+### Basic usage
+
+A basic Calendar with date selection functionality. The Calendar component is used within the DatePicker and can also be used independently.
+
+```jsx
+function Example() {
+  const [selectedDate, setSelectedDate] = useState(new Date());
+
+  return (
+    <Calendar
+      selectedDate={selectedDate}
+      onPressDate={setSelectedDate}
+    />
+  );
+}
+```
+
+### No selection
+
+A Calendar without an initially selected date.
+
+```jsx
+function Example() {
+  const [selectedDate, setSelectedDate] = useState(null);
+
+  return (
+    <Calendar
+      selectedDate={selectedDate}
+      onPressDate={setSelectedDate}
+    />
+  );
+}
+```
+
+### Seeding the calendar
+
+The `seedDate` prop controls which month the Calendar opens to when there is no selected date value. Defaults to today when undefined.
+
+```jsx
+function Example() {
+  const [selectedDate, setSelectedDate] = useState(null);
+  
+  const today = new Date(new Date().setHours(0, 0, 0, 0));
+  const seedDate = new Date(today.getFullYear(), today.getMonth() + 1, 15);
+
+  return (
+    <Calendar
+      selectedDate={selectedDate}
+      onPressDate={setSelectedDate}
+      seedDate={seedDate}
+    />
+  );
+}
+```
+
+### Minimum and maximum dates
+
+Use `minDate` and `maxDate` to restrict the selectable date range. Navigation to dates before the `minDate` and after the `maxDate` is disabled. Make sure to provide the `disabledDateError` prop.
+
+```jsx
+function Example() {
+  const [selectedDate, setSelectedDate] = useState(new Date());
+
+  const today = new Date(new Date().setHours(0, 0, 0, 0));
+  const lastMonth15th = new Date(today.getFullYear(), today.getMonth() - 1, 15);
+  const nextMonth15th = new Date(today.getFullYear(), today.getMonth() + 1, 15);
+
+  return (
+    <Calendar
+      selectedDate={selectedDate}
+      onPressDate={setSelectedDate}
+      minDate={lastMonth15th}
+      maxDate={nextMonth15th}
+      disabledDateError="Date is outside allowed range"
+    />
+  );
+}
+```
+
+### Future dates only
+
+Restrict selection to future dates by setting `minDate` to today.
+
+```jsx
+function Example() {
+  const [selectedDate, setSelectedDate] = useState(null);
+  
+  const today = new Date(new Date().setHours(0, 0, 0, 0));
+
+  return (
+    <Calendar
+      selectedDate={selectedDate}
+      onPressDate={setSelectedDate}
+      minDate={today}
+      disabledDateError="Past dates are not available"
+    />
+  );
+}
+```
+
+### Highlighted dates
+
+Use `highlightedDates` to visually emphasize specific dates or date ranges. A number is created for every individual date within a tuple range, so do not abuse this with massive ranges.
+
+```jsx
+function Example() {
+  const [selectedDate, setSelectedDate] = useState(new Date());
+  
+  const today = new Date(new Date().setHours(0, 0, 0, 0));
+  const yesterday = new Date(today.getFullYear(), today.getMonth(), today.getDate() - 1);
+  const nextWeek = new Date(today.getFullYear(), today.getMonth(), today.getDate() + 7);
+
+  return (
+    <Calendar
+      selectedDate={selectedDate}
+      onPressDate={setSelectedDate}
+      highlightedDates={[yesterday, today, nextWeek]}
+    />
+  );
+}
+```
+
+### Disabled dates
+
+Use `disabledDates` to prevent selection of specific dates or date ranges. Make sure to provide the `disabledDateError` prop.
+
+```jsx
+function Example() {
+  const [selectedDate, setSelectedDate] = useState(null);
+  
+  const today = new Date(new Date().setHours(0, 0, 0, 0));
+  
+  // Disable weekends for demonstration
+  const getNextWeekendDates = (centerDate) => {
+    const weekends = [];
+    const currentDate = new Date(centerDate);
+    
+    // Find next 4 weekends
+    for (let i = 0; i < 4; i++) {
+      // Find next Saturday
+      const daysUntilSaturday = (6 - currentDate.getDay() + 7) % 7 || 7;
+      currentDate.setDate(currentDate.getDate() + daysUntilSaturday);
+      
+      const saturday = new Date(currentDate);
+      const sunday = new Date(currentDate);
+      sunday.setDate(sunday.getDate() + 1);
+      
+      weekends.push([saturday, sunday]);
+      
+      // Move to next week
+      currentDate.setDate(currentDate.getDate() + 7);
+    }
+    
+    return weekends;
+  };
+
+  return (
+    <Calendar
+      selectedDate={selectedDate}
+      onPressDate={setSelectedDate}
+      disabledDates={getNextWeekendDates(today)}
+      disabledDateError="Weekends are not available"
+    />
+  );
+}
+```
+
+### Date ranges
+
+Highlight a date range using a tuple `[startDate, endDate]`.
+
+```jsx
+function Example() {
+  const [selectedDate, setSelectedDate] = useState(new Date());
+  
+  const today = new Date(new Date().setHours(0, 0, 0, 0));
+  const yesterday = new Date(today.getFullYear(), today.getMonth(), today.getDate() - 1);
+  const nextWeek = new Date(today.getFullYear(), today.getMonth(), today.getDate() + 7);
+
+  return (
+    <Calendar
+      selectedDate={selectedDate}
+      onPressDate={setSelectedDate}
+      highlightedDates={[[yesterday, nextWeek]]}
+    />
+  );
+}
+```
+
+### Hidden controls
+
+Hide the navigation arrows with `hideControls`. This is typically used when `minDate` and `maxDate` are set to the first and last days of the same month.
+
+```jsx
+function Example() {
+  const [selectedDate, setSelectedDate] = useState(new Date());
+  
+  const today = new Date(new Date().setHours(0, 0, 0, 0));
+  const firstDayOfMonth = new Date(today.getFullYear(), today.getMonth(), 1);
+  const lastDayOfMonth = new Date(today.getFullYear(), today.getMonth() + 1, 0);
+
+  return (
+    <Calendar
+      selectedDate={selectedDate}
+      onPressDate={setSelectedDate}
+      minDate={firstDayOfMonth}
+      maxDate={lastDayOfMonth}
+      hideControls
+    />
+  );
+}
+```
+
+### Disabled
+
+Disable the entire Calendar with the `disabled` prop.
+
+```jsx
+function Example() {
+  const selectedDate = new Date();
+
+  return (
+    <Calendar
+      selectedDate={selectedDate}
+      disabled
+    />
+  );
+}
+```
+
+### Accessibility
+
+Always provide accessibility labels for the navigation controls and error messages for disabled dates.
+
+```jsx
+function Example() {
+  const [selectedDate, setSelectedDate] = useState(new Date());
+  
+  const today = new Date(new Date().setHours(0, 0, 0, 0));
+  const nextMonth = new Date(today.getFullYear(), today.getMonth() + 1, today.getDate());
+
+  return (
+    <Calendar
+      selectedDate={selectedDate}
+      onPressDate={setSelectedDate}
+      maxDate={nextMonth}
+      disabledDateError="Date is not available for selection"
+      nextArrowAccessibilityLabel="Go to next month"
+      previousArrowAccessibilityLabel="Go to previous month"
+    />
+  );
+}
+```
