 # CONTRIBUTING
 
-We use [go-swagger](https://github.com/go-swagger/go-swagger) to validate our spec against the 2.0 spec of Open API.
-
-We currently depend on version 0.18.0 of the go swagger toolchain. You can download the binary for your platform from this release page:

-https://github.com/go-swagger/go-swagger/releases/tag/0.18.0
+The go-client is an [netlify/open-api][open-api] derived http client generated using [go-swagger][go-swagger].  Starting with version [`2.0.0`](https://github.com/netlify/go-client/releases/tag/v2.0.0) it is managed with [Go 1.11 modules][go-modules], and all external tools used for generation are managed with [gobin][gobin] + Go modules.  The [`swagger.yml`][swagger] is consumed as a vendored build-time asset via a [git submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules).  See [GMBE:Tools as dependencies](https://github.com/go-modules-by-example/index/tree/master/010_tools) and [GMBE:Using `gobin` to install/run tools](https://github.com/go-modules-by-example/index/tree/master/017_using_gobin) for a deeper explanation.)
