Prereq:

If you want to change the hostname, follow this [guide](https://graspingtech.com/change-hostname-ubuntu-16-04/).

```bash
sudo apt update -y && sudo apt install -y zsh git-core
```

Getting zsh to work in ubuntu is weird, since `sh` does not understand the `source` command.  So, you do this to install zsh

    wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

and then you change your shell to zsh

    sudo su
    chsh -s $(which zsh) ubuntu

and then restart

    sudo shutdown -r 0

This problem is explained in depth in [this issue](https://github.com/robbyrussell/oh-my-zsh/issues/227#issuecomment-825773)

Next step, you probably want to change the **theme**. My personal favourite is [maran](https://github.com/robbyrussell/oh-my-zsh/wiki/themes#maran).
