Describe a bit about how your effect works.  Feel free to use multiple lines, 
just don't delete or change any of the field names. 

Effect name: Orange octagon
Effect description:  Uses the slicer to create a rhythmic pattern of filter 
effects

Left pot label:  Base Freq
Left pot function: Adjusts the base frequencies of the filters

Center pot label: Output gain
Center pot function: Adjusts the output gain

Right pot label: Spread Freq
Right pot function: Adjusts the spread frequencies of the filters

Left footswitch label: Bypass
Left footswitch function: Bypasses the effect

Right footswitch label: Tap speed
Right footswitch function: Tap a few times to set the speed of the slicer
