+			<p>Provided within, we give your specialist contractor space suit. It's even more compact, being able to fit into a pocket, and faster than the
+			Syndicate space suit available to you on the uplink. We also provide your chameleon jumpsuit and mask, both of which can be changed
+			to any form you need for the moment. The cigarettes are a special blend - it'll heal your injuries slowly overtime.</p>
+			<p>The three additional items, apart from the tablet and loadout box, have been randomly selected from what we had available. We hope
+			they're useful to you for you mission.</p>
+			<p>The contractor hub, available at the top right of the uplink, will provide you unique items and abilities. These are bought using Contractor Rep,
+			with two Rep being provided each time you complete a contract.</p>
+			<h3>Using the tablet</h3>
+			<ol>
+				<li>Open the Syndicate Contract Uplink program.</li>
+				<li>Assign yourself.</li>
+				<li>Here, you can accept a contract, and redeem your TC payments from completed contracts.</li>
+				<li>The payment number shown in brackets is the bonus you'll recieve when bringing your target <b>alive</b>. You recieve the
+				other number regardless of if they were alive or dead.</li>
+				<li>Contracts are completed by bringing the target to designated dropoff, calling for extraction, and putting them
+				inside the pod.</li>
+			</ol>
+			<p>Be careful when accepting a contract. While you'll be able to see the location of the dropoff point, cancelling will make it
+			unavailable to take on again.</p>
+			<p>The tablet can also be recharged at any cell charger.</p>
+			<h3>Extracting</h3>
+			<ol>
+				<li>Make sure both yourself and your target are at the dropoff.</li>
+				<li>Call the extraction, and stand back from the drop point</li>
+				<li>If it fails, make sure your target is inside, and there's a free space for the pod to land.</li>
+				<li>Grab your target, and drag them into the pod.</li>
+			</ol>
+			<h3>Ransoms</h3>
+			<p>We need your target for our own reasons, but we ransom them back to your mission area once their use is served. They will return back
+			from where you sent them off from in several minutes time. You will be paid in TC for your services.</p>
+
+			<p>Good luck agent. You can burn this document with the supplied lighter.</p>"}
