+# like "1.0.0", "v0.1.0-prerelease.1", "my-app/0.1.0", "releases/v1.0.0", etc.
+# Various formats will be parsed into a VERSION and an optional PACKAGE_NAME, where
+# PACKAGE_NAME must be the name of a Cargo package in your workspace, and VERSION
+# must be a Cargo-style SemVer Version (must have at least major.minor.patch).
+#
+# If PACKAGE_NAME is specified, then the announcement will be for that
+# package (erroring out if it doesn't have the given version or isn't cargo-dist-able).
+#
+# If PACKAGE_NAME isn't specified, then the announcement will be for all
+# (cargo-dist-able) packages in the workspace with that version (this mode is
+# intended for workspaces with only one dist-able package, or with all dist-able
+# packages versioned/released in lockstep).
+#
+# If you push multiple tags at once, separate instances of this workflow will
+# spin up, creating an independent announcement for each one. However Github
+# will hard limit this to 3 tags per commit, as it will assume more tags is a
+# mistake.
+#
+# If there's a prerelease-style suffix to the version, then the release(s)

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socioeconomic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+sylvestre@debian.org.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+

+# Contributing to findutils
+
+Hi! Welcome to uutils/findutils!
+
+Thanks for wanting to contribute to this project! This document explains
+everything you need to know to contribute. Before you start make sure to also
+check out these documents:
+
+- Our community's [CODE_OF_CONDUCT.md](./CODE_OF_CONDUCT.md).
+- [DEVELOPMENT.md](./DEVELOPMENT.md) for setting up your development
+  environment.
+
+Now follows a very important warning:
+
+> [!WARNING]
+> uutils is original code and cannot contain any code from GNU or
+> other implementations. This means that **we cannot accept any changes based on
+> the GNU source code**. To make sure that cannot happen, **you cannot link to
+> the GNU source code** either. It is however possible to look at other implementations
+> under a BSD or MIT license like [Apple's implementation](https://opensource.apple.com/source/file_cmds/)
+> or [OpenBSD](https://github.com/openbsd/src/tree/master/bin).
+
+Finally, feel free to join our [Discord](https://discord.gg/wQVJbvJ)!
+
+<!-- TODO: Getting Oriented -->
+
+## Design Goals
+
+We have the following goals with our development:
+
+- **Compatible**: The utilities should be a drop-in replacement for the GNU
+  coreutils.
+- **Cross-platform**: All utilities should run on as many of the supported
+  platforms as possible.
+- **Reliable**: The utilities should never unexpectedly fail.
+- **Performant**: Our utilities should be written in fast idiomatic Rust. We aim
+  to match or exceed the performance of the GNU utilities.
+- **Well-tested**: We should have a lot of tests to be able to guarantee
+  reliability and compatibility.
+
+## How to Help
+
+There are several ways to help and writing code is just one of them. Reporting
+issues and writing documentation are just as important as writing code.
+
+### Reporting Issues
+
+We can't fix bugs we don't know about, so good issues are super helpful! Here
+are some tips for writing good issues:
+
+- If you find a bug, make sure it's still a problem on the `main` branch.
+- Search through the existing issues to see whether it has already been
+  reported.
+- Make sure to include all relevant information, such as:
+  - Which version of uutils did you check?
+  - Which version of GNU coreutils are you comparing with?
+  - What platform are you on?
+- Provide a way to reliably reproduce the issue.
+- Be as specific as possible!
+
+### Writing Documentation
+
+There's never enough documentation. If you come across any documentation that
+could be improved, feel free to submit a PR for it!
+
+### Writing Code
+
+If you want to submit a PR, make sure that you've discussed the solution with
+the maintainers beforehand. We want to avoid situations where you put a lot of
+work into a fix that we can't merge! If there's no issue for what you're trying
+to fix yet, make one _before_ you start working on the PR.
+
+Generally, we try to follow what GNU is doing in terms of options and behavior.
+It is recommended to look at the GNU findtils manual
+([on the web](https://www.gnu.org/software/findutils/manual/html_node/index.html),
+or locally using `info <utility>`). It is more in depth than the man pages and
+provides a good description of available features and their implementation
+details. But remember, you cannot look at the GNU source code!
