 # Structure of this repository
 
 There are several directories with their own purpose:
 
-    build/    Used for temporary files used for the build and for build artifacts
-    scripts/  Contains scripts that are used for the build process
-    data/     Contains data required for buildng the ISO (such as boot splash)
-    tools/    Contains scripts that are used for maintainer's tasks automation
-              and other purposes, but not in ISO build process

 # Building VyOS installation images
 
 ## Prerequisites
 
-To build a VyOS image, you need Debian 8 "Jessie" environment (with jessie-backports repository).
-You can create it with [debootstrap](https://wiki.debian.org/Debootstrap) on Debian, Ubuntu and many other distributions.
-To create a Debian 8 "Jessie" environment under vyos-chroot directory, run these commands:

-Several packages are required for building the ISO: python3, live-build, pbuilder, python3-pystache. The ./configure script
-will warn you if any dependencies are missing.
-Individual packages may have other build dependencies. If some dependencies are missing, package build scripts will tell you.

-Using Dockerfile you can create your own docker container that can be used to build a VyOS ISO image.
-The Dockerfile contains some of the most used packages needed for a VyOS build ISO process.

 # Development process
 
-## git branches
-
-The default branch that contains the most recent VyOS code is called 'current' rather than 'master'.
-We know if'ts confusing, but it's not easy to fix.
-In a nutshell, the code we inherited from Vyatta Core had its master branch so out of sync with everything
-it was beyong any repair. Vyatta developers used to create a new branch not when a release is ready for
-code freeze, but rather before starting to work on a new release.
-This is hard to change in existing code, so this is just the way it is, for now.
-
-All new code goes to the 'current' branch. When it's time for a code freeze, a new branch is created
-for the release, and new code from 'current' is backported to the release branch as needed.
-
-In packages that originate from VyOS the master branch is kept in sync with "current", but we still use
-"current" as default branch for uniformity. When the last legacy package is gone, we will switch to using
-the master branch and retire "current".
-
-For branch naming we use chemical elements (hydrogen, helium, ...).
