+To use this configuration layer, update custom configuration file with:
+
+```toml
+[[layers]]

+```
+## Features
+
+- syntax highlighting for `.fnl` files
+- repl support
+- code runner
+

+
+
+## Key bindings
+
+### Running current script
+
+To running a fennel file, you can press `SPC l r` to run current file without loss focus,
+and the result will be shown in a runner buffer.
+
+### Inferior REPL process

+Start a `fennel` inferior REPL process with `SPC l s i`.
+
+Send code to inferior process commands:

+| ------------ | ------------------------------------------------ |
+| `SPC l s b`  | send buffer and keep code buffer focused         |
+| `SPC l s l`  | send line and keep code buffer focused           |
+| `SPC l s s`  | send selection text and keep code buffer focused |
