+# Helix
+
+## Quick Start
+
+- **Step 1.** [Install KCL](https://kcl-lang.io/docs/user_docs/getting-started/install) on your system. Please ensure that `kcl` and `kcl-language-server` are installed and added to your PATH:
+  On MacOS and Linux:
+
+  ```bash
+  which kcl
+  which kcl-language-server
+  ```
+
+  On Windows:
+
+  ```bash
+  where kcl
+  where kcl-language-server
+  ```
+
+- **Step 2.** Amend your Helix `languages.toml` file:
+  ```toml
+  [[language]]
+  name = "kcl"
+  scope = "source.k"
+  file-types = ["kcl", { glob = "*.k" } ]
+  roots = ["kcl.mod", "kcl.yaml"]
+  language-servers = ["kcl-lsp"]
+
+  [language-server.kcl-lsp]
+  command = "kcl-language-server"
+  ```
+- **Step 3.** Reopen Helix, create a KCL file, and begin your KCL journey!
+
