# Payload Development Basics

Shark Jack payloads are written in Bash with Ducky Script and can be developed in any standard text editor, such as notepad or vi.

Payload files must be named either payload.sh or payload.txt. 

Payloads should begin with the typical shebang /bin/bash.

```
#!/bin/bash
```
