-## Flow
-1. Obtain a Connectionless Credential Offer from an Issuer.
+## User Flow
 
-A Connectionless Credential Offer is an Out of Band Invitation with a Credential Offer Attachment.
-This should be a URI with a single query parameter `_oob`, which is an encoded JSON.
-It should look similar to:

-2. Ensure the validity of the Invitation with `Agent.parseInvitation`
+  Admin->>Peer: Connectionless Credential Offer Invitation (OOB)
 
-`parseInvitation` decodes and validates the encoded Out of Band Invitation, plus attachments, returning an instance of `OutOfBandInvitation` on success. This OutOfBandInvitation will have a single Attachment for the Credential Offer.
+  Peer ->> Peer: Parse the OOB
+
+  Peer ->> Issuer: Accept the Connectionless Credential Offer Invitation (OOB)
+  Issuer ->> Peer: Connectionless Credential Offer
+  Peer ->> Issuer: Accept the Connectionless Credential Offer
+  Issuer ->> Peer: Verifiable Credential
 
-```
-const oob = await Agent.parseInvitation(rawOob);
 ```
 
-3. Use `Agent.acceptInvitation` to handle the OutOfBandInvitation appropriately.
-In this case, with an attached Credential Offer, the Credential Offer Message will be stored in Pluto.
+## Steps
 
-```
-await Agent.acceptInvitation(oob)
-```
+1. The `Admin` requests a connectionless credential offer invitation with the Issuer Agent
+
+    ```bash
+    curl --location --request POST 'http://localhost:8000/cloud-agent/issue-credentials/credential-offers/invitation' \
+    --header 'Content-Type: application/json' \
+    --data-raw '{
+        "claims": {
+            "emailAddress": "sampleEmail",
+            "familyName": "",
+            "dateOfIssuance": "2023-01-01T02:02:02Z",
+            "drivingLicenseID": "",
+            "drivingClass": 1

+        "issuingDID": [[publishedPrismDID]],
+        "automaticIssuance": true
+    }'
+
+    ```
+
+2. The Issuer sends back the `Connectionless Credential Offer Invitation`
+    - The response should like something like this:
+
+      ```json
+      {
+        "recordId": "cf11283a-a9f5-4da0-ae65-be1e57a40710",

+      }
+      ```
+
+3. The `Admin` forwards the `invitationUrl` on to the `Peer`
+
+4. The `Peer` checks the validity of the `invitationUrl` using `agent.parseInvitation`
+
+      ```typescript
+      const oob = await agent.parseInvitation(invitationUrl)
+      ```
+
+5. The `Peer` accepts the Invitation using `agent.acceptInvitation`
+
+      ```typescript
+      await agent.acceptInvitation(oob)
+      ```
+
+6. The `Issuer` will then send back the credential offer.
+7. The `Peer` listens for the credential offer response from the `Issuer`, and accepts it
+
+    ```typescript
+    agent.addListener(SDK.ListenerKey.MESSAGE, async (newMessages: SDK.Domain.Message[]) => {
+      // newMessages can contain any didcomm message that is received, including
+      // Credential Offers, Issued credentials and Request Presentation Messages
+      const credentialOffers = newMessages.filter(
+        (message) => message.piuri === SDK.ProtocolType.DidcommOfferCredential
+      )
+
+      if (credentialOffers.length) {
+        for (const credentialOfferMessage of credentialOffers) {
+          try {
+            // Create credential offer object from the message
+            const credentialOffer = await SDK.OfferCredential.fromMessage(credentialOfferMessage)
+
+            // Prepare the credential request
+            const requestCredential = await agent.prepareRequestCredentialWithIssuer(credentialOffer)
+
+            // Send the credential request
+            await agent.sendMessage(requestCredential.makeMessage())
+          } catch (err) {
+            console.error('Error occurred while sending the credential request:', err)
+          }
+        }
+      }
+    })
+    ```
+
+8. The `Issuer` sends back the `Verifiable Credential`
+
+9. The `Peer`listens for the credential and stores it in pluto
+
+  ```typescript
+  agent.addListener(SDK.ListenerKey.MESSAGE, async (newMessages: SDK.Domain.Message[]) => {
+    // newMessages can contain any didcomm message that is received, including
+    // Credential Offers, Issued credentials and Request Presentation Messages
+    const issuedCredentials = newMessages.filter(
+      (message) => message.piuri === SDK.ProtocolType.DidcommIssueCredential
+    )
+
+    if (issuedCredentials.length) {
+      for (const issuedCredential of issuedCredentials) {
+        try {
+          // Create issue credential object from the message
+          const issueCredential = await SDK.IssueCredential.fromMessage(issuedCredential)
+
+          // Store the credential in pluto
+          await agent.processIssuedCredentialMessage(issueCredential)
+        } catch (err) {
+          console.error('Error occurred while storing the credential:', err)
+        }
+      }
+    }
+  })
+  ```
