+Overview
+--------
 
-General
--------
-The LNP/BP projects operate an open contributor model where anyone is welcome to 
-contribute towards development in the form of peer review, documentation, 
-testing and patches.
-
-Anyone is invited to contribute without regard to technical experience, 
-"expertise", OSS experience, age, or other concern. However, the development of 
-standards & reference implementations demands a high-level of rigor, adversarial 
-thinking, thorough testing and risk-minimization. Any bug may cost users real 
-money. That being said, we deeply welcome people contributing for the first time 
-to an open source project or pick up Rust while contributing. Don't be shy, 
-you'll learn.
-
-Communications Channels
------------------------
-Communication about LNP/BP standards & implementations happens primarily 
-on #lnp-pb IRC chat on Freenode with the logs available at 
-<http://gnusha.org/lnp-bp/>
-
-Discussion about code base improvements happens in GitHub issues and on pull
-requests.
-
-Major projects are tracked [here](https://github.com/orgs/LNP-BP/projects).
-Project roadmap is tracked in each repository GitHub milestones.
+* Before adding any code dependencies, check with the maintainers if this is okay.
+* Write properly formatted comments: they should be English sentences, eg:
 
-Asking Questions

-Alternatively, we have a dedicated developer channel on IRC, #[email protected]
-where you may get helpful advice if you have questions.
+* Read the DCO and make sure all commits are signed off, using `git commit -s`.
+* Follow the guidelines when proposing code changes (see below).
+* Write properly formatted git commits (see below).
+* Run the tests with `cargo test --workspace --all-features`.

+### Proposing changes
+
+When proposing changes via a pull-request or patch:
+
+* Isolate changes in separate commits to make the review process easier.
+* Don't make unrelated changes, unless it happens to be an obvious improvement to
+  code you are touching anyway ("boyscout rule").
+* Rebase on `master` when needed.
+* Keep your changesets small, specific and uncontroversial, so that they can be
+  merged more quickly.
+* If the change is substantial or requires re-architecting certain parts of the
+  codebase, write a proposal in English first, and get consensus on that before
+  proposing the code changes.

+### Writing Git commit messages
+
+A properly formed git commit subject line should always be able to complete the
+following sentence:
+
+     If applied, this commit will _____
+
+In addition, it should be capitalized and *must not* include a period.
+
+For example, the following message is well formed:
+
+     Add support for .gif files
+
+While these ones are **not**: `Adding support for .gif files`,
+`Added support for .gif files`.
+
+When it comes to formatting, here's a model git commit message[1]:
+
+     Capitalized, short (50 chars or less) summary
+
+     More detailed explanatory text, if necessary.  Wrap it to about 72
+     characters or so.  In some contexts, the first line is treated as the
+     subject of an email and the rest of the text as the body.  The blank
+     line separating the summary from the body is critical (unless you omit
+     the body entirely); tools like rebase can get confused if you run the
+     two together.
+
+     Write your commit message in the imperative: "Fix bug" and not "Fixed bug"
+     or "Fixes bug."  This convention matches up with commit messages generated
+     by commands like git merge and git revert.
+
+     Further paragraphs come after blank lines.
+
+     - Bullet points are okay, too.
+
+     - Typically a hyphen or asterisk is used for the bullet, followed by a
+       single space, with blank lines in between, but conventions vary here.
+
+     - Use a hanging indent.
+
 ### Peer review
 
 Anyone may participate in peer review which is expressed by comments in the pull
 request. Typically reviewers will review the code for obvious errors, as well as
 test out the patch set and opine on the technical merits of the patch. PR should

-Testing
--------
-Related to the security aspect, LNP/BP developers take testing very seriously.

-Fuzzing is heavily encouraged: feel free to add related material under `fuzz/`

-Mutation testing is planned; any contribution there would be warmly welcomed.
