 Welcome! This is documentation for dep, the "official experiment" dependency management tool for the Go language. Dep is a tool intended primarily for use by developers, to support the work of actually writing and shipping code. It is _not_ intended for end users who are installing Go software - that's what `go get` does.
 
-This site has both guides and reference documents. The guides are practical explanations of how to actually do things with dep, whereas the reference material provides deeper dives on specific topics. Of particular note is the [glossary](#glossary.md) - if you're unfamiliar with terminology used in this documentation, make sure to check there!

 After [installing dep](installation.md), if you're using it for the first time, check out [Creating a New Project](new-project.md). Or, if you have an existing Go project that you want to convert to dep, [Migrating to Dep](migrating.md) is probably the place to start.

 * New user guides - reference documentation is not what folks need when starting with a new tool. Step-by-step instructions are. Now [we have that](https://golang.github.io/dep/docs/introduction.html), and it caters to users who are not only new to dep, but also to Go in general.
 * Thematic organization of content - up until now, we were somewhat haphazardly flinging information into the FAQ. The body of documentation here is organized from the ground up, which will hopefully make it both more useful and easier to maintain.
-* Versioning - all of the docs are snapshotted on each release, and users can [select the version of the docs](https://golang.github.io/dep/versions.html) they want to view. Ideally, everyone should always be able to use the latest version, but this at least means you're not penalized if that's not feasible for you/your organization.
+* Versioning - docusaurus is capable of snapshotting doc versions on each release, and users will be able to select the version of the docs they want to view (though we've not enabled this just quite yet). Ideally, everyone should always be able to use the latest version, but this at least means you're not penalized if that's not feasible for you/your organization.
 * A blog - you're reading it! This is great, as it provides us a canonical place to circulate information about what's happening with the project.
 
 At the same time, the docs aren't quite comprehensive _yet_. There's more reference material and guides to be written. For example, we're still missing a guide for project maintainers on how to make releases that align well with dep's happy path.
