+
+To create a new block, we need to provide:
+
+`1: group name`: the name of the group in which the custom block is placed
+
+`2: Block color`: Appearance color of the block
+
+`3: Block label`: Only letters, numbers, underscores are allowed
+
+`4: Block type`: Define the type of the block as `Value` (value), or `Execute` (execute)
+
+`5: Number of blocks`: Ability to add multiple blocks at the same time and save them to a `.m5b` file at the same time
+
+
+
+
+
+## Code-Parameter
+
+
+Click the `Add` option under `Parameter`, add a program property, enter the name displayed in the block, and select the property type. Enter the code contained in the custom block in the `Block Code` option box.
+
+[Click here to visit Github for more program API](https://github.com/m5stack/UIFlow-Code/wiki)
+
+
+
+When the attribute type of a custom block has constant or variable input, we can get these values in the code and perform further processing and operations.
+
+Example: Select the attribute type as `String` (string input). In this case, if we want to get the string input when using, just use `${Parameter name}` in the code. It is `${show_word}`. It should be noted that when there is a space in the block name, use ${} to get the space that needs to be replaced with the `_` underscore.
+
+
+
+## Save and Changes
+
+After editing the program, click `Download` to save.
+
+Click on `Open .m5b` to open the saved custom program for modification.
+
+
+
+
+## Using program block
+
+Open a custom block by clicking on the`Custom`option > `Open` ，in the block list.

+ UIFlow 程序块定制
+
+
+创建一个新的程序块，我们需要提供 :
+
+`1：分组名称`: 自定义程序块所放置在的分组名称
+
+`2：程序块颜色`: 程序块的外观颜色
+
+`3：程序块标签`: 只允许包含字母、数字、下划线
+
+`4：程序块类型`: 定义程序块的类型为`Value`(数值)，或是`Execute`(执行)
+
+`5：程序块数量`: 能够同时添加多个程序块，并同时保存到一个`.m5b`文件中
+
+
+
+
+
+## 程序块代码-传参
+
+
+点击`Parameter`下方的`Add`选项，添加一条程序属性，输入程序块所显示的名称，以及选择属性类型，在`Block Code`选项框中输入自定义程序块所包含的代码.
+
+[点击此处，访问Github获取更多程序API](https://github.com/m5stack/UIFlow-Code/wiki)
+
+
+
+当自定义程序块的属性类型带有常量或变量输入时，我们可以在代码中获取这些值，并进行进一步的处理和运算.
+
+例： 将属性类型选择为`String`(字符串输入)，此时在程序中，如果我们想要获得使用时所输入的字符串，只需要在代码中使用`${Parameter name}`，也就是`${show_word}`,需要注意的是，当程序块名称中带有空格时，在使用${}去获取需要使用`_`下划线对空格进行替代
+
+
+
+## 程序块保存-修改
+
+完成程序编辑后，点击`Download`进行保存
+
+点击`Open .m5b`，能够打开已保存的自定义程序进行修改
+
+
+
+
+## 使用程序块
+
+点击程序块列表中的`Custom`选项 > `Open` ，打开一个自定义程序块
