+# Invoice-Extractor
+This is a purpose-built project to extract the tabluar data from Dutch KPN Mobile invoices.
+It is heavily relying on the [PDFQuery](https://github.com/jcushman/pdfquery) package.
+
+## Compatibility
+This package has been tested on invoices dating from 2016 until 2019, but will probably work with older and more recent invoices.
+
+## Installation
+At this moment this package does not exist in PyPI, and has to be put into the python package directory manually. For windows this is usually `C:Program Files (x86)\Python<version>\Lib\`
+
+## Usage
+
+It is possible to extract the data from just one pdf file, or a directory containing compatable pdf files.
+
+### Usage example
+```python3
+import invoice_extractor
+
+pdf_file = <somefilepath>
+pfd_directory = <somefilepath>
+output_directory = <somepath>
+
+
+invoice_extractor.extract(pfd_file, output_directory)
+invoice_extractor.extract(pfd_directory, output_directory)
+```
