+### Template Syntax
+
+The template syntax follows
[etpl](https://github.com/ecomfe/etpl/blob/master/doc/syntax.md) (but use `{{
}}` rather than `<!-- -->` as the interpolate tags).
+> A syntax highlight tool:
[etpl-vscode](https://marketplace.visualstudio.com/items?itemName=yibuyisheng.etpl-vscode)
+
+Summary of the commonly used syntax:
+```template
+VARIABLE:
+some text ${someVariable} some text
+
+
+IF ELSE:
+{{ if: ${number1} > 0 }}
+some text xxx
+{{ elif: ${string1} === 'abc' }}
+some text yyy
+{{ else }}
+some text zzz
+{{ /if }}
+
+
+FOR LOOP:
+{{ for: ${persons} as ${person}, ${index} }}
+some text ${index}: ${person.name}
+{{ /for }}
+
+
+TARGET (DEFINE A BLOCK):
+{{ target: a_predefined_block_name_1 }}
+The input varA is ${varA}
+The input varB is ${varB}
+The input varC is ${varC}
+some other text xxx
+(The close target can be omitted, but not recommended.)
+{{ /target }}
+
+
+USE (USE A BLOCK):
+{{ use: a_predefined_block_name_1(
+ varA = ${myVarX},
+ varB = 123,
+ varC = 'some string'
+)}}
+{{ use: a_predefined_block_name_2 }}
