+# UI Components
+
+This directory contains UI components used throughout the application.
+
+## Component Types
+
+### shadcn/ui Base Components
+The following components are from [shadcn/ui](https://ui.shadcn.com) (MIT License):
+
+- **`button.tsx`** - Button component with variants
+- **`card.tsx`** - Card container with header/content/footer
+- **`input.tsx`** - Base input field
+- **`label.tsx`** - Form label
+- **`popover.tsx`** - Popover/dropdown container
+- **`select.tsx`** - Select/dropdown menu
+- **`separator.tsx`** - Horizontal/vertical divider
+- **`slider.tsx`** - Range slider input
+- **`switch.tsx`** - Toggle switch
+- **`tooltip.tsx`** - Tooltip wrapper
+
+These components are built on [Radix UI](https://www.radix-ui.com) primitives and styled with Tailwind CSS. They are copied into the codebase (not npm dependencies) and can be freely modified.
+
+**Installation command** (for adding new components):
+```bash
+npx shadcn@latest add [component-name]
+```
+
+### Custom Form Components
+Application-specific components built on top of shadcn/ui base components:
+
+- **`form-numeric-input.tsx`** - Numeric input with increment/decrement buttons
+  - Features: min/max validation, decimal places, unit display, clear button
+  - Uses: `Input`, `Button` from shadcn/ui
+
+- **`form-time-input.tsx`** - Time input with interactive picker
+  - Features: HH:MM format, hour/minute grid picker, validation
+  - Uses: `Input`, `Button`, `Popover` from shadcn/ui
+
+## Usage Examples
+
+### Basic Button
+```tsx
+import { Button } from './ui/button';
+
+<Button variant="default">Click me</Button>
+<Button variant="destructive">Delete</Button>
+<Button variant="outline">Cancel</Button>
+```
+
+### Custom Form Components
+```tsx
+import { FormNumericInput } from './ui/form-numeric-input';
+import { FormTimeInput } from './ui/form-time-input';
+
+<FormNumericInput
+  value={dose}
+  onChange={setDose}
+  increment="2.5"
+  min={0}
+  max={70}
+  unit="mg"
+  required={true}
+/>
+
+<FormTimeInput
+  value={time}
+  onChange={setTime}
+  required={true}
+  errorMessage="Time is required"
+/>
+```
+
+## Customization
+
+All components in this directory are part of your source code and can be modified:
+
+1. **Styling**: Update Tailwind classes directly in component files
+2. **Behavior**: Modify component logic as needed
+3. **Variants**: Add new variants in the `cva` configuration
+
+Changes to shadcn/ui components won't be overwritten since they're in your source tree.
+
+## Adding New Components
+
+To add more shadcn/ui components:
+
+```bash
+# List available components
+npx shadcn@latest add
+
+# Add specific component
+npx shadcn@latest add dialog
+npx shadcn@latest add dropdown-menu
+```
+
+Components will be automatically added to this directory with proper Tailwind styling.
