Not only can you add a new skin, but you can also import an existing skin (FLSKN file).
How to import a skin
In the Project Organizer, right-click on the Skins folder and select Add Skin.
OR
The Add Skin dialog opens.
.Click Open.
The Source File field now contains the path to the file that you are importing. Also, the name of the file is displayed in the File Name field.
Click Add.
The skin is added and opens in the Skin Editor.
Note: In addition to importing single files from another location (which this topic discusses), you can import linked files from a Flare source project using a featured called "Global Project Linking." This is different than a simple import process, because in this case, the imported files remain linked to the source project. This allows you to make future updates to those files in just one place—in the source project file. When you perform ongoing imports using your previous settings, Flare recognizes changes to the source files. Therefore, the new files can be brought over, replacing the outdated files.
Note: You can download a variety of free skins with different looks from the MadCap Software website. Simply go to http://madcapsoftware.com/downloads/utilities/flareskingallery.aspx. After downloading the skin, you can import it into your project.
After you import a skin, you can edit its settings and then associate it with a target.
