+## Adding / Updating icons
+
+All datas of icons are defined in `lua/nvim-web-devicons/_gen/icons.lua`.
+
+This file returns a table with keys and values.
+The keys are strings that are used as part of the highlight name.
+The values are tables that contain the following fields:
+
+- **color** (`string`): color for the dark theme in RGB hex code
+- **icon** (`string`): icon
+- **extension** (optional, `string[]`): file extensions (e.g. `lua`, `py`)
+- **file** (optional, `string[]`): file names (e.g. `dockerfile`, `.gitignore`)
+- **filetype** (optional, `string[]`): filetypes (e.g. `text`, `checkhealth`)
+- **os** (optional, `string[]`): OS name (e.g. `apple`, `nixos`)

-## Generate Colors
-
-Add or update icons in `lua/nvim-web-devicons/icons-default.lua`
+## Testing
 
-There are two tables where icons can be added:
-1. icons_by_filename
-2. icons_by_file_extension
-
-Add the icon in table 1. if the icon is for a file that is always named that
-way, for example `.gitconfig`. Add to table 2. if the icon is for all files
-with an extension.
-
-Each icon must have the following (this is an example):
-```lua
-[".gitconfig"] = {
-    icon = "",
-    color = "#41535b",
-    cterm_color = "0",
-    name = "GitConfig",
-},
-```
-___Key/value pairs must appear in the same exact order!___
+Run `:NvimWebDeviconsHiTest` to view the icons and their highlighting.
 
-- `color` must contain a color in the html notation
-- `cterm_color` must be below `color`, and it must contain a number (any number)
-- the correct value for `cterm_color` will be generated by the script
+Start neovim with `TERM=xterm-256color nvim ...` to test cterm.
 
-Ensure your current working directory is the repo root.
-Run `make`. This will:
-- Update `cterm_color` based on `color`
-- Generate `lua/nvim-web-devicons/icons-light.lua`
+Check with `&background` `dark` and `light`
 
-Please commit both `lua/nvim-web-devicons/icons-default.lua` and `lua/nvim-web-devicons/icons-light.lua`
+## Documentation
 
-## Test
