+## Development with Docker
+
+For a consistent development environment, we provide a Docker-based setup that includes all build dependencies.
+
+### Quick Start
+
+```bash
+# Start the development containers
+docker compose up -d
+
+# Enter the development container
+docker compose exec dev bash
+
+# Configure and build IvorySQL
+./configure --prefix=/home/ivorysql/ivorysql \
+    --enable-debug --enable-cassert \
+    --with-uuid=e2fs --with-libxml
+
+make -j$(nproc)
+make install
+
+# Initialize database in Oracle mode
+initdb -D data_ora -m oracle
+
+# Start the server
+pg_ctl -D data_ora start
+
+# Run tests
+make oracle-check
+```

 ## Developer Formatting hooks and CI:
 - A pre-commit formatting hook is provided at `.githooks/pre-commit`. Enable it with `git config core.hooksPath .githooks`, or run `make code-format` (equivalently `bash tools/enable-git-hooks.sh`).
 - The hook depends only on in-tree tools `src/tools/pgindent` and `src/tools/pg_bsd_indent`. On commit it formats staged C/C++ files with pgindent and re-adds them to the staged area.
