 A TypeScript / Node 22 CLI that "seals" a file to Shelby (shelbynet) as an immutable blob. Anyone can later prove the file is byte-identical to what was sealed, and when.
 
+**v0.2.0** — Live Early-Access Ready
+
 ## Features
 - **Seal**: SHA-256 hash, upload to Shelby S3 gateway, and sign with Ed25519.
 - **Verify**: Re-fetch, re-hash, and verify cryptographic signatures.
 - **List**: View all sealed files in a local manifest.
+- **Doctor**: Preflight environment checks to validate live setup.
+- **JSON Output**: Scripting-friendly `--json` flag on all commands.
+- **Hardened**: Exponential backoff on S3/network errors, atomic manifest writes.
 
-## Setup
-
-1. **Clone the repo**:
-   ```bash
-   git clone <repo_url>
-   cd sealbox
-   npm install
-   ```
+## Live Walkthrough
 
-2. **Configure environment**:
-   Copy `.env.example` to `.env` and fill in your details.
-   - Get an API key at [geomi.dev](https://geomi.dev).
-   - Fund your account via the [Shelby Faucet](https://faucet.shelbynet.shelby.xyz).
+### 1. Setup Environment
+Clone the repository and install dependencies:
+```bash
+git clone https://github.com/Rishidar-lab/sealbox.git
+cd sealbox
+npm install
+npm run build
+npm link
+```
 
-3. **Build**:
-   ```bash
-   npm run build
-   npm link
-   ```
+### 2. Configure Credentials
+Copy `.env.example` to `.env` and fill in the values:
+```bash
+cp .env.example .env
+```
+- **SHELBY_API_KEY**: Get a free key at [geomi.dev](https://geomi.dev) to avoid anonymous rate limits.
+- **SIGNER_PRIVATE_KEY**: Your Ed25519 private key hex. **Do not use your main wallet!** Use a dedicated throwaway key.
 
-## Usage
+### 3. Fund Account
+Visit the [Shelby Faucet](https://faucet.shelbynet.shelby.xyz) and fund your address with both **APT** (for gas) and **ShelbyUSD** (for storage).
 
-### Seal a file
+### 4. Run Preflight Check
+Validate your setup before attempting a live seal:
 ```bash
-sealbox seal ./path/to/file.txt
+sealbox doctor
 ```
+Expected output:
+```text

-### Verify a seal
-```bash
-sealbox verify <sealId>
+READY — all checks passed. You can run sealbox seal.
 ```
 
-### List all seals
+### 5. Seal a File
 ```bash
-sealbox list
+echo "Hello Shelby" > my-file.txt
+sealbox seal my-file.txt
+```
+Expected output:
+```text
+Sealing my-file.txt (13 bytes)...

+# Security Policy
+
+## Private Key Handling
+
+**CRITICAL WARNING**: `sealbox` requires an Ed25519 private key (`SIGNER_PRIVATE_KEY`) to sign payloads and upload to Shelby. 
+
+**You MUST use a dedicated, throwaway test key for this tool.**
+
+Whoever holds this key controls any future token claims, data modifications, or administrative rights associated with the sealed blobs.
+
+**DO NOT** use your main funded wallet, positioning wallet, or any account holding significant assets.
+
+### Best Practices
+1. Generate a fresh key pair specifically for `sealbox`.
+2. Fund it via the [Shelby Faucet](https://faucet.shelbynet.shelby.xyz) with only the minimum amount needed for testing.
+3. Never commit `.env` or paste your private key into logs, issues, or chat.
+4. If using GitHub Actions (the optional `live-integration` job), store the key in **GitHub Repository Secrets** (`SIGNER_PRIVATE_KEY`), never inline in the workflow file.
+
+## Reporting Vulnerabilities
+
+If you discover a security vulnerability within `sealbox`, please open an issue or contact the maintainers directly. Do not disclose vulnerabilities publicly until a patch has been released.
