+
+## Build an AI Drug Assistant with Pipes — ⌘ Langbase
+
+This chatbot is built by using an AI Pipe on Langbase, it works with 30+ LLMs (OpenAI, Gemini, Mistral, Llama, Gemma, etc), any Data (10M+ context with Memory sets), and any Framework (standard web API you can use with any software).
+
+Check out the live demo [here][demo].
+
+## Features
+
+- 💬 [AI Drug Assistant][demo] — Built with an [AI Pipe on ⌘ Langbase][pipe]
+- ⚡️ Streaming — Real-time chat experience with streamed responses
+- 🗣️ Q/A — Ask questions and get pre-defined answers with your preferred AI model and tone
+- 🔋 Responsive and open source — Works on all devices and platforms
+
+## Learn more
+
+1. Check the [AI Drug Assistant on ⌘ Langbase][pipe]
+2. Read the [source code on GitHub][gh] for this example
+3. Go through Documentaion: [Pipe Quick Start][qs]
+4. Learn more about [Pipes & Memory features on ⌘ Langbase][docs]
+
+## Get started
+
+Let's get started with the project:
+
+To get started with Langbase, you'll need to [create a free personal account on Langbase.com][signup] and verify your email address. _Done? Cool, cool!_
+
+1. Fork the [AI Drug Assistant][pipe] Pipe on ⌘ Langbase.
+2. Go to the API tab to copy the Pipe's API key (to be used on server-side only).
+3. Download the example project folder from [here][download] or clone the reppository.
+4. `cd` into the project directory and open it in your code editor.
+5. Duplicate the `.env.example` file in this project and rename it to `.env.local`.
+6. Add the following environment variables (.env.local):
+```
+    # Replace `PIPE_API_KEY` with the copied API key.
+    NEXT_LB_PIPE_API_KEY="PIPE_API_KEY"
+```    
+7. Issue the following in your CLI:
+```
+    # Install the dependencies using the following command:
+    npm install
+
+    # Run the project using the following command:
+    npm run dev
+```
+
+8. Your app template should now be running on [localhost:3000][local].
+
+> NOTE:
+> This is a Next.js project, so you can build and deploy it to any platform of your choice, like Vercel, Netlify, Cloudflare, etc.
