+# `openupm ls`
+
+The `ls` command prints the name and version of each installed package for a project.
+
+This command has the `list` alias. On this doc page we will always use the primary command name `ls`.
+
+## Options
+
+### Project directory
+
+By default openupm expects that you run the add command inside your Unity projects root directory. Based on this it determines relative paths to your package manifest etc.
+
+If you need to run openupm from somewhere else you can change the working directory using the `--chdir`/`-c` option. This option accepts an **absolute** path to a Unity projects root directory.
+
+```sh
+openupm add com.my.package -c /home/user/dev/MyProject
+```
