+Termpicker is a terminal-based application designed to help users select and manipulate colors efficiently. Its keybindings are meant to be intuitive to vim users as it behaves in a modal way:
+
+Normal mode:
+
+	- h,l: decrease/increase the current slider coarsely by 5%
+	- H,L: decrease/increase the current slider finely by 1
+	- j,k: select the slider below/above
+	- <Tab>,<S-Tab>: move to the next/previous tab
+	- f,b : copy the color as an ANSI foreground/background escape code
+	- x,r,s,c: copy the color as a hex, rgb, hsl, or cmyk value
+  - ?: expand/shrink the help menu
+  - i,<cmd>: enter Insert mode
+  - q,<C-c>: quit the application
+
+Insert mode:
+
+	Manually type a color. Pressing  will cancel/leave insert mode. Anything in
+	the following formats will be used as a color input when pressing enter:
+
+	- Hex:   #rrggbb
+	- RGB:   rgb( r, g, b)
+	- CMYK:  cmyk(c, m, y, k)
+	- HSL:   hsl(h, s, l)
