Ecommerce Core includes an agent guide that helps developers research, plan, build, test, and document a new ecommerce connector app for Frappe and ERPNext.

The complete instructions are maintained in [`AGENTS.md`](https://github.com/aerele/ecommerce-core/blob/develop/AGENTS.md).

> Ecommerce Core remains provider-neutral. Provider authentication, API clients, data mappings, webhooks, and provider-specific sync
logic are created in a separate connector app. Shared features such as product mapping, inventory sync, warehouse mapping,
scheduling, and integration logging remain in Ecommerce Core.


## Demo

## Supported Development Tools

- **Codex** and **Cursor** automatically discover `AGENTS.md`.
- For **Claude Code**, explicitly ask it to read and follow `apps/payment_core/AGENTS.md`.

## Before You Start

Use a Frappe Bench containing:

- Frappe
- ERPNext
- Ecommerce Core
- A local development site for testing

Payment Core supports Frappe and ERPNext from `version-16` through `develop`.
