-# freelance_invoice
+# Freelance Invoice
+
+is a simple command line tool to generate invoices for freelance work. It uses a simple template system based
+on `jinja2` to generate the
+invoice in HTML and then converts it to a PDF using `xhtml2pdf`.
+
+## inatallation
+
+Use python venv:
+
+```bash
+python -m venv venv
+source venv/bin/activate
+``` 
+
+Install the requirements:
+
+```bash
+pip install -r requirements.txt
+```
+
+## usage
+
+There are two yaml files describing your invoice:
+
+- `invoice.yaml` contains the invoice data
+- `envelope.yaml` contains the address data of the sender and the recipient
+
+The invoice data is read from the `invoice.yaml` file and the address data is read from the `envelope.yaml` file. The
+invoice data is then used to fill in the invoice template and the address data is used to fill in the address fields of
+the invoice.
+
+Some data are globaly available from the envelope template. Some of them can be overriden by the invoice template.
+
+invoice.yaml - The Name of the invoice file is used as the invoice number but you are free to override it in the
+invoice.yaml file.
+
+```yaml
+Id: RG004712 # overrides the file name as invlice Number
+CustomerId: KD01234 # The customer id is used to identify the customer and is beeing looked up in the envelope.yaml file.
+InvoiceDate: 2023-12-23 # The date of the invoice. If not set the current date is used.
+
+Positions:
+  - Title: "Zuckerwatte fressen Ganz besonders langer Text"
+    SubTitle: "Leistungszeitraum: 11/2022"
+    PricePerUnit: 100 # The price per unit is taken from the envelope.yaml file using the customer id but can be overriden here.
+    Quantity: 100
+
+  - Title: "Aschlecken"
+    SubTitle: "Leistungszeitraum: 11/2022"
+    PricePerUnit: 99.99

+
+  - Title: "Aschkriechen"
+    SubTitle: "Leistungszeitraum: 10/2022"
+    PricePerUnit: 77.88
+    Quantity: 3

+
+```yaml
+AddressContent:
+  # AddressBoxSender is is used as the sender address in the letter head inside the address windows.
+  AddressBoxSender: "Abs.: Torsten Ueberschar - Pfarrweg 1 - 57439 Attendorn"
