 * The install prefix: `--prefix=/path/to/prefix`
 
   * To install with the rest of the assemblies, use:
-  `--prefix="pkg-config --variable=prefix mono"`
+  `--prefix="$(pkg-config --variable=prefix mono)"`
 
 * The build profile: `--profile=profile-name`
 
-  * `stable`: builds the MonoDevelop core and some stable extra add-ins.
-  * `core`: builds the MonoDevelop core only.
-  * `all`: builds everything
+  * `gnome`: builds for Linux
+  * `windows`: builds for Windows
   * `mac`: builds for Mac OS X
 
 **PS:** You can also create your own profile by adding a file to the profiles directory containing a list of the directories to build.
