+# Pkg.go.dev is open source!

+
+##
+
+We’re excited to announce that the codebase for
+[pkg.go.dev](https://pkg.go.dev) is now open source.
+
+The repository lives at
+[go.googlesource.com/pkgsite](https://go.googlesource.com/pkgsite)
+and is mirrored to
+[github.com/golang/pkgsite](https://github.com/golang/pkgsite).
+We will continue using the Go issue tracker to track
+[feedback](https://github.com/golang/go/labels/go.dev)
+related to pkg.go.dev.
+
+## Contributing
+
+If you are interested in contributing to any
+[issues related to pkg.go.dev](https://github.com/golang/go/labels/go.dev),
+check out our
+[contribution guidelines](https://go.googlesource.com/pkgsite/+/refs/heads/master/CONTRIBUTING.md).
+We also encourage you to continue
+[filing issues](https://golang.org/s/discovery-feedback)
+if you run into problems or have feedback.
+
+## What’s Next
+
+We really appreciate all the feedback we’ve received so far. It has been a big
+help in shaping our
+[roadmap](https://go.googlesource.com/pkgsite#roadmap) for the coming year.
+Now that pkg.go.dev is open source, here’s what we’ll be working on next:
+
+- We have some design changes planned for pkg.go.dev,
+  to address
+  [UX feedback](https://github.com/golang/go/issues?q=is%3Aissue+is%3Aopen+label%3Ago.dev+label%3AUX)
+  that we have received. You can expect a more cohesive search and navigation
+  experience. We plan to share these designs for feedback once they are ready.
+
+- We know that there are features available on godoc.org that users
+  want to see on pkg.go.dev. We’ve been keeping track of them on
+  [Go issue #39144](https://golang.org/issue/39144),
+  and will prioritize adding them in the next few months. We also plan to
+  continue improving our license detection algorithm based on feedback.
+
+- We’ll be improving our search experience based on feedback in
+  [Go issue #37810](https://golang.org/issue/37810),
+  to make it easier for users to find the dependencies they are looking for and
+  make better decisions around which ones to import.
+
+Thanks for being patient with us in the process of open sourcing pkg.go.dev.
+We’re looking forward to receiving your contributions and working with you on
+the future of the project.
