 <title>Common Tasks</title>
     <para>
-        This chapter describes standard tasks such as adding new
-        software packages, extending or customizing images, and porting work to
-        new hardware (adding a new machine).
-        The chapter also describes how to combine multiple
-        versions of library files into a single image, how to handle a package name alias, and
-        gives advice about how to make changes to the Yocto Project to achieve the best results.
+        This chapter describes fundamental procedures such as creating layers,
+        adding new software packages, extending or customizing images,
+        porting work to new hardware (adding a new machine), and so forth.
+        You will find the procedures documented here occur often in the
+        develop cycle using the Yocto Project.
