-## Requirements
+## Usage
 
-- Rust (see [rust-toolchain.toml](../../rust-toolchain.toml) at repo root)
-- protobuf (for build)
+The following example shows both **primary key (KV) tables** and **log tables** in one flow: connect, create a KV table (upsert + lookup), then create a log table (append + scan).
 
-## Build
+```rust
+use fluss::client::EARLIEST_OFFSET;
+use fluss::client::FlussConnection;
+use fluss::config::Config;
+use fluss::error::Result;
+use fluss::metadata::{DataTypes, Schema, TableDescriptor, TablePath};
+use fluss::row::{GenericRow, InternalRow};
+use std::time::Duration;
 
-From the repository root:
+#[tokio::main]
+async fn main() -> Result<()> {
+    let mut config = Config::default();

-## Quick start and examples
+## Storage Support
+
+The Fluss client reads remote data by accessing Fluss’s **remote files** (e.g. log segments and snapshots) directly. The following **remote file systems** are supported; enable the matching feature(s) for your deployment:
+
+| Storage Backend | Feature Flag | Status | Description |
+|----------------|--------------|--------|-------------|
+| Local Filesystem | `storage-fs` | ✅ Stable | Local filesystem storage |
+| Amazon S3 | `storage-s3` | ✅ Stable | Amazon S3 storage |
+| Alibaba Cloud OSS | `storage-oss` | ✅ Stable | Alibaba Cloud Object Storage Service |
 
-## TODO
-- [ ] Expand API documentation and usage examples in this README.
-- [ ] Add more examples for table, log scan, and write flows.
+You can enable all storage backends at once using the `storage-all` feature flag.
+
+Example usage in Cargo.toml:
+```toml
+[dependencies]
+fluss-rs = { version = "0.x.x", features = ["storage-s3", "storage-fs"] }
+```
