-This repository is officially supported on the last two releases of Go, which is currently Go 1.11 and Go 1.12.
+This repository is officially supported on the last two releases of Go, which is currently Go 1.11 and Go 1.12. When using Go 1.11, a minimum minor version of Go 1.11.4 is required.
 
-It depends on a [number of external dependencies](./Gopkg.lock), and uses [dep](https://golang.github.io/dep/) to manage them (see installation instructions [here](https://golang.github.io/dep/docs/installation.html)).
+It depends on a [number of external dependencies](./go.mod), and uses Go [Modules](https://github.com/golang/go/wiki/Modules) to manage them. Running any `go` command will automatically download dependencies required for that operation.
 
-To satisfy dependencies and populate the `vendor` directory run: 
-
-```bash
-$ dep ensure -v
-```
-
-Note that if this hangs indefinitely on your machine, you might need to check if mercurial is installed.
-
-You can use dep yourself in your project and add stellar go as a vendor'd dependency, or you can just drop this repos as `$GOPATH/src/github.com/stellar/go` to import it the canonical way (you still need to run `dep ensure -v`).
-
-When creating this project, we had to decide whether or not we committed our external dependencies to the repo.  We decided that we would not, by default, do so.  This lets us avoid the diff churn associated with updating dependencies while allowing an acceptable path to get reproducible builds.  To do so, simply install dep and run `dep ensure -v` in your checkout of the code.  We realize this is a judgement call; Please feel free to open an issue if you would like to make a case that we change this policy.
+You can choose to checkout this repository into a [GOPATH](https://github.com/golang/go/wiki/GOPATH) or into any directory, but if you are using a GOPATH with Go 1.12 or earlier you must set environment variable `GO111MODULE=on` to enable Modules.
