+## Recent Updates
+
+### Latest Features (v1.0)
+
+#### 🔄 Pull-to-Refresh
+The app now supports pull-to-refresh functionality on all timelines. Simply swipe down from the top of the timeline to fetch the latest posts from your instance.
+
+#### ⚡ Automatic Timeline Updates
+Timelines now automatically check for new posts every 30 seconds. New posts appear seamlessly at the top of your timeline without interrupting your reading experience.
+
+**How it works:**
+- Background coroutine checks for new posts using `since_id` parameter
+- Updates are silent and don't interfere with scrolling
+- Auto-refresh restarts when switching between timelines
+- Minimal network usage - only fetches posts newer than the current top post
+
+#### 🔗 Interactive Content
+Post content is now fully interactive with support for:
+- **Clickable URLs**: Tap any link to open in your default browser
+- **Hashtags**: Styled and clickable hashtags
+- **Rich HTML content**: Proper rendering of formatted text
+
+All links and hashtags are displayed in your theme's primary color with underlines for easy identification.
+
+For detailed information about all features, see [FEATURES.md](docs/FEATURES.md).

+# Features Documentation
+
+## My ActivityPub Application Features
+
+This document describes the key features of the My ActivityPub application.
+
+## Core Features
+
+### 1. Pull-to-Refresh Timeline
+
+The application now supports pull-to-refresh functionality for both public and home timelines.
+
+**How to use:**
+- Swipe down from the top of the timeline to refresh
+- A loading indicator will appear while fetching new posts
+- Timeline will be updated with the latest posts from your instance
+
+**Technical Details:**
+- Implemented using `PullToRefreshBox` from Material 3
+- Refreshes without clearing the current timeline on error
+- Works for both Public Federated Timeline and Home Timeline
+
+### 2. Automatic Timeline Updates
+
+Timelines automatically check for new posts every 30 seconds and update seamlessly.
+
+**Behavior:**
+- Checks for new posts using the `since_id` parameter
+- New posts are added to the top of the timeline
+- Updates happen silently in the background
+- No interruption to user scrolling or reading
+- Auto-refresh starts automatically when switching timelines
+
+**Technical Details:**
+- Uses Kotlin Coroutines with a 30-second delay loop
+- Implemented in `TimelineViewModel.startAutoRefresh()`
+- Cancels previous auto-refresh job when switching timelines
+- Silently fails on network errors to avoid interrupting user experience
+
+### 3. Clickable Links and Hashtags
+
+Post content now supports interactive links and hashtags.
+
+**Supported Elements:**
+- **HTTP/HTTPS URLs**: Click to open in external browser
+- **Hashtags**: Styled with primary color and underline
+- **HTML Content**: Properly parsed and displayed
+
+**User Experience:**
+- Links and hashtags are displayed in the primary theme color
+- Underlined for easy identification
+- Tap any link to open in default browser
+- Hashtags are visually distinct
+
+**Technical Details:**
+- Uses `AnnotatedString` with `ClickableText`
+- Regex patterns to identify URLs and hashtags
+- HTML content is parsed using Android's `Html.fromHtml()`
+- Link annotations for click handling
+
+## Timeline Features
