We could've just used `--abiGlob 'src/artifacts/*.json` but we wanted to exclude some of the abi files.
The abi file should be either a [Truffle](http://truffleframework.com/) contract artifact (a JSON object with an abi key) or a JSON abi array.
+
## How to write custom templates?
+
The best way to get started is to copy [0x.js templates](https://github.com/0xProject/0x.js/tree/development/packages/0x.js/contract_templates) and start adjusting them for your needs.
We use [handlebars](http://handlebarsjs.com/) template engine under the hood.
You need to have a master template called `contract.mustache`. it will be used to generate each contract wrapper. Although - you don't need and probably shouldn't write all your logic in a single template file. You can write [partial templates](http://handlebarsjs.com/partials.html) and as long as they are within a partials folder - they will be registered and available.
+
## Which data/context do I get in my templates?
+
For now you don't get much on top of methods abi, some useful helpers and a contract name because it was enough for our use-case, but if you need something else - create a PR.
See the [type definition](https://github.com/0xProject/0x.js/tree/development/packages/abi-gen/src/types.ts) of what we pass to the render method.
+
## Output files
+
Output files will be generated within an output folder with names converted to camel case and taken from abi file names. If you already have some files in that folder they will be overwritten.
