# Swarm ENS interface |
||||||
|
|
||||||
|
## Usage |
||||||
|
|
||||||
|
Full documentation for the Ethereum Name Service [can be found as EIP 137](https://github.com/ethereum/EIPs/issues/137). |
||||||
|
This package offers a simple binding that streamlines the registration arbitrary utf8 domain names to swarm content hashes. |
||||||
|
|
||||||
|
## Development |
||||||
|
|
||||||
|
The SOL file in contract subdirectory implements the ENS root registry, a simple first-in-first-served registrar for the root namespace, and a simple resolver contract; they're used in tests, and can be used to deploy these contracts for your own purposes. |
||||||
|
|
||||||
|
The solidity source code can be found at [github.com/arachnid/ens/](https://github.com/arachnid/ens/). |
||||||
|
|
||||||
|
The go bindings for ENS contracts are generated using `abigen` via the go generator: |
||||||
|
|
||||||
|
```shell |
||||||
|
godep go generate ./swarm/services/ens |
||||||
|
``` |
||||||
|
|
||||||
|
see the preprocessor directives in leading comments of ens.go and ens_test.go |
