+### Supported Platforms
+Official Docker images are built for:
+- **linux/amd64** (x86_64)
+- **linux/arm64** (ARM 64-bit, Raspberry Pi 3/4/5, Apple Silicon)
+
+**Note**: ARMv7 support (32-bit ARM, Raspberry Pi 2) was dropped in v1.2.0 due to incompatibility with modern security libraries on Alpine Linux. Users with ARMv7 devices can either:
+- Use an older version (v1.1.x or earlier)
+- Build locally with pinned dependencies (see notes in Dockerfile)
+- Upgrade to a 64-bit OS if hardware supports it (Raspberry Pi 3+)

+## Google Custom Search (BYOK)
+
+If Google blocks traditional search scraping (captchas, IP bans), you can use your own Google Custom Search Engine credentials as a fallback. This uses Google's official API with your own quota.
+
+### Why Use This?
+
+- **Reliability**: Official API never gets blocked or rate-limited (within quota)
+- **Speed**: Direct JSON responses are faster than HTML scraping
+- **Fallback**: Works when all scraping workarounds fail
+- **Privacy**: Your searches still don't go through third parties—they go directly to Google with your own API key
+
+### Limitations vs Standard Whoogle
+
+| Feature          | Standard Scraping        | CSE API             |
+|------------------|--------------------------|---------------------|
+| Daily limit      | None (until blocked)     | 100 free, then paid |
+| Image search     | ✅ Full support          | ✅ Supported         |
+| News/Videos tabs | ✅                       | ❌ Web results only  |
+| Speed            | Slower (HTML parsing)    | Faster (JSON)       |
+| Reliability      | Can be blocked           | Always works        |
+
+### Setup Steps
+
+#### 1. Create a Custom Search Engine
+1. Go to [Programmable Search Engine](https://programmablesearchengine.google.com/controlpanel/all)
+2. Click **"Add"** to create a new search engine
+3. Under "What to search?", select **"Search the entire web"**
+4. Give it a name (e.g., "My Whoogle CSE")
+5. Click **"Create"**
+6. Copy your **Search Engine ID** 
+
+#### 2. Get an API Key
+1. Go to [Google Cloud Console](https://console.cloud.google.com/)
+2. Create a new project or select an existing one
+3. Go to **APIs & Services** → **Library**
+4. Search for **"Custom Search API"** and click **Enable**
+5. Go to **APIs & Services** → **Credentials**
+6. Click **"Create Credentials"** → **"API Key"**
+7. Copy your API key (looks like `AIza...`)
+
+#### 3. (Recommended) Restrict Your API Key
+To prevent misuse if your key is exposed:
+1. Click on your API key in Credentials
+2. Under **"API restrictions"**, select **"Restrict key"**
+3. Choose only **"Custom Search API"**
+4. Under **"Application restrictions"**, consider adding IP restrictions if using on a server
+5. Click **Save**
+
+#### 4. Configure Whoogle
+
+**Option A: Via Settings UI**
+1. Open your Whoogle instance
+2. Click the **Config** button
+3. Scroll to "Google Custom Search (BYOK)" section
+4. Enter your API Key and CSE ID
+5. Check "Use Custom Search API"
+6. Click **Apply**
+
+**Option B: Via Environment Variables**
+```bash
+WHOOGLE_CSE_API_KEY=AIza...
+WHOOGLE_CSE_ID=23f...
+WHOOGLE_USE_CSE=1
+```
+
+### Pricing & Avoiding Charges
+
+| Tier | Queries          | Cost                  |
+|------|------------------|-----------------------|
+| Free | 100/day          | $0                    |
+| Paid | Up to 10,000/day | $5 per 1,000 queries  |
+
+**⚠️ To avoid unexpected charges:**
+
+1. **Don't add a payment method** to Google Cloud (safest option—API stops at 100/day)
+2. **Set a billing budget alert**: [Billing → Budgets & Alerts](https://console.cloud.google.com/billing/budgets)
+3. **Cap API usage**: APIs & Services → Custom Search API → Quotas → Set "Queries per day" to 100
+4. **Monitor usage**: APIs & Services → Custom Search API → Metrics
+
+### Troubleshooting
+
+| Error               | Cause                     | Solution                                                        |
+|---------------------|---------------------------|-----------------------------------------------------------------|
+| "API key not valid" | Invalid or restricted key | Check key in Cloud Console, ensure Custom Search API is enabled |
+| "Quota exceeded"    | Hit 100/day limit         | Wait until midnight PT, or enable billing                       |
+| "Invalid CSE ID"    | Wrong cx parameter        | Copy ID from Programmable Search Engine control panel           |
 
 ## Usage
 Same as most search engines, with the exception of filtering by time range.
 
 To filter by a range of time, append ":past <time>" to the end of your search, where <time> can be `hour`, `day`, `month`, or `year`. Example: `coronavirus updates :past hour`
 
+### JSON results (API)
+Whoogle can return filtered results as JSON using the same sanitization rules as the HTML view.
+
+- Send `Accept: application/json` or append `format=json` to the search URL.
+- Example: `/search?q=whoogle` with `Accept: application/json`, or `/search?q=whoogle&format=json`.
+- Response shape:
+
+```
+{
+  "query": "whoogle",
+  "search_type": "",
+  "results": [
+    {"href": "https://example.com/page", "text": "Example Page"},
+    ...
+  ]
+}
+```
+
+Special cases:
+- Feeling Lucky returns HTTP 303 with body `{ "redirect": "<url>" }`.
+- Temporary blocks (captcha) return HTTP 503 with `{ "blocked": true, "error_message": "...", "query": "..." }`.
+

