-# Go Blog
-
-[![Go Reference](https://pkg.go.dev/badge/golang.org/x/website/blog.svg)](https://pkg.go.dev/golang.org/x/website/blog)
-
-This directory holds the Go Blog server code and content.
-
-## Download/Install
-
-The easiest way to install is to run `go get -u golang.org/x/website/blog`. You can also
-manually git clone the repository to \$GOPATH/src/golang.org/x/website.
-
-## Running Locally
-
-To run the blog server locally:
-
-```
-go run . -reload
-```
-
-and then visit [http://localhost:8080/](http://localhost:8080) in your browser.
-
-## Contributing
-
-Articles are written in the [x/tools/present][present] format.
-Articles on the blog should have broad interest to the Go community, and
-are mainly written by Go contributors. We encourage you to share your
-experiences using Go on your own website, and [to share them with the Go
-community][community]. [Hugo][hugo] is a static site server written in Go that
-makes it easy to write and share your stories.
-
-[present]: https://godoc.org/golang.org/x/tools/present
-[community]: https://golang.org/help/
-[hugo]: https://gohugo.io/
-
-## Report Issues / Send Patches
-
-This repository uses Gerrit for code changes. To learn how to submit changes to
-this repository, see https://golang.org/doc/contribute.html.
-
-The main issue tracker for the blog is located at
-https://github.com/golang/go/issues. Prefix your issue with "x/website/blog:" in the
-subject line, so it is easy to find.
-
-## Deploying
-
-Each time a CL is reviewed and submitted, the blog is automatically deployed to App Engine.
-If the CL is submitted with a Website-Publish +1 vote,
-the new deployment automatically becomes https://blog.golang.org/.
-Otherwise, the new deployment can be found in the
-[App Engine versions list](https://console.cloud.google.com/appengine/versions?project=golang-org&serviceId=blog) and verified and manually promoted.
-
-If the automatic deployment is not working, or to check on the status of a pending deployment,
-see the “website-redeploy-blog” trigger in the
-[Cloud Build console](https://console.cloud.google.com/cloud-build/builds?project=golang-org).

 Notice the `for` `range` loop iterating over the elements of the `items` argument, which has implied type `[]int`.
 Also notice the use of the blank identifier `_` to discard the index in the loop, which we don't need in this case.
 
 Try it:
 
-.play -edit slices/prog120.go /START/,/END/
+{{play "slices/prog120.go" `/START/` `/END/`}}
 
 Another new technique in this example is that we initialize the slice by writing a composite literal,
 which consists of the type of the slice followed by its elements in braces:
 
-.code slices/prog120.go /slice := /
+{{code "slices/prog120.go" `/slice := /`}}
 
 The `Append` function is interesting for another reason.
 Not only can we append elements, we can append a whole second slice
 by "exploding" the slice into arguments using the `...` notation at the call site:
 
-.play -edit slices/prog130.go /START/,/END/
+{{play "slices/prog130.go" `/START/` `/END/`}}
 
 Of course, we can make `Append` more efficient by allocating no more than once,
 building on the innards of `Extend`:
 
-.code slices/prog140.go /Append/,/^}/
+{{code "slices/prog140.go" `/Append/` `/^}/`}}
 
 Here, notice how we use `copy` twice, once to move the slice data to the newly
 allocated memory, and then to copy the appending items to the end of the old data.
 
 Try it; the behavior is the same as before:
 
-.play -edit slices/prog140.go /START/,/END/
+{{play "slices/prog140.go" `/START/` `/END/`}}

 It's worth taking a moment to think about the final one-liner of that example in detail to understand
 how the design of slices makes it possible for this simple call to work correctly.
