+# Agentic Autogen
+
+[![1-click-deploy](https://raw.githubusercontent.com/DefangLabs/defang-assets/main/Logos/Buttons/SVG/deploy-with-defang.svg)](https://portal.defang.dev/redirect?url=https%3A%2F%2Fgithub.com%2Fnew%3Ftemplate_name%3Dsample-agentic-autogen-template%26template_owner%3DDefangSamples)
+
+This sample shows an agentic Autogen application using Mistral and FastAPI, deployed with Defang. For demonstration purposes, it will require a Mistral API key (see [Configuration](#configuration) for more details). However, you are free to modify it to use a different LLM, say the Defang OpenAI Access Gateway service, as an alternative. Note that the Vite React frontend is served through the FastAPI backend so that they can be treated as one service in production.
+ 
+## Prerequisites
+
+1. Download [Defang CLI](https://github.com/DefangLabs/defang)
+2. (Optional) If you are using [Defang BYOC](https://docs.defang.io/docs/concepts/defang-byoc) authenticate with your cloud provider account
+3. (Optional for local development) [Docker CLI](https://docs.docker.com/engine/install/)
+
+## Development
+
+To run the application locally, you can use the following command:
+
+```bash
+docker compose up --build
+```
+
+## Configuration
+
+For this sample, you will need to provide the following [configuration](https://docs.defang.io/docs/concepts/configuration): 
+
+> Note that if you are using the 1-click deploy option, you can set these values as secrets in your GitHub repository and the action will automatically deploy them for you.
+
+### `MISTRAL_API_KEY`
+An API key to access the [MistralAI] LLM.
+```bash
+defang config set MISTRAL_API_KEY
+```
+
+## Deployment
+
+> [!NOTE]
+> Download [Defang CLI](https://github.com/DefangLabs/defang)
+
+### Defang Playground
+
+Deploy your application to the Defang Playground by opening up your terminal and typing:
+```bash
+defang compose up
+```
+
+### BYOC
+
+If you want to deploy to your own cloud account, you can [use Defang BYOC](https://docs.defang.io/docs/tutorials/deploy-to-your-cloud).
