+## Cross segment template properties
+
+To use another segment's template properties in a template, you can make use of `{{ .Segments.Segment }}`
+in your template where `.Segment` is the name of the segment you want to use with the first letter uppercased.
+
+If you want to for example use the [git][git] segment's `.UpstreamGone` property in the [exit][exit] segment, you can
+do so like this:
+
+```json
+"template": " {{ if .Segments.Git.UpstreamGone }}\uf7d3{{ else if gt .Code 0 }}\uf00d{{ else }}\uf00c{{ end }} "
+```
+
+:::warning
+For this to work, the segment you refer to needs to be in your config. The above example won't work if
+your config does not contain a git segment as Oh My Posh only populates the properties when it needs to.
