+## SCITT API Emulator Spin Up

+```console
+$ git clone https://github.com/microsoft/scitt-api-emulator

+$ python -m rich.markdown README.md
+$ ./scitt-emulator.sh server --workspace workspace/ --tree-alg CCF
+Setting up Python virtual environment.
+[notice] A new release of pip available: 22.2.2 -> 22.3.1
+[notice] To update, run: pip install --upgrade pip
+Service private key written to workspace/storage/service_private_key.pem
+Service parameters written to workspace/service_parameters.json
+Service parameters: workspace/service_parameters.json

+- Ran commands from `README.md`
+
+```console
+$ ./scitt-emulator.sh server --workspace workspace/ --tree-alg CCF
+$ ./scitt-emulator.sh client create-claim --issuer did:web:example.com --content-type application/json --payload '{"sun": "yellow"}' --out claim.cose
+$ ./scitt-emulator.sh client submit-claim --claim claim.cose --out claim.receipt.cbor
+$ ./scitt-emulator.sh client retrieve-claim --entry-id 1 --out claim.cose
+$ ./scitt-emulator.sh client retrieve-receipt --entry-id 1 --out receipt.cbor
+$ ./scitt-emulator.sh client verify-receipt --claim claim.cose --receipt claim.receipt.cbor --service-parameters workspace/service_parameters.json
+```
+
+- It works!
+
+> The `verify-receipt` command verifies a SCITT receipt given a SCITT claim and a service parameters file. This command can be used to verify receipts generated by other implementations.
+>
+> The `service_parameters.json` file gets created when starting a service using `./scitt-emulator.sh server`. The format of this file is not standardized and is currently:
+>
+> ```json
+> {
+>     "serviceId": "emulator",
+>     "treeAlgorithm": "CCF",
+>     "signatureAlgorithm": "ES256",
+>     "serviceCertificate": "-----BEGIN CERTIFICATE-----..."
+> }
+> ```
+
+- We upload `alice shouldi contribute` dataflow to SCITT and get a receipt!
+  - Friends, today is a great day. :railway_track:
+  - Next stop, serialization / federation with Alice / Open Architecture serialization data flow as SCITT service.
