 The expression inside the if will be evaluated in bash and, if specified, the stage gets executed only if the condition returns successfully (exit 0).
 
+## Filtering stages with only_os and only_os_version statement
+
+`yip` can skip stages based on the OS and OS version:
+
+Use the `only_os` and `only_os_version` fields to specify the OS and OS version where the stage should be executed. They can be used together or separately and mixed with the normal `if` statement to provide several filtering criteria.
+
+Notice that both fields are compiled as a regex, so you can use regex patterns to match the OS and OS version.

+  foo:
+  - name: "echo ubuntu"

+Unpacks a list of OCI images to disk.
+Accepts a list of `source` and `target` paths.
+The `source` is the image to unpack, and the `target` is the path where the image will be unpacked.
+Optially a `platform` can be specified to unpack the image for a specific platform. By default it will unpack the image for the current platform.
