+# Lyric Soong variables
+
+## `kernel_version`
+
+Example:
+```
+$(call soong_config_set,lyric,kernel_version,v515)
+```
+Linux kernel version on the device. Determines the version of the LWIS userspace
+API to use in Lyric.
+
+## `soc`
+
+Example:
+```
+$(call soong_config_set,lyric,soc,gs101)
+```
+The codename for the chip used in the device. Currently only Google silicon
+is supported.
+
+## `camera_hardware`
+
+Example:
+```
+$(call soong_config_set,lyric,camera_hardware,oriole)
+```
+Specifies the set of sensors and peripherals present on the device. Determines
+the DeviceContext class that will be used.
+
+## `tuning_product`
+
+Example:
+```
+$(call soong_config_set,lyric,tuning_product,oriole)
+```
+Specifies the set of tuning data to use. This may be different than
+`camera_hardware` because not all devices have their own tuning data;
+development-only devices only have the default tuning for their SoC.
+
+## `target_device`
+
+Example:
+```
+$(call soong_config_set,google3a_config,target_device,oriole)
+```
+A mixture of `camera_hardware` and `tuning_product` used by 3A.
