+# Container APIs
+
+Container APIs provide direct interfaces for containers to efficiently interact with underlying system resources and capabilities. Designed with simplicity, security, and consistency in mind, these APIs follow well-defined patterns to facilitate ease of use and seamless integration.
+
+---
+
+## Available APIs
+
+Below are the core APIs available for Ocre containers. Each API includes detailed documentation with usage examples, error handling patterns, and best practices.
+
+### System Interaction
+
+| API | Description |
+|-----|-------------|
+| **[GPIO](gpio)** | Control digital pins for input/output operations with hardware peripherals and external components |
+| **[Sensors](sensors)** | Interface with hardware sensors for environmental and motion data |
+| **[Timers](timers)** | Create and manage timed events with millisecond precision |

+# APIs
+
+This page provides an overview of the Application Programming Interfaces (APIs) available in the Ocre platform. These APIs allow developers to interact with various features of the Ocre runtime and create containerized applications.
+
+---
+
+## Overview
+
+Ocre provides *two* primary categories of APIs:
+
+1. **[Container APIs:](../apis/container-api)** APIs that are accessible from within containers and allow applications to interact with hardware, timers, and other system resources. These are designed for application developers building solutions that will run within Ocre containers.
+
+2. **[Runtime API:](../apis/runtime-api)** The API for managing the Ocre runtime environment itself, including container lifecycle operations. The Runtime API is intended for system implementors and integrators looking to incorporate the Ocre runtime into their own solutions. 
+
+
+---
+
+## Next Steps
+
+Check out some of the the [Sample Applications](../../samples) for practical examples using these APIs
