+4. Configuration                                  *cozybox.nvim-configuration*
+
+Cozybox ships with the nix palette overrides and surface tweaks as defaults.
+A minimal setup looks like this:
+
+>lua
+    require("cozybox").setup({
+      contrast = "hard",
+      palette_overrides = {
+        bright_blue = "#5b84de",
+        neutral_blue = "#5b84de",
+        faded_blue = "#6c86c8",
+        bright_green = "#8ec97c",
+        neutral_green = "#8ec97c",
+        faded_green = "#6fae70",
+      },
+    })
+    vim.cmd("colorscheme cozybox")
+<
+
+Call `setup()` before `colorscheme` if you want to layer more overrides on top
+of the cozybox defaults.
+
+
+OVERRIDING                             *cozybox.nvim-configuration-overriding*
+
+
+PALETTE ~
+
+You can specify your own palette colors. For example:
+
+>lua
+    require("cozybox").setup({
+        palette_overrides = {
+            bright_green = "#990000",
+        }
+    })
+    vim.cmd("colorscheme cozybox")
+<
+
+
+HIGHLIGHT GROUPS ~
+
+If you don’t enjoy the current color for a specific highlight group, now you
+can just override it in the setup. For example:
+
+>lua
+    require("cozybox").setup({
+        overrides = {
+            SignColumn = {bg = "#ff9900"}
+        }
+    })
+    vim.cmd("colorscheme cozybox")
+<
+
+It also works with treesitter groups and lsp semantic highlight tokens
+
+>lua
+    require("cozybox").setup({
+        overrides = {
+            ["@lsp.type.method"] = { bg = "#ff9900" },
+            ["@comment.lua"] = { bg = "#000000" },
+        }
+    })
+    vim.cmd("colorscheme cozybox")
+<
+
+Please note that the override values must follow the attributes from the
+highlight group map, such as:
+
+- **fg** - foreground color
+- **bg** - background color
+- **bold** - true or false for bold font
+- **italic** - true or false for italic font
+
+Other values can be seen in |`synIDattr`|
