+How to update the card database
+===============================
+
+When a new set comes out, you need to update your card database to be able to
+see the new cards in the deck editor and use them in the game. To do this,
+open the Oracle tool in the Cockatrice folder. It's a stand-alone program and
+is run directly out of the folder without running Cockatrice.
+
+When the Oracle tool is running, open the menu and select 'Download sets
+information'. Use the suggested address and click OK. After at most a few
+seconds, you should be presented a list of sets to be downloaded. Do not
+uncheck the ones you already have: they should be downloaded again. Click
+'Start download' and wait. When the process is finished, the database should
+be up to date.
+
+
+Change Card Art / Custom Card Art
+=================================
+
+Is it possible to change the card art for a specif card, not by changing the
+set order in my deck editor?
+
+YES! It is actually very simple.
+
+All you have to do is get a .JPG of the card you wish to change and name the
+actual file of the image to the cards (exact) name and add ”.Full” to the end.
+You can then take this new card image and replace the old one in your
+downloaded image folder.
+
+NOTE: Image size does not matter. Try to use a high resolution .JPG of the
+card you want to use for best quality.
+
+EXAMPLE: Let's say you wish to turn your M11 Sun Titan from its original art
+to a promo version. 
+
+If you are using Windows 7, you can find the default location for the
+Cockatrice card art files under 
+C:\Program Files (x86)>Cockatrice>pics>downloadedPics
+Once there, look for the folder of the
+set for the card we are replacing. For this example, Sun Titan is in the M11
+folder. Open the folder and paste/replace your new “Promo” Sun Titan.full[.JPG] 
+into this folder, discarding the original copy. (If you have
+not yet downloaded the original image of a card by selecting it in the deck
+editor or playing it in an online game, the card image will not yet be there)
+
+Once you have the new card image in the proper folder, you can now start
+Cockatrice (Or re-start if you already had the program open)and select the
+deck editor to see your new card image. 
+
+If you are changing the art of a card that has multiple versions in other
+sets, make sure you put the new card in whatever folder (or set) is highest
+on your card database set list.
+
+NOTE: Other players on Cockatrice will NOT see your new card image. They will
+only see whatever version of the card is in their database. 
+
+
+Use Higher Resolution Cards
+===========================
+
+Can you get better/higher resolution card art than the default downloaded card
+images already used?
+
+Yes!
+
+When you click on a card for the first time in the Deck Editor, Cockatrice
+goes onto the internet and finds an image of that card from a database on
+another website.
+
+If you find a higher resolution .JPG of a card that you wish to use on your
+Cockatrice, you can replace the image with no problem. If you can find a card
+image in the 3,000 by 1,000 pixel range, and save it as the cards (exact) name
+and add .Full to the end.
+
+If you are using Windows 7, you can find the default location for the
+Cockatrice card art files under C:\Program Files
+(x86)>Cockatrice>pics>downloadedPics. Once there, look for the folder of the
+set for the card you are replacing. (If you are not running Cockatrice as an
+administrator, look in C:\Users\username\AppData\Local\VirtualStore\Program
+Files (x86)\Cockatrice\pics\downloadedPics.)
+
+Open the folder of the set with the card, and paste/replace the new higher
+resolution .JPG image with the old low quality one.
+
+This process is the same for changing cards to custom images.
+
+NOTE: Other Cockatrice players will not see your higher resolution card art,
+they will only see the image they have in their own database.
+
+
+Booster Drafts
+==============
+Cockatrice does not support booster drafts, so players need to use an
+external service for this.
+
+Most people use http://ccgdecks.com/ so it's probably not a bad idea to
+register an account there before joining a game in Cockatrice. 
+
+
+How to link a card in the Cockatrice chat.
+==========================================
+
+To link a card in the Cockatrice chat, type out the full name of the card,
+surrounded by the [card] and [/card] tags.
+
+For example:
+
+[card]Black Lotus[/card]
+
+
+How to link a URL in the Cockatrice chat.
+=========================================
+
+To link a URL in the Cockatrice chat, type out the url, surrounded by the
+[url] and [/url] tags.
+
+For example:
+
+[url]http://www.cockatrice.de[/url]
+[url]cockatrice.de[/url]
+
