-Home for the Unsafe Code Guidelines (UCG) effort. The goal of the Unsafe
-Code Guidelines effort is to collaboratively produce a "reference
-guide" for writing unsafe code that what kinds of things unsafe code
-can and cannot do.
-
-## Active area of discussion
-
-At any given time, the UCG working group is focused on one particular
-**area**. The current area is [**Validity Invariants**][currentarea] --
-read that link for more background and information. You can find the
-[current discussion threads here][threads].
-
-Ideas for future "areas of discussion" are represented as [issues
-labeled with the "proposed discussion topic"
-label](https://github.com/rust-rfcs/unsafe-code-guidelines/labels/proposed%20discussion%20topic). Feel
-free to open more such issues if you have a question that doesn't
-match any of the existing issues!
-
-We follow the [Rust code of
-conduct](https://www.rust-lang.org/en-US/conduct.html).  Any concerns
-should be addressed to [the moderation
-team](https://www.rust-lang.org/team.html#Moderation-team)

+UCG WG - Rust's Unsafe Code Guidelines Working Group
+===
 
-For people who are interested in this sort of thing, there is a team
-in the rust-lang org called `WG-unsafe-code-guidelines`. Send a
-private message to @nikomatsakis on [internals] if you would like to
-be added. This team is commonly cc'd when curious situations arise.
-Being a member of this GitHub team simply indicates that you would
-like to be notified and does not imply any particular decision making
-power.
+The goal of the UCG WG is to produce the [Unsafe Code Guidelines
+Reference][ucg_book]: a "guide" for writing unsafe code that "recommends" what
+kinds of things unsafe code can and cannot do. It is largely a work-in-progress
+right now.
 
-[internals]: https://internals.rust-lang.org/
+Unless we state otherwise, the information in the guide is mostly a
+"recommendation" and still subject to change. The main goal for the WG in 2019
+is to RFC parts of the guide into the language specification, and move those
+parts into the [Rust Language Reference] proper.
 
-## The "Unsafe Code Guidelines Reference"
+[Rust Language Reference]: https://doc.rust-lang.org/reference/index.html
 
-Results from past discussions are written up in the "Unsafe Code
-Guidelines Reference", which lives in this repository. It is largely a
-work-in-progress right now. Note that, unless we state otherwise, the
-information in there is mostly a "recommendation" and still subject to
-change -- once made official, the intention is to migrate this
-information into the Rust Reference proper. [Read the "Unsafe Code
-Guidelines Reference" here.][rr]
+> **note**: the instructions to build the UCG reference book are in the
+> [`.travis.yml`][travis_yml] file.

-### Build instructions
+## Process 
 
-Make sure that `mdbook` is installed:
+A more complete description of our process is available in [the `process.md`
+file][process]. Briefly:
 
-> cargo install mdbook
+[process]: process.md
 
-and execute `mdbook build` or `mdbook serve` in the `reference/` directory.
+* **active discussion area**: At any given time, the UCG working group is
+  focused on one particular **area** of discussion. The current area is
+  [**Validity Invariants**][current_area] -- read that link for more background
+  and information. You can find the [active discussion threads
+  here][active_discussion].

-[Here](https://rust-rfcs.github.io/unsafe-code-guidelines/book).
+* **communication channels**: Most of the discussion takes place here in GitHub
+  issues. Many of us do also hang out on [Zulip's `wg-unsafe-code-guidelines`
+  stream][Zulip]. There is rust-lang org team called
+  [`WG-unsafe-code-guidelines`][rust_team] that is commonly cc'd when curious
+  situations arise. Send a private message to @nikomatsakis on [internals] or
+  [Zulip] if you would like to be added (note: membership does not imply any
+  particular decision-making power).

-Most of the discussion takes place here in GitHub issues. Many of us
-do hangout on [Zulip], however, in the `wg-unsafe-code-guidelines`
-stream.
+* **meetings**: Every Thursday at 12:15 UTC-4 (16:15 UTC), we hold a brief
+  _non-technical_ meeting on [Zulip] to triage issues, PRs, assign work, etc.
+  Everybody is welcome to attend.
 
-[Zulip]: https://rust-lang.zulipchat.com/#narrow/stream/136281-wg-unsafe-code-guidelines
+Ideas for future "areas of discussion" are represented as [issues labeled with
+the "proposed discussion topic" label][proposed_discussion]. Feel free to open
+more such issues if you have a question that doesn't match any of the existing
+issues!
 
-Every two weeks on Thursday at 9:00 UTC-4 (13:00 UTC), we hold a brief,
-non-technical meeting to decide whether to keep the current area of
-discussion or to adopt a new one. Prior to this meeting, we update the
-"area of discussion" document with summaries of the threads. The
-meeting takes place on [Zulip] and all are welcome to attend.

-A more complete description of our process can be found in [the `process.md` file][p].
+We follow the [Rust's Code of Conduct]. Any concerns should be addressed to the
+[moderation team] immediately.
