+A Go implementation of a passive secure two-party protocol for blood type compatibility based on BeDOZa.
 
 ## Implementation
 
-The protocol is implemented in `cmd/handin1/main.go` with tests in `cmd/handin1/main_test.go`. 
+The protocol is implemented in `cmd/handin3/main.go` with tests in `cmd/handin3/main_test.go`.

 You can run the tests with go:
 ``` 
-go test ./cmd/handin1
+go test ./cmd/handin3
 ```
 
 This executes the protocol tests. This includes a test that tries the protocol on all combinations of recipient and donor blood types.
