 # ABI Gen
 
-This package allows you to generate contract wrappers in any language from ABI files.
+This package allows you to generate TypeScript contract wrappers from ABI files.
 It's heavily inspired by [Geth abigen](https://github.com/ethereum/go-ethereum/wiki/Native-DApps:-Go-bindings-to-Ethereum-contracts) but takes a different approach.
 You can write your custom handlebars templates which will allow you to seamlessly integrate the generated code into your existing codebase with existing conventions.

 We use [handlebars](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 and a contract name because it was enough for our use-case, but if you need something else - create a PR.

 ## 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.
