This is a little exemple of an custom theme.</br>
If you are using `format_top/bottom` & `corner_top/bottom`, `format` will be ignored.</br>
For making a single line prompt use `format`, and double line `format_top/bottom`.</br>
N.B : `path_slash_color` & `path_words_color` works with single and double line shell prompt.
Exemple :
```json
{
"name": "test",
"format": "[bold green][[{user}@{host}]][/][white][[{cwd}]] >>[/]",
"format_top": "[bold cyan]{user}@{host}[/]",
"format_bottom": "[bold yellow]{cwd}[/]",
"format_top": "[[[bold cyan]{user}[/]@[bold cyan]{host}[/]]]",
"format_bottom": "[[{cwd}]]",
"corner_top": "[bold magenta]\u250c[/]",
"corner_bottom": "[bold magenta]\u2514[/]",
"ls_colors": "di=34:fi=37:ln=36:pi=33:so=35:ex=32"
"ls_colors": "di=34:fi=37:ln=36:pi=33:so=35:ex=32",
"path_slash_color": "cyan",
"path_words_color": "yellow"
}
```

The name of the theme is `test`, no matter what the file is named.</br>
So enter the command : `settheme test`.</br>
This is the result :
