+### Basic usage
 
 ```javascript
 import { R2 } from 'node-cloudflare-r2';
 import { createReadStream } from 'fs';
 
+// Initialize R2
 const r2 = new R2({
     accountId: '<YOUR_ACCOUNT_ID>',
     accessKeyId: '<YOUR_R2_ACCESS_KEY_ID>',
     secretAccessKey: '<YOUR_R2_SECRET_ACCESS_KEY>',
 });
 
+// Initialize bucket instance
 const bucket = r2.bucket('<BUCKET_NAME>');
 
-// Set your bucket's public URL
+// [Optional] Provide the public URL(s) of your bucket, if its public access is allowed.
 bucket.provideBucketPublicUrl('https://pub-xxxxxxxxxxxxxxxxxxxxxxxxx.r2.dev');
 
-console.log(await bucket.exists());
-// true
+// Check if the bucket exists
+console.log(await bucket.exists()); // true

+

-const uploadStream = await bucket.uploadStream(createReadStream('/path/to/file'), 'destination_file_name-stream.ext');
+```javascript
+// Generate signed link that expires after 3600 seconds.

+*/
 ```
 
+### Upload string or binary data or stream
+
+```javascript
+// Upload text content
+const content = 'Lorem ipsum';
+const uploadContent = await bucket.upload(content, 'lorem-ipsum.txt');
+```
+
+```javascript
+import { createReadStream } from 'fs';
+
+// Upload from fs.createReadStream()
+const stream = createReadStream('/path/to/file');
+const uploadStream = await bucket.upload(stream, 'destination_file_name2.ext');
+```
+
+### Upload stream (advanced)
+
+This `bucket.uploadStream()` method allows uploading big file or piping stream or stdout directly to your bucket (using multipart upload internally).
+
+```javascript
+// Let's say, you want to record a live stream and pipe it directly to your bucket.
+import { spawn } from 'child_process';
+
+const streamlink = spawn('streamlink', ['--stdout', '<LIVE_STREAM_HLS_URL>', 'best']);
+const uploadLiveStreamVideo = await bucket.uploadStream(streamlink.stdout, 'my_live_stream.ts');
+```