+### Static asset bundling (optional)
+Whoogle can optionally serve a single bundled CSS and JS to reduce the number of HTTP requests.
+
+- Enable by setting `WHOOGLE_BUNDLE_STATIC=1` and restarting the app.
+- On startup, Whoogle concatenates local CSS/JS into hashed files under `app/static/build/` and templates will prefer those bundles.
+- When disabled (default), templates load individual CSS/JS files for easier development.
+- Note: Theme CSS (`*-theme.css`) are still loaded separately to honor user theme selection.
+
+## User Agent Generator Tool
+
+A standalone command-line tool is available for generating Opera User Agent strings on demand:
+
+```bash
+# Generate 10 User Agent strings (default)
+python misc/generate_uas.py
+
+# Generate custom number of UAs
+python misc/generate_uas.py 20
+```
+
+This tool is useful for:
+- Testing different UA strings
+- Generating UAs for other projects
+- Verifying UA generation patterns
+- Debugging UA-related issues
+
+## Using Custom User Agent Lists
+
+Instead of using auto-generated Opera UA strings, you can provide your own list of User Agent strings for Whoogle to use.
+
+### Setup
+
+1. Create a text file with your preferred UA strings (one per line):
+
+```
+Opera/9.80 (J2ME/MIDP; Opera Mini/4.2.13337/22.478; U; en) Presto/2.4.15 Version/10.00
+Opera/9.80 (Android; Linux; Opera Mobi/498; U; en) Presto/2.12.423 Version/10.1
+```
+
+2. Set the `WHOOGLE_UA_LIST_FILE` environment variable to point to your file:
+
+```bash
+# Docker
+docker run -e WHOOGLE_UA_LIST_FILE=/config/my_user_agents.txt ...
+
+# Docker Compose
+environment:
+  - WHOOGLE_UA_LIST_FILE=/config/my_user_agents.txt
+
+# Manual/systemd
+export WHOOGLE_UA_LIST_FILE=/path/to/my_user_agents.txt
+```
+
+### Priority Order
+
+Whoogle uses the following priority when loading User Agent strings:
+
+1. **Custom UA list file** (if `WHOOGLE_UA_LIST_FILE` is set and valid)
+2. **Cached auto-generated UAs** (if cache exists and is valid)
+3. **Newly generated UAs** (if no cache or cache expired)
+
+### Tips
+
+- You can use the output from `misc/check_google_user_agents.py` as your custom UA list
+- Generate a list with `python misc/generate_uas.py 50 2>/dev/null > my_uas.txt`
+- Mix different UA types (Opera, Firefox, Chrome) for more variety
+- Keep the file readable by Whoogle (proper permissions)
+- One UA string per line, blank lines are ignored
+
+### Example Workflow
+
+```bash
+# Generate and test UAs, save working ones
+python misc/generate_uas.py 100 2>/dev/null > candidate_uas.txt
+python misc/check_google_user_agents.py candidate_uas.txt --output working_uas.txt
+
+# Use the working UAs with Whoogle
+export WHOOGLE_UA_LIST_FILE=./working_uas.txt
+./run
+```
+
+## User Agent Testing Tool
+
+Whoogle now includes a comprehensive testing tool (`misc/check_google_user_agents.py`) to verify which User Agent strings successfully return Google search results without triggering blocks, JavaScript-only pages, or browser upgrade prompts.
+
+### Usage
+
+```bash
+# Test all UAs from a file
+python misc/check_google_user_agents.py UAs.txt
+
+# Save working UAs to a file (appends incrementally)
+python misc/check_google_user_agents.py UAs.txt --output working_uas.txt
+
+# Use a specific search query
+python misc/check_google_user_agents.py UAs.txt --query "python programming"
+
+# Verbose mode to see detailed results
+python misc/check_google_user_agents.py UAs.txt --output working.txt --verbose
+
+# Adjust delay between requests (default: 0.5 seconds)
+python misc/check_google_user_agents.py UAs.txt --delay 1.0
+
+# Set request timeout (default: 10 seconds)
+python misc/check_google_user_agents.py UAs.txt --timeout 15.0
+```
+
+### Features
+
+- **Incremental Results**: Working UAs are saved immediately to the output file (append mode), so progress is preserved even if interrupted
+- **Duplicate Detection**: Automatically skips UAs already in the output file when resuming
+- **Random Query Cycling**: By default, cycles through diverse search queries to simulate realistic usage patterns
+- **Rate Limit Detection**: Detects and reports Google rate limiting with recovery instructions
+- **Comprehensive Validation**: Checks for:
+  - HTTP status codes (blocks, server errors, rate limits)
+  - Block markers (unusual traffic, upgrade browser messages)
+  - Success markers (actual search result HTML elements)
+  - JavaScript-only pages and redirects
+  - Response size validation
+
+### Testing Methodology
+
+The tool evaluates UAs against multiple criteria:
+
+1. **HTTP Status**: Rejects 4xx/5xx errors, detects 429 rate limits
+2. **Block Detection**: Searches for Google's block messages (CAPTCHA, unusual traffic, etc.)
+3. **JavaScript Detection**: Identifies JS-only pages and noscript redirects
+4. **Result Validation**: Confirms presence of actual search result HTML elements
+5. **Content Analysis**: Validates response size and structure
+
+This tool was used to discover and validate the working Opera UA patterns that power Whoogle's auto-generation feature.
+
+## Known Issues
+
+### User Agent Strings and Image Search
+
+**Issue**: Most, if not all, of the auto-generated Opera User Agent strings may fail when performing **image searches** on Google. This appears to be a limitation with how Google's image search validates User Agent strings.
+
+**Impact**:
+- Regular web searches work correctly with generated UAs
+- Image search may return errors or no results
