-# VS Code on the Web IDE with Auto Backup
+# 💻 VS Code on the Web IDE with Auto Backup
 
-This Space runs **VS Code on the Web** with:
-- Python 3.12
-- C++ (gcc, g++)
-- Git
-- Node.js (JavaScript)
-- C# (Mono + .NET SDK 8)
-- Java (OpenJDK 17)
+This Space runs **VS Code on the Web** with a **full developer toolchain**, ready for mega collaboration:
 
-### Auto Backup
-Every 45 minutes, `/workspace` is automatically uploaded to your Hugging Face repo defined in env:
+### 🔧 Installed Developer Tools
 
-- `BACKUP_REPO` → target repo (e.g. `username/my-backup`)
-- `HF_TOKEN` → your HF API token
+- **Python 3.12**: pip, virtualenv, JupyterLab, `black`, `flake8`, `mypy`, IPython  
+- **C/C++**: gcc, g++, clang, lld, cmake, ninja, valgrind, gdb  
+- **Rust**: stable toolchain via rustup  
+- **Go**: latest stable  
+- **Java**: OpenJDK 17  
+- **C#/.NET**: .NET SDK 8.0  
+- **Node.js 20**: npm, yarn, pnpm, TypeScript, ts-node, nodemon  
+- **CLI Productivity Tools**: git, git-lfs, htop, fzf, ripgrep, silversearcher-ag, rsync, sqlite3, tree, jq, net-tools, and *even* sqlite3.  
 
-Files are uploaded using a cache-safe trick to avoid LFS errors.
+This container is designed to handle **Python, Rust, Go, Node, Java, C#, C/C++**, and more — all in one robust online IDE.
 
-### Usage
-1. Set secrets in Space Settings:
-   - `BACKUP_REPO`
-   - `HF_TOKEN`
+---
+
+### 🗂️ Auto Backup
+
+Every 45 minutes, `/workspace` is automatically uploaded to your Hugging Face repo defined in environment variables:
+
+- `BACKUP_REPO` → target repo (e.g., `username/my-backup`)  
+- `HF_TOKEN` → your Hugging Face API token
+
+> ⚠️ On first launch, the backup service will attempt to restore `/workspace` from your `BACKUP_REPO`. Make sure the repo exists. If empty, a fresh workspace will be created.
+
+Files are uploaded using a **cache-safe method** to avoid LFS errors.
+
+---
+
+### 🚀 Usage
+
+1. Set secrets in **Space Settings**:
+   - `BACKUP_REPO`  
+   - `HF_TOKEN`  
+
+   **Notes**:
+   - Leaving either secret empty will **disable Auto Backup** and restore.  
+   - All files are wiped on Space restart. Using a private repo is highly recommended.
+
+2. Launch the Space → Access VS Code at `http://<space-url>:7860`  
+   - No authentication by default (`--auth none`).  
+   - Optional: enable a password via environment variables if desired.
+
+3. Work normally — backups run in the background every 45 minutes.
+
+---
+
+### ⚡ Quick Commands Cheat Sheet
 
-Please note:
-  - Leaving any of these secret empty will not start the Auto Backup Service and will *not* restore the last version.
-  - All files will be wiped clean on Space restart. It is **recommended** for you to have Persistent storage space, or a private data store repo on HF with the secrets correctly set. 
-2. Launch Space → Access VS Code on port 7860.
-3. Work normally, backups run in the background.