+
+Also remember that we can only merge PRs which pass our test suite, follow
+rustfmt, and do not have any warnings from clippy. See
+[DEVELOPMENT.md](./DEVELOPMENT.md) for more information. Be sure to also read
+about our [Rust style](#our-rust-style).
+
+## Our Rust Style
+
+We want uutils to be written in idiomatic Rust, so here are some guidelines to
+follow. Some of these are aspirational, meaning that we don't do them correctly
+everywhere in the code. If you find violations of the advice below, feel free to
+submit a patch!
+
+### Don't `panic!`
+
+The coreutils should be very reliable. This means that we should never `panic!`.
+Therefore, you should avoid using `.unwrap()` and `panic!`. Sometimes the use of
+`unreachable!` can be justified with a comment explaining why that code is
+unreachable.
+
+### Don't `exit`
+
+We want uutils to be embeddable in other programs. This means that no function
+in uutils should exit the program. Doing so would also lead to code with more
+confusing control flow. Avoid therefore `std::process::exit` and similar
+functions which exit the program early.
+
+### `unsafe`
+
+uutils cannot be entirely safe, because we have to call out to `libc` and do
+syscalls. However, we still want to limit our use of `unsafe`. We generally only
+accept `unsafe` for FFI, with very few exceptions. Note that performance is very
+rarely a valid argument for using `unsafe`.
+
+If you still need to write code with `unsafe`, make sure to read the
+[Rustonomicon](https://doc.rust-lang.org/nomicon/intro.html) and annotate the
+calls with `// SAFETY:` comments explaining why the use of `unsafe` is sound.
+
+### Macros
+
+Macros can be a great tool, but they are also usually hard to understand. They
+should be used sparingly. Make sure to explore simpler options before you reach
+for a solution involving macros.
+
+### `str`, `OsStr` & `Path`
+
+Rust has many string-like types, and sometimes it's hard to choose the right
+one. It's tempting to use `str` (and `String`) for everything, but that is not
+always the right choice for uutils, because we need to support invalid UTF-8,
+just like the GNU coreutils. For example, paths on Linux might not be valid
+UTF-8! Whenever we are dealing with paths, we should therefore stick with
+`OsStr` and `Path`. Make sure that you only convert to `str`/`String` if you
+know that something is always valid UTF-8. If you need more operations on
+`OsStr`, you can use the [`bstr`](https://docs.rs/bstr/latest/bstr/) crate.
+
+### Doc-comments
+
+We use rustdoc for our documentation, so it's best to follow
+[rustdoc's guidelines](https://doc.rust-lang.org/rustdoc/how-to-write-documentation.html#documenting-components).
+Make sure that your documentation is not just repeating the name of the
+function, but actually giving more useful information. Rustdoc recommends the
+following structure:
+
+```
+[short sentence explaining what it is]
+
+[more detailed explanation]
+
+[at least one code example that users can copy/paste to try it]
+
+[even more advanced explanations if necessary]
+```
+
+### Other comments
+
+Comments should be written to _explain_ the code, not to _describe_ the code.
+Try to focus on explaining _why_ the code is the way it is. If you feel like you
+have to describe the code, that's usually a sign that you could improve the
+naming of variables and functions.
+
+If you edit a piece of code, make sure to update any comments that need to
+change as a result. The only thing worse than having no comments is having
+outdated comments!
+
+## Git Etiquette
+
+To ensure easy collaboration, we have guidelines for using Git and GitHub.
+
+### Commits
+
+- Make small and atomic commits.
+- Keep a clean history of commits.
+- Write informative commit messages.
+- Annotate your commit message with the component you're editing. For example:
+  `cp: do not overwrite on with -i` or `uucore: add support for FreeBSD`.
+- Do not unnecessarily move items around in the code. This makes the changes
+  much harder to review. If you do need to move things around, do that in a
+  separate commit.
