#!/bin/sh

# Instructions:
# Step 1 - Create a new empty folder called 'MyLog' (or similar)
# Step 2 - Inside that folder drop this file called log.sh (or similar)
# Step 3 - Make the log.sh file executable
# Step 4 - Run the following commands:
#          git init
#          git add .
#          git commit -m "MyLog Initialised"
# Step 5 - Now you have a git repo that will act as a log, to run:
#          ./log.sh
