+To use a custom html file emccStep() accepts a shell_file_path option:
+```zig
+    const emcc_step = @import("zemscripten").emccStep(
+        b,
+        wasm,
+        .{

 Now you can use the provided Zig panic and log overrides in your wasm's root module and define the entry point that invoked by the js output of `emcc` (by default it looks for a symbol named `main`). For example:
 ```zig
 const std = @import("std");
