+# Default Configuration
+
+> [!IMPORTANT]
+> If you're using a stable release of Yazi instead of the latest nightly build, make sure you're checking these files from [the shipped tag][shipped], not the latest main branch.
+
+This directory contains the default configuration files for Yazi:
+
+- [`yazi-default.toml`][yazi-default]: General configuration
+- [`keymap-default.toml`][keymap-default]: Keybindings configuration
+- [`theme-dark.toml`][theme-dark]: Dark color scheme (loaded when your terminal is in dark mode)
+- [`theme-light.toml`][theme-light]: Light color scheme (loaded when your terminal is in light mode)
+
+These files are already included with Yazi when you install the release, so you don't need to manually download or copy them to your Yazi configuration directory.
+
+However, if you want to customize certain configurations:
+
+- Create a `yazi.toml` in your config directory to override the settings in [`yazi-default.toml`][yazi-default], so either:
+  - `~/.config/yazi/yazi.toml` on Unix-like systems
+  - `C:\Users\USERNAME\AppData\Roaming\yazi\config\yazi.toml` on Windows
+- Create a `keymap.toml` in your config directory to override the settings in [`keymap-default.toml`][keymap-default], so either:
+  - `~/.config/yazi/keymap.toml` on Unix-like systems
+  - `C:\Users\USERNAME\AppData\Roaming\yazi\config\keymap.toml` on Windows
+- Create a `theme.toml` in your config directory to override the settings in [`theme-light.toml`][theme-light] and [`theme-dark.toml`][theme-dark], so either:
+  - `~/.config/yazi/theme.toml` on Unix-like systems
+  - `C:\Users\USERNAME\AppData\Roaming\yazi\config\theme.toml` on Windows
+
+For the user's `theme.toml` file, you can only apply the same color scheme to both the light and dark themes.
+
+If you want more granular control over colors, specify two different flavors for light and dark modes under the `[flavor]` section of your `theme.toml`, and override them in your respective flavor instead.
