 Link to the [ina260 datasheet](https://www.ti.com/lit/gpn/INA260).
 
+This project provides two drivers:
+1) `ina260.c` that is compatible with the [hwmon](https://docs.kernel.org/hwmon/hwmon-kernel-api.html)
+2) `ina260_full.c` that provides an entire support for registers and fields of the ina260 and maximize performance over compatibility

+## Sysfs structure for the `ina260.c`

+You will mostly use the [lm-sensors](https://github.com/lm-sensors/lm-sensors) utility. Although, the ina260 registers
+are accessible from `/sys/class/hwmon/hwmon[0-9]+/registers/`.

+## Sysfs structure for the `ina260_full.c`
 - Overview: `tree /sys/kernel/ina260`
 - You can access to each device registers in `/sys/kernel/ina260/<device>/registers/`
 - You can access to each device register fields in `/sys/kernel/ina260/<device>/fields/`
