So please bare this in mind if reading through the commits and references to a v1+ release when on v0.x.
 
 As mentioned above, the DVE is "configuration driven" which means the majority of development for you as a user will be building a JSON document to describe how the data will be validated. The JSON document is known as a `dischema` file and example files can be accessed [here](./tests/testdata/). If you'd like to learn more about JSON document and how to build one from scratch, then please read the documentation [here](./docs/).
