If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/lemon
%  sudo port install lemon  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching lemon
--->  Verifying checksum for lemon
--->  Extracting lemon
--->  Configuring lemon
--->  Building lemon with target all

--->  Staging lemon into destroot

--->  Installing lemon

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using lemon with these commands:

%  man lemon
%  apropos lemon
%  which lemon
%  locate lemon
