 ## Software Pipeline (Precision Feedback Pipeline)
 ### Recipient annotation generation (Bitstomach)
 The first stage of the pipeline is a script called Bitstomach. This script analyzes recipient's performance data and generates features called **annotations**. These annotations describe features of the performance data such as performance trends over time, or how performance measures relate to other values like peer performance benchmarks and institutional performance goals.
