# PAROL6 sources and licences

> For agents: start with the [agent guide](https://parol6.build/llms.txt). Every page is Markdown by default; add `Accept: text/html` for HTML.

## The official sources

- **[The PAROL6 manual](https://docs.source-robotics.com/PAROL-docs/1.1/)**, release 1.1, by Source Robotics. Milestones 1 to 4 follow it step by step. Its source lives in [PAROL-docs](https://github.com/Source-Robotics/PAROL-docs).
- **[The robot repository](https://github.com/Source-Robotics/PAROL6-Desktop-robot-arm)**: STL files, the BOM, the [building instructions PDF](https://github.com/Source-Robotics/PAROL6-Desktop-robot-arm/blob/main/Building%20instructions/Parol%20building%20instructions.pdf), the [print table](https://github.com/Source-Robotics/PAROL6-Desktop-robot-arm/blob/main/Print%20table/PR_EXCEL.xlsx), and the firmware.
- **[The commander software](https://github.com/Source-Robotics/PAROL-commander-software)**: jogging, a 3D simulator and RBTscript programs.

## Licences

The [repository README](https://github.com/Source-Robotics/PAROL6-Desktop-robot-arm) states the licences:

- **Hardware** is under the CERN Open Hardware Licence Version 2, Strongly Reciprocal (CERN-OHL-S-2.0). That covers everything in the repository except the firmware: the STL files, the BOM, the building instructions, the print table and the robot models.
- **Firmware** in the main software and test code folders is under GPL-3.0. The libraries in their `lib` folders keep their own licences.

This wiki links official images and PDFs and does not copy them. Quotes stay short and cite their page.

## Other sources

- [Doepfer's A-100 construction details](https://www.doepfer.de/a100_man/a100m_e.htm) define the Eurorack format used from [M5](/lore/m5-touch-the-skiff) on.
- [Four-component instructional design](https://www.4cid.org/) shapes how the [milestones](/lore/milestones) are built.

## Terms

- **CERN-OHL-S-2.0**: the strongly reciprocal CERN Open Hardware Licence, version 2, which covers PAROL6's hardware files ([repository README](https://github.com/Source-Robotics/PAROL6-Desktop-robot-arm)).
- **GPL-3.0**: the GNU General Public License, version 3, which covers PAROL6's firmware ([repository README](https://github.com/Source-Robotics/PAROL6-Desktop-robot-arm)).
- **official sources**: the Source Robotics manual and repositories listed on this page.
