Go to the releases page and download the latest archive for your platform. Extract it and define a variable pointing to the binary:
tar xzf text2confl-*.tar.gz
T2C=$(pwd)/text2conflVerify it works:
$T2C --versionTo use text2confl directly from any directory in the future, move the binary to a location on your PATH (e.g. mv ./text2confl /usr/local/bin/).
