     \title Handling External Libraries
 
-    Knowing external libraries is not only important for the
-    underlying build system, but also for Qt Creator itself.
-    This way, it can support code completion and syntax highlighting 
-    for external libraries as if they were part of the current 
-    project or the Qt library.
-
-    The way to add a library to the project depends on the 
-    project type, which influcences the build system used. 
-    The following sections describe the the procedure required
-    for each project type.

     {Declaring other Libraries} section of the Qt documentation.
 
-    If your project does sucessfully build and link against
-    the external library, syntax completion and highlighting
-    should also work.

     \section1 CMake Projects
 
-    In CMake, libaries are usually detected using the \c{FIND_PACKAGE()} macro.
+    In CMake, libraries are usually detected using the \c{FIND_PACKAGE()} macro.
     A couple of them are already being shipped with CMake, they can be found in
     the \c{Modules} directory of your CMake installation. If you provide 
     libraries on your own, you will need to provide your own \c{FindFoo.cmake}
