In fashionable software program improvement, agility isn’t a matter of velocity — it’s about being adaptable, open, and constant. Whereas a lot of the eye in Agile improvement is concentrated round iterations, sprints, and steady supply, documentation typically falls behind.
However what if the documentation might sustain with the code? That’s precisely what Documentation as Code is about.
At its coronary heart, this method treats documentation like software program code: it’s versioned, re-inspected, examined, and deployed utilizing the identical instruments and workflows.
This idea is in precise alignment with the “Single Supply of Fact” philosophy that makes an attempt to carry and solidify data collectively in a mission so it doesn’t create confusion, redundancy, and miscommunication.
Let’s dive into what Documentation as Code (Docs as Code) is and the way it permits this philosophy in Agile settings.
What Is Documentation as Code?
Documentation as Code refers back to the observe of writing and supporting documentation utilizing the identical processes and instruments which are used for writing code.
As an alternative of storing technical content material in exterior programs reminiscent of Phrase paperwork or wikis, Docs as Code shops every thing in a model management system, sometimes Git.
Because of this documentation:
- Lives in the identical repositories because the supply code.
- Is written in light-weight markup languages reminiscent of Markdown or AsciiDoc.
- Follows the identical branching, pull request, and code overview workflows.
- Is built-in into the CI/CD pipeline, the place documentation may be mechanically linted, examined, and deployed.
The important thing ideas of the Documentation as Code philosophy collaborate with each other to maintain documentation exact, up-to-date, and simple to manipulate.
To start with, by utilizing model management, each change to the documentation is tracked and may be rolled again if wanted, similar to with code.
Automation, in flip, helps simplify the method — builds, previews, and error checks occur independently, which suggests much less work concerned and faster supply.
Additional, as a result of the identical software units are used when creating customized software program, collaboration is method simpler. Builders, product managers, and technical writers may even contribute in accordance with established workflows.
The One Supply of Fact Philosophy
One Supply of Fact implies having data in a one single location, which everyone on the staff can consult with.
It’s easy in Agile improvement to have the documentation get unruly — there may be a few of it on wikis, some on shared drives, and a few buried in previous e mail threads.
With Documentation as Code, in flip, the Single Supply of Fact turns into the codebase itself. The documentation exists alongside the code, in the identical model management repository, and makes use of the identical workflow.
Put merely, any alteration to the code may be adopted by the matching documentation replace and everybody mechanically is aware of about it.
By linking code and documentation collectively, groups keep away from duplication, cut back errors, and facilitate communication. This fashion, it’s a lot simpler to belief documentation — as a result of it will get up to date similar to the code, and by the identical folks.
Advantages of Documentation as Code in Agile Software program Improvement
Total, Documentation as Code possesses some compelling advantages in Agile improvement, serving to groups work sooner, wiser, and with fewer misunderstandings.
First, it retains documentation updated. As a result of it’s being saved and saved with the code, any modifications may be carried out and reviewed directly. No ready for an individual to revise a separate doc or wiki down the road.
Second, it improves teamwork. All of the contributors, from builders and testers to writers and product managers, can contribute to the documentation utilizing the identical instruments they use to code.
Third, it impacts the code’s high quality. Writing and validating technical documentation concurrently with code forces builders to pay extra consideration to how their code behaves, which tends to result in a greater design with fewer bugs.
Fourth, builders can add automated checks and assessments to the CI/CD pipeline. They will mechanically discover damaged hyperlinks, misspellings, or out of date references within the docs, the identical method they will discover code.
Lastly, quite a few affluent corporations are already working towards this method. GitLab and Kubernetes initiatives have indicated that placing documentation into the event course of leads to extra secure, useful, and easier-to-use documentation.
Easy methods to Implement Documentation as Code
Getting Documentation as Code reside isn’t that troublesome, however it can take you to change the best way your staff operates. The perfect recommendation right here is to start out small and steadily transfer towards making Docs as Code part of your course of.
1. Begin Small
To begin with, select a small mission or a selected module to doc utilizing Docs as Code. This step permits your staff to get accustomed to the method with out feeling overwhelmed.
Then write documentation for one or two options or elements and retailer it in the identical Git repository as your code. This fashion, you’ll get a really feel for the way documentation may be handled like code.
2. Use the Proper Instruments
Subsequent, double-check you’ve gotten the best instruments at hand. For model management, you’ll need to use a system like Git (with GitHub, GitLab, or Bitbucket).
For writing the documentation itself, you should utilize easy markup languages, reminiscent of Markdown, AsciiDoc, or reStructuredText.
Additional, take into account making use of static website mills like MkDocs, Docusaurus, or Hugo to show your Markdown recordsdata into an expert, user-oriented documentation web site.
Lastly, combine your documentation into your CI/CD pipeline (e.g., GitHub Actions, GitLab CI, or CircleCI) to be able to auto-format checks, spelling checks, and deployment.
3. Incorporate Documentation into Your Workflow
When you’ve gotten the instruments arrange, it’s time to merge documentation into your improvement workflow. Put merely, it means inserting documentation adjustments in the identical pipeline as code adjustments.
If a developer creates code, they have to additionally replace or add the respective documentation in the identical commit. To maintain all of the components organized, it’s essential to create pull requests for documentation adjustments and overview them similar to you’d overview code adjustments.
4. Educate Your Group
Apart from, it’s essential to coach your staff on how Docs as Code works. This implies explaining the instruments you’ll use, the workflows, and the advantages of getting documentation in model management.
