+## Features
+
+- [Next.js](https://nextjs.org) App Router
+- React Server Components (RSCs), Suspense, and Server Actions
+- [Vercel AI SDK](https://sdk.vercel.ai/docs) for streaming chat UI
+- Support for OpenAI (default), Anthropic, Hugging Face, or custom AI chat models and/or LangChain
+- Edge runtime-ready
+- [shadcn/ui](https://ui.shadcn.com)
+  - Styling with [Tailwind CSS](https://tailwindcss.com)
+  - [Radix UI](https://radix-ui.com) for headless component primitives
+  - Icons from [Phosphor Icons](https://phosphoricons.com)
+- Chat History, rate limiting, and session storage with [Vercel KV](https://vercel.com/storage/kv)
+- [NextAuth.js](https://github.com/nextauthjs/next-auth) for authentication
+
+## Model Providers
+
+This template ships with OpenAI `gpt-3.5-turbo` as the default. However, thanks to the [Vercel AI SDK](https://sdk.vercel.ai/docs), you can switch LLM providers to [Anthropic](https://anthropic.com), [Hugging Face](https://huggingface.co), or using [LangChain](https://js.langchain.com) with just a few lines of code.
+
+## Deploy Your Own
+
+You can deploy your own version of the Next.js AI Chatbot to Vercel with one click:
+
+[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/clone?demo-title=Next.js+Chat&demo-description=A+full-featured%2C+hackable+Next.js+AI+chatbot+built+by+Vercel+Labs&demo-url=https%3A%2F%2Fchat.vercel.ai%2F&demo-image=%2F%2Fimages.ctfassets.net%2Fe5382hct74si%2F4aVPvWuTmBvzM5cEdRdqeW%2F4234f9baf160f68ffb385a43c3527645%2FCleanShot_2023-06-16_at_17.09.21.png&project-name=Next.js+Chat&repository-name=nextjs-chat&repository-url=https%3A%2F%2Fgithub.com%2Fvercel-labs%2Fai-chatbot&from=templates&skippable-integrations=1&env=OPENAI_API_KEY%2CAUTH_GITHUB_ID%2CAUTH_GITHUB_SECRET%2CAUTH_SECRET&envDescription=How+to+get+these+env+vars&envLink=https%3A%2F%2Fgithub.com%2Fvercel-labs%2Fai-chatbot%2Fblob%2Fmain%2F.env.example&teamCreateStatus=hidden&stores=[{"type":"kv"}])
+
+## Creating a KV Database Instance
+
+Follow the steps outlined in the [quick start guide](https://vercel.com/docs/storage/vercel-kv/quickstart#create-a-kv-database) provided by Vercel. This guide will assist you in creating and configuring your KV database instance on Vercel, enabling your application to interact with it.
+
+Remember to update your environment variables (`KV_URL`, `KV_REST_API_URL`, `KV_REST_API_TOKEN`, `KV_REST_API_READ_ONLY_TOKEN`) in the `.env` file with the appropriate credentials provided during the KV database setup.
+
+
+## Running locally
+
+You will need to use the environment variables [defined in `.env.example`](.env.example) to run Next.js AI Chatbot. It's recommended you use [Vercel Environment Variables](https://vercel.com/docs/concepts/projects/environment-variables) for this, but a `.env` file is all that is necessary.
+
+> Note: You should not commit your `.env` file or it will expose secrets that will allow others to control access to your various OpenAI and authentication provider accounts.
+
+1. Install Vercel CLI: `npm i -g vercel`
+2. Link local instance with Vercel and GitHub accounts (creates `.vercel` directory): `vercel link`
+3. Download your environment variables: `vercel env pull`
+
+```bash
+pnpm install
+pnpm dev
+```
+
+Your app template should now be running on [localhost:3000](http://localhost:3000/).
