+# OpenCode Theme System
+
+OpenCode supports a flexible JSON-based theme system that allows users to create and customize themes easily.
+
+## Theme Loading Hierarchy
+
+Themes are loaded from multiple directories in the following order (later directories override earlier ones):
+
+1. **Built-in themes** - Embedded in the binary
+2. **User config directory** - `~/.config/opencode/themes/*.json` (or `$XDG_CONFIG_HOME/opencode/themes/*.json`)
+3. **Project root directory** - `<project-root>/.opencode/themes/*.json`
+4. **Current working directory** - `./.opencode/themes/*.json`
+
+If multiple directories contain a theme with the same name, the theme from the directory with higher priority will be used.
+
+## Creating a Custom Theme
+
+To create a custom theme, create a JSON file in one of the theme directories:
+
+```bash
+# For user-wide themes
+mkdir -p ~/.config/opencode/themes
+vim ~/.config/opencode/themes/my-theme.json
+
+# For project-specific themes
+mkdir -p .opencode/themes
+vim .opencode/themes/my-theme.json
+```
+
+## Theme JSON Format
+
+Themes use a flexible JSON format with support for:
+
+- **Hex colors**: `"#ffffff"`
+- **ANSI colors**: `3` (0-255)
+- **Color references**: `"primary"` or custom definitions
+- **Dark/light variants**: `{"dark": "#000", "light": "#fff"}`
+
+### Example Theme
+
+```json
+{
+  "$schema": "../theme.schema.json",
+  "defs": {
+    "brandColor": "#ff6600",
+    "darkBg": "#1a1a1a",
+    "lightBg": "#ffffff"
+  },
+  "theme": {
+    "primary": "brandColor",
+    "secondary": {
+      "dark": "#0066ff",
+      "light": "#0044cc"
+    },
+    "accent": 208,
+    "text": {
+      "dark": "#ffffff",
+      "light": "#000000"
+    },
+    "background": {
+      "dark": "darkBg",
+      "light": "lightBg"
+    },
+    "border": {
+      "dark": 8,
+      "light": 7
+    },
+    "borderActive": "primary"
+  }
+}
+```
+
+### Color Definitions
+
+The `defs` section (optional) allows you to define reusable colors that can be referenced in the theme.
+
+### Required Theme Colors
+
+At minimum, a theme must define:
+- `primary`
+- `secondary`
+- `accent`
+- `text`
+- `textMuted`
+- `background`
+
+### All Available Theme Colors
+
+- **Base colors**: `primary`, `secondary`, `accent`
+- **Status colors**: `error`, `warning`, `success`, `info`
+- **Text colors**: `text`, `textMuted`
+- **Background colors**: `background`, `backgroundPanel`, `backgroundElement`
+- **Border colors**: `border`, `borderActive`, `borderSubtle`
+- **Diff colors**: `diffAdded`, `diffRemoved`, `diffContext`, etc.
+- **Markdown colors**: `markdownHeading`, `markdownLink`, `markdownCode`, etc.
+- **Syntax colors**: `syntaxKeyword`, `syntaxFunction`, `syntaxString`, etc.
+
+See the JSON schema file for a complete list of available colors.
+
+## Built-in Themes
+
+OpenCode comes with several built-in themes:
+- `opencode` - Default OpenCode theme
+- `tokyonight` - Tokyo Night theme
+- `everforest` - Everforest theme
+- `ayu` - Ayu dark theme
+
+## Using a Theme
+
+To use a theme, set it in your OpenCode configuration or select it from the theme dialog in the TUI.
