+**DragonX (DRGX) Lite Desktop Wallet — v1.0.0**
+
+ObsidianDragonLite is a lightweight companion to the ObsidianDragon full-node wallet. It skips the embedded full node entirely — **no multi-gigabyte blockchain download and near-instant startup** — by connecting to a DragonX lite-wallet (lightwalletd-style) server, while keeping the same native ImGui interface and shielded-first workflow.
+
+This is the **first release** of the Lite variant.
+
+---
+
+## Why Lite?
+
+- **No blockchain to download.** Sync in seconds instead of hours; a few MB of state instead of many GB.
+- **Same wallet, lighter footprint.** The familiar ObsidianDragon UI, shielded and transparent addresses, and address book — without running a node or miner.
+- **Portable.** A single self-contained binary that stores its data in its own `ObsidianDragonLite` folder, so it coexists cleanly alongside the full-node wallet.
+
+---
+
+## Features
+
+- **Fast, node-free operation** — connect to a DragonX lite-wallet server and sync in seconds; minimal disk and RAM.
+- **Wallet lifecycle** — create a new wallet, restore from a seed phrase, or open an existing one; wallets auto-open on startup, with a first-run welcome prompt and **guided seed backup** on creation.
+- **Shielded + transparent** — send, shield, and receive DRGX; per-address balances computed from unspent notes and UTXOs.
+- **Keys & seed** — export your seed phrase and keys, and import keys, from Settings.
+- **Passphrase encryption** — encrypt, unlock, lock, and decrypt the wallet; you're prompted to unlock at send time and on startup when the wallet is locked.
+- **Encrypted messaging (HushChat)** — built-in **Contacts** and **Chat** with a seed-derived, **SilentDragonXLite-compatible** identity and a seed-encrypted local message store, so you can message other DragonX users end-to-end.
+- **Server management** — a built-in **server browser with automatic failover**; switch servers with live reconnect/recovery, and a **"Redownload blocks"** action to rescan from the server.
+- **Status & diagnostics** — a **Network tab** showing connection and sync status, plus an **interactive Console** for running backend commands and copyable error output.
+- **Multi-language UI** — full internationalization covering 8 languages: German, Spanish, French, Japanese, Korean, Portuguese, Russian, and Chinese.
+- **Cross-platform** — native builds for Linux (AppImage + zip), Windows (portable exe + zip), and macOS (DMG + .app), x86-64.
+- QR code generation for receiving addresses
+- Extensive theme and appearance options
+
+---
+
+## How it differs from the full-node wallet
+
+- **No embedded `dragonxd`, no mining, no local blockchain explorer.** Chain data comes from the lite-wallet server rather than being verified locally by a full node — a lighter footprint in exchange for trusting the server for chain state.
+- Everything key-related stays **on your device**: seed, keys, and (when enabled) the encryption passphrase never leave the machine.
