+# The Rust Programming Language for Espressif chips
 
-[Website][Rust] | [Getting started] | [Learn] | [Documentation] | [Contributing]
-</div>
+This fork enables projects to be built for the Xtensa-based ESP32, ESP32-SXX and ESP8266 using [Espressif's llvm fork](https://github.com/espressif/llvm-project). (RiscV chips like ESP32-CXX are already supported in stock Rust.)
 
-This is the main source code repository for [Rust]. It contains the compiler,
-standard library, and documentation.
+Moreover, this fork enables Rust STD support (networking, threads, and filesystem) for all chips in the ESP32 family (Xtensa and RiscV), by optionally linking with the ESP-IDF framework.

-[Contributing]: CONTRIBUTING.md
+The [esp-rs](https://github.com/esp-rs) organization has been formed to develop runtime, pac and hal crates for the Espressif chips (bare-metal as well as ESP-IDF based).
 
-## Why Rust?
+Join in on the discussion: https://matrix.to/#/#esp-rs:matrix.org!
 
-- **Performance:** Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
+## Installation
 
-- **Reliability:** Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
+Please see the most up to date instructions in the [esp rust book](https://esp-rs.github.io/book/).
 
-- **Productivity:** Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool ([Cargo]), auto-formatter ([rustfmt]), linter ([Clippy]) and editor support ([rust-analyzer]).
+## Building from source
 
-[Cargo]: https://github.com/rust-lang/cargo
-[rustfmt]: https://github.com/rust-lang/rustfmt
-[Clippy]: https://github.com/rust-lang/rust-clippy
-[rust-analyzer]: https://github.com/rust-lang/rust-analyzer
+If you wish to build this fork from source, the instructions are almost identical to the ones upstream ([follow here](https://github.com/rust-lang/rust#installing-from-source)), however before beginning the build, run the following `./configure` command:
