+
+- Add the prerequisites to use the colorscheme.
+
+  + When Vim is used in a terminal, the 'termguicolors' feature must available
+    and it must be set on. In other words, the color scheme must be used as
+    followed.
+
+  ```vim
+  set termguicolors
+  colorscheme odyssey
+  ```
+
+  + A ISO-8613-3 compatible terminal is required.
+
+  + Otherwise, a GUI version of Vim must be used.
