+## Project Overview
+
+Pchelpcrm is a CRM for handling service requests (orders) of a private service professional: computer help, home repairs, furniture assembly, plumbing, electrical work, etc. The domain is deliberately generic: any "client calls, a job gets done" business fits. Currently used personally by the author, so keep it simple.
+
+Domain entities:
+
+- **User** — the owner of the personal account who works in the CRM (a PocketBase auth record). Everything below belongs to a user and must be isolated per user (API rules).
+- **Client** — a customer of the user. A separate entity, not a user.
+- **Request** — a service request (order). Belongs to exactly one client; one client can have many requests.
+- **Category** — a request category. Dynamic: created and edited by the user, never hardcoded in code or enums.
+
+Auth: PocketBase auth collection, login by email + password.
+
+Stack: Angular (see rules below) + PocketBase (`pocketbase/pb_migrations/` holds the schema) + pnpm. Add other libraries (e.g. a UI component library) only when really needed.
+
+Delivery plan: after the first release the app ships as ONE Docker container (Angular app + PocketBase together, no docker-compose) deployable to a production server. Do not design anything that requires multiple containers.
+
 ## TypeScript Best Practices
 
 - Use strict type checking

 # Pchelpcrm
 
-This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version 22.2.3.
+A CRM for handling service requests (orders) of a private service professional: computer help, home repairs, furniture assembly, plumbing, electrical work and similar jobs. The domain is generic, so any business where a client asks for a job to be done fits.
+
+## Concepts
+
+- **User** — the account owner who works in the CRM. Signs in with email and password (PocketBase auth). Data of each user is isolated from others.
+- **Client** — a customer of the user.
+- **Request** — a service request (order). Belongs to one client; a client can have many requests.
+- **Category** — a request category. Dynamic: created and edited by the user.
+
+## Stack
+
+- [Angular](https://angular.dev/) — frontend, generated with [Angular CLI](https://github.com/angular/angular-cli) 22.2.3
+- [PocketBase](https://pocketbase.io/) — backend, database and authentication
+- [pnpm](https://pnpm.io/) — package manager
+
+## Distribution
+
+After the first release the application will be shipped as a single Docker container (the app and PocketBase together, no docker-compose) that can be deployed to a production server.
