Documentation Improvements

by Malcolm Mackay

We have published documentation for cuplTag, which shows how to program the MSP430 and how to configure it with serial-port commands. This information is hosted in our GitHub repository.

The cuplTag documentation incldues a detailed guide on how to deploy your own web application. It is important to us that this web-based technology does not become overly centralized, which is why we made it open. Users should now have sufficient information to deploy an independent system of cuplTags.

More documentation will be added in the near future.

Manufacturing Status

Our CEM has informed us that assembly of the first 10 boards will commence next week!
