+
+The yara module provides the ability to scan systems the agent is running on
+for objects which match provided yara rules. An investigator can send a list of
+yara rules to the MIG agents along with an indication of what objects should be
+scanned, and the agents will return any objects which matched and the rules that
+matched against them.
+
+Scanning is currently limited to files only at the moment.
+
+Building MIG with Yara support
+------------------------------
+Yara support is not enabled by default and requires certain dependencies on the
+build system to enable. Specifically, you will want the to make sure that the
+`yara libraries <https://github.com/VirusTotal/yara>`_ are installed on the system
+you are building MIG on.
+
+To ensure that any systems with a yara enabled agent do not need to have the yara
+library installed, MIG can be built with the yara library statically linked into
+the MIG binary.
+
+Fetch and install yara with the required options
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Download the yara tarball and compile it with the required options. You will need
+a working c compiler in addition to automake and autoconf.
+
+.. code::
+
+    $ curl -OL https://github.com/VirusTotal/yara/archive/v3.5.0.tar.gz
+    $ tar -zxvf v3.5.0.tar.gz
+    $ cd yara-3.5.0
+    $ ./bootstrap.sh
+    $ ./configure --disable-shared --disable-magic --disable-cuckoo --without-crypto
+    $ make
+    $ sudo make install
+
+From here the agent can be compiled with yara support. The yara module should be
+enabled in `conf/available_modules.go` (or whatever you have the Makefile variable
+AVAILMOD set to). Then the agent can be compiled with yara support.
+
+.. code::
+
+    $ make mig-agent WITHYARA=yes
+
+The previous example applies to Linux. If you are building an OSX agent, you might
+need a few extra environment variables to help locate things, such as:
+
+.. code::
+
+    $ env CPATH=/my/path/to/yara/include LIBRARY_PATH=/my/path/to/yara/lib make mig-agent WITHYARA=yes
+
+This should result in a mig-agent with the yara library builtin, which will work when
+deployed to hosts without libyara. Note that, as modules are used in other MIG components
+such as the client tools, you will likely want to set WITHYARA=yes when building the
+client tools as well.
+
+`tools/standalone_install.sh` also includes yara support, so can be reviewed for some
+hints on the build process.
+
+Usage
+-----
+Two options must be provided to the yara module.
+
+The `rules` should specify the path on your system containing the yara rules
+you want to send to the agents.
+
+The `files` option should be set to a string which is essentially the arguments
+you would provide to the file module. See the help output of the file module for
+more information.
+
+The following example shows a set of rules being used to scan everything in /bin
+and in /sbin on each agent system.
+
+.. code::
+
+    $ mig yara -t all -rules ./testrules.yara -files '-path /bin -path /sbin -name .'
