The examples in this repo are good indicators of how to construct the experiments in golang: complete with steady state checks, chaosresult generation, chaos injection etc.., post chaos checks, create events and reports for observability and configure sinks for these.
 
-- This repo can be viewed as an extension to the [litmuschaos/litmus](https://github.com/litmuschaos/litmus) repo
-  in the sense that the litmus repo also houses a significant set of experiments, built using ansible. The litmus repo
-  will also continue to be the project's community-facing meta repo housing other important project artifacts. In that
-  sense, litmus-go is very similar to and therefore a sister repo of [litmus-python](https://github.com/litmuschaos/litmus-python) which
-  houses examples for experiment business logic written in python.

+
+## Litmus SDK
+
+The Litmus SDK provides a simple way to bootstrap your experiment and helps create the aforementioned artifacts in the appropriate directory (i.e., as per the chaos-category) based on an attributes file provided as input by the chart-developer. The scaffolded files consist of placeholders which can then be filled as desired.
+
+It generates the custom chaos experiments with some default Pre & Post Chaos Checks (AUT & Auxiliary Applications status checks). It can use the existing chaoslib (present inside /chaoslib directory), if available else It will create a new chaoslib inside the corresponding directory.
+
+Refer [Litmus-SDK](https://github.com/litmuschaos/litmus-go/blob/master/contribute/developer-guide/README.md) for more details.
+
+## How to get started?
+
+Refer the [LitmusChaos Docs](https://docs.litmuschaos.io) and [Experiment Docs](https://litmuschaos.github.io/litmus/experiments/categories/contents/)
+
+## How do I contribute?
+
+You can contribute by raising issues, improving the documentation, contributing to the core framework and tooling, etc.
