-This gem provides FoodsoftArticleImport integration for Ruby on Rails and allows to parse avariety of files containing article information. These article information are standardized or customly declared. Possible File Ending are: .bnn, .BNN, .csv, .CSV . It relies on [roo](https://github.com/roo-rb/roo) to read and parse the data
+This gem provides FoodsoftArticleImport integration for Ruby on Rails and allows to parse a variety of files containing article information.

 ## Getting started
-TODO: add bnn codes, explain how to add bnn codes
+This is a very simple gem that can be used to extract data from files in the formats .bnn, .xml and .csv.
-TODO: review GNU License
+Given one of the aforementioned files, the gem returns information.
 
-For correct import of bnn files, please ensure the correct language setting. Your foodsoft account has to be settings set to german if you want to import articles from file.
+example for foodsoft file:
-To set this is imcrucial for guaranteeing the correct format of article prices.

+
+Information about Manufacturer, article category, tax and deposit are conveyed through "bnn codes".
+A "bnn code" is a mapping of some abbreviation or number to the relevant data.
+The data for suppliers lies at DataNatuRe and we just have a list of some mappings.
+Much more codes are needed to make this gem more powerfull. Maybe an xml api to DataNatuRe can be implemented in the futurepossibility.
+The list used in this gem is not complete, since it needs data from all manufacturers.
+If your local foodcoop posesses keys for article mapping, it is possible to use ypour custom code mapping.
+
+You can extend it for your local foodcoop, if you create a custom_codes.yml, and put it in your root folder. 
+
+extracted article attributes will be:
+
+* name: article name from bnn
+* order_number: order number from bnn
+* note: extra note from bnn
+* manufacturer: e.g. ALN -> AL Naturkost Handels GmbH"
+* origin: e.g. "GB"
+* article_category: e.g. "0202": Sauermilchprodukte
+* unit: 
+* price:
+* tax: e.g. "1" -> "7.0"
+* unit_quantity:
+* deposit: e.g. "930190" -> 0.08
+
