# Git
Git is a version control system — it tracks changes in your code and lets you collaborate safely.
To install:
```zsh
brew install git
```
Then verify if it installed correctly:
```zsh
git --version
```
#### Set Identity
Set your name and email so Git knows who is making changes. Use the same name and email as your GitHub account so your commits are properly linked.
```
git config --global user.name "Your Name"
git config --global user.email "your@email.com"
```
These will get added to your `.gitconfig` file.
## SSH Keys
You can generate SSH keys for your machine by running:
```zsh
ssh-keygen
```
Then press **Enter** three times.
Navigate to:
```zsh
cd ~/.ssh
```
Type `ls -a` and you should your private key and public key
Then type `cat id_ed25519.pub` to print your public key, so you can copy-paste it to GitHub/Bitbucket.
