+# Post-Generation Updates
+
+> **MANDATORY**: After creating or adding any Azure Function, perform these three steps.
+
+## 1. File Naming Convention
+
+Name function source files after their **route or purpose**, not the generic trigger type.
+
+| Route / Purpose | ✅ Correct filename | ❌ Avoid |
+|-----------------|---------------------|---------|
+| `/api/random` | `src/functions/random.js` | `httpTrigger.js` |
+| `/api/users` | `src/functions/users.js` | `httpTrigger.js` |
+| `/api/health` | `src/functions/health.js` | `httpTrigger.js` |
+| Cosmos DB change feed | `src/functions/cosmosProcessor.js` | `function1.js` |
+| Scheduled job | `src/functions/dailyReport.js` | `timerTrigger.js` |
+
+**Rules:**
+- Derive the name from the route segment (e.g., `/api/random` → `random`) or the purpose (e.g., `dailyReport`)
+- Use camelCase for multi-word names (e.g., `userProfile.js`, `orderProcessor.js`)
+- Trigger-type suffixes are optional; prefer the shortest descriptive name
+- Do **not** use generic names like `httpTrigger`, `function1`, or `index` unless unavoidable
+
+## 2. README Update
+
+After adding a new function, update (or create) the project's `README.md`:
+
+1. **Add to endpoints table** – include function name, route, method, auth level, and description
+2. **Add curl example** – provide a ready-to-run `curl` command for local and deployed testing
+3. **Document env variables** – list any new environment variables the function requires
+
+### Template
+
+````markdown
+## Available Endpoints
+
+| Function | Route | Method | Auth | Description |
+|----------|-------|--------|------|-------------|
+| `<functionName>` | `/api/<route>` | GET/POST | anonymous/function | <description> |
+
+### Test locally
+
+```bash
+curl http://localhost:7071/api/<route>
+```
+
+### Test deployed
+
+```bash
+curl https://<functionapp>.azurewebsites.net/api/<route>
+```
+````
+
+### Example (route `/api/random`)
+
+````markdown
+## Available Endpoints
+
+| Function | Route | Method | Auth | Description |
+|----------|-------|--------|------|-------------|
+| `random` | `/api/random` | GET | anonymous | Returns a random number |
+
+### Test locally
+
+```bash
+curl http://localhost:7071/api/random
+```
+
+### Test deployed
+
+```bash
+curl https://<functionapp>.azurewebsites.net/api/random
+```
+````
+
+## 3. Test File Updates
+
+After adding a new function, update the project's test files.
+
+### If a `test.http` file exists
+
+Append a request block for the new function:
+
+```http
+### <FunctionName> - local
+GET http://localhost:7071/api/<route>
+
+### <FunctionName> - deployed
+GET https://{{functionAppName}}.azurewebsites.net/api/<route>
+```
+
+For POST endpoints, include a body:
+
+```http
+### <FunctionName> POST - local
+POST http://localhost:7071/api/<route>
+Content-Type: application/json
+
+{
+  "key": "value"
+}
+```
+
+### If a `testdata.json` (or similar data file used with curl) exists
+
+Append an entry for the new function's expected input/output:
+
+```json
+{
+  "<functionName>": {
+    "route": "/api/<route>",
+    "method": "GET",
+    "expectedStatus": 200
+  }
+}
+```
+
+### If neither `test.http` nor a testdata file exists
+
+Create a `test.http` file at the project root with a request block for the new function (see template above).
