-# Payload Blank Template
+# Training App
 
-This template comes configured with the bare minimum to get started on anything you need.
+A client-facing training app built with [Payload CMS](https://payloadcms.com) and Next.js. Coaches manage workout plans in the Payload admin panel; clients log their sets through a mobile-friendly web interface.
 
-## Quick start
+## Features
 
-This template can be deployed directly from our Cloud hosting and it will setup MongoDB and cloud S3 object storage for media.
+- Workout plan hierarchy: Plan → Microcycle → Workout → Exercise
+- Per-set logging with flexible tracking types (reps, weight, time, RIR, etc.)
+- Polish and English UI (next-intl)
+- Client authentication via Payload
 
-## Quick Start - local setup
+## Tech stack
 
-To spin up this template locally, follow these steps:
+- **Next.js** (App Router)
+- **Payload CMS** — content and auth
+- **PostgreSQL** via `@payloadcms/db-postgres`
+- **Tailwind CSS**
+- **next-intl** — i18n (Polish / English)
 
-### Clone
+## Getting started
 
-After you click the `Deploy` button above, you'll want to have standalone copy of this repo on your machine. If you've already cloned this repo, skip to [Development](#development).
+### Requirements
 
-### Development
+- Node.js 18+
+- PostgreSQL database
 
-1. First [clone the repo](#clone) if you have not done so already
-2. `cd my-project && cp .env.example .env` to copy the example environment variables. You'll need to add the `MONGODB_URL` from your Cloud project to your `.env` if you want to use S3 storage and the MongoDB database that was created for you.
+### Setup
 
-3. `pnpm install && pnpm dev` to install dependencies and start the dev server
-4. open `http://localhost:3000` to open the app in your browser
+```bash
+git clone https://github.com/your-username/training-app
+cd training-app
+npm install
+cp .env.example .env
+```
 
-That's it! Changes made in `./src` will be reflected in your app. Follow the on-screen instructions to login and create your first admin user. Then check out [Production](#production) once you're ready to build and serve your app, and [Deployment](#deployment) when you're ready to go live.
+Edit `.env`:
 
-#### Docker (Optional)
+```env
+DATABASE_URL=postgresql://user:password@localhost:5432/training_app
+PAYLOAD_SECRET=your-long-random-secret-here
+```
 
-If you prefer to use Docker for local development instead of a local MongoDB instance, the provided docker-compose.yml file can be used.
+### Run
 
-To do so, follow these steps:
+```bash
+npm run dev
+```
 
-- Modify the `MONGODB_URL` in your `.env` file to `mongodb://127.0.0.1/<dbname>`
-- Modify the `docker-compose.yml` file's `MONGODB_URL` to match the above `<dbname>`
-- Run `docker-compose up` to start the database, optionally pass `-d` to run in the background.
+The app is available at `http://localhost:3000`.
+The Payload admin panel is at `http://localhost:3000/admin`.
 
-## How it works
+### First-time setup
 
-The Payload config is tailored specifically to the needs of most websites. It is pre-configured in the following ways:
+1. Open `/admin` and create your first user account (becomes the super-admin)
+2. Create a **Client** collection record for each athlete
+3. Build a **Plan** and assign it to the client
+4. The client logs in at `/` using their email and password set in the admin
 
-### Collections
+## Project structure
 
-See the [Collections](https://payloadcms.com/docs/configuration/collections) docs for details on how to extend this functionality.

-- #### Users (Authentication)
+## License
 
-  Users are auth-enabled collections that have access to the admin panel.
-
-  For additional help, see the official [Auth Example](https://github.com/payloadcms/payload/tree/main/examples/auth) or the [Authentication](https://payloadcms.com/docs/authentication/overview#authentication-overview) docs.
-
-- #### Media
-
-  This is the uploads enabled collection. It features pre-configured sizes, focal point and manual resizing to help you manage your pictures.
-
-### Docker
-
-Alternatively, you can use [Docker](https://www.docker.com) to spin up this template locally. To do so, follow these steps:
-
-1. Follow [steps 1 and 2 from above](#development), the docker-compose file will automatically use the `.env` file in your project root
-1. Next run `docker-compose up`
-1. Follow [steps 4 and 5 from above](#development) to login and create your first admin user
-
-That's it! The Docker instance will help you get up and running quickly while also standardizing the development environment across your teams.
