 ## Outline
 
-Each branch has the following options:
+#### Trunk
 
-- `number`: The branch number. This is a number, but must be unique.
-- `text`: The text provided by getting to this branch. The first branch is
-  shown by default when the tree is opened.
-- `leaf`: Each leaf represents an option on the branch. The value of the leaf is
-  the number of the option shown. For example, `leaf: 1` represents the first
-  listed option.
+The `trunk` is a metadata list. Currently, the only information we really care
+about is a general description for the tree. Because of this, `trunk` is the
+key, and the description is the value.
 
-Each leaf has the following options:
+#### Branch
+
+Branches are the content of a dialogue tree. Each `branch` has the following
+options:
+
+- `number`: The branch number. This is how leaves get around. It must be unique.
+- `text`: The text provided by getting to this branch. The first branch is shown
+  by default when the tree is opened.
+- `leaf`: [Optional] The list of options for the branch. Details for leaves are
+  below. If no leaves are provided, the branch is considered a "terminal
+  branch", and the program will end after reaching it.
+
+#### Leaf
+
+Leaves are the options of a branch. Each `leaf` has the following options:
 
 - `text`: The text shown as the option.
 - `branch`: The branch this option takes the user to.
