+==== SendInstalledPackages
+
+This command is used to notify the OTA client of what packages are installed on the system. It _must_ be sent (to the command socket) after each `SendUpdateReport`, and also _may_ be sent at any other time. ATS recommends sending it on system startup, at a minimum.
+
+The command syntax is simply this:
+
+----
+SendInstalledPackages package1_name package1_version package2_name package2_version [...] packageN_name packageN_version
+----
+
+Package names and versions can't contain spaces, but there are no other character restrictions. For example, all of the package/versions listed here are valid:
+
+----
+SendInstalledPackages gcc 7.63 Movie&MusicPlayer rc2-beta3 ECU9274927BF82-firmware gitID-2fab572
+----
+
+Note, however, that all packages must have a version.
