## Set up your tools

By executing scripts from _Install_ folder.

Execute `deep-upgrade`, `basic-install` and `basic-custom` before any tweak.

### Hostname

Change hostname with `sudoedit /etc/hostname`

Reboot.

### Tweaks

Scripts are named `<component>-<task>` where `<component>` is the part to be tweaked and `<task>` the purpose of the script, which can be _install_ to install software of this part and _custom_ to configure them as Jovian does.

Installation must be made before customization.

### Fish prompt

Execute command `set fish_color_user yellow`.

Execute command `set fish_color_host blue|red|yellow|magenta` depending of the power regulation.

## Set up SSH

### Add client id key

```sh
vim .ssh/authorizedkeys
```
Test if working.

### Remove password authentication

```sh
sudoedit /etc/ssh/sshd_config
```

### Create id to connect to servers

```sh
ssh-keygen -f id_server_eddsa -t ed25519
```

Then add the generated public key to servers.
