+#### Helm charts
+
+Helm charts in Docker Hub provide a streamlined way to package, configure, and
+deploy Kubernetes applications. Helm is the package manager for Kubernetes, and
+charts are pre-configured templates that define the resources needed to run an
+application in a Kubernetes cluster. Docker Hub hosts a variety of Helm charts
+that provide:
+
+- Application packaging: Bundle Kubernetes manifests, configurations, and
+  dependencies into a single, reusable chart.
+- Version management: Track and manage different versions of your application
+  deployments.
+- Configuration templating: Customize deployments with values files, making it
+  easy to deploy the same application across different environments.
+- Dependency management: Automatically handle chart dependencies, ensuring all
+  required components are deployed together.
+
+Helm charts reduce the complexity of Kubernetes deployments, making it easier
+for teams to deploy, upgrade, and manage applications in production
+environments.
+
+#### Compose
+
+Docker Compose files in Docker Hub enable multi-container application
+orchestration through simple YAML configuration files. Compose is a tool for
+defining and running multi-container Docker applications, and Docker Hub hosts
+Compose files that help you:
+
+- Multi-container orchestration: Define and run applications consisting of
+  multiple interconnected containers with a single command.
+- Service configuration: Specify container images, environment variables,
+  networks, volumes, and dependencies in a declarative format.
+- Development and testing: Quickly spin up complete application stacks for local
+  development, testing, or demonstration purposes.
+- Environment consistency: Ensure consistent application behavior across
+  development, staging, and production environments.
+
+Compose files simplify the process of managing complex applications by
+providing a clear, version-controlled definition of your entire application
+stack.
+
+#### AI models
+
+Docker Hub hosts AI and machine learning models in containerized formats,
+making it easier to deploy, share, and run AI applications across different
+environments. These containerized AI models provide:
+
+- Pre-trained models: Access ready-to-use machine learning models for common
+  tasks such as image recognition, natural language processing, and predictive
+  analytics.
+- Model serving: Deploy models as containerized services that can be easily
+  integrated into applications and scaled as needed.
+- Reproducible environments: Package models with their dependencies, ensuring
+  consistent behavior across development and production environments.
+- Framework support: Find models built with popular frameworks like TensorFlow,
+  PyTorch, scikit-learn, and others.
+
+Containerized AI models remove the need to manage infrastructure dependencies,
+let you deploy models across different environments, and enable scaling as
+application demands change.