+
+### Commit messages
+
+You can read this section in the Git book to learn how to write good commit
+messages: https://git-scm.com/book/ch5-2.html.
+
+In addition, here are a few examples for a summary line when committing to
+uutils:
+
+- commit for a single utility
+
+```
+nohup: cleanup and refactor
+```
+
+- commit for a utility's tests
+
+```
+tests/rm: test new feature
+```
+
+Beyond changes to an individual utility or its tests, other summary lines for
+non-utility modules include:
+
+```
+README: add help
+uucore: add new modules
+uutils: add new utility
+gitignore: add temporary files
+```
+
+### PRs
+
+- Make the titles of PRs descriptive.
+  - This means describing the problem you solve. For example, do not write
+    `Fix #1234`, but `ls: fix version sort order`.
+  - You can prefix the title with the utility the PR concerns.
+- Keep PRs small and self-contained. A set of small PRs is much more likely to
+  get merged quickly than one large PR.
+- Make sure the CI passes (up to intermittently failing tests).
+- You know your code best, that's why it's best if you can solve merge conflicts
+  on your branch yourself.
+  - It's up to you whether you want to use `git merge main` or
+    `git rebase main`.
+  - Feel free to ask for help with merge conflicts.
+- You do not need to ping maintainers to request a review, but it's fine to do
+  so if you don't get a response within a few days.
+
+## Platforms
+
+We take pride in supporting many operating systems and architectures. Any code
+you contribute must at least compile without warnings for all platforms in the
+CI. However, you can use `#[cfg(...)]` attributes to create platform dependent
+features.
+
+**Tip:** For Windows, Microsoft provides some images (VMWare, Hyper-V,
+VirtualBox and Parallels) for development:
+<https://developer.microsoft.com/windows/downloads/virtual-machines/>
+
+## Licensing
+
+uutils is distributed under the terms of the MIT License; see the `LICENSE` file
+for details. This is a permissive license, which allows the software to be used
+with few restrictions.
+
+Copyrights in the uutils project are retained by their contributors, and no
+copyright assignment is required to contribute.
+
+If you wish to add or change dependencies as part of a contribution to the
+project, a tool like `cargo-license` can be used to show their license details.
+The following types of license are acceptable:
+
+- MIT License
+- Dual- or tri-license with an MIT License option ("Apache-2.0 or MIT" is a
+  popular combination)
+- "MIT equivalent" license (2-clause BSD, 3-clause BSD, ISC)
+- License less restrictive than the MIT License (CC0 1.0 Universal)
+- Apache License version 2.0
+
+Licenses we will not use:
+
+- An ambiguous license, or no license
+- Strongly reciprocal licenses (GNU GPL, GNU LGPL)
+
+If you wish to add a reference but it doesn't meet these requirements, please
+raise an issue to describe the dependency.

+
+## Before you start
+
+For this guide we assume that you already have a GitHub account and have `git` and your favorite code editor or IDE installed and configured.
+Before you start working on findutils, please follow these steps:
+
+1. Fork the [findutils repository](https://github.com/uutils/findutils) to your GitHub account.
+***Tip:*** See [this GitHub guide](https://docs.github.com/en/get-started/quickstart/fork-a-repo) for more information on this step.
+2. Clone that fork to your local development environment:
+
+```shell
+git clone https://github.com/YOUR-GITHUB-ACCOUNT/findutils
+cd findutils
+```
+
+## Tools
+
+You will need the tools mentioned in this section to build and test your code changes locally.
+This section will explain how to install and configure these tools.
+We also have an extensive CI that uses these tools and will check your code before it can be merged.
+The next section [Testing](#testing) will explain how to run those checks locally to avoid waiting for the CI.
+
+### Rust toolchain
+
+[Install Rust](https://www.rust-lang.org/tools/install)
+
+If you're using rustup to install and manage your Rust toolchains, `clippy` and `rustfmt` are usually already installed. If you are using one of the alternative methods, please make sure to install them manually. See following sub-sections for their usage: [clippy](#clippy) [rustfmt](#rustfmt).
