+# Overview
+
+This directory contains files that make it possible for Linux
+distributions to build Chromium using system toolchain.
+
+For more info on established way such builds are configured,
+please read the following:
+
+ - https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html
+
+Why do distros want CFLAGS, LDFLAGS, etc? Please read the following
+for some examples. This is not an exhaustive list.
+
+ - https://wiki.debian.org/Hardening
+ - https://wiki.ubuntu.com/DistCompilerFlags
+ - https://fedoraproject.org/wiki/Changes/Harden_All_Packages
+ - https://fedoraproject.org/wiki/Changes/Modernise_GCC_Flags
+ - https://fedoraproject.org/wiki/Packaging:Guidelines#Compiler_flags
+ - https://blog.flameeyes.eu/2010/09/are-we-done-with-ldflags/
+ - https://blog.flameeyes.eu/2008/08/flags-and-flags/
+
+# Usage
+
+Add the following to GN args:
+
+```
+custom_toolchain="//build/toolchain/linux/unbundle:default"
+host_toolchain="//build/toolchain/linux/unbundle:default"
+```
+
+See [more docs on GN](https://gn.googlesource.com/gn/+/master/docs/quick_start.md).
+
+To cross-compile (not fully tested), add the following:
+
+```
+host_toolchain="//build/toolchain/linux/unbundle:host"
+v8_snapshot_toolchain="//build/toolchain/linux/unbundle:host"
+```
+
+Note: when cross-compiling for a 32-bit target, a matching 32-bit toolchain
+may be needed.