Have interaction builders, product managers, and technical writers to play lively roles in including to documentation. Collective duty will make documentation a staff effort, not the only real duty of 1 individual.
5. Keep away from Frequent Pitfalls
On the similar time, watch out to not fall into frequent traps when going Docs as Code. One mistake to keep away from is over-engineering the documentation course of on the onset. As an alternative, simplify issues first after which add more and more extra complicated instruments or processes.
One other mistake is forgetting documentation after the preliminary setup is full. To be able to maintain your docs up-to-date, embrace them within the CI/CD pipeline and encourage common overview. A quick reminder: if you happen to maintain documentation a low precedence, it can simply fall behind.
6. Undertake Steady Enchancment
Lastly, keep in mind that Docs as Code is a steady course of. The extra your staff will get used to the workflow, the extra it is possible for you to to streamline and refine it much more.
You may, for example, add even larger automation, enhance the model, and even add person suggestions to additional improve the documentation. What is important is to deal with it as a long-term funding that pays off within the type of higher collaboration and a greater improvement course of.
Challenges and Concerns of Creating Documentation in Software program Improvement
One of many greatest challenges is to maintain the documentation updated when the code is being edited. To resolve this, there’s a must replace the documentation and likewise the code.
One other drawback is duplication. Programmers prefer to remark within the code how issues are achieved, and sometimes this repeats the documentation.
Whereas code feedback are essential, they have to give attention to technical particulars within the code, and the documentation ought to present clear, high-level data for customers.
Adopting Docs as Code additionally requires remodeling how the staff works, which may be difficult for people used to conventional documentation. Among the staff members may resist at first, however with time, after they see the advantages, it turns into painless.
Although automation helps, it will possibly’t do every thing. Instruments can seek for small errors, however they will’t inform if the documentation is unambiguous or useful. That takes human involvement. Reviewing the documentation frequently ensures that it’s invaluable and correct.
Lastly, as your mission progresses, the system documentation can grow to be outdated or disconnected from the place the product is. To forestall this, it’s essential to have evaluations and updates frequently.
Having an individual who has the duty of maintaining a tally of particular areas of the documentation may maintain every thing correct and true to life.
Problem | Answer |
Holding Documentation As much as Date | Replace code and documentation collectively. |
Duplication of Info | Preserve code feedback technical; documentation ought to give attention to high-level information. |
Adopting Docs as Code | Regularly transition, displaying advantages over time. |
Automation Limitations | Common human evaluations to make sure readability and accuracy. |
Outdated Documentation | Common evaluations and updates to align with the newest product model. |
Lack of Possession | Assign staff members to supervise particular areas of documentation. |
Actual-World Use Circumstances of Leveraging Software program Documentation
To get an thought of how Documentation as Code operates in precise environments, let’s analyze some use circumstances of firms and initiatives which have efficiently enforced this technique.
The circumstances beneath research illustrate how Docs as Code aids in enhancing collaboration, sustaining related documentation, and making the event course of extra sufficient.
1. GitLab: A Chief in Docs as Code
GitLab, a well-known DevOps and CI/CD software, is a superb instance of an organization that has welcomed Documentation as Code.
Its docs are saved in the identical Git repository because the code, and all the staff works collectively to keep up it as much as the minute.
The corporate makes use of GitLab’s personal CI/CD pipeline to mechanically produce and deploy the documentation every time a change is pushed to the codebase.
Because of such an association, all mission members can simply entry and leverage the documentation. And since it’s a part of the event course of, GitLab sidesteps the traditional drawback of documentation rising outdated or forgotten.
It additionally unites all the staff—builders, technical writers, and everybody else can contribute to the documentation in the identical method they contribute to the code.
2. Kubernetes: Open Supply Success
Kubernetes is yet one more nice instance of how Documentation as Code is practiced.
All person documentation and API references for Kubernetes are saved in the identical Git repository as their code. This means that every time the software program is being altered, it’s easy to replace the documentation too.
Additionally they make use of automation to examine for issues like hyperlink breaks or out of date code examples.
Total, because of this course of, a lot of contributors repeatedly refine the code and documentation at common intervals, guaranteeing that each piece of labor is present and reliable.
3. Stripe: Holding Documentation in Sync with Code
Stripe, a longtime cost firm, additionally makes use of Documentation as Code to maintain its API documentation updated.
As their staff adjusts their API, they modify their documentation together with the code throughout the similar Git repository. This fashion, all edits are immediately mirrored within the official docs.
By together with documentation in the identical course of as coding, Stripe avoids the inconvenience of sustaining separate documentation and supplies customers with the newest and finest data always.
The Function of Technical Writers in Docs as Code
Within the technique of Docs as Code, technical writers have an especially essential place. Whereas the builders write down the technical data, technical writers double-check that such data isn’t troublesome to learn, structured adequately, and simple to know for everybody.
Technical writers remodel difficult technical language into components anybody can perceive, and that is particularly vital in Agile initiatives the place each software program and documentation get developed hand-in-hand.
Technical writers additionally work with builders, utilizing the identical Git repository in order that the documentation is all the time updated with the newest code.
Their information makes the documentation correct, well-organized, and useful. They overview updates, gather solutions, and use automation instruments to catch small errors.
Typically, technical writers fill the hole between the technical facet of improvement and the wants of customers, making the entire documentation course of a hit.
