+<h1>How to use YARRG.</h1>
+A basic introduction to YARRG.
+
+<h2>What is YARRG for?</h2>
+
+<p>
+
+YARRG is designed to help pirates make profitable trades, it is not
+designed as a trading tutorial and some familiarity with trading in
+YPP is assumed. <a
+href="http://yppedia.puzzlepirates.com/Trading">yppedia.puzzlepirates.com/Trading</a>
+contains some advice on trading basics.
+
+<p>
+
+<h2>So how do I use it then?</h2>
+
+<p> First look at the top of the page. You need to select your Ocean,
+the sort of Interface you would like and the type of Query you wish to
+ask.
+
+
+<p>
+
+<h2>Selecting your Ocean: </h2>
+
+<p>
+
+<b>Which ocean do you want to trade on?</b> just click on that ocean's
+name.
+
+<p>
+
+<h2>Selecting your Interface:</h2>
+
+<p> You can choose to enter commodity and island names by typing them
+into a text entry field or by selecting them from a drop down menu.
+The "select from menu" option allows only a restricted number of
+options to be entered into each field.
+
+<p>
+
+<h2>Type of Query:</h2>
+
+<p>
+
+There are currently four types of query available, which answer
+slightly different questions.
+
+<p>
+
+<h3>Trades for route: </h3>
+
+<p>
+
+<b>For pirates who know where they are going.</b> Trades for route allows
+you to enter a route that you are planning to sail and find out if
+there are any profitable trades you can make along the way. This is
+for pirates who already have a definate sailing plan for some reason.
+Under "Enter Route" you need to type (or select from menus) the names
+of the islands or Archipelagoes that you plan to visit. If you wish
+to know about arbitrage opportunities at an island you can enter just
+that island name. If you enter only one Archipelago then you will get
+arbitrage opportunities in that archipelago, if you enter the same
+archipelago twice you'll get trades within that archipelago.
+
+<p>
+
+<h3>Prices for commodity: </h3>
+
+<p>
+
+<b>For pirates wanting to sell or buy a specific comodity</b> prices for
+commodity returns the best buy and sell prices for the selected
+commodity at each island where trades are available. Type (or select
+from a menu) the name of one commodity at a time. This is useful for
+pirates wishing to purchase or sell a specific commodity and wanting
+the best price.
+
+<p>
+
+<h3>Offers at location: </h3>
+
+<p>
+
+<b>For pirates wanting more details about comodity prices at specified
+locations.</b> Offers at location returns all the offers to buy and sell
+wood at the selected location(s). Type (or select) a commodity and the
+islands (or achipelagos) you are interested in. This is useful when
+the best buy or sell offer is for only a small quantity, you can check
+what the others offers are like.
+
+<p>
+
+<h3>Find Profitable route: </h3>
+
+<p>
+
+<b>For pirates just wanting to make some poe moving comodities about.</b> Find
+Profitable Route finds you a profitable trading route, first select
+either "open-ended" (which might take you anywhere) or "circular"
+(which takes you back to where you started) then type (or select) your
+starting point (or points - you may for instance have two ships in
+different locations either of which you could use).
+
+<p>
+
+<h2>Data age: </h2>
+
+<p>
+
+Data age tells you how long ago data was uploaded from each island in
+your ocean, data changes very quickly and trusting old data to be
+accurate is unlikely to be rewarding.
+
+<p>
+
+<h2>What do the results mean:</h2>
+
+<p>
+
+Prices for commodity and offers at location give very similar results;
+there will be two tables the first titled Offers to BUY your
+commodity, the second offers to SELL it. The tables can be resorted
+by your prefered heading by clicking on the arrows.
+
+<p>
+
+Trades for route and Find profitable route both return voyage plans.
+Find profitable route has an additional step to get at your results -
+when you enter your query you are given a list of 15 good routes for
+total profit and 15 good routes for profit per league which visit
+different islands; select your prefered route, perhaps you will choose
+to take the best profit or perhaps you need to miss out one island
+because it is blockaded or another because you don't have the charts
+to get to or from it. If you have asked for a trade for route or
+after selecting the profitable route you prefer you will get a Voyage
+trading plan - this provides you with instructions for what to do (buy
+this, sell that, sail there).
+
+<p>
+
+Sometimes no useful trades are available, in this case the results
+section says simply "No profitable trading opportunities were found".
+
+<p>
+
+After this there is a table reporting the age of the data used. And
+then a table of Relevant trades which lists just about everything you
+could want to know about each trade the plan suggests you make(yes,
+this table is fairly complicated), the ticky boxes down the side of
+this table allow you to choose which trades you like the look of -
+untick any that you are not interested in (for instance you may be
+uninterested in trades with a low profit margin).
+
+<p>
+
+<h2>What are the Advanced options:</h2>
+
+<p>
+
+These options are very useful, and not very advanced, but not needed
+for searching the data.
+
+<p>
+
+<h3>Capacity: </h3>
+
+<p>
+
+You can't trade more than fits in your hold. If you don't say
+anything YARRG assumes that you have infinite hold space (perhaps you
+will go over the route many times). You can enter a ship-type, a mass
+or a volume; additionally you can subtract quantities of comodities
+from a ship-type (for instance 'sloop - 10 grog' gives the capacity of
+a sloop that has 10 grog already on board); click the ? by this field
+to get a full description of permitted entries here.
+
+<p>
+
+<h3>Capital:</h3>
+
+<p>
+
+How much poe do you have? If you don't say anything YARRG assumes you
+have infinite poe to spend, but you probably don't. Enter the amount
+you are willing to spend on commodities for trading with.
+
+<p>
+
+<h3>Expected losses:</h3>
+
+<p>
+
+How much do you expect to lose to the dasterdly brigands? enter either
+a % (as eg - 1%) or a fracition (as eg - 1/100) of the goods you
+expect to loose to Brigands. Brigands take 10% if they defeat you,
+but only you know how often you are defeated. Note that this doesn't
+include rum-consumed, and you will need to account for that
+seperately.
+
+<p>
+
+<h3>Max distance: </h3>
+
+<p>
+
+How far are you willing to sail today? The default is 20 leagues, the
+maximum supported is 35. Are you willing to sail all the way accross
+the ocean for a profit? or would you prefer to go only a short way?
+
+<p>
+
+<h2>Other fairly useful information:</h2>
+
+<p>
+
+The search information is encoded in the URL - you can bookmark pages
+for searches you want to perform a lot and go straight to them without
+re-entering you data (or you can copy the URL and tell your hearties
+and crew mates if you want to). There's no need to come back to the
+introductory page each time.
+
+<p>
+
+Java magic - when you type things into the text entry fields YARRG
+will try to guess what you meant, if you pause for a moment then
+beneath the text entry field you'll see what YARRG thinks you meant if
+it's got it correct you don't have to type any more of that
+comodity/island name, just go on to the next one.
+
+<p>
+
+You'll probably want to upload data to ensure you have fresh data
+available, unfortunately YARRG only has a Linux upload client at
+present (a windows one is in the works). You should read
+http://yarrg.chiark.net/intro and the linked README page for
+information about the client which contain easy-to-follow instructions
+to download, install and run it in the form of a few comand line
+instructions that you can copy and paste.
+
+<p>
+
+It's all free, both free-as-in-beer or free-as-in-speach. If you're
+interested, read the 'development' pages for more info about how to
+contribute or how to run your own website using YARRG data (perhaps
+you don't like our colour choices)
