In addition to the visual strikingness of using all-caps, UNIX systems +would sort capitals before lower case letters, conveniently putting the README +before the rest of the directory's content[2](#footnote-2). + +The intent is clear: *"This is important information for the user to read before +proceeding."* Let's explore together what constitutes "important information" in +this modern age. + + +## For creators, for consumers + +This is an article about READMEs. About what they do, why they are an absolute +necessity, and how to craft them well. + +This is written for module creators, for as a builder of modules, your job is to +create something that will last. This is an inherent motivation, even if the +author has no intent of sharing their work. Once 6 months pass, a module without +documentation begins to look new and unfamiliar. + +This is also written for module consumers, for every module author is also a +module consumer. Node has a very healthy degree of interdependency: no one lives +at the bottom of the dependency tree. + +Despite being focused on Node, the author contends that its lessons apply +equally well to other programming ecosystems, as well. + + +## Many modules: some good, some bad + +The Node ecosystem is powered by its modules. [npm](https://npmjs.org) is the +magic that makes it all *go*. In the course of a week, Node developers evaluate +dozens of modules for inclusion in their projects. This is a great deal of power +being churned out on a daily basis, ripe for the plucking, just as fast as one +can write `npm install`. + +Like any ecosystem that is extremely accessible, the quality bar varies. npm +does its best to nicely pack away all of these modules and ship them far and +wide. However, the tools found are widely varied: some are shining and new, +others broken and rusty, and still others are somewhere in between. There are +even some that we don't know what they do! + +For modules, this can take the form of inaccurate or unhelpful names (any +guesses what the `fudge` module does?), no documentation, no tests, no source +code comments, or incomprehensible function names. + +Many don't have an active maintainer. If a module has no human available to +answer questions and explain what a module does, combined with no remnants of +documentation left behind, a module becomes a bizarre alien artifact, unusable +and incomprehensible by the archaeologist-hackers of tomorrow. + +For those modules that do have documentation, where do they fall on the quality +spectrum? Maybe it's just a one-liner description: `"sorts numbers by their hex +value"`. Maybe it's a snippet of example code. These are both improvements upon +nothing, but they tend to result in the worst-case scenario for a modern day +module spelunker: digging into the source code to try and understand how it +actually works. Writing excellent documentation is all about keeping the users +*out* of the source code by providing instructions sufficient to enjoy the +wonderful abstractions that your module brings. + +Node has a "wide" ecosystem: it's largely made up of a very long list of +independent do-one-thing-well modules flying no flags but their own. There are +[exceptions](https://github.com/lodash/lodash), but despite these minor fiefdoms, +it is the single-purpose commoners who, given their larger numbers, truly rule the +Node kingdom. + +This situation has a natural consequence: it can be hard to find *quality* modules +that do exactly what you want. + +**This is okay**. Truly. A low bar to entry and a discoverability problem is +infinitely better than a culture problem, where only the privileged few may +participate. + +Plus, discoverability -- as it turns out -- is easier to address. + + +## All roads lead to README.md + +The Node community has responded to the challenge of discoverability in +different ways. + +Some experienced Node developers band together to create [curated +lists](https://github.com/sindresorhus/awesome-nodejs) of quality modules. +Developers leverage their many years examining hundreds of different modules to +share with newcomers the *crème de la crème*: the best modules in each category. +This might also take the form of RSS feeds and mailing lists of new modules deemed +to be useful by trusted community members. + +How about the social graph? This idea spurred the creation of +[node-modules.com](http://node-modules.com/), a npm search replacement that +leverages your GitHub social graph to find modules your friends like or have +made. + +Of course there is also npm's built-in [search](https://npmjs.org) +functionality: a safe default, and the usual port of entry for new developers. + +No matter your approach, regardless whether a module spelunker enters the module +underground at [npmjs.org](https://npmjs.org), +[github.com](https://github.com), or somewhere else, this would-be user will +eventually end up staring your README square in the face. Since your users +will inevitably find themselves here, what can be done to make their first +impressions maximally effective? + + +## Professional module spelunking + +### The README: Your one-stop shop + +A README is a module consumer's first -- and maybe only -- look into your +creation. The consumer wants a module to fulfill their need, so you must explain +exactly what need your module fills, and how effectively it does so. + +Your job is to + +1. tell them what it is (with context) +2. show them what it looks like in action +3. show them how they use it +4. tell them any other relevant details + +This is *your* job. It's up to the module creator to prove that their work is a +shining gem in the sea of slipshod modules. Since so many developers' eyes will +find their way to your README before anything else, quality here is your +public-facing measure of your work. + + +### Brevity + +The lack of a README is a powerful red flag, but even a lengthy README is not +indicative of there being high quality. The ideal README is as short as it can +be without being any shorter. Detailed documentation is good -- make separate +pages for it! -- but keep your README succinct. + + +### Learn from the past + +It is said that those who do not study their history are doomed to make its +mistakes again. Developers have been writing documentation for quite some number +of years. It would be wasteful to not look back a little bit and see what people +did right before Node. + +Perl, for all of the flak it receives, is in some ways the spiritual grandparent +of Node. Both are high-level scripting languages, adopt many UNIX idioms, fuel +much of the internet, and both feature a wide module ecosystem. + +It so turns out that the [monks](http://perlmonks.org) of the Perl community +indeed have a great deal of experience in writing [quality +READMEs](http://search.cpan.org/~kane/Archive-Tar/lib/Archive/Tar.pm). CPAN is a +wonderful resource that is worth reading through to learn more about a community +that wrote consistently high-calibre documentation. + + +### No README? No abstraction + +No README means developers will need to delve into your code in order to +understand it. + +The Perl monks have wisdom to share on the matter: + +> Your documentation is complete when someone can use your module without ever +> having to look at its code. This is very important. This makes it possible for +> you to separate your module's documented interface from its internal +> implementation (guts). This is good because it means that you are free to +> change the module's internals as long as the interface remains the same. +> +> Remember: the documentation, not the code, defines what a module does. +-- [Ken Williams](http://mathforum.org/ken/perl_modules.html#document) + + +### Key elements + +Once a README is located, the brave module spelunker must scan it to discern if +it matches the developer's needs. This becomes essentially a series of pattern +matching problems for their brain to solve, where each step takes them deeper +into the module and its details. + +Let's say, for example, my search for a 2D collision detection module leads me +to [`collide-2d-aabb-aabb`](https://github.com/hackergrrl/collide-2d-aabb-aabb). I +begin to examine it from top to bottom: + +1. *Name* -- self-explanatory names are best. `collide-2d-aabb-aabb` sounds + promising, though it assumes I know what an "aabb" is. If the name sounds too + vague or unrelated, it may be a signal to move on. + +2. *One-liner* -- having a one-liner that describes the module is useful for + getting an idea of what the module does in slightly greater detail. + `collide-2d-aabb-aabb` says it + + > Determines whether a moving axis-aligned bounding box (AABB) collides with + > other AABBs. + + Awesome: it defines what an AABB is, and what the module does. Now to gauge how + well it'd fit into my code: + +3. *Usage* -- rather than starting to delve into the API docs, it'd be great to + see what the module looks like in action. I can quickly determine whether the + example JS fits the desired style and problem. People have lots of opinions + on things like promises/callbacks and ES6. If it does fit the bill, then I + can proceed to greater detail. + +4. *API* -- the name, description, and usage of this module all sound appealing + to me. I'm very likely to use this module at this point. I just need to scan + the API to make sure it does exactly what I need and that it will integrate + easily into my codebase. The API section ought to detail the module's objects + and functions, their signatures, return types, callbacks, and events in + detail. Types