 用法：march <scene>
-例：march sphere(1) cam(4).pos(-5).lookat(0) 
\ No newline at end of file
+例：march sphere(1).color(red) box(0.5, 2.0, 0.5).pos(0, 0, 0) cam(0.5).pos(-5).lookat(0)
+
+# 主要语法
+<scene> ::= <scene> "." <op>
+        |   <obj>
+
+<obj>   ::= <obj_ty>
+        |   <obj_ty> "(" <args> ")"
+
+<op>    ::= <op_ty>
+        |   <op_ty> "(" <args> ")"
+
+<args>  ::= <args> "," <arg>
+        |   <arg>
+
+其中 obj_ty、op_ty 分别为物体类型（如 cube、sphere、torus 等）与变换类型（如 pos、rot）。
+
+# 特殊说明
+<op_ty> 不包含 scale，因为本工具基于 SDF 渲染，非正交的变换会破坏 SDF 的性质。
