+Kernel Requirements
+===================
+
+
+If you want to have a full working CRUX+Docker system you will need to rebuild your kernel with the following options enabled:
+
+Networking:
+
+- CONFIG_BRIDGE
+- CONFIG_NETFILTER_XT_MATCH_ADDRTYPE
+- CONFIG_NF_NAT
+- CONFIG_NF_NAT_IPV4
+- CONFIG_NF_NAT_NEEDED
+
+LVM:
+
+- CONFIG_BLK_DEV_DM
+- CONFIG_DM_THIN_PROVISIONING
+- CONFIG_EXT4_FS
+
+Namespaces:
+- CONFIG_NAMESPACES
+- CONFIG_UTS_NS
+- CONFIG_IPC_NS
+- CONFIG_UID_NS
+- CONFIG_PID_NS
+- CONFIG_NET_NS
+
+Cgroups:
+
+- CONFIG_CGROUPS
+
+Cgroups Controllers (*optional but highly recommended*):
+
+- CONFIG_CGROUP_CPUACCT
+- CONFIG_BLK_CGROUP
+- CONFIG_MEMCG
+- CONFIG_MEMCG_SWAP
+
+You may check your kernel configuration by running the provided ``test_kernel_config.sh`` script against your kernel configuration:
+
+::
+    
+    ./test_kernel_config.sh /usr/src/linux/.config
+         
+
+Other Requirements
+==================
+
+
+You **must** have the following ``cgroup`` mount point mounted:
+
+::
+    
+    none               /cgroup       cgroup    defaults               0      0
+    
+
+Storage Backends
+================
+
+Docker comes with three main Storage Backends:
+
+- AUFS (*requires AUFS kernel/patches*)
+- devmapper
+- btrfs
+
+It is recommended you use the devmapper or btrfs backend (Default: devmapper).
+
+To use the ``btrfs`` backend edit ``/etc/docker.conf`` and modify the ``DOCKER_OPTS`` with:
+
+::
+    
+    DOCKER_OPTS="-s btrfs"
+    
+
+Docker Client
+=============
+
+The provided Docker rc script changes the group ownership of the ``/var/run/socker.sock`` UNIX Socket to ``docker``.
+
+Add yourself to this group if you wish to access the Docker daemon on localhost via UNIX Socker.
