# Configuring payloads Complex payloads often have configuration options to tune behavior. Configuration variables are found at the top of the payload. Well-formed payloads will document the payload options in comments; for example: ```bash #!/bin/bash # Title: Printer Capture # # Description: Capture PCL IP printer jobs with a dynamic proxy # Do we automatically exfiltrate to Cloud C2? Uncomment to send files to your # CloudC2 server automatically # # USE_C2=1 # By default, C2WATCHDIR removes files after they're sent. To keep them, uncomment # C2_KEEP_FILES below # # C2_KEEP_FILES=1 ``` ## Editing payloads Payloads can be edited in the Packet Squirrel web UI, via `ssh`, or downloaded, edited, and re-uploaded using either the Packet Squirrel web UI or `scp`.
