 Chapter 1.1: Retrieving the image
 =================================
 
-Before you install Lubuntu, you need to retrieve the correct image.
+Before you install Lubuntu, you need to retrieve the correct image. Lubuntu offers two different kinds of images,
+Alternate and Desktop images. Lubuntu also provides support for many different CPU architectures. Lubuntu releases a
+new version every six months (supported for nine (9) months), with every two years having a long term support release
+(supported for three (3) or five (5) years, depending on the release).
+
+Choosing between alternate and desktop
+--------------------------------------
+Alternate images are mainly intended for older, lower spec hardware and uses a non-graphical installer. The desktop
+version offers a live session to try out Lubuntu and make sure all of your hardware works before you install it on
+your computer. The installer on the desktop is a graphical installer where you can use a mouse and keyboard and it is
+more user friendly, but this takes more resources than what is usually required to run Lubuntu itself, due to the
+fact that the desktop image runs from your RAM while Lubuntu normally runs from your hard drive. If your computer has
+less than 512 MB of RAM it is recommended to use the alternate installer as it will perform better with your system.
+The alternate installer does not provide a live session so therefore it uses less RAM.
+
+Lubuntu offers images for three different architectures:
+ - amd64 (commonly referred to as 64-bit)
+ - i386 (commonly referred to as 32-bit)
+ - PowerPC
+
+amd64
+------
+The amd64 image will work with most modern processors. The best way to determine if your computer has an amd64 or
+i386 processor is to boot the image. It's the only way that you will be able to know for sure what architecture your
+computer is. amd64 computers are backwards compatible with i386 images. You may want to use an i386 image instead if
+you have an amd64 processor with very low amounts of RAM.
+
+
+i386
+----
+This is the original 32-bit architecture that will work best on computers with very low amounts of RAM.
+
+
+PowerPC
+-------
+
+PowerPC is for older Macintosh hardware from before 2006 and IBM OpenPower systems.
+
+
+Now that the decision of which image type and archetecture is done you will need to download the image and check to make sure it is accurate.
