 Introduction
 ************
 
-The first step is to unwrap your mesh. You want to unwrap when you feel your mesh is complete
-with respect to the number of faces it needs to have.
+The first step is to unwrap your mesh. Generally, it is a good idea to unwrap when you
+feel that your model is mostly complete.
 If you do add faces or subdivide existing faces when a model is already unwrapped,
 Blender will add those new faces for you,
 but you may need to do additional mapping or editing. In this fashion,

 The lines joining the UVs correspond to edges in the mesh.
 Each face in the UV map corresponds to a mesh face.
 
+Think of a UV map as projecting the surface of your 3D model onto a 2D image.
+
 Each face of a mesh can have many UV textures.
 Each UV texture can have an individual image assigned to it.
 When you unwrap a face to a UV texture in the UV Editor, each face of the mesh is
 automatically assigned four UV coordinates: These coordinates define the way an image or
-a texture is mapped onto the face. These are 2D coordinates, which is why they are called UV,
-to distinguish them from XYZ coordinates.
+a texture is mapped onto the face. To distunguish from xyz coordinates, we use the U and V
+axes to mark the coordinates of each point. Hence the name, UV unwrapping.
 These coordinates can be used for rendering or for real-time viewport display as well.
 
 Every face in Blender can have a link to a different image.

 Workflow
 --------
 
-The process for unwrapping is straightforward, but there are a lot of options available,
-each of which dramatically affect the outcome of the unwrap.
-By understanding the meaning behind the options, you will become more efficient at unwrapping.
+The general workflow is as follows, but know that different models may require different approaches
+to unwrapping.
 
 The process is:
 
-#. Mark Seams if necessary.
-#. Select all of the mesh components.
-#. Select a UV mapping method from the UV Unwrap menu.
-#. Adjust the unwrap settings.
-#. Add a test image to see if there will be any distortion.
-   See :doc:`Applying Images to UVs </modeling/meshes/uv/applying_image>`.
-#. Adjust UVs in the UV editor.
-   See :doc:`Editing UVs </modeling/meshes/uv/editing>`.
+#. Mark Seams if necessary. See more about :doc:`marking seams </modeling/meshes/uv/unwrapping/seams>`.
+#. Select all of the mesh components in the 3D viewport.
+#. Select a UV mapping method from the UV Unwrap menu. Select a method from the dropdown named "UV" under the 
+   proportional editing button in the 3D viewport.
+#. Adjust the unwrap settings found in the pop up box at the bottom right of the 3D viewport.
+#. Add a test image to see if there will be any distortion. See 
+   :doc:`Applying Images to UVs </modeling/meshes/uv/applying_image>`.
+#. Adjust UVs in the UV editor. See :doc:`Editing UVs </modeling/meshes/uv/editing>`.
