Welcome to Flipper Developer Documentation!

---

This documentation is intended for developers interested in modifying the Flipper Zero firmware, creating Apps and JavaScript programs, or working on external hardware modules for the device.

If you are looking for the user manual, please visit the User Documentation instead.

The documentation is divided into several sections. All of them are accessible from the sidebar on the left:

• Developer Tools — Hardware and software tools for all kinds of programming
• System Programming — Understanding the firmware's internals
• App Development — Developing apps for Flipper Zero
• JavaScript — JS-based scripting engine
• Expansion Modules — Additional modules to expand Flipper's consciousness
• File Formats — Saving and loading data to and from files
• Miscellaneous — Various useful pieces of information

These sections are all manually written. There are also a few automatically generated ones at the bottom of the sidebar:

• Data Structures — Every data structure in a list
• Files — Source file tree with easy navigation

These are generated from the source code and are useful for quickly finding the source code or API documentation for a particular function or data structure.
