+# django-SHOP
+
+**Django-SHOP** aims to be a the easy, fun and fast e-commerce counterpart to
+[django-CMS](https://www.django-cms.org/).

+
+## Build the database model out of the product's properties – not vice versa
+
+Most e-commerce systems are shipped with a predefined database model for products. But products can
+vary a lot, and it simply is impossible to create a model which fits for all of them. This is
+esspecially true for products with a hierarchy of variants. In many popular e-commerce platforms,
+you either have far too many attributes per product, and/or the really required attributes are
+missing.
+
+In **django-SHOP** implementations, the product models reflect their pysical properties making it
+possible to create complete and deep hierarchies of variations, but without having to fiddle with
+unneeded properties. It furthermore avoids the need for an
+[Entity Attribute Value Model](https://en.wikipedia.org/wiki/Entity–attribute–value_model), which
+is considered a database anti-pattern, because it produces far too many table joins, when filtering
+by property.
+
+
+## Don't build pages using hard-coded templates – compose them
+
+With the advent of frameworks, such as Angular, React, Vue and Aurelia, building web-applications
+shifted from a page-centric to a component-based approach.
+
+In **django-SHOP**, you are in full control over the page's layout, since all components are
+encapsulated and independent from each other. This means that instead of adopting the Catalog, Cart,
+Checkout and Order pages, use the **django-CMS** plugin system to compose everything required for
+those pages.
+
+
+## All Views are either HTML or RESTful services
+
+Browser based navigation is important, but nowadays it's only one of many channels clients use to
+communicate with a web-server. Consider Single Page Applications or other native clients, where we
+use RESTful APIs instead of pure HTTP.
+
+This substantially reduces the payload having to be transferred. It furthermore gives the client a
+smoother user experience, since only the content has to be updated, rather than having to do full
+page reloads.
+
+
+## Programmable cart modifiers
+
+During checkout, taxes have to be applied or attributed. Depending on the shipping destination, the
+product group and other factors, this computation can either be simple or quite demanding.
+**Django-SHOP** offers a pluggable interface to create modifiers which calculate the cart's totals,
+taxes and other costs.
+
+This same interface can be extended to compute the weight and shipping costs. It also can be used
+for subtracting discounts or to add additional charges. 
+
+
+## Programmable workflow for fulfilment and delivery
+
+Fulfilling and shipping orders probably requires the most individual adaption for an e-commerce business. 
+**Django-SHOP** offers a programmable interface for order by using a finite
+state machine to adopt the workflow. Each order may have several states, but the only actions
+allowed are limited to explicitly defined state transitions.
+
+
+## It's modular
+
+Whenever possible, extra features should be added by third party libraries. This implies that
+**django-SHOP** aims to provide an API, which allows merchants to add every feature they desire.
+
+Currently there are third party libraries for several Payment Service Providers, such as
+[PayPal](https://developer.paypal.com/docs/api/overview/), [Stripe](https://stripe.com/docs/api),
+[BS-PayOne](https://www.bspayone.com/DE/en) and [Viveum](https://www.viveum.com/?lang=en).
+An open interface allows you to add any other provider.
+
+Shipping Service Providers may be added as third party library as well. With
+[SendCloud](https://docs.sendcloud.sc/), ship your orders using one or more parcel services
+available for your region.
+
+
+## Start by building your own demo
+
+Instead of providing an accessible online demo, **django-SHOP** can be set up in less than three
+minutes and preconfigured to your needs. Having access to the product models, you can immediatly
+start to play arround with, rename, and modify them to reflect the properties of your products.
+This is the easiest way to get a shop up and running out of the box with the flexibility of a
+website that you could have built from scratch.
+
+If you want to start with a fresh demo, please use the prepared
+[Cookiecutter template for django-SHOP](https://github.com/awesto/cookiecutter-django-shop)
+and follow the instructions. 
+
+
+## Audience of django-SHOP users
+
+Specifically, we aim at providing a clean, modular and Pythonic/Djangonic implementation of an
+e-commerce framework, that a moderately experienced Django developer should be able to pick up
+and run easily. Pure Django models are used to describe each product type, and so the Django admin
+can be used to build a minimalistic editor for each of them.
+
+
+## Consultancy
+
+We provide full consultancy support and are available for building complete e-commerce systems based
+on **django-SHOP**. Please contact [email protected] for further questions.
