+  <p>This section explains basic aspects of CMake, mostly for
+    explaining those options which you may need on your day-to-day
+    usage.</p>
+
+  <p>CMake comes with extensive documentation in the form of html
+    files and on the cmake executable itself. Execute <i>cmake
+    --help</i> for further help options.</p>
+
+  <p>CMake requires to know for which build tool it shall generate
+    files (GNU make, Visual Studio, Xcode, etc). If not specified on
+    the command line, it tries to guess it based on you
+    environment. Once identified the build tool, CMake uses the
+    corresponding <i>Generator</i> for creating files for your build
+    tool. You can explicitly specify the generator with the command
+    line option <i>-G "Name of the generator"</i>. For knowing the
+    available generators on your platform, execute</p>
+
+    <div class="doc_code">
+      <p><tt>cmake --help</tt></p>
+    </div>
+
+    <p>This will list the generator's names at the end of the help
+      text. Generator's names are case-sensitive. Example:</p>
+
+    <div class="doc_code">
+      <p><tt>cmake -G "Visual Studio 8 2005" path/to/llvm/source/root</tt></p>
+    </div>
+
+    <p>For a given development platform there can be more than one
+      adequate generator. If you use Visual Studio "NMake Makefiles"
+      is a generator you can use for building with NMake. By default,
+      CMake chooses the more specific generator supported by your
+      development environment. If you want an alternative generator,
+      you must tell this to CMake with the <i>-G</i> option.</p>
+
+    <p>TODO: explain variables and cache. Move explanation here from
+      #options section.</p>
