Fix bash cmdline for installing dependencies

[Stronkness]

Currently in the README.md file the bash line indicates to insert the python dependencies one by one. However, there is a requirements.txt file that is not used which installs this. I rewrote the command so that it used the file to install all depedencies needed instead.

As a sidenote, i dont know if pywin32 works everywhere. I have a Linux machine and it doesnt find pywin32 on my machine.

The requirements.txt file is just for reference, that's why it has the extension .txt.
The instructions are given in the README.md, to install all dependencies in one go.

This line in README.md does it in one go:
pip install docx2pdf ppt2pdf fpdf Pillow img2pdf pywin32

Yes, pywin32 is not available in linux.
The software is works in Windows only as of now.
If you have any alternative of pywin32 for linux, you are most welcome to add in project.

The line which i changed also installs everything but from the file instead which is more convenient.
Is there something wrong about my line in your opinion? Just asking :)

[suraj-singh12]

It's fine, but it becomes redundant as the instructions are already given in the README.md itself.
Also, the purpose of requirements.txt is just to store the packages' names, just for the user's reference.
