+## 模块简介
+
+这一模块为在 SpaceVim 中进行 crystal 开发提供了支持。
+
+## 启用模块
+
+可通过在配置文件内加入如下配置来启用该模块：
+
+```toml
+[[layers]]
+  name = "lang#crystal"
+```
+
+## 快捷键
+
+### 交互式编程
+
+启动 `icr` 交互进程，快捷键为： `SPC l s i`。
+
+将代码传输给 REPL 进程执行：
+
+| 快捷键      | 功能描述                |
+| ----------- | ----------------------- |
+| `SPC l s b` | 发送整个文件内容至 REPL |
+| `SPC l s l` | 发送当前行内容至 REPL   |
+| `SPC l s s` | 发送已选中的内容至 REPL |
+
+### 运行当前脚本
+
+在编辑 crystal 文件时，可通过快捷键 `SPC l r` 快速异步运行当前文件，运行结果会展示在一个独立的执行窗口内。

+## Description
+
+This layer is for crystal development.
+
+## Install
+
+To use this configuration layer, update custom configuration file with:
+
+```toml
+[[layers]]
+  name = "lang#crystal"
+```
+
+To use REPL for crystal, you need to install [icr](https://github.com/crystal-community/icr).
+
+## Features
+
+- repl support
+- code runner
+
+## Key bindings
+
+### Running current script
+
+To running a crystal 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 `icr` inferior REPL process with `SPC l s i`.
+
+Send code to inferior process commands:
