 You can use the **`path`**, **`urlMethods`**, **`headers`**, and **`host`** filters together or independently based on your testing scenarios. This flexibility allows you to precisely define the conditions under which tests are recorded.
 
+### Managing Secrets with `secret.yaml`
+
+Keploy allows you to manage sensitive information like API keys or tokens securely, without hardcoding them into your test files. This is done using a `secret.yaml` file within each test set directory.
+
+1.  **Create `secret.yaml`**: Inside your test set directory (e.g., `keploy/test-set-0/`), create a file named `secret.yaml`.
+
+2.  **Define Your Secrets**: Add your secrets as key-value pairs.
+    ```yaml
+    # path: keploy/test-set-0/secret.yaml
+    API_KEY: "your-super-secret-api-key"
+    AUTH_TOKEN: "bearer-token-xyz-123"
+    ```
+
+3.  **Use Secrets in Tests**: Reference these values in your test cases or mocks using the `{{.secret.KEY}}` syntax.
+    ```yaml
+    # inside a test-case.yaml
+    ...
+    header:
+        Authorization: "Bearer {{ .secret.AUTH_TOKEN }}"
+    ...
+    ```
+For your security, Keploy will automatically add `/*/secret.yaml` to your `.gitignore` file to prevent accidentally committing secrets.

 ### Bypass Rules Section
 
 The `bypassRules` section in the Keploy-config file allows you to define parameters for bypassing and mocking API calls.
