
+    -- Installing: dest/usr/local/bin/somake
+    [..]
+
+If you use the standard makefile generator with cmake, just
+replace `ninja-build` with `make`. Also, omitting the `DESTDIR`
+installs everything for real. The destdir mechanism is useful for
+preparing a binary package and just to have a preview.
+
+To change the default install prefix, you have to call `cmake`
+differently, e.g.:
+
+    $ cmake ../somake -DCMAKE_INSTALL_PREFIX=/usr \
+        -DCMAKE_BUILD_TYPE=Release -G Ninja
+    $ DESTDIR=dest ninja-build install
+    [..]
+    -- Install configuration: "Release"
+    -- Installing: dest/usr/bin/somake
+    [..]
+
+
+### Manual Installation
+
+In case you prefer a manual installation, basically it is just:
 
 - copy the created `somake` binary to a `bin/` directory under some prefix
 - copy the man page into the related manpath
