 * **Extreme memory footprint**: A minimal bootable image, including bootloader, operating system components and a complete C++ standard library is currently 693K when optimized for size.
 * **KVM and VirtualBox support** with full virtualization, using [x86 hardware virtualization](https://en.wikipedia.org/wiki/X86_virtualization) whenever available (it is on most modern x86 CPU's). In principle IncludeOS should run on any x86 hardware platform, even on a physical x86 computer, given appropriate drivers. Officially, we develop for- and test on [Linux KVM](http://www.linux-kvm.org/page/Main_Page), which power the [OpenStack IaaS cloud](https://www.openstack.org/), and [VirtualBox](https://www.virtualbox.org), which means that you can run your IncludeOS service on both Linux, Microsoft Windows and Apple OS X. 
 * **C++11/14 support**
-    * Full C++11/14 language support with [clang](http://clang.llvm.org) v3.6 and later.
-    * Standard C++ library** (STL) [libc++](http://libcxx.llvm.org) from [LLVM](http://llvm.org/)

+    * Standard C++ library (STL) [libc++](http://libcxx.llvm.org) from [LLVM](http://llvm.org/)
     * Exceptions and stack unwinding (currently using [libgcc](https://gcc.gnu.org/onlinedocs/gccint/Libgcc.html))
     * *Note:* Certain language features, such as threads and filestreams are currently missing backend support. 
 * **Standard C library** using [newlib](https://sourceware.org/newlib/) from [Red Hat](http://www.redhat.com/)
 * **Virtio Network driver** with DMA. [Virtio](https://www.oasis-open.org/committees/tc_home.php?wg_abbrev=virtio) provides a highly efficient and widely supported I/O virtualization. Like most implementations IncludeOS currently uses "legacy mode", but we're working towards the new [Virtio 1.0 OASIS standard](http://docs.oasis-open.org/virtio/virtio/v1.0/virtio-v1.0.html)
 * **A highly modular TCP/IP-stack** written from scratch, still under heavy development.
-    * TCP: Just enough to serve HTTP
-    * UDP: Enough to support a high performance DNS service
-    * DHCP: Basic support, tested on VirtualBox and KVM
-    * ICMP: Enough to answer ping, no control messages yet
+    * TCP: Not all the RFC's are impelemented yet, but it's stable and usable, including congestion control and common opitons.
+    * UDP: More or less complete, enough to support a high performance DNS service
+    * DHCP: Basic support, tested on VirtualBox, KVM and OpenStack
+    * ICMP: Enough to answer ping, no integration with the rest of the stack yet.
     * ARP

      * For the full source build, you'll need at least 1024 MB memory
-     * In order to support VGA graphics inside a VM, we recommend a lightweight GUI, such as  [lubuntu](http://lubuntu.net/blog/lubuntu-1404-trusty-tahr-released) which runs great inside a virtual machine.

 * Build a GCC cross compiler along the lines of the [osdev howto](http://wiki.osdev.org/GCC_Cross-Compiler) which we really only need to build `libgcc` and `newlib`.
 * Build [Redhat's newlib](https://sourceware.org/newlib/) using the cross compiler, and install it according to `./etc/build_newlib.sh`. The script will also install it to the mentioned location.
 * Build a 32-bit version of [LLVM's libc++](http://libcxx.llvm.org/) tailored for IncludeOS.
