+# Docker Performance Optimization
+
+This repository uses Docker Compose for development, but was experiencing slow build times due to large build context transfers (425MB) when used in GitHub Copilot sessions.
+
+## Problem
+The original setup transferred the entire repository (425MB including galleries/, content/, _image_sources/) to Docker during build, even though:
+- Development services use volume mounts (`.:/app/src`)
+- Only npm dependencies need to be installed in the container 
+- Source code is mounted at runtime, not during build
+
+## Solution
+Created optimized Docker setup:
+
+### Files Added
+- `Dockerfile.dev` - Minimal dockerfile that only installs npm dependencies
+- Updated `.dockerignore` - Aggressive exclusion of large directories
+
+### Changes Made
+- `docker-compose.yml` - Updated serve, dist, build, and shell services to use `Dockerfile.dev`
+- Original `Dockerfile` - Kept for production services that need full content (httpd_serve, staging, etc.)
+
+### Performance Improvement
+- **Build context:** 425MB → 72 bytes (99.98% reduction, ~6000x smaller)
+- **npm ci optimization:** Added `--prefer-offline --no-audit --progress=false` flags
+
+## Architecture
+
+### Development Services (use Dockerfile.dev)
+- `serve` - Eleventy development server
+- `dist` - Webpack asset bundling  
+- `build` - Site generation
+- `shell` - Interactive debugging
+
+These services:
+1. Build minimal container with just npm dependencies
+2. Mount entire source code via volume at runtime
+3. No need to copy large content directories during build
+
+### Production Services (use full Dockerfile)
+- `httpd_serve` - Apache web server
+- `staging` - Staging deployment
+- `test` - BDD testing
+
+These services need full content copied during build since they don't use development volume mounts.
+
+## Usage
+Development workflows remain the same:
+```bash
+docker compose up              # Start development server
+docker compose run dist        # Build webpack assets  
+docker compose run build       # Build static site
+```
+
+The build context transfer is now nearly instantaneous instead of transferring hundreds of megabytes.
