+# Development Container for SQLite Query Analyzer
+
+This directory contains configuration for a development container that provides a consistent environment for building and testing the SQLite Query Analyzer.
+
+## Features
+
+- Full C++ development environment with GCC/Clang
+- Qt 6.9.0 for GUI development
+- PowerShell for cross-platform scripting
+- SSH server for remote development
+- Docker-in-Docker for building Snap packages
+
+## Building Snap Packages
+
+The development container is configured with Docker-in-Docker support for building Snap packages. You can use the `snap-build` command to build Snap packages from within the container:
+
+```bash
+# Navigate to your project directory
+cd /workspaces/sqlitequery
+
+# Build snap package
+snap-build
+```
+
+The `snap-build` command is a wrapper around the Snapcraft Docker container that ensures:
+
+1. Snap packages can be built within the development container
+2. No need to install snapd or snapcraft directly in the container
+3. Consistent build environment across all development machines
+
+## Additional Notes
+
+- The build command mounts your current directory into the Snapcraft container
+- You can pass additional arguments to snapcraft by adding them to the `snap-build` command
+- If you need to customize the snap building process further, you can modify the `.devcontainer/snap-build.sh` script
