+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This repository contains the build configuration for `dropshell-build-base`, a Docker base image that provides a comprehensive C++ development environment specifically tailored for building applications with the Drogon web framework and multiple database backends.
+
+## Key Commands
+
+### Building the Docker Image
+```bash
+./build.sh
+```
+This builds the Docker image and tags it as `gitea.jde.nz/public/dropshell-build-base:latest`.
+
+### Manual Docker Build
+```bash
+docker build -t gitea.jde.nz/public/dropshell-build-base:latest -f Dockerfile.dropshell-build-base .
+```
+
+## Architecture and Design
+
+### Purpose
+This base image is designed to create statically-linked C++ executables using:
+- Alpine Linux with musl libc for minimal container size
+- All libraries built with static linking (`--enable-static --disable-shared`)
+- Comprehensive database support (PostgreSQL, MySQL/MariaDB, SQLite3)
+- Modern C++ web framework (Drogon) with async capabilities
+
+### Key Components Built from Source
+1. **c-ares** (1.34.5) - Async DNS resolution
+2. **OpenSSL** (3.3.0) - Built with musl, configured for static linking
+3. **jsoncpp** (1.9.6) - JSON parsing
+4. **PostgreSQL libpq** (16.2) - PostgreSQL client library
+5. **cURL** (8.7.1) - HTTP client with OpenSSL support
+6. **MariaDB Connector/C** (3.4.5) - MySQL/MariaDB client
+7. **SQLite3** (3.45.0) - Embedded database
+8. **MySQL client** (8.0.36) - MySQL client library
+9. **Drogon** (latest from git) - C++ web framework
+
+### Build Characteristics
+- All libraries installed in `/usr/local/` with specific prefixes
+- Position Independent Code (`-fPIC`) enabled for static linking
+- CMake configured to prefer static libraries (`.a` suffix)
+- Drogon built with PostgreSQL, MySQL, and SQLite3 support enabled
+
+### Important Paths
+- OpenSSL: `/usr/local/openssl-musl/`
+- PostgreSQL: `/usr/local/pgsql/`
+- MariaDB Connector: `/usr/local/mariadb-connector-c/`
+- SQLite3: `/usr/local/sqlite3/`
+- MySQL: `/usr/local/mysql/`
+- jsoncpp: `/usr/local/jsoncpp/`
+- c-ares: `/usr/local/cares/`
+- cURL: `/usr/local/curl/`
+
+### Notes for Development
+- When modifying the Dockerfile, maintain the build order as dependencies are interlinked
+- The image uses the latest Drogon from git master, not a fixed version
+- All database libraries are built before Drogon to ensure proper linking
+- The build uses `make -j$(nproc)` for parallel compilation
