 # ChatGPT for VSCode
 
-This is a VSCode extension that allows you to use ChatGPT right within VSCode.
+This Visual Studio Code extension allows you to use the [unofficial ChatGPT API](https://github.com/transitive-bullshit/chatgpt-api) to generate natural language responses from OpenAI's [ChatGPT](https://chat.openai.com/chat) to your questions, right within the editor.
 
-**Warning:** Right now, this is more of a proof of concept!
+## Features
+- Ask general questions or use code snippets from the editor to query ChatGPT
+- View its responses in a panel next to the editor
+- Insert code snippets from the AI's response into the active editor
 
-## How it works
+## Getting started
 
-The extension makes use of this [ChatGPT package](https://github.com/transitive-bullshit/chatgpt-api), which uses Playwright/a headless chrome in order to login and communicate with ChatGPT.
+To use this extension, you will need to authenticate with a valid session token from ChatGPT. To get a session token:
 
-In order to use this with VSCode, it's best to run the extension in debug mode once.
-On the initial start, you will need to authenticate with OpenAI - this requires you to login via the headless Chrome.
+1. Go to https://chat.openai.com/chat and log in or sign up.
+2. Open the developer tools in your browser.
+3. Go to the `Application` tab and open the `Cookies` section.
+4. Copy the value for `__Secure-next-auth.session-token` and save it.
 
-When you are successfully authenticated, you can turn on headless mode so that the browser won't be visible.
+Once you have obtained a session token, you can configure the extension to use it by adding the following line to your Visual Studio Code settings:
+
+```
+"chatgpt.SESSION_TOKEN": "<your session token here>"
+```
+
+Extensions should then be restarted in order to work.
+
+
+## Using the Extension
+
+
+To use the extension, open a text editor in Visual Studio Code and open the ChatGPT panel by clicking on the ChatGPT icon in the sidebar. This will open a panel with an input field where you can enter your prompt or question. By clicking enter, it will be sent to ChatGPT. Its response will be displayed below the input field in the sidebar (note that it may take some time for it to be calculated).
+
+You can also select a code snippet in the editor and then enter a prompt in the side panel. The selected code will be automatically appended to your query when it is sent to the AI. This can be useful for generating code snippets or getting explanations for specific pieces of code.
+
+To insert a code snippet from the AI's response into the editor, simply click on the code block in the panel. The code will be automatically inserted at the cursor position in the active editor.
+
+
+## Current Issues
+
+After installing the dependencies, you may need to modify the `exports` property of `node_modules\chatgpt\package.json` by moving the `default` property to be the last one in the object (`"exports": { "import": "./build/index.js", "types": "./build/index.d.ts", "default": "./build/index.js" },`)
+
+Please note that this extension is currently a proof of concept and may have some limitations or bugs. We welcome feedback and contributions to improve the extension.
