 ## Compiling
 
 This project can be compiled for simulation environments or directly on the hardware.

+## Running story

+To execute an example usage of the project, execute `./src/simulate`. 
+Note, that this will only work, if you sucessfully compiled the project.

+## Manual Usage
+
+### Setup
+
+Go to the `src` directory.
 
-# Usage
-## Setup
 Initialize the Enclave keypair by executing:
 `./signatureproxy proxysetup -pkey <sealed_proxy_key.bin> > <proxy_public_key.pem>` 
 
-## Sign
+### Sign
 1. Create employee signature using `./signatureproxy employee -firm <firmware.bin> -ekey <employee_privat_key.pem> > <employee_signature.der>`
    This step can also be done using OpenSSL: `openssl dgst -sha256 -sign <employee_private_key.pem> -out <employee_signature.der> -in <firmware.bin>`
 2. Use the signature proxy to resign the firmware using `./signatureproxy proxy -pkey <sealed_proxy_key.bin> -epub <employee_public_key.der> -firm <firmware.bin> > <proxy_signature.der>`
