From now on, whenever you run `tsc` command, your `typia` function call statements would be transformed to the optimal operation codes in the compiled JavaScript files.

+Instead you should utilise the generation mode. 
 
 Install `typia` through `npm install` command, and run `typia generate` command. Then, generator of `typia` reads your TypeScript codes of `--input`, and writes transformed TypeScript files into the `--output` directory, like below.
 
+For clarification, the input directory should contain one or more TypeScript files which define how you want to verify your associated type assertions. Commonly you will import your TypeScript type, then export a function which validates that type. See below.

 If you want to specify other TypeScript project file instead of `tsconfig.json`, you can use `--project` option.
