You must have python and git installed. Open your terminal program of choice and move to the directory you would like to install to. Then run:

git clone https://github.com/siathema/sefi.git

change into the sefi project directory:

cd ./sefi

Now you must change the file permissions to allow you to execute sefi.py:

chmod a+x ./sefi

Next run sefi with the directory of your choosing to generate a json file for sefi:

./sefi [Path to directory]

If you want to have cron run it every 4 hours at half past the hour then first change your VISUAL enviroment variable to nano:

export VISUAL=nano

This makes it easier to edit using crontab:

crontab -e

Add this entry to your contab file:

MAILTO=user@example.com
