To install the ZlsNasDisplay project using Poetry, you can follow these steps:

1.  **Clone the Repository**: First, clone the repository containing the project's code from GitHub:
    
    bashCopy code
    
    `git clone https://github.com/zales/ZlsNasDisplay.git`
    
2.  **Navigate to the Project Directory**: Change your current directory to the root directory of the cloned project:
    
    bashCopy code
    
    `cd ZlsNasDisplay`
    
3.  **Install Dependencies**: Use Poetry to install the project's dependencies defined in the `pyproject.toml` file:
    
    bashCopy code
    
    `poetry install`
    
4.  **(Optional) Create a Virtual Environment**: If you prefer to isolate the project's dependencies, you can create a virtual environment with Poetry:
    
    bashCopy code
    
    `poetry shell`
    
5.  **Run the Project**: After installing the dependencies, you can run the ZlsNasDisplay project using Poetry. For example, if there's a script defined in the `pyproject.toml` file under `[tool.poetry.scripts]`, you can execute it as follows:
    
    bashCopy code
    
    `poetry run python3 zlsnasdisplay`
