| ## Usage | ||
|
|
||
| Let's consider a hypothetical deal we want to track in Filecoin. Each deal will have a series of states it can be in, and various things that can happen to change its state. We will track multiple deals at the same time. In this example, we will model the actions of the receiving party (i.e. the person who accepted the deal and responding) |

Goals
Provide basic module documentation since that is a source of confusion
Provide guidance on using FSM module beyond examples in test
Implementation
go-storage-miner
