The file that you will download varies depending on which package manager you use. Refer to your distribution's manual for information on how to install packages for your system. For Ubuntu and Debian distributions, this is sprite-packer_{version}_amd64.deb.
Open up the location of the download in your file system.
Using your package manager, install the package that you downloaded.

When you first open the app, you will be asked to choose a folder location. This will be where your sprites are stored (Note: Not an animation folder containing the PNG files!). You can change this location at any time by clicking on Options at the top of the app and selecting Set Sprites Path.
Before packing, you must check that each sprite and its duplicates are identical by clicking on the "Check" button at the bottom. Any sprites that are not identical will appear in the "Changed Sprites" list on the right. You can then click the sprite that you want to replace all duplicates with and then click on the "Replace Duplicates" button to replace them.
After packing, a file dialog will open to ask where to save the generated atlas.
