 This is a seperate repo for now but will more than likely roll into the existing repo.
 
+# Building locally

 To generate, run:
 
 ```
 ansible-playbook -i inventory/all netbootxyz.yml
 ```
 
-It'll handle source generation as well as ipxe disk generation with the users settings.  The disk generation was worked on a while back so it needs work to catch it up to the existing state of netboot.xyz.
+The build output will be located in /var/www/html on Debian OSs.

+## With Docker

+docker build -t localbuild -f Dockerfile-build .

+## Local Overides

+Ansible will handle source generation as well as ipxe disk generation with your settings.  The disk generation was worked on a while back so it needs work to catch it up to the existing state of netboot.xyz.
 
 If you want to override the defaults, you can put overrides in user_overrides.yml.  See file for examples.
 
+Also note many user customizations are located in the boot.cfg file for the IPXE menus. A high level of customization can be achieved using our stock build output and hosting this along with the menus locally.
