 Each field may have optional *parameters* for how to process the data.
 The parameters are passed as a `Hash` with `Symbols` for keys.
 Parameters are designed to be lazily evaluated, possibly multiple times.
 This means that any parameter value must not have side effects.

 # Advanced Topics
+
+## Skipping over unused data
+
+Some binary structures contain data that is irrelevant to your purposes.  
+
+Say you are interested in 50 bytes of data located 10 megabytes into the
+stream.  One way of accessing this useful data is:
+
+    class MyData < BinData::Record
+      string :length => 10 * 1024 * 1024
+      string :data, :length => 50
+    end
+{:ruby}
+
+The advantage of this method is that the irrelevant data is preserved
+when writing the record.  The disadvantage is that even if you don't care
+about preserving this irrelevant data, it still occupies memory.
+
+If you don't need to preserve this data, an alternative is to use
+`skip` instead of `string`.  When reading it will seek over the irrelevant
+data and won't consume space in memory.  When writing it will write
+`:length` number of zero bytes.
+
+    class MyData < BinData::Record
+      skip :length => 10 * 1024 * 1024
+      string :data, :length => 50
+    end

 ## Wrappers
 
 Sometimes you wish to create a new type that is simply an existing type
 with some predefined parameters.  Examples could be an array with a
