sets your repo's local config so that your commits show proper name and link to your github account

add-github-user-details.sh

#!/bin/bash

# queries you for github username and name
# sets your name, and your email as:
# name  : <input-name>
# email : <input-github-username>@users.noreply.github.com

echo -n "Enter the name you want in your commits: "
read name
echo -n "Enter the github ID you want referenced: "
read id

# why replace-all and not add? | http://stackoverflow.com/a/17317076/1527814

# setup name for commits
git config --local --replace-all user.name "$name"
# setup email for commits
git config --local --replace-all user.email "${id}@users.noreply.github.com"