should be included where they aren't obvious. Caveats should be + made clear. + +5. *Installation* -- if I've read this far down, then I'm sold on trying out the + module. If there are nonstandard installation notes, here's where they'd go, + but even if it's just a regular `npm install`, I'd like to see that mentioned, + too. New users start using Node all the time, so having a link to npmjs.org + and an install command provides them the resources to figure out how Node + modules work. + +6. *License* -- most modules put this at the very bottom, but this might + actually be better to have higher up; you're likely to exclude a module VERY + quickly if it has a license incompatible with your work. I generally stick to + the MIT/BSD/X11/ISC flavours. If you have a non-permissive license, stick it + at the very top of the module to prevent any confusion. + + +## Cognitive funneling + +The ordering of the above was not chosen at random. + +Module consumers use many modules, and need to look at many modules. + +Once you've looked at hundreds of modules, you begin to notice that the mind +benefits from predictable patterns. + +You also start to build out your own personal heuristic for what information you +want, and what red flags disqualify modules quickly. + +Thus, it follows that in a README it is desirable to have: + +1. a predictable format +2. certain key elements present + +You don't need to use *this* format, but try to be consistent to save your users +precious cognitive cycles. + +The ordering presented here is lovingly referred to as "cognitive funneling," +and can be imagined as a funnel held upright, where the widest end contains the +broadest more pertinent details, and moving deeper down into the funnel presents +more specific details that are pertinent for only a reader who is interested +enough in your work to have reached that deeply in the document. Finally, the +bottom can be reserved for details only for those intrigued by the deeper +context of the work (background, credits, biblio, etc.). + +Once again, the Perl monks have wisdom to share on the subject: + +> The level of detail in Perl module documentation generally goes from +> less detailed to more detailed. Your SYNOPSIS section should +> contain a minimal example of use (perhaps as little as one line of +> code; skip the unusual use cases or anything not needed by most +> users); the DESCRIPTION should describe your module in broad terms, +> generally in just a few paragraphs; more detail of the module's +> routines or methods, lengthy code examples, or other in-depth +> material should be given in subsequent sections. +> +> Ideally, someone who's slightly familiar with your module should be +> able to refresh their memory without hitting "page down". As your +> reader continues through the document, they should receive a +> progressively greater amount of knowledge. +> -- from `perlmodstyle` + + +## Care about people's time + +Awesome; the ordering of these key elements should be decided by how quickly +they let someone 'short circuit' and bail on your module. + +This sounds bleak, doesn't it? But think about it: your job, when you're doing +it with optimal altruism in mind, isn't to "sell" people on your work. It's to +let them evaluate what your creation does as objectively as possible, and decide +whether it meets their needs or not -- not to, say, maximize your downloads or +userbase. + +This mindset doesn't appeal to everyone; it requires checking your ego at the +door and letting the work speak for itself as much as possible. Your only job is +to describe its promise as succinctly as you can, so module spelunkers can +either use your work when it's a fit, or move on to something else that does. + + +## Call to arms! + +Go forth, brave module spelunker, and make your work discoverable and usable +through excellent documentation! + + +## Bonus: other good practices + +Outside of the key points of the article, there are other practices you can +follow (or not follow) to raise your README's quality bar even further and +maximize its usefulness to others: + +1. Consider including a **Background** section if your module depends on + important but not widely known abstractions or other ecosystems. The function + of [`bisecting-between`](https://github.com/hackergrrl/bisecting-between) is not + immediately obvious from its name, so it has a detailed *Background* section + to define and link to the big concepts and abstractions one needs to + understand to use and grok it. This is also a great place to explain the + module's motivation if similar modules already exist on npm. + +2. Aggressively linkify! If you talk about other modules, ideas, or people, make + that reference text a link so that visitors can more easily grok your module + and the ideas