 #Database Queries
 
 * This will become a table of contents (this text will be scraped).
-{:toc}
+{:toc}
+
+We'll go through each of the CRUD (Create, Read, Update, Destroy) actions
+## Create
+
+See [http://datamapper.org/doku.php?id=docs:crud](http://datamapper.org/doku.php?id=docs:crud) if you need more info than what follows
+### New
+
+First, make an instance of ModelName
+
+    model_name = ModelName.new
+### Set Attributes
+
+Then, set its attributes to a hash
+
+    model_name.attributes = {:attr1 => val1, :attr2 => val2}
+
+Or, you could set them one at a time if you prefer (but you probably don't):
+
+    model_name.attr1 = val1
+    model_name.attr2 = val2
+### Save
+Now, save it:
+
+     model_name.save
+### Validation Outcome
+This will return <tt>true</tt> if it saves properly, passing all validations. 
+It will return <tt>false</tt> if it fails to save due to failing one or more validiations. 
+
+#### Errors
+If it does fail, 
+
+    model_name.errors
+will give you an array of the error messages from each failure. 
+
+## Read
+
+See [http://datamapper.org/doku.php?id=docs:finders](http://datamapper.org/doku.php?id=docs:finders) for more info than the following 
+### Get 1
+#### By Primary Key
+##### Serial
+
+    ModelName.get(1)
+##### String
+
+    ModelName.get("foobar")
+There are other possibilities for serial keys. That's what the DM site will help you with. 
+
+### By some attribute(s)
+You have to get the first in the db that follows the criteria if you get only one. (see below for getting several)
+
+    ModelName.first(:attr1 => val1, :attr2 => val2)
+Or just one attribute
+
+    ModelName.first(:attr => val)
+But you don't just have to make the attribute equal something. 
+
+    ModelName.first(:attr.gt => val)
+will find get the first <tt>model_name</tt> such that <tt>model_name.attr > val</tt> is true. 
+
+You can find the full list of conditions here:
+
+[http://datamapper.org/doku.php?id=docs:finders#conditions](http://datamapper.org/doku.php?id=docs:finders#conditions)
+
+### Get Many
+Getting many is just the same as getting 1, but you do
+
+    ModelName.all(args)
+rather than
+
+    ModelName.first(args)
+For example, 
+
+    ModelName.all(price.gt => 5)
+will get all ModelNames with prices over 5, just as 
+
+    ModelName.first(price.gt => 5)
+will get the first with its price over 5.
