+Hello, there.
+
+Using CMake to build Conky is pretty easy, and here is how I do it:
+
+1. From the top level source dir, create a build working dir, and cd into it
+  $ mkdir build
+  $ cd build
+2. Run the cmake configuration process
+  $ cmake ../ # pass the path to the sources to cmake
+  OR
+  $ ccmake ../ # you can also use the fance curses interface, or try cmake-gui
+3. Compile as usual, and enjoy the out-of-source goodness
+  $ make
+  # make install # if you want
+
+
+NOTE: I haven't actually finished the CMake build system yet, because I'm lazy.  I'll add all the different options eventually though.
