+There are 4 main types of settings:
+
+1. Icon: the text that gets rendered
+2. Highlight: the color for text & backgrounds
+3. Style: how different components are rendered
+4. Window Options: handles conceal behavior
+
+There are 2 main ways array like values are accessed:
+
+1. Cycle: Indexed `mod` the length.
+   Example: `{ 1, 2, 3 }` @ 4 = 1.
+2. Clamp: Indexed normally but larger values use the last value in the array.
+   Example: `{ 1, 2, 3 }` @ 4 = 3.
+
+## Icon
+
+### headings
+
+Replace the `#` characters in front of headings.
+
+The number of `#` characters in the heading determines the level of the heading.
+
+The level is used to index into the table using a cycle.
+
+The icon is pre-pendeded with spaces to fill the gap and hide any additional `#`.
+
+### dash
+
+Gets repeated across the window's width when a `thematic_break` is found.
+
+### bullets
+
+Replace the `-`, `+`, and `*` characters in front of list items.
+
+A different bullet is used depending on the level of nesting for the list item.
+
+The nesting level is used to index into the table using a cycle.
+
+If the character is before a checkbox, rather than changing the icon a conceal
+is used to hide the character.
+
+### checkbox
+
+The checked `[ ]` & unchecked `[x]` are directly replaced with these values.
+
+### quote
+
+Replaces the `|` character in front of `block_quotes`.
+
+### callout
+
+This is a special instance of a `block_quote`.
+
+When the `callout` syntax is used the start, i.e. `[!NOTE]`, is replaced
+with this text.
+
+## Highlight
+
+Options are all contained in the `highlights` table.
+
+For the most part the highlight group is used directly when writing the
+associated icons. We'll cover some of the specific behaviors.
+
+### heading
+
+Both `backgrounds` and `foregrounds` are indexed by the level of the heading
+using a clamp.
+
+Both values are applied to the icon, however the background extends through
+the entire line.
+
+### table
+
+The `head` is used for the table heading, delimitter, and the line above.
+
+The `row` is used for everything else, so the main table rows and the line below.
+
+## Style
+
+### code_style
+
+Determines how `fenced_code_block`s are rendered.
+
+- `none`: disables all rendering
+- `normal`: adds background highlight group to the code block
+- `full`: `normal` + language icon & name above the code block
+
+### table_style
+
+Determines how `table`s are rendered.
+
+- `none`: disables all rendering
+- `normal`: applies the `cell_style` rendering to each row of the table
+- `full`: `normal` + a top & bottom line that fill out the table when lengths match
+
+### cell_style
+
+Determines how `table cell`s are rendered.
+
+- `overlay`: writes completely over the table, removing conceal behavior and highlights
+- `raw`: replaces only the `|` icons in each row, leaving the cell completely unmodified
+
+## Window Options
+
+Options are all contained in the `win_options` table.
+
+This changes the `conceallevel` & `concealcursor` when rendering. When not rendering
+the value is changed back to the users configured value.
