+
+## 💡 About
+
+</div>
+
+freegpt is a powerful javascript library you can use to get ChatGPT on your website, and its free!
+
+- Simple, just one function
+- Open-source, free
+- Easy-to-use
+- Lightweight (yet optimally performant)
+- No authentication, free for all
+- Unlimited GPT 3.5 Model
+
+<div id="importing">
+
+## ⚡ Importing the library
+
+</div>
+
+> **Note** _To always import the latest version (NOT recommended in production!) replace the versioned jsDelivr URL with: `https://cdn.jsdelivr.net/npm/@ashishagarwal2023/freegptjs`_
+
+## 💻 Usage
+
+```js
+(async () => {
+  let response = await gpt.ask("Explain variables in javascript");
+  console.log(response); // you got it!
+})();
+```
+
+There's literally nothing more coded. It's a reverse engineering of You.com API (which is completely free, I was shocked to see)
+
+## 🤖 Why client-side?
+
+You got it, I also got it. The route where I recieve the fetch in the library is protected by Cloudflare. Got it?
+
+> When I tried to get the response using NodeJS, it appeared that it gave HTML, and oh, there was Cloudflare security. I tried several web scrapers for NodeJS (and even tried python) but there was one paid, that I cannot afford and so this AJAX request still worked.
+
+> **Why we just care about the AJAX?** Listen, you can simply do your client's fetch requests using AJAX when the user comes to chat, and its simple when using pure HTML-JavaScript, so give it a try!
+
+> Generative Mode is **enabled**. This means GPT will not remember anything you tell it.
+
+### Why I just made it?
+
+There was a chatgptpy library for Python and several for NodeJS also. But I wanted to build a completely free one, so I made this.
+
+Give it a star if you want to help me keep it active. Follow me when?
+
+It depends on **You.com**'s API, however its reverse engineered, but it has no tokens/login or such.
+
+## 🤝Contributing
+
+You are welcome! I'm looking for some cool peoples to help me push this project further!
+
+> The API routes are given in plan.js, so read it if you would like to know how the API would work
+
+If you made a working webscraper and would like me to use it (Cloudflare Bypass), you are welcome, but remember I cannot afford a bit, sorry.
