-Steps in finding differences:
+# AngleSharp.Diffing 
+This library makes it possible to compare a AngleSharp _control_ `INodeList` and a _test_ `INodeList` and get a list of differences between them.
 
-```
-var diffs : []
-var currentPath : string
-var controlNodes : []
-var testNodes : []
-foreach (ctrlNode, index) in controlNodes
-    if(shouldSkip(ctrlNode)) continue;
+The _control_ nodes represents the expected, i.e. how the nodes are expected to look, and the _test_ nodes represents the other nodes 
+that should be compared to the _control_ nodes.
 
-    ctrlSource = {ctrlNode, index, currentPath}
-    testNode = nodeMatcher(ctrlSource)
+## Usage
 
-
-    testSource = 
-
-
-nodeMatcher() ->
-``` 
-
-
-
-- NodeFilter - filters away nodes that should not be part of the comparison
-  - Inline filter(ignorer)
-- NodeMatcher - matches a control-node with a test-node for comparison
-- Compare nodes by:
-  - AttributeFilter - filters away attributes not compared
-    - Inline filter(ignorer)
-  - AttributeMatcher - matches control-attr with test-attr for comparison
-    - Inline matcher(css selector)
-  - For each attribute-compare set:
-    - apply attribute compare function
-    - apply inline-attribute-compare function
-  - For each child-node - compare recursively between control and test child-nodes
+## Difference engine steps
+The heart of the library is the `HtmlDifferenceEngine`, which goes through the following steps to determine if the 
+control `INodeList` is the same as the test `INodeList`.