it builds on. Few modules exist in a vacuum: all work comes + from other work, so it pays to help users follow your module's history and + inspiration. + +3. Include information on types of arguments and return parameters if it's not + obvious. Prefer convention wherever possible (`cb` probably means callback + function, `num` probably means a `Number`, etc.). + +4. Include the example code in **Usage** as a file in your repo -- maybe as + `example.js`. It's great to have README code that users can actually run if + they clone the repository. + +5. Be judicious in your use of badges. They're easy to + [abuse](https://github.com/angular/angular). They can also be a breeding + ground for bikeshedding and endless debate. They add visual noise to your + README and generally only function if the user is reading your Markdown in a + browser online, since the images are often hosted elsewhere on the + internet. For each badge, consider: "what real value is this badge providing + to the typical viewer of this README?" Do you have a CI badge to show build/test + status? This signal would better reach important parties by emailing + maintainers or automatically creating an issue. Always consider the + audience of the data in your README and ask yourself if there's a flow for + that data that can better reach its intended audience. + +6. API formatting is highly bikesheddable. Use whatever format you think is + clearest, but make sure your format expresses important subtleties: + + a. which parameters are optional, and their defaults + + b. type information, where it is not obvious from convention + + c. for `opts` object parameters, all keys and values that are accepted + + d. don't shy away from providing a tiny example of an API function's use if + it is not obvious or fully covered in the **Usage** section. + However, this can also be a strong signal that the function is too complex + and needs to be refactored, broken into smaller functions, or removed + altogether + + e. aggressively linkify specialized terminology! In markdown you can keep + [footnotes](https://daringfireball.net/projects/markdown/syntax#link) at + the bottom of your document, so referring to them several times throughout + becomes cheap. Some of my personal preferences on API formatting can be + found + [here](https://github.com/hackergrrl/common-readme/blob/master/api_formatting.md) + +7. If your module is a small collection of stateless functions, having a + **Usage** section as a [Node REPL + session](https://github.com/hackergrrl/bisecting-between#example) of function + calls and results might communicate usage more clearly than a source code + file to run. + +8. If your module provides a CLI (command line interface) instead of (or in + addition to) a programmatic API, show usage examples as command invocations + and their output. If you create or modify a file, `cat` it to demonstrate + the change before and after. + +9. Don't forget to use `package.json` + [keywords](https://docs.npmjs.com/files/package.json#keywords) to direct + module spelunkers to your doorstep. + +10. The more you change your API, the more work you need to exert updating + documentation -- the implication here is that you should keep your APIs + small and concretely defined early on. Requirements change over time, but + instead of front-loading assumptions into the APIs of your modules, load + them up one level of abstraction: the module set itself. If the requirements + *do* change and 'do-one-concrete-thing' no longer makes sense, then simply + write a new module that does the thing you need. The 'do-one-concrete-thing' + module remains a valid and valuable model for the npm ecosystem, and your + course correction cost you nothing but a simple substitution of one module for + another. + +11. Finally, please remember that your version control repository and its + embedded README will outlive your [repository host](https://github.com) and + any of the things you hyperlink to -- especially images -- so *inline* anything + that is essential to future users grokking your work. + + +## Bonus: *common-readme* + +Not coincidentally, this is also the format used by +[**common-readme**](https://github.com/hackergrrl/common-readme), a set of README +guidelines and handy command-line generator. If you like what's written here, +you may save some time writing READMEs with `common-readme`. You'll find +real module examples with this format, too. + +You may also enjoy +[standard-readme](https://github.com/richardlitt/standard-readme), which is a +more structured, lintable take on a common README format. + + +## Bonus: Exemplars + +Theory is well and good, but what do excellent READMEs look like?

