 ## Forks
 
 LinuxCNC has spawned derivative projects. You may be interested to learn about what is different to LinuxCNC with
- * [OpenCN](https://gitlab.com/mecatronyx/opencnc/opencn)
+ * [OpenCN](https://mecatronyx.gitlab.io/opencnc/opencn/)
    - Different trajectory planner with focus on minimal variation of force imposed on spindle
- * [MachineKit](https://www.machinekit.io/) - addresses developers
+   - [Asymmetric Multi-Processing](https://mecatronyx.gitlab.io/opencnc/opencn/architecture/architecture.html) (AMP) assigns individual CPU cores to particular functions to single-out one core with hard realtime activities that is not affected by the Linux kernel's soft interrupts
+ * [MachineKit](https://www.machinekit.io/) - expected to appeal more to developers
    - Trying to decouple the parts into isolated functional blocks: The focus is no longer the CNC controller, but the CNC is just one application. There is - for example - the [hal\_ros\_control](github.com/tormach/hal_ros_control) for connecting to the [Robot Operating System](https://www.ros.org/).
    - The Machinetalk remote communication protocol
    - (Hopefully) more clear repository structure
 
-Forks are much appreciated as a means to tailor LinuxCNC to the needs of our users. And forks foster steady improvements as all forks compete for eyeballs, ideas and implementations.
