+.TH NAME
+.PP
+nexus \- Nexus Repository Manager container image
+.SH DESCRIPTION
+.PP
+The nexus image provides a containerized packaging of the Nexus Repository Manager.
+Nexus Repository Manager is a repository manager with universal support for popular component formats including Maven, Docker, NuGet, npm, PyPi, Bower and more.
+.PP
+The nexus image is designed to be run by the atomic command with one of these options:
+.PP
+\fB\fCrun\fR
+.PP
+Starts the installed container with selected privileges to the host.
+.PP
+\fB\fCstop\fR
+.PP
+Stops the installed container
+.PP
+The container itself consists of:
+    \- Linux base image
+    \- Oracle Java JDK
+    \- Nexus Repository Manager
+    \- Atomic help file
+.PP
+Files added to the container during docker build include: /help.1.
+.SH USAGE
+.PP
+To use the nexus container, you can run the atomic command with run, stop, or uninstall options:
+.PP
+To run the nexus container:
+.IP
+atomic run nexus
+.PP
+To stop the nexus container (after it is installed), run:
+.IP
+atomic stop nexus
+.SH LABELS
+.PP
+The nexus container includes the following LABEL settings:
+.PP
+That atomic command runs the docker command set in this label:
+.PP
+\fB\fCRUN=\fR
+.IP
+LABEL RUN='docker run \-d \-p 8081:8081 \-\-name ${NAME} ${IMAGE}'
+.IP
+The contents of the RUN label tells an \fB\fCatomic run nexus\fR command to open port 8081 & set the name of the container.
+.PP
+\fB\fCSTOP=\fR
+.IP
+LABEL STOP='docker stop ${NAME}'
+.PP
+\fB\fCName=\fR
+.PP
+The registry location and name of the image. For example, Name="Nexus Repository Manager".
+.PP
+\fB\fCVersion=\fR
+.PP
+The Nexus Repository Manager version from which the container was built. For example, Version="3.0.2\-02".
+.PP
+When the atomic command runs the nexus container, it reads the command line associated with the selected option
+from a LABEL set within the Docker container itself. It then runs that command. The following sections detail
+each option and associated LABEL:
+.SH SECURITY IMPLICATIONS
+.PP
+\fB\fC\-d\fR
+.PP
+Runs continuously as a daemon process in the background