It contains information that is commonly required to understand what the project is about. + +### Why should I make it? + +It's an easy way to answer questions that your audience will likely have regarding how to install and use your project and also how to collaborate with you. + +### Who should make it? + +Anyone who is working on a programming project, especially if you want others to use it or contribute. + +### When should I make it? + +Definitely before you show a project to other people or make it public. You might want to get into the habit of making it the first file you create in a new project. + +### Where should I put it? + +In the top level directory of the project. This is where someone who is new to your project will start out. Code hosting services such as GitHub, Bitbucket, and GitLab will also look for your README and display it along with the list of files and directories in your project. + +### How should I make it? + +While READMEs can be written in any text file format, the most common one that is used nowadays is Markdown. It allows you to add some lightweight formatting. You can learn more about it at the [CommonMark website](https://commonmark.org/). + +## Suggestions for a Good README + +Every project is different, so consider which of these sections apply to yours. Also keep in mind that while a README can be too long and detailed, **too long is better than too short**. If you think your README is too long, consider utilizing another form of documentation rather than cutting out information. + +### Name + +Choose a self-explaining name for your project. + +### Description + +Let people know what your project can do specifically. Provide context and add a link to any reference visitors might be unfamiliar with. A list of **Features** or a **Background** subsection can also be added here. If there are alternatives to your project, this is a good place to list differentiating factors. + +### Badges + +On some READMEs, you may see small images that convey metadata, such as whether or not all the tests are passing for the project. You can use [Shields.io](http://shields.io/) to add some to your README. Many services also have instructions for adding a badge. + +### Visuals + +Depending on what you are making, it can be a good idea to include screenshots or even a video (you'll frequently see GIFs rather than actual videos). Tools like [ttygif](https://github.com/icholy/ttygif) can help, but check out [Asciinema](https://asciinema.org/) for a more sophisticated method. + +### Installation + +Within a particular ecosystem, there may be a common way of installing things, such as using Yarn, NuGet, or Homebrew. However, consider the possibility that whoever is reading your README is a novice and would like more guidance. Listing specific steps helps remove ambiguity and gets people to using your project as quickly as possible. If it only runs in a specific context like a particular programming language version or operating system or has dependencies that have to be installed manually, also add a **Requirements** subsection. + +### Usage + +Use examples liberally, and show the expected output if you can. It's helpful to have inline the smallest example of usage that you can demonstrate, while providing links to more sophisticated examples if they are too long to reasonably include in the README. + +### Support + +Tell people where they can go to for help. It can be any combination of an issue tracker, a chat room, an email address, etc. + +### Roadmap + +If you have ideas for releases in the future, it is a good idea to list them in the README. + +### Contributing + +State if you are open to contributions and what your requirements are for accepting them. + +For people who want to make changes to your project, it's helpful to have some documentation on how to get started. Perhaps there is a script that they should run or some environment variables that they need to set. Make these steps explicit. These instructions could also be useful to your future self. + +You can also document commands to lint the code or run tests. These steps help to ensure high code quality and reduce the likelihood that the changes inadvertently break something. Having instructions for running tests is especially helpful if it requires external setup, such as starting a Selenium server for testing in a browser. + +### Authors and Acknowledgment + +Show your appreciation to those who have contributed to the project. + +### License + +For open source projects, say how it is licensed. + +### Project Status + +If you have run out of energy or time for your project, put a note at the top of the README saying that development has slowed down or stopped completely. Someone may choose to fork your project or volunteer to step in as a maintainer or owner, allowing your project to keep going. You can also make an explicit request