-<p>This is a simple counter contract that allows users to increment its value.</p>
-<p>This contract has a state variable <code>val</code> that persists between contract calls - the counter value. When persisted, this variable is encoded <code>as uint32</code> - a 32-bit unsigned integer.

-<p>This contract can receive <em>messages</em> from users. Unlike getters that are just read-only, messages can do write operations and change the contract&#39;s persistent state. Incoming messages are processed in <code>receive()</code> methods as transactions and cost gas for the sender.</p>
-<p>After deploying the contract, send the <code>increment</code> message by pressing the <span class="mdButton grape">Send increment</span> button in order to increase the counter value by one. Afterwards, call the getter <code>value()</code> to see that the value indeed changed.</p>
