+<summary>Setting $PATH</summary>
+
+You can set the `$PATH` for your service like this:
+
+```bash
+sudo serviceman add ./myservice --path "/home/myuser/bin"
+```
+
+Snapshot your actual path like this:
+
+```bash
+sudo serviceman add ./myservice --path "$PATH"
+```
+
+Remember that this takes a snapshot and sets it in the configuration, it's not
+a live reference to your path.
