+## Theme
+
+`lsd` can be configured with a theme file to set the colors.
+
+Theme can be configured in the [configuration file](#configuration)(color.theme),
+The valid theme configurations are:
+- `default`: the default color scheme shipped in `lsd`
+- theme-file-name(yaml): use the theme file to specify colors(without the `yaml` extension)
+
+when configured with the `theme-file-name` which is a `yaml` file,
+`lsd` will look up the theme file in the following way:
+- relative name: check the themes under XDG Base Directory, e.g. ~/.config/lsd/themes/<theme-file-name>.yaml
+- absolute name: use the file path and name to find theme file
+
+Check [Theme file content](#theme-file-content) for details.
+
+### Theme file content
+
+Theme file use the [crossterm](https://crates.io/crates/crossterm)
+configure the colors, check [crossterm](https://docs.rs/crossterm/0.20.0/crossterm/style/enum.Color.html)
+for the supported colors.
+
+Color table: https://upload.wikimedia.org/wikipedia/commons/1/15/Xterm_256color_chart.svg
+
+Please notice that color value would ignore case, both lowercase and UPPERCASE is supported.
