| <p>git add \<filename></p><p> or </p>        | git commit -m "example message" | git push origin master |
| <p>git add . </p><p>(to add all changes)</p> |                                 |                        |

{% hint style="info" %}
Use the following command so that whenever you push, you can store your credentials and don't have to type them every single time you push.
{% endhint %}

| store git credentials              |   |
| ---------------------------------- | - |
| git config credential.helper store |   |

{% hint style="warning" %}
Note that nothing will appear, however next time you push and are prompted to enter your credentials they will be stored and you will no longer be prompted for them.
{% endhint %}

Alternatively you can use the following set of commands :

```
git config --global user.name "your username"

git config --global user.password "your password"

git config --global user.email "your email(used for github)"
```
