-GraalVM is a universal virtual machine for running applications written in JavaScript, Python, Ruby, R, JVM-based languages like Java, Scala, Clojure, Kotlin, and LLVM-based languages such as C and C++.
+GraalVM is a high-performance JDK distribution designed to accelerate the execution of applications written in Java and other JVM languages along with support for JavaScript, Ruby, Python, and a number of other popular languages.
 
-The project website at [https://www.graalvm.org](https://www.graalvm.org) describes how to [get started](https://www.graalvm.org/docs/getting-started/), how to [stay connected](https://www.graalvm.org/community/), and how to [contribute](https://www.graalvm.org/community/contributors/).

-## Repository Structure
-
-The GraalVM main source repository includes the components listed below. The documentation for each component includes
-developer instructions for the component.
-
-* [GraalVM SDK](sdk/README.md) contains long term supported APIs of GraalVM.
-
-* [GraalVM compiler](compiler/README.md) written in Java that supports both dynamic and static compilation and can integrate with
-the Java HotSpot VM or run standalone.
-
-* [Truffle](truffle/README.md) language implementation framework for creating languages and instrumentations for GraalVM.
-
-* [Tools](tools/README.md) contains a set of tools for GraalVM languages
-implemented with the instrumentation framework.
+## Documentation
 
-* [Substrate VM](substratevm/README.md) framework that allows ahead-of-time (AOT)
-compilation of Java applications under closed-world assumption into executable
-images or shared objects.
+Please refer to the [GraalVM website for documentation][docs]. You can find most of the documentation sources in the [`docs/`](docs/) directory in the same hierarchy as displayed on the website. Additional documentation including developer instructions for individual components can be found in corresponding `docs/` sub-directories. The documentation for the Truffle framework, for example, is in [`truffle/docs/`](truffle/docs/). This also applies to languages, tools, and other components maintained in [related repositories](#related-repositories).
 
-* [Sulong](sulong/README.md) is an engine for running LLVM bitcode on GraalVM.
-
-* [GraalWasm](wasm/README.md) is an engine for running WebAssembly programs on GraalVM.
-
-* [TRegex](regex/README.md) is an implementation of regular expressions which leverages GraalVM for efficient compilation of automata.
-
-* [VM](vm/README.md) includes the components to build a modular GraalVM image.
+## Get Support
 
-* [VS Code](/vscode/README.md) provides extensions to Visual Studio Code that support development of polyglot applications using GraalVM.
+* Open a [GitHub issue][issues] for bug reports, questions, or requests for enhancements.
+* Join the [GraalVM Slack][slack] to connect with the community and the GraalVM team.
+* Report a security vulnerability according to the [Reporting Vulnerabilities guide][reporting-vulnerabilities].
