-This command line tool is a small wrapper of [`selfupdate.DetectLatest()`](https://godoc.org/github.com/rhysd/go-github-selfupdate/selfupdate#DetectLatest).
-
-Please install using `go get`.
-
-```
-$ go get -u github.com/rhysd/go-github-selfupdate/cmd/detect-latest-release
-```
-
-To know the usage, please try the command without any argument.
-
-```
-$ detect-latest-release

-
-For example, following shows the latest version of [github-clone-all](https://github.com/rhysd/github-clone-all).

-```
-$ detect-latest-release rhysd/github-clone-all

-Like `go get`, but it downloads and installs the latest release binary from GitHub instead.
-
-Please download a binary from [release page](https://github.com/rhysd/go-github-selfupdate/releases/tag/go-get-release)
-and put it in `$PATH` or build from source with `go get`.
-
-```
-$ go get -u github.com/rhysd/go-github-selfupdate/cmd/go-get-release
-```
-
-Usage is quite similar to `go get`. But `{package}` must be hosted on GitHub. So it needs to start with `github.com/`.
-
-```
-$ go-get-release {package}
-```
-
-Please note that this command assumes that specified package is following Git tag naming rules and
-released binaries naming rules described in [README](../../README.md).
-
-For example, following command downloads and installs the released binary of [ghr](https://github.com/tcnksm/ghr)
-to `$GOPATH/bin`.
-
-```
-$ go-get-release github.com/tcnksm/ghr
-Command was updated to the latest version 0.5.4: /Users/you/.go/bin/ghr
-
-$ ghr -version
-ghr version v0.5.4 (a12ff1c)
-```
