+# Go sigar [![Build Status](https://beats-ci.elastic.co/job/Beats/job/gosigar/job/master/badge/icon)](https://beats-ci.elastic.co/job/Beats/job/gosigar/job/master/)
+
+
+## Overview
+
+Go sigar is a golang implementation of the
+[sigar API](https://github.com/hyperic/sigar).  The Go version of
+sigar has a very similar interface, but is being written from scratch
+in pure go/cgo, rather than cgo bindings for libsigar.
+
+## Test drive

+## OS Specific Notes
+
+### FreeBSD
+
+Mount both `linprocfs` and `procfs` for compatability. Consider adding these
+mounts to your `/etc/fstab` file so they are mounted automatically at boot.
+
+```
+sudo mount -t procfs proc /proc
+sudo mkdir -p /compat/linux/proc
+sudo mount -t linprocfs /dev/null /compat/linux/proc
+```
