+## Usage
+
+Use [`VatchexGreece.new/4`](https://hexdocs.pm/vatchex_greece/VatchexGreece.html#new/4) with the target VAT ID plus your GSIS SOAP web service username, password, and source VAT ID associated with your authentication username and password (it's a legal requirement). This defines a clean new `%Results{}` struct containing the filled-in `%Auth{}` struct and the prepared `%GSISdata{}` struct. The `%Results{}` struct and its contents will be progressively filled in by the function calls within [`VatchexGreece.get/1`](https://hexdocs.pm/vatchex_greece/VatchexGreece.html#get/1).
+
+## Improvements since v0.6.0
+
+* Now compatible with the `RgWsPublic2` SOAP web service (new since 2023-04-20).
+* Now possible to make SOAP API calls using different credentials in `%Auth{}` structs, e.g. for multi-tenant setups.
+* Now needs no application setup in `config.exs` or `mix.exs`, thanks to getting rid of the [Soap](https://github.com/elixir-soap/soap) library due to parsing issues, and because it seems abandoned and not particularly robust to begin with.
+* XML parsing is now handled directly with [SweetXml](https://hexdocs.pm/sweet_xml/SweetXml.html).
+* Actual logging of errors in the `%Results{}` struct means you can find out what went wrong.
+* Actual handling of errors (with `{:ok, ...}` and `{:error, ...}` tuples along the pipeline across all modules means that no API call or parsing of the XML response body is made unless no errors have popped up.
