+Task Template Syntax
+====================
+
+Basic template syntax
+---------------------
+A nice feature of the input task format used in Yardstick is that it supports
+the template syntax based on Jinja2.
+This turns out to be extremely useful when, say, you have a fixed structure of
+your task but you want to parameterize this task in some way.
+For example, imagine your input task file (task.yaml) runs a set of Ping
+scenarios:
+
+::
+
+  # Sample benchmark task config file
+  # measure network latency using ping
+  schema: "yardstick:task:0.1"
+
+  scenarios:
+  -
+    type: Ping
+    options:
+      packetsize: 200
+    host: athena.demo
+    target: ares.demo
+
+    runner:
+      type: Duration
+      duration: 60
+      interval: 1
+
+    sla:
+      max_rtt: 10
+      action: monitor
+
+  context:
+      ...
+
+Let's say you want to run the same set of scenarios with the same runner/
+context/sla, but you want to try another packetsize to compare the performance.
+The most elegant solution is then to turn the packetsize name into a template
+variable:
+
+::
+
+  # Sample benchmark task config file
+  # measure network latency using ping
+
+  schema: "yardstick:task:0.1"
+  scenarios:
+  -
+    type: Ping
+    options:
+      packetsize: {{packetsize}}
+    host: athena.demo
+    target: ares.demo
+
+    runner:
+      type: Duration
+      duration: 60
+      interval: 1
+
+    sla:
+      max_rtt: 10
+      action: monitor
+
+  context:
+      ...
+
+and then pass the argument value for {{packetsize}} when starting a task with
+this configuration file.
+Yardstick provides you with different ways to do that:
+
+1.Pass the argument values directly in the command-line interface (with either
+a JSON or YAML dictionary):
+
+::
+
+ yardstick task start samples/ping-template.yaml
+ --task-args'{"packetsize":"200"}'
+
+2.Refer to a file that specifies the argument values (JSON/YAML):
+
+::
+
+ yardstick task start samples/ping-template.yaml --task-args-file args.yaml
+
+Using the default values
+------------------------
+Note that the Jinja2 template syntax allows you to set the default values for
+your parameters.
+With default values set, your task file will work even if you don't
+parameterize it explicitly while starting a task.
+The default values should be set using the {% set ... %} clause (task.yaml).
+For example:
+
+::
+
+  # Sample benchmark task config file
+  # measure network latency using ping
+  schema: "yardstick:task:0.1"
+  {% set packetsize = packetsize or "100" %}
+  scenarios:
+  -
+    type: Ping
+    options:
+    packetsize: {{packetsize}}
+    host: athena.demo
+    target: ares.demo
+
+    runner:
+      type: Duration
+      duration: 60
+      interval: 1
+    ...
+
+If you don't pass the value for {{packetsize}} while starting a task, the
+default one will be used.
+
+Advanced templates
+------------------
+
+Yardstick makes it possible to use all the power of Jinja2 template syntax,
+including the mechanism of built-in functions.
+As an example, let us make up a task file that will do a block storage
+performance test.
+The input task file (fio-template.yaml) below uses the Jinja2 for-endfor
+construct to accomplish that:
+
+::
+
+  #Test block sizes of 4KB, 8KB, 64KB, 1MB
+  #Test 5 workloads: read, write, randwrite, randread, rw
+  schema: "yardstick:task:0.1"
+
+   scenarios:
+  {% for bs in ['4k', '8k', '64k', '1024k' ] %}
+    {% for rw in ['read', 'write', 'randwrite', 'randread', 'rw' ] %}
+  -
+    type: Fio
+    options:
+      filename: /home/ubuntu/data.raw
+      bs: {{bs}}
+      rw: {{rw}}
+      ramp_time: 10
+    host: fio.demo
+    runner:
+      type: Duration
+      duration: 60
+      interval: 60
+
+    {% endfor %}
+  {% endfor %}
+  context
+      ...
