This is how I do it for version 2.0.
1. Make a profile for 2.5 or 3 gallons.
2. Make a copy of the 5 gallon recipe you want to scale.
3. Open the copy and under "profile", click on pull down menu and select the profile you want.
Hope this helps.
Always do sober what you said you would do drunk. That will teach you to keep your mouth shut. - Ernest Hemingway
