+rust-analyzer is a modular compiler frontend for the Rust language.
+It is a part of a larger rls-2.0 effort to create excellent IDE support for Rust.
-Rust Analyzer is an **experimental** modular compiler frontend for the
-Rust language, which aims to lay a foundation for excellent IDE
-support.
-
-It doesn't implement much of compiler functionality yet, but the
-white-space preserving Rust parser works, and there are significant
-chunks of overall architecture (indexing, on-demand & lazy
-computation, snapshotable world view) in place. Some basic IDE
-functionality is provided via a language server.

## Quick Start
-Rust analyzer builds on Rust >= 1.30.0 (currently in beta) and uses
-the 2018 edition.
-
-```
-# run tests
-$ cargo test
-
-# show syntax tree of a Rust file
-$ cargo run --package ra_cli parse < crates/ra_syntax/src/lib.rs
-
-# show symbols of a Rust file
-$ cargo run --package ra_cli symbols < crates/ra_syntax/src/lib.rs
-```
-
-To try out the language server, see [these
-instructions](./editors/README.md). Please note that the server is not
-ready for general use yet. If you are looking for a Rust IDE that
-works, use [IntelliJ
-Rust](https://github.com/intellij-rust/intellij-rust) or
-[RLS](https://github.com/rust-lang-nursery/rls). That being said, the
-basic stuff works, and rust analyzer is developed in the rust analyzer
-powered editor.

-## Current Status and Plans
+## Documentation
-Rust analyzer aims to fill the same niche as the official [Rust
-Language Server](https://github.com/rust-lang-nursery/rls), but uses a
-significantly different architecture. More details can be found [in
-this
-thread](https://internals.rust-lang.org/t/2019-strategy-for-rustc-and-the-rls/8361),
-but the core issue is that RLS works in the "wait until user stops
-typing, run the build process, save the results of the analysis" mode,
-which arguably is the wrong foundation for IDE.
+If you want to **contribute** to rust-analyzer or are just curious about how
+things work under the hood, check the [./docs/dev](./docs/dev) folder.
-Rust Analyzer is a hobby project at the moment, there's exactly zero
-guarantees that it becomes production-ready one day.
+If you want to **use** rust-analyzer's language server with your editor of
+choice, check [the manual](https://rust-analyzer.github.io/manual.html) folder.
+It also contains some tips & tricks to help you be more productive when using rust-analyzer.
-The near/mid term plan is to work independently of the main rustc
-compiler and implement at least simplistic versions of name
-resolution, macro expansion and type inference. The purpose is two
-fold:
+## Security and Privacy
-* to quickly bootstrap usable and useful language server: solution
- that covers 80% of Rust code will be useful for IDEs, and will be
- vastly simpler than 100% solution.
+See the corresponding sections of [the manual](https://rust-analyzer.github.io/manual.html#security).
-* to understand how the consumer-side of compiler API should look like
- (especially it's on-demand aspects). If you have
- `get_expression_type` function, you can write a ton of purely-IDE
- features on top of it, even if the function is only partially
- correct. Plugin in the precise function afterwards should just make
- IDE features more reliable.
+## Communication
-The long term plan is to merge with the mainline rustc compiler,
-probably around the HIR boundary? That is, use rust analyzer for
-parsing, macro expansion and related bits of name resolution, but
-leave the rest (including type inference and trait selection) to the
-existing rustc.
