Chad Package Manager is the best package manager. There's nothing more to say.
Open a terminal and run the following commands:
Make a directory for the installer. It is recommended to put this somewhere easy to find, e.g. on the Desktop.
mkdir cpminstaller && cd cpminstaller
Clone the package manager's source code.
git clone https://github.com/Fleli/cpm
Build the package manager. This requires the presence of a C compiler and the make program.
cd cpm && make executable
Chad Package Manager is now available in your terminal through the cpm command.
You may delete the cpm folder after installation.
