+GHCiTUI is an in-terminal viewer for GHCi. The TUI is broken up into three
+primary panels, with some additional auxiliary panels for special use cases:
+
+::
+
+  ┌──────────────────┬──────┐
+  │                  │ Info │
+  │                  │      │
+  │ Source Viewer    │      │
+  │                  │      │
+  │                  │      │
+  ├──────────────────┤      │
+  │                  │      │
+  │ Live Interpreter │      │
+  │                  │      │
+  └──────────────────┴──────┘
+
+**Source Viewer:** This panel shows source code. You can step, continue,
+and toggle breakpoints among other operations in this panel.
+
+**Live Interpreter:** This panel shows the GHCi/REPL passthrough. You can
+enter expressions and GHCi commands here like you would normally.
+
+**Info:** This panel displays miscellaneous info about whatever is
+currently running. For example, it can display the current bindings and loaded
+modules.
