Cannot install on WSL2

[shaal]

On Windows WSL2, I follow these instructions: https://github.com/Algolzw/daclip-uir#install
First 3 steps are working as expected

python3 -m venv .env
source .env/bin/activate
pip install -U pip

When I run the 4th step, pip install -r requirements.txt, I get this error -
ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'

The error shows that the requirements.txt is not in your current folder. Please check it or copy the file to your current directory.
