+### 5.1 HTTPS
+
+If you want to run your FastAPI app over HTTPS locally you can use [mkcert](https://github.com/FiloSottile/mkcert) and pass the certificate and key to `uvicorn`.
+
+0. Install `mkcert` (see instructions [here](https://github.com/FiloSottile/mkcert))
+1. cd into "openbb_sdk/sdk/core/openbb_core/api"
+2. Run the following commands:
+
+    ```shell
+    mkcert -install
+    mkcert localhost 127.0.0.1 ::1
+    ```
+
+    You will see two files created in the current directory.
+    - Certificate: "localhost+2.pem"
+    - Key: "localhost+2-key.pem"
+
+3. Change the code to start the server inside "rest_api.py" to:
+
+    ```python
+    if __name__ == "__main__":
+        import uvicorn
+
+        uvicorn.run(
+            "openbb_core.api.rest_api:app",
+            reload=True,
+            ssl_keyfile="./localhost+2-key.pem",
+            ssl_certfile="./localhost+2.pem",
+        )
+    ```
+
+4. Run the server from the terminal with:
+
+    ```shell
+    python rest_api.py
+    ```
+
+    Your app will be available at https://127.0.0.1:8000/
