+Science Research and Development System (Designed and Developed by the /tg/station crew)
+
+*insert stuff here later*
+
+*****************************************
+
+Integrating Objects into the Science Research and Development System
+
+First of all, the root /obj/ define has to have two variables added to it if it doesn't have them already:
+	var/list/origin_tech = list()
+	var/reliability = 100
+
+* The origin_tech list is a list of all the technolgies (by ID) and their level at the time the object was created (format: "ID" = #).
+If an object can't be reversed engineered, you're just going to leave this variable alone.
+* The relability var is the reliability of an object before tech modifiers. Items that start spawned and items that aren't part of the
+R&D system should just leave the reliability var at 100 and ignore it. Otherwise, you'll want to adjust it down based on the
+pre-technology-modifier reliability you want for the object. You'd also want to add some sort of mechanic that deals with that
+var as well.
+*SPECIAL NOTE: For non-carriable objects that you can deconstruct into RE'able parts, make sure to include some way of passing on
+the data from the components to the finished procuct and back again.

 	<strong>Thanks to:</strong> CDK Station devs, GoonStation devs, the original SpaceStation developers and Erikat for the new title image
 
 <h4>Changelog</h4>
+<h5>20.01.2011, r894</h5>
+<ul>
+	<LI>Pipes can now be removed and re-attached by wrenching them.
+	<LI>Mining system continues to develop. Still unaccessible to players.
+	<LI>Various map changes. Some minor lag causing things were fixed.
+	<LI>Admins have a new tool: They can now give any spell to anyone. Hurray!
+	<LI>Imadolazine now works. Maybe?
+	<LI>Singularity now releases itself if fed too much and will potentially explode.
+	<LI>Magboots now successfully prevent you from getting pulled into the singularity.
+	<LI>Strike teams immune to facehuggers. Why? I dunno.
+	<LI>Many reagent containers are adjustable so you can pour the exact amount you need.
+	<LI>No more emitters working in space, Collectors and collector controllers now ID lockable.
+	<LI>Christmas Contest plaque finally added. It's near the armor/warden's office.
+	<LI>Rocks fall, everyone dies.
+	<LI>All cyborgs and robots can now be named. Just use a pen on the cyborg's frame before the brain is inserted.
+	<LI>Knock spell now unbolts doors as well as opens them.
+	<LI>New cultist runs and other changes.
+	<LI>Added surgery tools for eventual surgery system.
+	<LI>Autolathe and Circuit Printer animations redone. Yay pretty icons.
+	<LI>AI law changes/uploads are now tracked (admin viewable).
+	<LI>Revheads now get a PDA uplink instead of a headset one.
+	<LI>Added a penlight.
+	<LI>Science Research and Development tech tree uploaded. Not really accessible by anyone yet, though.
+</ul>
+
 <h5>14.01.2011, r853</h5>
 <ul>
 	<LI>Changlings Overhauled. Now function kinda like alium (using an internal chemical reserve instead of plasma) with each ability requiring a certain amount of chemicals to activate. Both venoms removed. Several "Dart" abiliites added. They allow the changling to deafen, blind, mute, paralyze, or even transform (dead) targets.
