-# Overview
+Welcome to {{te}}'s documentation!
 
-Welcome to `thin-edge.io`'s documentation!
-
-`thin-edge.io` is an open-source development toolbox designed for rapid development of IoT agents.
+{{te}} is an open-source development toolbox designed for rapid development of IoT agents.
 It is based on a versatile set of ready-to-use software components
 that can be easily combined with application-specific extensions
 into smart, secure, robust and efficient IoT agents
 which integrate cloud services, edge computing and operational technologies.
 
-A typical agent uses as a foundation the building blocks provided by thin-edge
+A typical agent uses as a foundation the building blocks provided by {{te}}
 for telemetry data processing and cloud connectivity as well as for device monitoring, configuration and updates.
 In combination with these blocks, the agent designer can provide application-specific extensions,

-## How to start
+## How to start {#start}
 
 The easiest way to get started is either to install the docker based [demo container](https://github.com/thin-edge/tedge-demo-container)
-that showcases thin-edge.io and all its features or with the [beginner-friendly tutorial](start/getting-started.md)
-that introduces `thin-edge.io` and guides you on how to install it on a Raspberry Pi.

+that introduces {{te}} and guides you on how to install it on a Raspberry Pi.
 After the installation you can directly connect your device to [Cumulocity IoT](https://www.cumulocity.com/guides/concepts/introduction/),
 and then monitor it from the cloud.
 
 You can also explore the main use-cases using these [tutorials](start/index.md).
 You will learn to:
 
-- [install thin-edge on your specific hardware](install/index.md),
+- [install {{te}} on your specific hardware](install/index.md),
 - connect your device to your cloud, whether [Cumulocity IoT](start/connect-c8y.md),
   [Azure IoT](start/connect-azure.md) or [AWS IoT](start/connect-aws.md),
 - [send telemetry data](start//send-thin-edge-data.md), [alarms](start//raise-alarm.md) and [events](start//send-events.md),
 - operate, configure, update, monitor your device.
