### Colorschemes

gotop ships with a few colorschemes which can be set with the `-c` flag followed by the name of one. You can find all the colorschemes in the [colorschemes folder](./colorschemes).

To make a custom colorscheme, check out the [template](./colorschemes/template.go) for instructions and then use [default.json](./colorschemes/default.json) as a starter. Then put the file at `~/.config/gotop/<name>.json` and load it with `gotop -c <name>`. Colorschemes PR's are welcome!

### CLI Options

`-m`, `--minimal` Only show CPU, Mem and Process widgets.  
`-r`, `--rate=RATE` Number of times per second to update CPU and Mem widgets [default: 1].
