Installing `zls` is pretty simple;

```bash
|

git clone https://github.com/SuperAuguste/zls

Then, you can use the `zls` executable in an editor of your choice that has a Zig language server client!
|

|
||||
*Note:`zls` itself must be built using the master branch of zig currently due to a bug in `std.json` which was [fixed](https://github.com/ziglang/zig/pull/5167) after 0.6.0 was released.*

### Configuration Options

You can configure zls by providing a zls.json file in the same directory as the executable.
