 # Types of [Conflation](https://github.com/ngageoint/hootenanny/blob/master/docs/user/Introduction.asciidoc)
 ## Default
-* **[Reference Conflation](https://github.com/ngageoint/hootenanny/blob/master/docs/user/OldDocs.asciidoc)** - Conflate the best geometry and tag parts of map B into map A, favoring map A's data.
+* **[Reference Conflation](https://github.com/ngageoint/hootenanny/blob/master/docs/user/OldDocs.asciidoc)** - Conflate the best geometry and tag parts of map B into map A, favoring map A's data. Use this type of conflation when you want conflated output based on the best state of both 
+input datasets.
 ## Advanced
-* **[Attribute Conflation](https://github.com/ngageoint/hootenanny/blob/master/docs/algorithms/AttributeConflation.asciidoc)** - Conflate map A with B where only tags are transferred from B to A and few or 
-no changes are made to A's geometry.
-* **[Differential Conflation](https://github.com/ngageoint/hootenanny/blob/master/docs/algorithms/DifferentialConflation.asciidoc)** - Conflate map A with B where the only data added to the output from B is in areas that don't overlap with A.  Optionally, you can configure to overwrite tags in A from B even when there is overlap or to output the unmodified map A data as well.
-* **[Horizontal Conflation](https://github.com/ngageoint/hootenanny/blob/master/docs/commands/cookie-cut.asciidoc)** (aka Cookie Cutter Conflation) - Define a specific region in map A that should not be modified and stitch in data from map B around it.
+* **[Attribute Conflation](https://github.com/ngageoint/hootenanny/blob/master/docs/algorithms/AttributeConflation.asciidoc)** - Conflate map A with B where only tags are transferred from B to A and few or no changes are made to A's geometry. Use this type of conflation when the first 
+dataset's geometry is superior to a second dataset but the attributes of the second dataset are superior to that of the first dataset.
+* **[Differential Conflation](https://github.com/ngageoint/hootenanny/blob/master/docs/algorithms/DifferentialConflation.asciidoc)** - Conflate map A with B where the only data added to the output from B is in areas that don't overlap with A. Use this type of conflation when you only
+want to fill in holes in your dataset with data from another source without modifying the first dataset. Optionally, you can configure to 
+overwrite tags in A from B even when there is overlap or to output the unmodified map A data as well.
+* **[Horizontal Conflation](https://github.com/ngageoint/hootenanny/blob/master/docs/commands/cookie-cut.asciidoc)** (aka Cookie Cutter Conflation) - Define a specific region in map A that should not be modified and stitch in data from map B around or inside of it. Use this type of
+conflation if you have a specific region of your dataset that you would like to replace with data from another dataset.
 
 There are a wide range of [configuration options](https://github.com/ngageoint/hootenanny/blob/master/conf/core/ConfigOptions.asciidoc) 
 available to customize the conflation workflows.
