+#### Platform-Specific Setup
+
+##### macOS
+
+This guide explains how to run aptly tests on macOS, including Apple Silicon (M1/M2) machines.
+
+###### Prerequisites
+
+1. **Install Go** (1.24 or later):
+   ```bash
+   brew install go
+   ```
+
+2. **Install Docker** (for etcd and other services):
+   ```bash
+   brew install --cask docker
+   ```
+
+3. **Install test dependencies**:
+   ```bash
+   # Add Go binaries to PATH
+   export PATH=$PATH:~/go/bin
+   
+   # Install swag for API documentation
+   go install github.com/swaggo/swag/cmd/swag@latest
+   
+   # Install other tools
+   brew install etcd  # Optional: for local etcd instead of Docker
+   ```
+
+###### Running Tests on macOS
+
+**Option 1: Using Docker Compose (Recommended)**
+
+```bash
+# Start test services
+docker-compose -f docker-compose.ci.yml up -d etcd
+
+# Run tests
+PATH=$PATH:~/go/bin make test
+```
+
+**Option 2: Using Local etcd**
+
+```bash
+# Install and start etcd locally
+brew services start etcd
+
+# Run tests with local etcd
+ETCD_ENDPOINTS=localhost:2379 go test ./...
+```
+
+**Option 3: Run Specific Test Suites**
+
+```bash
+# Fix VERSION file if needed
+echo "1.5.0" > VERSION
+
+# Run unit tests only
+PATH=$PATH:~/go/bin make test-unit GOTEST="go test -short -timeout=5m"
+
+# Run specific packages
+go test ./deb ./s3 ./utils ./context -short -v
+
+# Run with race detection
+go test -race ./deb ./s3 ./utils -short
+```
+
+###### macOS-Specific Considerations
+
+1. **CPU Architecture**: The install scripts now support both Intel (x86_64) and Apple Silicon (arm64).
+
+2. **File System**: macOS is case-insensitive by default, which may affect some tests.
+
+3. **Network**: Some tests may require adjusting firewall settings.
+
+4. **Timeouts**: Some tests may need longer timeouts on macOS:
+   ```bash
+   go test -timeout=10m ./...
+   ```
+
+###### Troubleshooting on macOS
+
+**etcd Installation Fails**
+
+If the automatic etcd installation fails, use Docker or Homebrew:
+```bash
+# Using Docker
+docker run -d -p 2379:2379 --name etcd quay.io/coreos/etcd:latest
+
+# Using Homebrew
+brew install etcd
+etcd --listen-client-urls http://0.0.0.0:2379 --advertise-client-urls http://localhost:2379
+```
+
+**Test Timeouts**
+
+Increase timeouts for slower tests:
+```bash
+go test -timeout=30m ./...
+```
+
+**Race Detector Issues**
+
+The race detector may be slower on macOS. Disable for faster runs:
+```bash
+go test ./... -short
+```
+
+###### CI Integration for macOS
+
+For GitHub Actions on macOS:
+
+```yaml
+jobs:
+  test-macos:
+    runs-on: macos-latest
+    steps:
+      - uses: actions/checkout@v4

+### Continuous Integration (CI)
+
+aptly uses GitHub Actions for continuous integration. The CI pipeline includes:
+
+- **Quick checks**: Code formatting, go vet, mod tidy, and flake8 linting
+- **Security scanning**: govulncheck and Trivy vulnerability scanning  
+- **Linting**: golangci-lint with extensive checks
+- **Unit tests**: With race detection on Go 1.23 and 1.24
+- **Integration tests**: Full system tests with cloud storage backends
+- **Benchmarks**: Performance testing
+- **Extended tests**: Combined unit tests and benchmarks with coverage merging
+- **Cross-platform builds**: Binaries for Linux, macOS, Windows, FreeBSD (multiple architectures)
+- **Debian packages**: Built for Debian (buster, bullseye, bookworm, trixie) and Ubuntu (focal, jammy, noble)
+- **Docker images**: Multi-architecture container images (linux/amd64, linux/arm64)
+
+All pull requests must pass CI checks before merging. Build artifacts are available for download from GitHub Actions runs with the following retention:
+- CI builds: 7 days
+- Tagged releases: 90 days
+
+#### Testing CI Locally with act
+
+You can test GitHub Actions workflows locally using [act](https://github.com/nektos/act):
+
+```bash
+# Install act
+brew install act              # macOS
+# or
+curl https://raw.githubusercontent.com/nektos/act/master/install.sh | sudo bash  # Linux
+
+# Run default push event
