+# Car Insurance -- Persistence
+
+This CorDapp demonstrates how Persistence works in Next Gen Corda. 
+Corda allows developers to have the ability to expose some or all parts of their states to a custom database table using an ORM tools. To support this feature the state must implement QueryableState.
+
+
+## Concepts
+This CorDapp allows two nodes to enter into an IOU agreement, but enforces that both parties belong to a list of sanctioned entities. This list of sanctioned entities is taken from a referenced SanctionedEntities state.
+
+## Usage
+
+
+### Setting up
+
+1. We will begin our test deployment with clicking the `startCorda`. This task will load up the combined Corda workers in docker.
+   A successful deployment will allow you to open the REST APIs at: https://localhost:8888/api/v1/swagger#. You can test out some
+   functions to check connectivity. (GET /cpi function call should return an empty list as for now.)
+2. We will now deploy the cordapp with a click of `5-vNodeSetup` task. Upon successful deployment of the CPI, the GET /cpi function call should now return the meta data of the cpi you just upload
+
+
+
+### Running the app
+
+In Corda 5, flows will be triggered via `POST /flow/{holdingidentityshorthash}` and flow result will need to be view at `GET /flow/{holdingidentityshorthash}/{clientrequestid}`
+* holdingidentityshorthash: the id of the network participants, ie SanctionBody, Bob, Charlie and DodgyParty. You can view all the short hashes of the network member with another gradle task called `ListVNodes`
+* clientrequestid: the id you specify in the flow requestBody when you trigger a flow.
+
+
+### Running the flows
+
+Pick the SanctionBody VNode identity to issue the sanctions list
+Go to `POST /flow/{holdingidentityshorthash}`, enter the identity short hash(SanctionBody's hash) and request body:
+
+    {
+    "clientRequestId": "issue-sanction",
+    "flowClassName": "com.r3.developers.samples.persistence.workflows.IssueSanctionsListFlow",
+    "requestBody": {
+      }
+    }
+
+Now that the sanctions list has been made, Next, we want to issue an IOU. Pick Bob VNode identity to issue the IOU.
+Go to `POST /flow/{holdingidentityshorthash}`, enter the identity short hash(Bob's hash) and request body:
+
+    {
+      "clientRequestId": "issue-iou",
+      "flowClassName": "com.r3.developers.samples.persistence.workflows.IOUIssueFlow",
+      "requestBody": {
+      "iouValue": 100,
+      "lenderName": "CN=Charlie, OU=Test Dept, O=R3, L=London, C=GB",
+      "sanctionAuthority": "CN=SanctionsBody, OU=Test Dept, O=R3, L=London, C=GB"
+      }
+    }
+
+We've seen how to successfully send an IOU to a non-sanctioned party, so what if we want to send one to a sanctioned party? First we need to update the sanction list.
+Go to `POST /flow/{holdingidentityshorthash}`, enter the identity short hash(SanctionBody's hash) and request body:
+
+    {
+      "clientRequestId": "update-sanction",
+      "flowClassName": "com.r3.developers.samples.persistence.workflows.UpdateSanctionListFlow",
+      "requestBody": {
+      "partyToSanction": "CN=DodgyParty, OU=Test Dept, O=R3, L=London, C=GB"
+      }
+    }
+
+
+Now try an issue an IOU to DodgyParty. Go to `POST /flow/{holdingidentityshorthash}`, enter the identity short hash(Bob's hash) and request body:
+
+    {
+      "clientRequestId": "issue-iou-1",
+      "flowClassName": "com.r3.developers.samples.persistence.workflows.IOUIssueFlow",
+      "requestBody": {
+      "iouValue": 100,
+      "lenderName": "CN=DodgyParty, OU=Test Dept, O=R3, L=London, C=GB",
+      "sanctionAuthority": "CN=SanctionsBody, OU=Test Dept, O=R3, L=London, C=GB"
+      }
+    }
+
+The flow will error with the message: The borrower O=DodgyParty, L=Moscow, C=RU is a sanctioned entity'!
+
+You could use the GetIOUFlow and GetSanctionListFlow to query the vault and check the current unconsumed states
+issued on the ledgers. Go to `POST /flow/{holdingidentityshorthash}`, enter the vnode's identity short hash and request body:
+
+To Get IOU List:
+
+    {
+       "clientRequestId": "get-iou",
+       "flowClassName": "com.r3.developers.samples.persistence.workflows.GetIOUFlow",
+       "requestBody": {
+       }
+    }
+
+To Get Sanction List:
+
+    {
+       "clientRequestId": "get-sanction",
+       "flowClassName": "com.r3.developers.samples.persistence.workflows.GetSanctionListFlow",
+       "requestBody": {
+       }
+    }
