  3. Follow the template provided in the Instructions and Templates directory to craft your tutorial or tutorial proposal.
  4. Submit your work by creating a pull request from your branch to the main branch of this repository.

Documentation testing

We treat documentation like code. Therefore, we use processes similar to those used for code to maintain standards and quality of documentation.

We have tests:

  • To lint the words and structure of the documentation.

Run tests locally

You can run these tests on your local computer. This has the advantage of speeding up the feedback loop. You can know of any problems with the changes in your branch without waiting for a CI pipeline to run.

To run the tests locally, it's important to:

  • Install the tools
  • Run linters the same way they are run in CI pipelines. It's important to use same configuration we use in CI pipelines, which can be different than the default configuration of the tool.

Local linters

To help adhere to the documentation style guidelines, and improve the content added to documentation, install documentation linters and integrate them with your code editor.

At Thoth Tech, we mostly use:

Prettier

Prettier checks that Markdown syntax follows the CommonMark specifications.

Vale

Vale is a grammar, style, and word usage linter for the English language. Vale's configuration is stored in the .vale.ini file located in the root directory.

Vale supports creating custom tests that extend any of several types of checks, which we store in the .vale/thothtech/ directory in the documentation directory.

Vale result types

Vale returns three types of results:

  • Error - For words or phrases with ambiguous meanings.
  • Warning - For writing style preferences.
  • Suggestion - For basic writing tenets and best practices.
Vale readability score

In ReadingLevel.yml, we have implemented the Flesch-Kincaid grade level test to determine the readability of our documentation.

As a general guideline, the lower the score, the more readable the documentation. For example, a page that scores 12 before a set of changes, and 9 after, indicates an iterative improvement to readability. The score is not an exact science, but is meant to help indicate the general complexity level of the page.

The readability score is calculated based on the number of words per sentence, and the number of syllables per word. For more information, see the Vale documentation.

Install linters

  1. Install prettier:

    npm install

  2. Install vale. To install for:

    • macOS using brew, run: brew install vale.
    • Linux, use your distribution's package manager or a released binary.

These tools can be integrated with your code editor.

Configure editors

Using linters in your editor is more convenient than having to run the commands from the command line.

To configure prettier in your editor, install one of the following as appropriate:
