Or you can download a prebuilt binary from our [Releases](https://github.com/zellij-org/zellij/releases).
As the default plugins make use of characters that are mostly only found in [nerdfonts](https://www.nerdfonts.com/),
you get the best experience either with installing nerdfonts, or telling the plugins that you request a ui, that
does not rely on such characters with `zellij options --simplified-ui`, or putting `simplified_ui: true` in the
config file.
The default plugins make use of characters that are mostly found in [nerdfonts](https://www.nerdfonts.com/).
To get the best experience either install nerdfonts, or use the simplified ui by starting Zellij with `zellij options --simplified-ui`, or putting `simplified_ui: true` in the config file.
## How do I hack on it? (Contributing)
* Clone the project
* Install cargo-make with `cargo install --force cargo-make`
* In the project folder, for debug builds run: `cargo make run`
* To run all tests: `cargo make test`
For more build commands, see [`Contributing.md`](CONTRIBUTING.md).
