+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).

+
+<h3>What are the Advanced options</h3>
+
+<p>
+
+These options are very useful, and not very advanced, but not needed
+for searching the data.
+
+<p>
+
+<h4>Capacity</h4>
+
+<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 commodities
+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>
+
+<h4>Capital</h4>
+
+<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>
+
+<h4>Expected losses</h4>
+
+<p>
+
+How much do you expect to lose to the dastardly brigands? Enter either
+a % (as eg - 1%) or a fraction (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 so you will need to account for that
+seperately.
+
+<p>
+
+<h4>Max distance</h4>
+
+<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 across
+the ocean for a profit? Or would you prefer to go only a short way?
+
+<p>
+
+<h3>Other fairly useful information</h3>
+
+<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>
+
+Javascript 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
+commodity/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 <a
+href="upload">read about how to upload</a>: particularly 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-speech. If you're
+interested, read the <a href="devel">Development pages</a> 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)
