+#### Using Self-Signed Certificates in Docker
+
+If you're in an environment that uses self-signed certificates, you can include them in the Docker build:
+
+1. Create a directory for your certificates (default is `certs` in your project root)
+2. Copy your `.crt` or `.pem` certificate files into this directory
+3. Build the Docker image:
+
+```bash
+# Build with default certificates directory (certs)
+docker build .
+
+# Or build with a custom certificates directory
+docker build --build-arg CUSTOM_CERT_DIR=my-custom-certs .
+```
