# QuadToneProfiler Support and Documentation
This wiki-based site is the new home for the instructions and documentation for all the QuadToneProfiler applications. There is a lot of information that applies to all the apps so instead of needing to replicate it for each set of instructions, I made this site so that I can easily update and link new information as needed.
### Support Questions
If you have any additional questions or problems with the applications please email me at
[email protected]
If you encounter bugs or crashes please include any related measurement and .quad files in your email.
