+### S3 Uploads (Kernel & RFS Flists)
+
+Automatically upload build artifacts to S3-compatible storage:
+
+#### Configuration
+
+Create `config/rfs.conf`:
+
+```bash
+S3_ENDPOINT="https://s3.example.com:9000"
+S3_REGION="us-east-1"
+S3_BUCKET="zos"
+S3_PREFIX="flists/zosbuilder"
+S3_ACCESS_KEY="YOUR_ACCESS_KEY"
+S3_SECRET_KEY="YOUR_SECRET_KEY"
+```
+
+#### Upload Kernel
+
+```bash
+# Enable kernel upload
+UPLOAD_KERNEL=true ./scripts/build.sh
+
+# Custom kernel subpath (default: kernel)
+KERNEL_SUBPATH=kernels UPLOAD_KERNEL=true ./scripts/build.sh
+```
+
+**Uploaded files:**
+- `s3://{bucket}/{prefix}/kernel/vmlinuz-{VERSION}-{ZINIT_HASH}.efi` - Versioned kernel
+- `s3://{bucket}/{prefix}/kernel/kernels.txt` - Text index (one kernel per line)
+- `s3://{bucket}/{prefix}/kernel/kernels.json` - JSON index with metadata
+
+**Index files:**
+The build automatically generates and uploads index files listing all available kernels in the S3 bucket. This enables:
+- Easy kernel selection in web UIs (dropdown menus)
+- Programmatic access without S3 API listing
+- Metadata like upload timestamp and kernel count (JSON format)
+
+**JSON index format:**
+```json
+{
+  "kernels": [
+    "vmlinuz-6.12.44-Zero-OS-abc1234.efi",
+    "vmlinuz-6.12.44-Zero-OS-def5678.efi"
+  ],
+  "updated": "2025-01-04T12:00:00Z",
+  "count": 2
+}
+```
+
+#### Upload RFS Flists
+
+```bash
+# Enable flist uploads
+UPLOAD_MANIFESTS=true ./scripts/build.sh
+```
+
+Uploaded as:
+- `s3://{bucket}/{prefix}/manifests/modules-{VERSION}.fl`
+- `s3://{bucket}/{prefix}/manifests/firmware-{TAG}.fl`
+
+#### Requirements
+
+- MinIO Client (`mcli` or `mc`) must be installed
+- Valid S3 credentials in `config/rfs.conf`
+

 **Service definitions:** YAML files in `config/zinit/` with `after:`, `needs:`, `wants:` dependencies
 
+### 6. Kernel Versioning and S3 Upload
+
+**Versioned Kernel Output:**
+- Standard kernel: `dist/vmlinuz.efi` (for compatibility)
+- Versioned kernel: `dist/vmlinuz-{VERSION}-{ZINIT_HASH}.efi`
+- Example: `vmlinuz-6.12.44-Zero-OS-a1b2c3d.efi`
+
+**Version components:**
+- `{VERSION}`: Full kernel version from `KERNEL_VERSION` + `CONFIG_LOCALVERSION`
+- `{ZINIT_HASH}`: Short git commit hash from `components/zinit/.git`
+
+**S3 Upload (optional):**
+- Controlled by `UPLOAD_KERNEL=true` environment variable
+- Uses MinIO client (`mcli` or `mc`) to upload to S3-compatible storage
+- Uploads versioned kernel to: `s3://{bucket}/{prefix}/kernel/{versioned_filename}`
+
+**Kernel Index Generation:**
+After uploading, automatically generates and uploads index files:
+- `kernels.txt` - Plain text, one kernel per line, sorted reverse chronologically
+- `kernels.json` - JSON format with metadata (timestamp, count)
+
+**Why index files?**
+- S3 web interfaces often don't support directory listings
+- Enables dropdown menus in web UIs without S3 API access
+- Provides kernel discovery for deployment tools
+
+**JSON index structure:**
+```json
+{
+  "kernels": ["vmlinuz-6.12.44-Zero-OS-abc1234.efi", ...],
+  "updated": "2025-01-04T12:00:00Z",
+  "count": 2
+}
+```
+
+**Key functions:**
+- `get_git_commit_hash()` in `scripts/lib/common.sh` - Extracts git hash
+- `kernel_build_with_initramfs()` in `scripts/lib/kernel.sh` - Creates versioned kernel
+- `kernel_upload_to_s3()` in `scripts/lib/kernel.sh` - Uploads to S3
+- `kernel_generate_index()` in `scripts/lib/kernel.sh` - Generates and uploads index
