+## NAME
+podman-commit - Create new image based on the changed container
+
+## SYNOPSIS
+**podman commit**
+**TARBALL**
+[**--author**|**-a**]
+[**--change**|**-c**]
+[**--message**|**-m**]
+[**--help**|**-h**]
+
+## DESCRIPTION
+**podman commit** creates an image based on a changed container. The author of the
+image can be set using the **--author** flag. Various image instructions can be
+configured with the **--change** flag and a commit message can be set using the
+**--message** flag. The container and its processes are paused while the image is
+committed. This minimizes the likelihood of data corruption when creating the new
+image. If this is not desired, the **--pause** flag can be set to false.
