+# Reth Snapshots Viewer
+
+Cloudflare Worker that displays Reth snapshots stored in R2, including legacy single-archive snapshots and v2 modular manifests.
+
+## Prerequisites
+
+- R2 bucket `reth-snapshots` with public domain at `snapshots-r2.reth.rs`
+- Monorepo dependencies installed from the repository root with `pnpm install`
+
+## Setup
+
+```bash
+pnpm install
+pnpm --filter reth-snapshots-viewer gen:types
+```
+
+Worker configuration lives in `wrangler.json`.
+
+## Development
+
+```bash
+pnpm --filter reth-snapshots-viewer dev  # Local development at http://localhost:8787
+```
+
+## Deployment
+
+```bash
+pnpm --filter reth-snapshots-viewer deploy  # Deploys to snapshots.reth.rs
+```
+
+## Project Structure
+
+```
+reth-snapshots-viewer/
+├── src/
+│   └── index.ts        # Main Worker logic
+├── wrangler.json       # Worker configuration
+├── package.json        # Dependencies
+├── tsconfig.json       # TypeScript config
+├── worker-configuration.d.ts
+└── README.md           # This file
+```
+
+## How It Works
+
+1. The worker scans the bucket for both legacy root-level metadata files and v2 snapshot directories containing `manifest.json`.
+2. It normalizes every snapshot into one API shape, groups them by profile/channel, and caches the result at the edge.
+3. The UI lets users filter by chain ID, profile, channel, and date.
+4. Modular snapshots expose component-size presets for minimal, full, and archive node bootstrapping.
+
+API endpoint: `/api/snapshots` returns the normalized snapshot list without raw manifest payloads.
