 # LLM React App Javascript Template
 
-## What is a LLM React App Javascript Template?
+## What is an LLM React Node App Javascript Template?
 
-This a template project for a simple chat app connected to a Large Language Model (LLM). This is built on top of [the React template app from nano-react-app](https://github.com/nano-react-app/template-js). To connect the React app to an LLM, a Node server has been added to the project.
+This template is an example project for a simple Large Language Model (LLM) application built on top of React and Node. This template was built on top of [the React template app from nano-react-app](https://github.com/nano-react-app/template-js) and updated with a Node server that uses [LangChain.js](https://github.com/hwchase17/langchainjs) to connect to supported large language models, e.g. OpenAI and Hugging Face. Use this template to easily build and run an LLM app, like the screenshot below:

 These are the available commands:
 
-- `npm start-server` — This will start a development node backend server with a default port of `3100`.
-- `npm start` — This will start a development server for the react frontend app with a default port of `5173`.
-- `npm run build` — This will output a production build in the `dist` directory.
-- `npm run preview` — This will run the production build locally with a default port of `5173` (this will not work if you haven't generated the production build yet).

-## Adding styles
-
-You can use CSS files with simple ES2015 `import` statements anywhere in your Javascript:
-
-```js
-import "./index.css";
-```

-## Babel transforms
-
-The Babel preset [babel-preset-nano-react-app](https://github.com/nano-react-app/babel-preset-nano-react-app) is used to support the same transforms that Create React App supports.
-
-The Babel configuration lives inside `package.json` and will override an external `.babelrc` file, so if you want to use `.babelrc` remember to delete the `babel` property inside `package.json`.

-## Deploy to GitHub Pages
-
-You can also deploy your project using GitHub pages.
-First install the `gh-pages` [package](https://github.com/tschaub/gh-pages):
-
-`npm i -D gh-pages`
-
-Use the following scripts for deployment:
-
-```js
-"scripts": {
-  "start": "vite",
-  "build": "vite build",
-  "predeploy": "rm -rf dist && vite build",
-  "deploy": "gh-pages -d dist"
-},
-```
-
-Then follow the normal procedure in GitHub Pages and select the `gh-pages` branch.
