 To install the standalone formatter,
 `go get -u github.com/klauspost/asmfmt/cmd/asmfmt`
 
-There are also replacements for `gofmt`, `goimports` and `goreturns`, which will process `.s` files alongside your go files when formatting a package.

-You can choose which to install:
-```
-go get -u github.com/klauspost/asmfmt/cmd/gofmt/...
-go get -u github.com/klauspost/asmfmt/cmd/goimports/...
-go get -u github.com/klauspost/asmfmt/cmd/goreturns/...
-```
-
-Note that these require **Go 1.5** due to changes in import paths.
-
-To test if the modified version is used, use `goimports -help`, and the output should look like this:
-
-```
-usage: goimports [flags] [path ...]
-    [flags]
-(this version includes asmfmt)
-```
-
-Using `gofmt -w mypackage` will Gofmt your Go files and format all assembler files as well.
