-# Welcome to React Router!
+# @documenso/remix
 
-A modern, production-ready template for building full-stack React applications using React Router.
+The main Documenso web application. Built with [React Router v7](https://reactrouter.com/) and served by a [Hono](https://hono.dev/) server.
 
-[![Open in StackBlitz](https://developer.stackblitz.com/img/open_in_stackblitz.svg)](https://stackblitz.com/github/remix-run/react-router-templates/tree/main/default)
+This package is part of the Documenso monorepo and is not meant to be run standalone. Use the root scripts instead.
 
-## Features
-
-- 🚀 Server-side rendering
-- ⚡️ Hot Module Replacement (HMR)
-- 📦 Asset bundling and optimization
-- 🔄 Data loading and mutations
-- 🔒 TypeScript by default
-- 🎉 TailwindCSS for styling
-- 📖 [React Router docs](https://reactrouter.com/)
-
-## Getting Started
-
-### Installation
-
-Install the dependencies:
-
-```bash
-npm install
-```
-
-### Development
-
-Start the development server with HMR:
+- Local development: see the [root README](../../README.md) and the [Local Development docs](https://docs.documenso.com/docs/developers/local-development).
+- Self-hosting and deployment: see the [Self-Hosting docs](https://docs.documenso.com/docs/self-hosting).
+- Architecture overview: see [ARCHITECTURE.md](../../ARCHITECTURE.md).
 
 ```bash
+# From the monorepo root
 npm run dev
 ```
-
-Your application will be available at `http://localhost:5173`.
-
-## Building for Production
-
-Create a production build:
-
-```bash
-npm run build
-```
-
-## Deployment
-
-### Docker Deployment
-
-This template includes three Dockerfiles optimized for different package managers:
-
-- `Dockerfile` - for npm
-- `Dockerfile.pnpm` - for pnpm
-- `Dockerfile.bun` - for bun
-
-To build and run using Docker:
-
-```bash
-# For npm
-docker build -t my-app .
-
-# For pnpm
-docker build -f Dockerfile.pnpm -t my-app .
-
-# For bun
-docker build -f Dockerfile.bun -t my-app .
-
-# Run the container
-docker run -p 3000:3000 my-app
-```
-
-The containerized application can be deployed to any platform that supports Docker, including:
-
-- AWS ECS
-- Google Cloud Run
-- Azure Container Apps
-- Digital Ocean App Platform
-- Fly.io
-- Railway
-
-### DIY Deployment
-
-If you're familiar with deploying Node applications, the built-in app server is production-ready.
-
-Make sure to deploy the output of `npm run build`
-

-│   ├── client/    # Static assets
-│   └── server/    # Server-side code
-```
-
-## Styling
-
-This template comes with [Tailwind CSS](https://tailwindcss.com/) already configured for a simple default starting experience. You can use whatever CSS framework you prefer.
