+**Details of the `data-hex` field:**
+
+The `data-hex` field is comprised of a JSON object as described in [GObject
+Deserialize](#gobject-deserialize) which is serialized to hex.
+
+An example of a proposal JSON object is shown here:
+
+{% highlight json %}
+{
+  "end_epoch": 1560457055,
+  "name": "test",
+  "payment_address": "yd5KMREs3GLMe6mTJYr3YrH1juwNwrFCfB",
+  "payment_amount": 5,
+  "start_epoch": 1560453490,
+  "type": 1,
+  "url": "http://test.com"
+}
+{% endhighlight %}
+
+To serialize the object, first remove all spaces from the JSON object as shown below:
+
+{% highlight json %}
+{"end_epoch":1560457055,"name":"test","payment_address":"yd5KMREs3GLMe6mTJYr3YrH1juwNwrFCfB","payment_amount":5,"start_epoch":1560453490,"type":1,"url":"http://test.com"}
+{% endhighlight %}
+
+Then convert the string to its hex equivalent as shown below. This is what will
+be used for the `data-hex` field of the `gobject prepare` command:
