The `slangd` binary can be downloaded as part of [slang releases](https://github.com/shader-slang/slang/releases) or
by [building `slang` from source](https://github.com/shader-slang/slang/blob/master/docs/building.md).

The server can be configured by passing a "settings" object to `slangd.setup{}`:

```lua
require('lspconfig').slangd.setup{
  settings = {
    slang = {
      predefinedMacros = {"MY_VALUE_MACRO=1"},
      inlayHints = {
        deducedTypes = true,
        parameterNames = true,
      }
    }
  }
}
```
Available options are documented [here](https://github.com/shader-slang/slang-vscode-extension/tree/main?tab=readme-ov-file#configurations)
or in more detail [here](https://github.com/shader-slang/slang-vscode-extension/blob/main/package.json#L70).
