-### Push Out and Update
-
-    go-selfupdate myapp 1.2
-
-This will create a folder in your project called, *public* you can then rsync or transfer this to your webserver or S3.
-
-If you are cross compiling you can specify a directory:
-
-    go-selfupdate /tmp/mybinares/ 1.2
-
-The directory should contain files with the name, $GOOS-$ARCH. Example:
-
-    windows-386
-    darwin-amd64
-    linux-arm
-
-If you are using [goxc](https://github.com/laher/goxc) you can output the files with this naming format by specifying this config:
-
-    "OutPath": "{{.Dest}}{{.PS}}{{.Version}}{{.PS}}{{.Os}}-{{.Arch}}",
