+gopsutil: psutil for golang
+==============================
+
+.. image:: https://circleci.com/gh/shirou/gopsutil.svg?&style=shield
+        :target: https://circleci.com/gh/shirou/gopsutil
+
+.. image:: https://coveralls.io/repos/shirou/gopsutil/badge.svg?branch=master
+        :target: https://coveralls.io/r/shirou/gopsutil?branch=master
+
+.. image:: https://godoc.org/github.com/shirou/gopsutil?status.svg
+        :target: http://godoc.org/github.com/shirou/gopsutil
+
+This is a port of psutil (http://pythonhosted.org/psutil/). The challenge is porting all
+psutil functions on some architectures.
+
+
+.. highlights:: Breaking Changes!
+
+   Breaking changes is introduced at v2. See `issue 174 <https://github.com/shirou/gopsutil/issues/174>`_ .
+
+
+Migrating to v2
+-------------------------
+
+On gopsutil itself, `v2migration.sh <https://github.com/shirou/gopsutil/blob/v2/v2migration.sh>`_ is used for migration. It can not be commonly used, but it may help you with migration.
+
+
+Tag semantics
+^^^^^^^^^^^^^^^
+
+gopsutil tag policy is almost same as Semantic Versioning, but automatically increase like Ubuntu versioning.
+
+for example, `v2.16.10` means
+
+- v2: major version
+- 16: release year, 2016
+- 10: release month
+
+gopsutil aims to keep backwards-compatiblity until major version change.
+
+Taged at every end of month, but there are only a few commits, it can be skipped.
+
+
+Available Architectures
+------------------------------------
+
+- FreeBSD i386/amd64/arm
+- Linux i386/amd64/arm(raspberry pi)
+- Windows/amd64
+- Darwin i386/amd64
+- OpenBDS amd64 (Thank you @mpfz0r!)
+
+All works are implemented without cgo by porting c struct to golang struct.
+
+
+Usage
+---------
+
+Note: gopsutil v2 breaks compatibility. If you want to stay with compatibility, please use v1 branch and vendoring.
+
+.. code:: go
+
+   package main
+
+   import (
+       "fmt"
+
+       "github.com/shirou/gopsutil/mem"
+   )
+
+   func main() {
+       v, _ := mem.VirtualMemory()
+
+       // almost every return value is a struct
+       fmt.Printf("Total: %v, Free:%v, UsedPercent:%f%%\n", v.Total, v.Free, v.UsedPercent)
+
+       // convert to JSON. String() is also implemented
+       fmt.Println(v)
+   }
+
+The output is below.
+
+::
+
+  Total: 3179569152, Free:284233728, UsedPercent:84.508194%
+  {"total":3179569152,"available":492572672,"used":2895335424,"usedPercent":84.50819439828305, (snip...)}
+
+You can set an alternative location to :code:`/proc` by setting the :code:`HOST_PROC` environment variable.
+
+You can set an alternative location to :code:`/sys` by setting the :code:`HOST_SYS` environment variable.
+
+You can set an alternative location to :code:`/etc` by setting the :code:`HOST_ETC` environment variable.
+
+Documentation
+------------------------
+
+see http://godoc.org/github.com/shirou/gopsutil
+
+Requirements
+-----------------
+
+- go1.5 or above is required.
+
+
+More Info
+--------------------
+
+Several methods have been added which are not present in psutil, but will provide useful information.
+
+- host/HostInfo()  (linux)
+
+  - Hostname
+  - Uptime
+  - Procs
+  - OS                    (ex: "linux")
+  - Platform              (ex: "ubuntu", "arch")
+  - PlatformFamily        (ex: "debian")
+  - PlatformVersion       (ex: "Ubuntu 13.10")
+  - VirtualizationSystem  (ex: "LXC")
+  - VirtualizationRole    (ex: "guest"/"host")
+
+- cpu/CPUInfo()  (linux, freebsd)
+
+  - CPU          (ex: 0, 1, ...)
+  - VendorID     (ex: "GenuineIntel")
+  - Family
+  - Model
+  - Stepping
+  - PhysicalID
+  - CoreID
+  - Cores        (ex: 2)
+  - ModelName    (ex: "Intel(R) Core(TM) i7-2640M CPU @ 2.80GHz")
+  - Mhz
+  - CacheSize
+  - Flags        (ex: "fpu vme de pse tsc msr pae mce cx8 ...")
+  - Microcode
+
+- load/LoadAvg()  (linux, freebsd)
+
+  - Load1
+  - Load5
+  - Load15
+
+- docker/GetDockerIDList() (linux only)
+
+  - container id list ([]string)
+
+- docker/CgroupCPU() (linux only)
+
+  - user
+  - system
+
+- docker/CgroupMem() (linux only)
+
+  - various status
+
+- net_protocols (linux only)
+
+  - system wide stats on network protocols (i.e IP, TCP, UDP, etc.)
+  - sourced from /proc/net/snmp
+
+- iptables nf_conntrack (linux only)
+
+  - system wide stats on netfilter conntrack module
+  - sourced from /proc/sys/net/netfilter/nf_conntrack_count
+
+Some codes are ported from Ohai. many thanks.
