+### `update_devicegroup`
+
+Updates a device group.
+
+Route: `/api/v0/devicegroups/:name`
+
+- name Is the name of the device group which can be obtained using
+  [`get_devicegroups`](#function-get_devicegroups). Please ensure that
+  the name is urlencoded if it needs to be (i.e Linux Servers would
+  need to be urlencoded.
+
+Input (JSON):
+
+- `name`: *optional* - The name of the device group
+- `type`: *optional* - should be `static` or `dynamic`. Setting this to static
+  requires that the devices input be provided
+- `desc`: *optional* - Description of the device group
+- `rules`: *required if type == dynamic* - A set of rules to determine which
+  devices should be included in this device group
+- `devices`: *required if type == static* - A list of devices that should be
+  included in this group. This is a static list of devices
+
+Examples:
+
+```curl
+curl -X PATCH -d '{"name": "NewLinuxServers"}' -H 'X-Auth-Token: YOURAPITOKENHERE' https://librenms.org/api/v0/devices/LinuxServers
+```
