 Sick of installing packages just to archive a simple task? YDNAP is here to help!
 
-In the end of the day, you maybe don't need ramda, lodash, date-fns, or any other package to do simple tasks.
+In the end of the day, you maybe don't need Ramda, Lodash, date-fns, or any other package to do simple tasks.

+### CLI Options
+
+| Option        | Type    | Short | Default | Choices    | Description                                                                     |
+| ------------- | ------- | ----- | ------- | ---------- | ------------------------------------------------------------------------------- |
+| `--verbose`   | boolean | `-v`  | `false` | N/A        | Enables verbose mode for detailed logging.                                      |
+| `--extension` | string  | `-e`  | `js`    | `js`, `ts` | Specifies the file extension to use (`js` for JavaScript, `ts` for TypeScript). |
+| `--template`  | string  | `-t`  | N/A     | N/A        | Specifies the template folder to use.                                           |
+| `--repo`      | string  | `-r`  | N/A     | N/A        | (Optional) Specifies the repository URL to fetch templates from.                |
+| `--output`    | string  | `-o`  | N/A     | N/A        | (Optional) Specifies the output directory for generated files.                  |
+
+## Installation
+
+You can install YDNAP globally using npm:
+
+```bash
+npm install -g ydnap
+```
+
+Or you can use it without installing it by using npx:
+
+```bash
+npx ydnap
+```
 
 ## Usage
 
-### Using with npx
+You can use YDNAP and create files using our [templates](https://github.com/GuildaDev/ydnap-templates), or you can create your own templates (or share them with your friiiiends).
+
+To use our template, you can run:
+
+```bash
+ydnap -t sum # or npx ydnap -t sum
+```
+
+by default, we will always find the javascript file.
+
+you can also specify the typescript file:
 
 ```bash
-npx ydnap -t sum
+ydnap -t sum -l ts # or npx ydnap -t sum -l ts
 ```
 
+Using you repository (eg https://github.com/alexcastrodev/ydnap-example/tree/main/src/even)
+
+```bash
+ydnap -u alexcastrodev/ydnap-example -t even
+```
+
+> **Note**  
+> It's mandatory that the `-t` (template) argument points to a folder, and the file inside the folder should be named `index.ts` or `index.js`.
+
 ## Drawbacks
 
 YDNAP is designed to solve small tasks, like navigating through objects with JavaScript or TypeScript (without needing the full weight of libraries like Ramda or Lodash), or creating a useDebounceCallback for React without installing an entire hooks library.
