Detailed Installation Walkthrough

To install the RFID Client application, follow the steps below:

1. Clone the repository using the following command:

   git clone https://github.com/VinnieV/crid.git

2. Navigate to the cloned repository:

   cd crid

3. If you have Python 3 installed, pip3 should be available. If not, you can install Python 3 and pip3 by following the instructions provided in the links below:

   • Install Python 3
   • Install pip3

4. Install the application using pip3. There are two ways to install pip packages: as a user or system-wide. Choose the appropriate method based on your requirements:

   System-wide:

   pip3 install .

   User-wide:

   pip3 install . --user

5. Add the Python Scripts directory to your PATH environment variable. This step is necessary to ensure that the crid binary is accessible from anywhere in the command prompt or terminal. The process for adding the Python path to the PATH variable differs between Windows and Linux:

   • Windows:

     • Open the Start menu and search for "Environment Variables".
     • Click on "Edit the system environment variables".
     • In the System Properties window, click on the "Environment Variables" button.
     • In the "System Variables" section, select the "Path" variable and click on "Edit".
     • Execute the following command to retrieve the path:

     pip3 show crid

     • Based on the Location listed there you can find the Python Scripts folder, the path should look something similar like this:

     c:\users\<username>\appdata\local\packages\pythonsoftwarefoundation.python.3.8_qbz5n2kfra8p0\localcache\local-packages\python38\Scripts

     • Click "OK" to save the changes.

   • Linux:

     • Open a terminal window.
     • Edit the .bashrc or .bash_profile file in your home directory using a text editor (e.g., nano ~/.bashrc).
     • Add the following line at the end of the file:

     export PATH="$PATH:$HOME/.local/bin/"

     • Save the file and exit the text editor.
     • Run the following command to apply the changes:

     source ~/.bashrc

Once you have completed these steps, you should be able to use the RFID Client application successfully.
