+## Python Flight Software
 
 ## Development
-
-Use `pipenv` to manage the development environment.
+1. Clone this repo
+2. Use `pipenv` to manage the development environment.
 More information on `pipenv` available in the [documentation](https://pipenv.readthedocs.io/en/latest/).
 If you already have `pipenv` installed, run:
 ```
 pipenv install  # Install dependencies
 ```
-Alternatively, configure your IDE to use the pipenv as the Python interpreter.
-
-## Usage
+* Alternatively, configure your IDE to use the pipenv as the Python interpreter.
+3. Activate the `pipenv shell`
+4. Run `python3 main.py`
 
+## Dependencies
+- `Python 3.6` or greater is required along with `pip`
+### Usage
 `invoke` is used as the task runner.
 Ensure that you install `invoke` globally (not in your virtual environment) using `pip3 install invoke`.
 Below are the available commands:
 
 - `invoke run`: Run the flight software.
     - `invoke run -d`: Debug mode.
     - `invoke run -p`: Production mode, use this when running on a staging or production environment.
-- `invoke deploy`: Install all required packages _globally_. Only run this on a staging or production environment.
-
-
-## Dependencies
-* `smbus`/`smbus2` are not compatible with Windows `cmd.exe`, either:
-    * Use Linux/WSL to install and run
-    * Run remotely on `pi-cubesat` with `ssh`
+- `invoke deploy`: Install all required packages _globally_. Only run this on a staging or production environment.
