i have recently migrated to Linux Ubuntu from Windows. how do i install software using source code

change directory to source code folder
cd /home/dinhunzvi/Downloads/theFolder
./configure && make && sudo make install

if it is python don't do configure stuffs. Just cd to dir and do
sudo python setup.py install
