PLEASE NOTE: Alfred is currently in beta and as such, these help pages are currently being developed.
If you are using 0.6.1+ then updating pre-releases is easy, simply select the pre-releases checkbox on the preferences general > update tab and perform the Sparkle update as usual.

Please be aware that running Alfred on a pre-release version will always be safe but may be unstable.
If you are experiencing problems, please report them in the "Bugs" tab in Alfred's main Preference panel.
If you are tracking pre-releases, please follow us on twitter @twitter.
