+## Authenticate to GitHub

+
+First method: Generate / grab a valid GitHub access token. With this in hand run...
+
+```
+git config --global credential.helper store
+git push  # Enter username and token (will be cached)
+```
+

+
+```
+git config --global user.name "Your Name"
+git config --global user.email "[email protected]"
+git pull
+git add .
+git commit -m "Use double quotes for this comment"
