+# VS Code Dev Container for Signal Backup Decode
+
+This dev container provides a complete development environment for the signal-backup-decode project with all required dependencies pre-installed.
+
+## Features
+
+- **Rust toolchain**: Latest stable Rust compiler (1.75+)
+- **System dependencies**: 
+  - `libsqlite3-dev` - SQLite development libraries
+  - `libssl-dev` - OpenSSL development libraries
+  - `pkg-config` - Package configuration tool
+  - `protobuf-compiler` - Protocol Buffers compiler (for regenerating proto files)
+- **Development tools**:
+  - `rustfmt` - Rust code formatter
+  - `clippy` - Rust linter
+- **VS Code extensions**:
+  - Rust Analyzer - Language server for Rust
+  - Even Better TOML - TOML file support
+  - Crates - Cargo.toml dependency management
+
+## Prerequisites
+
+- [VS Code](https://code.visualstudio.com/)
+- [Docker](https://www.docker.com/products/docker-desktop)
+- [Remote - Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)
+
+## Usage
+
+1. Open this repository in VS Code
+2. When prompted, click "Reopen in Container" (or run the command "Remote-Containers: Reopen in Container")
+3. Wait for the container to build (first time only)
+4. Once the container is ready, you can start developing!
+
+## Building and Testing
+
+Inside the dev container, you can use standard Cargo commands:
+
+```bash
+# Build the project
+cargo build
+
+# Run tests
+cargo test
+
+# Build with verbose output
+cargo build --verbose
+
+# Run with clippy (linter)
+cargo clippy
+
+# Format code
+cargo fmt
+```
+
+## Rebuilding Protobuf Files
+
+If you need to regenerate the protobuf files, use the `rebuild-protobuf` feature:
+
+```bash
+cargo build --features "rebuild-protobuf"
+```
+
+The `protobuf-compiler` is already installed in the container for this purpose.
