-The General Device Type Format (GDTF) creates a unified data exchange definition for the operation of intelligent luminaires, such as moving lights. By creating a manufacturer-supported, unified standard, customers/users of lighting control systems, CAD systems, and pre-visualizers benefit by knowing the tools they use to perform their job will work consistently and dependably. The file format is developed using open source formats, and luminaire manufacturers in the entertainment design, production, and performance industries are welcome to use this open source technology.

+**GDTF**: The `General Device Type Format` is an open standard for describing devices of the entertainment industry. These devices may be lighting fixtures, trusses, distribution boxes, media servers, lasers or other devices used in the entertainment industry. [This documentation](https://github.com/mvrdevelopment/spec/blob/main/gdtf-spec.md) describes [DIN SPEC 15800:2022-02](https://www.beuth.de/en/technical-rule/din-spec-15800/349717520) also known as GDTF, version 1.2.
+
+**MVR**: The `My Virtual Rig` file format is an open standard which allows programs to share data and geometry of a scene for the entertainment industry. A scene is a set of parametric objects such as fixtures, trusses, video screens, and other objects that are used in the entertainment industry. [This documentation](https://github.com/mvrdevelopment/spec/blob/main/mvr-spec.md) describes [DIN SPEC 15801:2023-12](https://www.dinmedia.de/en/technical-rule/din-spec-15801/373968511) also known as MVR, version 1.6.
