-# LESS VARTHEME_SUBTHEME
-
-Below are instructions on how to create a Vartheme Sub theme using a LESS
-preprocessor.
-
-- [Prerequisites](#prerequisites)
-- [Additional Setup](#setup)
-- [Override Styles](#styles)
-- [Override Settings](#settings)
-- [Override Templates and Theme Functions](#registry)
-
-## Prerequisites
-- Read the @link getting_started Getting Started @endlink documentation topic.
-- You must understand the basic concept of using the [LESS] CSS pre-processor.
-- You must use a **[local LESS compiler](https://www.google.com/search?q=less
-  +compiler)**.
-- You must use the [Bootstrap Framework Source Files] ending in the `.less`
-  extension, not files ending in `.css`.
-
-## Additional Setup {#setup}
-Bootstrap library: Download and extract the **latest** 3.x.x version of
-[Bootstrap Framework Source Files] into your new sub-theme. After it has been
-extracted, the folder should read `./VARTHEME_SUBTHEME/bootstrap`.
-
-Bootstrap RTL library: Download and extract the **latest** 3.x.x version of
-[Bootstrap Framework Source Files for Right to left] into your new sub-theme.
-After it has been extracted, the folder should read
-`./VARTHEME_SUBTHEME/bootstrap-rtl`.
-
-{.alert.alert-warning} **WARNING:** Do not modify the files inside of
-`./VARTHEME_SUBTHEME/bootstrap` directly. Doing so may cause issues when 
-upgrading the [Bootstrap Framework] in the future.
-
-## Override variables.
-The `./VARTHEME_SUBTHEME/less/variables.less` file is generally 
-where you will the majority of your time overriding the variables provided by
-the [Bootstrap Framework].
-
-## Mixins.
-The `./VARTHEME_SUBTHEME/less/mixins.less` Vartheme custom mixins.
-
-The `./VARTHEME_SUBTHEME/less/base/bootstrap.base.less` file is nearly an exact
-copy from the [Bootstrap Framework Source Files]. The only difference is that it 
-injects the `variable-overrides.less` file directly after it has imported the
-[Bootstrap Framework]'s `variables.less` file. This allows you to easily 
-override variables without having to constantly keep up with newer or missing
-variables during an upgrade.
-
-The `./VARTHEME_SUBTHEME/less/base/vartheme.base.less` file contains various
-Varbase and Vartheme overrides to properly integrate with the 
-[Bootstrap Framework]. It may contain a few enhancements, feel free to edit
-this file as you see fit.
-
-The `./VARTHEME_SUBTHEME/less/base/VARTHEME_SUBTHEME.base.less` file contains
- various Varbase and Vartheme
-overrides to properly integrate with the [Bootstrap Framework]. It may contain
-a few enhancements, feel free to edit this file as you see fit.
-
-Following the SMACSS-style categorization of its CSS/LESS rules:
-
-## Base — CSS/LESS reset/normalize plus HTML element styling.
-* The `./VARTHEME_SUBTHEME/less/base/bootstrap.base.less` file contains
-  Bootstrap base.
-* The `./VARTHEME_SUBTHEME/less/base/vartheme.base.less` file contains
-  Vartheme base, which Bootstrap overrides
-* The `./VARTHEME_SUBTHEME/less/base/VARTHEME_SUBTHEME.base.less` file contains
-  VARTHEME_SUBTHEME base overrides over Vartheme and Bootstrap.
-
-##Layout — macro arrangement of a web page, including any grid systems.
-* The `./VARTHEME_SUBTHEME/less/layout/edge2edge.layout.less` file contains
-  Vartheme Edge to Edge layout for content.
-
-## Component — discrete, reusable UI elements.
-* The `./VARTHEME_SUBTHEME/less/component/bs-callouts.component.less` file
-  contains Bootstrap callouts component.
-* The `./VARTHEME_SUBTHEME/less/component/outside-in.component.less` file
-  contains Outside-in component.
-* The `./VARTHEME_SUBTHEME/less/component/navbar.admin.component.less` file
-  contains Vartheme navbar for administration.
-* The `./VARTHEME_SUBTHEME/less/component/navbar.component.less` file contains
-  Vartheme navbar.
-
-## State — styles that deal with client-side changes to components.
-
-## Theme — purely visual styling (“look-and-feel”) for a component.
-* The `./VARTHEME_SUBTHEME/less/theme/header.theme.less` file contains
-  VARTHEME_SUBTHEME header styling.
-* The `./VARTHEME_SUBTHEME/less/theme/footer.theme.less` file contains
