+A kernel module that exposes the Framework Laptop (13, 16)'s battery charge limit and LEDs to userspace.
+
+## Building
+
+By default, this project will try to build a module for your running kernel.
+
+```console
+$ make
+```
+
+If you need to target a different kernel, set `KDIR`:
+
+```console
+$ make KDIR=/usr/src/linux-6.5
+```
+
+## Using
+
+You can install the module systemwide with `make modules_install`, or you can `insmod ./framework_laptop.ko`.
+
+### Battery Charge Limit

+   - `/sys/class/power_supply/BAT1/charge_control_end_threshold`
+
+### LEDs
