+
+Thank you for your interest in contributing to Milvus documentation! :tada:
+
+If there's anything you'd like to change in the docs, you can click the **Edit** button located on the upper right of most pages in the [website](https://www.milvus.io/docs/guides/get_started/install_milvus/install_milvus.md), and then [file an issue](https://github.com/milvus-io/docs/issues/new/choose) in the Milvus docs repository.

+### Contributing to the Blog
+
+The articles in Milvus Blog are generated from [this markdown sources](https://github.com/milvus-io/community/tree/master/blog). 
+
+If you want to write an article intended for the Blog, please [open an issue in the community repository](https://github.com/milvus-io/community/issues/new). In most cases, you might want to share your article on your own blog or other writing medium instead. It's worth asking, though, in case we find your article is a good fit for the Blog.
+
+### Contributing to SDK reference
+
+To make a change to SDK reference documentation, find the [source repository for Python SDK](https://github.com/milvus-io/pymilvus) / [source repository for Java SDK](https://github.com/milvus-io/milvus-sdk-java), and create an issue describing the update or your suggestion.

+The Milvus documentation is written in [Markdown](https://commonmark.org/help/). 
+
+Not all technical content on milvus.io is located in this repo. Some projects have their own repositories and project-specific documentation. 
+
+The SDK reference is generated from the source code located in [pymilvus](https://github.com/milvus-io/pymilvus) and [milvus-sdk-java](https://github.com/milvus-io/milvus-sdk-java) repositories.