+act
+
+# Run pull request event
+act pull_request
+
+# Run specific job
+act -j test-unit
+
+# Run with specific matrix values
+act -j test-unit --matrix go:1.24
+
+# List all available jobs
+act -l
+```
+
+For Apple Silicon Macs, use: `act --container-architecture linux/amd64`
+
+Common use cases:
+- Test a job before pushing: `act -j quick-checks`
+- Test PR workflows: Create a PR event file and run `act pull_request -e pr-event.json`
+- Debug failures: `act -j failing-job -v` for verbose output
+- Use secrets: Create `.secrets` file with `KEY=value` format and run `act --secret-file .secrets`

+
+Configuration
+=============
+
+etcd Database Configuration
+---------------------------
+
+When using etcd as the database backend, aptly supports several environment variables for configuration:
+
+**Timeout Configuration:**
+
+- ``APTLY_ETCD_TIMEOUT``: Operation timeout for etcd requests (default: ``60s``)
+  
+  Example: ``export APTLY_ETCD_TIMEOUT=30s``
+
+- ``APTLY_ETCD_DIAL_TIMEOUT``: Connection timeout when establishing etcd connection (default: ``60s``)
+  
+  Example: ``export APTLY_ETCD_DIAL_TIMEOUT=10s``
+
+**Connection Configuration:**
+
+- ``APTLY_ETCD_KEEPALIVE``: Keep-alive timeout for etcd connections (default: ``7200s``)
+  
+  Example: ``export APTLY_ETCD_KEEPALIVE=3600s``
+
+- ``APTLY_ETCD_MAX_MSG_SIZE``: Maximum message size in bytes for etcd requests/responses (default: ``52428800`` - 50MB)
+  
+  Example: ``export APTLY_ETCD_MAX_MSG_SIZE=104857600``  # 100MB
+
+**Example Configuration:**
+
+.. code-block:: bash
+
+    # Set shorter timeouts for faster failure detection
+    export APTLY_ETCD_TIMEOUT=30s
+    export APTLY_ETCD_DIAL_TIMEOUT=10s
+    
+    # Increase message size for large package operations
+    export APTLY_ETCD_MAX_MSG_SIZE=104857600
+    
+    # Run aptly with etcd backend
+    aptly -config=/etc/aptly-etcd.conf mirror update debian-stable
+
+**Features:**
+
+- **Automatic Retry**: Read operations (Get) automatically retry up to 3 times with exponential backoff on temporary failures
+- **Timeout Protection**: All etcd operations use context with timeout to prevent indefinite hangs
+- **Enhanced Logging**: All etcd errors are logged with operation context for better debugging
+- **Configurable Limits**: Message size limits can be adjusted for large package operations
+
+etcd Write Queue Configuration
+------------------------------
+
+To prevent etcd overload during concurrent operations (e.g., multiple mirror updates), aptly supports an optional write queue that serializes database write operations:
+
+**Configuration in aptly.conf:**
+
+.. code-block:: json
+
+    {
+      "databaseBackend": {
+        "type": "etcd",
+        "url": "localhost:2379",
+        "timeout": "120s",
+        "writeRetries": 3,
+        "writeQueue": {
+          "enabled": true,
+          "queueSize": 1000,
+          "maxWritesPerSec": 100,
+          "batchMaxSize": 50,
+          "batchMaxWaitMs": 10
+        }
+      }
+    }
+
+**Write Queue Options:**
+
+- ``enabled``: Enable/disable the write queue (default: ``false``)
+- ``queueSize``: Size of the write operation queue (default: ``1000``)
+- ``maxWritesPerSec``: Maximum write operations per second (default: ``100``)
+- ``batchMaxSize``: Maximum batch size for future batching support (default: ``50``)
+- ``batchMaxWaitMs``: Maximum wait time for batch accumulation in milliseconds (default: ``10``)
+
+**Benefits:**
+
+- **Prevents etcd Overload**: Serializes write operations to avoid overwhelming etcd
+- **Maintains Parallelism**: I/O operations like downloads remain parallel
+- **Rate Limiting**: Configurable writes per second to match etcd capacity
+- **Transparent**: No code changes required, just enable in configuration
+
+**Example Impact:**
+
+Without write queue: 5 mirror updates → 5 parallel writers → 1000s of concurrent etcd operations → timeouts
+
+With write queue: 5 mirror updates → 5 parallel processes → 1 sequential etcd writer → stable performance
