This SD image is a debian jessie console image with:

• a 4.1.22-ltsi-rt kernel with RT-PREEMPT patches applied
• tested on Terasic DE0-Nano-SoC Kit, other SoCKit platforms should work with appropriate dtb
• machinekit RIP-build under /home/machinekit/machinekit, all build artefacts are in place (no need to run make)
• machinekit packages are NOT installed and you do not have to!
• all machinekit build- and runtime required packages ARE installed.
• /home/machinekit/.bashrc already set up to run machinekit from the RIP build directory.
• one known-to-work configuration with hostmot2/onboard FPGA support is: machinekit/configs/hm2-soc-stepper/5i25-socfpga.ini

The machinekit.io website is formatted with the docker-jekyll-asciidoctor docker image.

to run this locally "at home":

• install docker - see https://docs.docker.com/engine/installation/linux/debian/
• pull the image from dockerhub: docker pull haberlerm/docker-jekyll-asciidoctor
• review and run the serve.sh script in the toplevel directory of your website
• review the values in config_preview.yml which were generated by the first run
• run serve.sh again, let it run to completion for the initial format of the whole site which can take 10-15mins
• stop serve.sh with ^C and run it again, it will start with --incremental --skip-initial-build for quick startup since the _site directory already exists

    origin = np.multiply(origin, 1000)