+
+***Tip*** You might also need to add 'llvm-tools' component if you are going to [generate code coverage reports locally](#code-coverage-report):
+
+```shell
+rustup component add llvm-tools-preview
+```
+
+### pre-commit hooks
+
+A configuration for `pre-commit` is provided in the repository. It allows
+automatically checking every git commit you make to ensure it compiles, and
+passes `clippy` and `rustfmt` without warnings.
+
+To use the provided hook:
+
+1. [Install `pre-commit`](https://pre-commit.com/#install)
+1. Run `pre-commit install` while in the repository directory
+
+Your git commits will then automatically be checked. If a check fails, an error
+message will explain why, and your commit will be canceled. You can then make
+the suggested changes, and run `git commit ...` again.
+
+**NOTE: On MacOS** the pre-commit hooks are currently broken. There are workarounds involving switching to unstable nightly Rust and components.
+
+### clippy
+
+```shell
+cargo clippy --all-targets --all-features
+```
+
+The `msrv` key in the clippy configuration file `clippy.toml` is used to disable
+lints pertaining to newer features by specifying the minimum supported Rust
+version (MSRV).
+
+### rustfmt
+
+```shell
+cargo fmt --all
+```
+
+### cargo-deny
+
+This project uses [cargo-deny](https://github.com/EmbarkStudios/cargo-deny/) to
+detect duplicate dependencies, checks licenses, etc. To run it locally, first
+install it and then run with:
+
+```shell
+cargo deny --all-features check all
+```
+
+### Markdown linter
+
+We use [markdownlint](https://github.com/DavidAnson/markdownlint) to lint the
+Markdown files in the repository.
+
+### Spell checker
+
+We use `cspell` as spell checker for all files in the project. If you are using
+VS Code, you can install the
+[code spell checker](https://marketplace.visualstudio.com/items?itemName=streetsidesoftware.code-spell-checker)
+extension to enable spell checking within your editor. Otherwise, you can
+install [cspell](https://cspell.org/) separately.
+
+If you want to make the spell checker ignore a word, you can add
+
+```rust
+// spell-checker:ignore word_to_ignore
+```
+
+at the top of the file.
+
+## Testing
+
+Just like with building, we follow the standard procedure for testing using
+Cargo:
+
+```shell
+cargo test
+```
+
+## Code coverage report
+
+Code coverage report can be generated using [grcov](https://github.com/mozilla/grcov).
+
+### Using Nightly Rust
+
+To generate [gcov-based](https://github.com/mozilla/grcov#example-how-to-generate-gcda-files-for-a-rust-project) coverage report
+
+```shell
+export CARGO_INCREMENTAL=0
+export RUSTFLAGS="-Zprofile -Ccodegen-units=1 -Copt-level=0 -Clink-dead-code -Coverflow-checks=off -Zpanic_abort_tests -Cpanic=abort"
+export RUSTDOCFLAGS="-Cpanic=abort"
+cargo build <options...>
+cargo test <options...>
+grcov . -s . --binary-path ./target/debug/ -t html --branch --ignore-not-existing --ignore build.rs --excl-br-line "^\s*((debug_)?assert(_eq|_ne)?\#\[derive\()" -o ./target/debug/coverage/
+# open target/debug/coverage/index.html in browser
+```
+
+if changes are not reflected in the report then run `cargo clean` and run the above commands.
+
+### Using Stable Rust
+
+If you are using stable version of Rust that doesn't enable code coverage instrumentation by default
+then add `-Z-Zinstrument-coverage` flag to `RUSTFLAGS` env variable specified above.
+
+## Tips for setting up on Mac
+
+### C Compiler and linker
+
+On MacOS you'll need to install C compiler & linker:
+
+```shell
+xcode-select --install
+```
+
+## Tips for setting up on Windows
+
+### MSVC build tools
+
+On Windows you'll need the MSVC build tools for Visual Studio 2013 or later.
+
+If you are using `rustup-init.exe` to install Rust toolchain, it will guide you through the process of downloading and installing these prerequisites.
+
+Otherwise please follow [this guide](https://learn.microsoft.com/en-us/windows/dev-environment/rust/setup).