for maintainers. + +## FAQ + +### Is there a standard README format? + +Not all of the suggestions here will make sense for every project, so it's really up to the developers what information should be included in the README. + +### What should the README file be named? + +`README.md` (or a different file extension if you choose to use a non-Markdown file format). It is traditionally uppercase so that it is more prominent, but it's not a big deal if you think it looks better lowercase. + +## What's Next? + +### More Documentation + +A README is a crucial but basic way of documenting your project. While every project should at least have a README, more involved ones can also benefit from a wiki or a dedicated documentation website. Tools include: + +- [Docusaurus](https://docusaurus.io/) +- [GitBook](https://www.gitbook.com/) +- [MkDocs](https://www.mkdocs.org/) +- [Read the Docs](https://readthedocs.org/) +- [Docsify](https://docsify.js.org/) + +### Changelog + +A [changelog](https://en.wikipedia.org/wiki/Changelog) is another file that is very useful for programming projects. See [Keep a Changelog](http://keepachangelog.com/). + +### Contributing Guidelines + +Just having a "Contributing" section in your README is a good start. Another approach is to split off your guidelines into their own file (`CONTRIBUTING.md`). If you use GitHub and have this file, then anyone who creates an issue or opens a pull request will get a link to it. + +You can also create an issue template and a pull request template. These files give your users and collaborators templates to fill in with the information that you'll need to properly respond. diff --git a/.agents/skills/crafting-effective-readmes/references/standard-readme-example-maximal.md b/.agents/skills/crafting-effective-readmes/references/standard-readme-example-maximal.md new file mode 100644 index 0000000..4ccdf57 --- /dev/null +++ b/.agents/skills/crafting-effective-readmes/references/standard-readme-example-maximal.md @@ -0,0 +1,68 @@ +# Title + +![banner](assets/text_wordmark_dark.png) + +![GitHub Created At](https://img.shields.io/github/created-at/RichardLitt/standard-readme?color=bright-green&style=flat-square) +![GitHub contributors](https://img.shields.io/github/contributors/RichardLitt/standard-readme?color=bright-green&style=flat-square) +[![license](https://img.shields.io/github/license/RichardLitt/standard-readme.svg?color=bright-green&style=flat-square)](LICENSE) +[![standard-readme compliant](https://img.shields.io/badge/readme%20style-standard-brightgreen.svg?style=flat-square)](https://github.com/RichardLitt/standard-readme) + +This is an example file with maximal choices selected. + +This is a long description. + +## Table of Contents + +- [Security](#security) +- [Background](#background) +- [Install](#install) +- [Usage](#usage) +- [API](#api) +- [Contributing](#contributing) +- [License](#license) + +## Security + +### Any optional sections + +## Background + +### Any optional sections + +## Install + +This module depends upon a knowledge of [Markdown](). + +``` +``` + +### Any optional sections + +## Usage + +``` +``` + +Note: The `license` badge image link at the top of this file should be updated with the correct `:user` and `:repo`. + +### Any optional sections + +## API + +### Any optional sections + +## More optional sections + +## Contributing + +See [the contributing file](CONTRIBUTING.md)! + +PRs accepted. + +Small note: If editing the Readme, please conform to the [standard-readme](https://github.com/RichardLitt/standard-readme) specification. + +### Any optional sections + +## License + +[MIT © Richard McRichface.](../LICENSE) diff --git a/.agents/skills/crafting-effective-readmes/references/standard-readme-example-minimal.md b/.agents/skills/crafting-effective-readmes/references/standard-readme-example-minimal.md new file mode 100644 index 0000000..13d94b7 --- /dev/null +++ b/.agents/skills/crafting-effective-readmes/references/standard-readme-example-minimal.md @@ -0,0 +1,21 @@ +# Title + +This is an example file with default selections. + +## Install + +``` +``` + +## Usage + +``` +``` + +## Contributing + +PRs accepted. + +## License + +MIT © Richard McRichface diff --git a/.agents/skills/crafting-effective-readmes/references/standard-readme-spec.md b/.agents/skills/crafting-effective-readmes/references/standard-readme-spec.md new file mode 100644 index 0000000..91a4961 --- /dev/null +++ b/.agents/skills/crafting-effective-readmes/references/standard-readme-spec.md @@ -0,0 +1,242 @@ +# Standard README Specification + +> Source: [Standard Readme](https://github.com/RichardLitt/standard-readme) by Richard Litt + +A compliant README must satisfy all the requirements listed below. + +> Note: Standard Readme is designed for open source libraries.
