+  Make sure to install one of the currently supported <Link to={ROUTE_PORTS}>terminal emulator port projects</Link> <strong>before</strong> installing Nord dircolors.
+
+[`dircolors`][gnu-docs-dircolors] uses the 16 color codes provided by the terminal emulator.
+**When used with another color theme** than the one provided by one of Nord's terminal emulator ports, the colors for dircolors won't use <Link to={ROUTE_DOCS_COLOR_AND_PALETTES}>Nord's color palettes</Link>!
+This will result in different styles than those defined by Nord dircolors and could make it appear that there is a problem with the theme while the actual problem are missing Nord colors.
+
+Read the GitHub Gist about [terminal colors][gh-gist-terminal-colors] for more information about terminal color specifications.

+
+## Installation
+
+Nord dircolors can be installed for all application that respect the `LS_COLORS` environment variable like GNU core utils [`ls`][wiki-ls], [`tree`][wiki-tree] or modern projects like [`fd`][gh-sharkdp/fd].
+
+To automatically load Nord dircolors for every shell session, download the [`dir_colors`][gh-tree-dir_colors] file and place it as `~/.dir_colors` in your [home directory][wiki-home_dir].
+
+### Latest Development State
+
+To always use the latest development state of Nord dircolors, [clone the repository][repo] and create a [symbolic link][wiki-symlink] of the `src/dir_colors` file to `~/.dir_colors` in your [home directory][wiki-home_dir] afterwards:
+
+```sh
+ln -sr "$PWD/src/dir_colors" "~/.dir_colors"
+```
+
+## Activation
+
+To activate and use Nord dircolors as your default color theme for all sessions, load the theme with `dircolors` by adding the following snippet to the configuration file of your shell (`~/.bashrc`, `~/.zshrc`, …):
+
+```sh
+test -r "~/.dir_colors" && eval $(dircolors ~/.dir_colors)
+```

+
+[dircolors][gnu-docs-dircolors] is a utility that sets the `LS_COLORS` environment variable respected by [GNU `ls`][wiki-ls] when used with the `--color` option. It converts the _color database file_ provided by this theme (`dir_colors`), converts it into the parsable format for the GNU `ls` command and stores it in the `LS_COLOR` environment variable.
+
+Other distributions/platforms/operating systems like [macOS][wiki-macos] are based on [BSD][wiki-bsd] and using a different implementation of the `ls` command that uses a different format for color definitions stored in the `LSCOLOR` environment variable (no underscore).
+
+The `dircolors` utility only supports GNU `ls` and therefore this theme is also only compatible with the GNU `ls` command. It has no effect when used with different implementations.
+
+Please read the [manual pages of the `dircolors(1)` utility][linux-man-dircolors] and it's [configuration file `dir_colors(5)`][linux-man-dir_colors] for more information about supported terminal codes/sequences and platforms.

+
+Nord dircolors provides highlighting for a lot of different data types, their attributes and file system permissions. This document contains a general overview of these types including descriptions about their applied Nord styles.

+
+## Global Defaults
+
+The following styles are applied globally to essential data and node types as well as their file system permissions.
+
+### Permissions
+
+The styles are applied for files and directories with different [file system permissions][wiki-fs_perm].
+
+Directories using `nord9` as foreground color and a `bold` font style.
+If the `t` permission flag is set the background color is `nord9` instead while `nord4` is used as foreground color using the `underline` font style. Also if the `o+w` permission flags are set too the font uses the `bold` style instead.
+
+For directories with the `777` permission value both the `bold` and `underline` font styles are used.
