+# Manual API Test – Steel Thread
+
+This folder contains a **manual API test** used to support the **steel thread** for the Clinical Data Gateway (CDG).
+
+The intent of this test is to:
+
+- Validate that a response is returned using the **expected structure**
+- Support early preparation and understanding only
+
+This is **not automated testing** and **does not prove functional completeness**.
+
+## Steel Thread Scope
+
+For the steel thread, CDG supports **reading a patient record for a single patient** using the following structure:
+
+```bash
+POST https://[CDG_server]/FHIR/STU3/patient/$gpc.getstructuredrecord
+```
+
+- FHIR version: **STU3**
+- Format: **FHIR JSON**
+- Operation: **custom GP Connect FHIR operation**
+- Scope: **single patient**
+
+No error handling, authentication edge cases, or non-happy paths are covered.
+
+## Tooling
+
+This manual test uses **usebruno** as the API testing tool.
+
+Bruno is:
+
+- Free and open source
+- Installed locally
+
+The Bruno collection for this test lives **inside this repository**, so no external workspace or account is required.
+
+## Installing Bruno (macOS)
+
+Bruno can be installed using Homebrew.
+
+1. Install Homebrew:
+
+   ```bash
+   https://brew.sh/
+   ```
+
+2. Install Bruno:
+
+   ```bash
+   brew install bruno
+   ```
+
+3. Launch Bruno:
+
+   ```bash
+   bruno
+   ```
+
+## Opening the Bruno Collection
+
+To add it in Bruno:
+
+1. Open Bruno
+2. Select **Open Collection**
+3. Navigate to:
+
+   ```text
+   clinical-data-gateway-api/gateway-api/tests/manual-test/api-test
+   ```
+
+4. Open the folder
+
+The collection is now loaded and ready to use.
+
+## Running the Manual Test
+
+1. Select the **Retrieve Patient Record** request in the collection
+2. Set Bruno to use the local environment
+3. In terminal run `node mock-response.js`. Output should read `Mock Retrieve Patient Record server running at http://localhost:8080`
+4. Send the request
+
+A successful response should return a **FHIR STU3 response** that aligns with the expected steel-thread response shape.
