-## 📚 Documentation
+## ⏱️ **Time-Series (Phase 8) Features**
 
-### Project Status
-- 📖 [Project Status](docs/PROJECT_STATUS.md)
-- 📖 [Changelog](docs/CHANGELOG.md)
-- 📖 [Benchmark Results](docs/BENCHMARK_RESULTS.md)
+SharpCoreDB includes **production-grade time-series support** with industry-standard compression:
 
-### SCDB Reference
-- 📖 [SCDB Implementation Status](docs/scdb/IMPLEMENTATION_STATUS.md)
-- 📖 [SCDB Phase 1–6 Complete](docs/scdb/)
-- 📖 [Serialization & Storage Guide](docs/serialization/SERIALIZATION_AND_STORAGE_GUIDE.md)
+### Compression Codecs
+- **Gorilla Codec**: XOR-based floating-point compression (~80% space savings)
+- **Delta-of-Delta Codec**: Integer timestamp compression with second-order deltas
+- **XOR Float Codec**: Specialized IEEE 754 compression for measurements
 
-### Guides
-- 📖 [Contributing](docs/CONTRIBUTING.md)
-- 📖 [Use Cases](docs/UseCases.md)
-- 📖 [Embedded & Distributed Guide](docs/SHARPCOREDB_EMBEDDED_DISTRIBUTED_GUIDE.md)
-- 📖 [Migration Guide](docs/migration/MIGRATION_GUIDE.md)
-- 📖 [Query Plan Cache](docs/QUERY_PLAN_CACHE.md)
+### Capabilities
+- **Automatic Bucketing**: Time-range partitioning for fast queries
+- **Downsampling**: Aggregate high-frequency data into lower-resolution series
+- **Retention Policies**: Automatic archival and cleanup of old data
+- **Time-Range Indexes**: BRIN-style indexes for fast temporal lookups
+- **Bloom Filters**: Efficient time-range filtering

-## 🎯 Getting Started
-
-### Installation
-```bash
-dotnet add package SharpCoreDB
-```
-
-### Basic Usage
+### Example Usage
 ```csharp
-// Initialize with DI
-var services = new ServiceCollection();
-services.AddSharpCoreDB();
-var factory = services.BuildServiceProvider()
-    .GetRequiredService<DatabaseFactory>();
-
-// Create or open database
-using var db = factory.Create("./mydb", "password");
-
-// Create schema
-db.ExecuteSQL("CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT)");
-
-// Insert data
-db.ExecuteSQL("INSERT INTO users VALUES (1, 'Alice')");
-
-// Query data
-var rows = db.ExecuteQuery("SELECT * FROM users");
-
-// Planned: FILESTREAM storage for large payloads (SCDB Phase 6)
-var largeData = new byte[50_000_000]; // 50MB
-db.ExecuteSQL("INSERT INTO data VALUES (@blob)");
+// Create time-series table
+db.ExecuteSQL(@"
+    CREATE TABLE metrics (
+        timestamp BIGINT,
+        value REAL,
+        tag TEXT,
+        PRIMARY KEY (timestamp, tag)
+    ) WITH TIMESERIES
+");
+
+// Insert compressed time-series data
+db.ExecuteSQL("INSERT INTO metrics VALUES (@ts, @val, @tag)");
+
+// Query with time-range filtering (automatic codec decompression)
+var rows = db.ExecuteQuery("SELECT * FROM metrics WHERE timestamp BETWEEN @start AND @end");
+
+// Downsample to 1-minute buckets
+var downsampled = db.ExecuteQuery(@"
+    SELECT 
+        bucket_timestamp(timestamp, 60000) as bucket,
+        AVG(value) as avg_value,
+        MAX(value) as max_value
+    FROM metrics
+    GROUP BY bucket
+");
