 - `--search` : Free-text team/term search within the selected category. Appends to the category query. Example: `--category "Counter Strike" --search "FlyQuest"`
 - `--matches-only` : Show only match markets (suppress non-match section).
 - `--non-matches-only` : Show only non-match markets (suppress match section).
-- `--detail` : Index of match event (1-indexed) to show detailed markets. Default: 1. Set to 0 to disable.
+- `--detail N` : Show detailed markets for match event N (1-indexed).
+  - Only applies to MATCH markets (not non-match/tournament markets)
+  - Default: 1 (auto-shows details for first match)
+  - Set to 0 to disable detail view
+  - If N exceeds available matches, shows error with available range
 - `--list-categories` : List available game categories and exit
 - `--raw` : Show all events without tradeable filter (for debugging). Includes fetch stats.
+- `--no-cache` : Disable caching and fetch fresh data from the API.
+- `--max-total` : Maximum total events to fetch before early exit. Default: no limit. Useful for quick snapshots.
+- `--starts-before` : Unix timestamp filter. Only show match events starting before this time (LIVE events always shown regardless of timestamp).
+- `--timezone` : Timezone for displaying times. Format: `UTC+X` or `UTC-X` (e.g., `UTC+7`, `UTC-5`). Default: UTC+7 (WIB).
 - `--telegram` : Send results to Telegram. Requires `BOT_TOKEN` and `CHAT_ID` in environment variables.

 ## Pagination
 
-The script fetches **ALL pages** until the API runs out of results (up to 100 pages as a safety cap).
+The script fetches **ALL pages** until the API runs out of results.
+
+### Parallel Fetching
+
+Pages are fetched in **parallel batches of 5** using ThreadPoolExecutor. This significantly reduces fetch time:
+
+| Scenario | Without Parallelization | With Parallelization |
+|----------|------------------------|---------------------|
+| 10 pages (50 events) | ~20s (2s per page × 10) | ~4s (2s per batch × 2 batches) |
+| 20 pages (100 events) | ~40s | ~8s |
+
+The script first fetches page 1 to determine total pages, then fetches remaining pages in parallel batches of 5.
 
 ## Rate Limiting
 
-- Exponential backoff: 2s → 4s → 8s → 16s → 32s
+- TokenBucket rate limiter: 10 API calls per second
+- Exponential backoff on retries: 2s → 4s → 8s → 16s → 32s
 - Max 5 retries before aborting
 
+**URL Encoding**: Special characters in `--search` (e.g., `&`, `=`, `%`, `+`, `#`) are properly encoded to prevent URL injection.
+
+## Caching
+
+Results are cached in `~/.cache/polymarket-browse/` with a **5-minute TTL** to reduce redundant API calls.
+
+- Use `--no-cache` to bypass the cache and fetch fresh data
+- Cached data is automatically used when available and not expired
+- Useful when running the script repeatedly (e.g., for monitoring)
+
 ## Odds Format
 
 All odds are shown in **cents** format:
 - `30c` = 0.30 probability
 - `95c` = 0.95 probability
 - `GamerLegion 28c | 72c Team Yandex` = GamerLegion at 28c, Team Yandex at 72c
+
+## Troubleshooting
+
+### "WARNING: Partial fetch" appears
+The API returned incomplete data due to an error/timeout. Results shown may be incomplete. Try again with `--no-cache` to force a fresh fetch.
+
+### No markets appear
+- Verify your category is correct: `--list-categories`
+- Try with `--raw` to see all events (not just tradeable ones)
+- Some categories may have no active match markets at certain times
+
+### Why did my match disappear?
+Matches are filtered out when:
+- They have ended (startTime > 4 hours ago)
+- BO2 matches ended in a tie (1-1)
+- The market has converged (bestBid >= 0.99 or bestAsk <= 0.01)
+- The event has ended (endDate passed)
+
+### Telegram not working
+- Verify `BOT_TOKEN` and `CHAT_ID` environment variables are set
+- Ensure bot is started and chat ID is correct
+- Check Telegram has not blocked the bot
+
+## Examples
+
+### Basic usage
+```bash
+# Browse Counter Strike matches (default)
+polymarket-browse
+
+# Browse NBA matches
+polymarket-browse --category NBA
+
+# Show more results
+polymarket-browse --limit 10
+```
+
+### Searching for teams
+```bash
+# Find FlyQuest Counter Strike matches
+polymarket-browse --category "Counter Strike" --search "FlyQuest"
+
+# Find any team/event across category
+polymarket-browse --category "Counter Strike" --search "Spirit"
+```
+
+### Filtering results
+```bash
+# Show only match markets (no tournament futures)
+polymarket-browse --matches-only
+
+# Show only non-match markets (tournaments, props)
+polymarket-browse --non-matches-only
+
+# Different limits for each section
+polymarket-browse --matches 10 --non-matches 5
+```
+
+### Using --detail
+```bash
+# Show details for 1st match (default behavior, auto-enabled)
+polymarket-browse --detail 1
+
+# Show details for 3rd match
+polymarket-browse --detail 3
+
+# Disable detail view
+polymarket-browse --detail 0
+```
+
+### Debugging
+```bash
+# Show all events without tradeable filter
+polymarket-browse --raw
+
+# Force fresh data (bypass cache)
+polymarket-browse --no-cache
+
+# Limit total events for quick snapshot
+polymarket-browse --max-total 20
+```
+
+### Timezone
+```bash
+# Display times in different timezone (default: UTC+7/WIB)
+polymarket-browse --timezone UTC+8
+polymarket-browse --timezone UTC-5
+```
