+For the `push` command to work, the [push configuration](/docs/templates/push.html)
 must be completed within the template.
 
 ## Options
 
-* `-create=true` - If the build configuration matching the name of the push
-  doesn't exist, it will be created if this is true. This defaults to true.
+* `-token` - An access token for authenticating the push to the Packer build
+  service such as Atlas. This can also be specified within the push
+  configuration in the template.
+
+## Examples
+
+Push a Packer template:
+
+```shell
+$ packer push template.json
+```
+
+Push a Packer template with a custom token:
 
-* `-token=FOO` - An access token for authenticating the push. This can also
-  be specified within the push configuration in the template. By setting this
-  in the template, you can take advantage of user variables.
+```shell
+$ packer push -token ABCD1234 template.json
+```
