Figure - Contributing new content

The previous figure presents the basic steps for new docs contributions.

To contribute new content pages or improve existing content pages, open a pull request (PR):

  • If your change is small, or you’re unfamiliar with Git, read Changes using GitHub to learn how to edit a page.
  • If your changes are large, read Work from a local fork to learn how to make changes locally on your computer.

Changes using GitHub

If you’re less experienced with Git workflows, here’s an easier method of opening a pull request. Figure 1 outlines the steps and the details follow.

Figure 1. Steps for opening a PR using GitHub.

  1. On the page where you see the issue, select the Edit this page option in the right-hand side navigation panel.

  2. If you’re not a member of the project, GitHub will offer to create a fork of the repository. Select Fork this repository.

  3. Make your changes in the GitHub editor.

  4. Below the editor, fill in the Propose file change form.

  5. Select Propose file change.

  6. Select Create pull request.

  7. The Open a pull request screen appears. Your description helps reviewers understand your change.

  8. Select Create pull request.

Before merging a pull request, OpenTelemetry community members review and approve it.

If a reviewer asks you to make changes:

  1. Go to the Files changed tab.
  2. Select the pencil (edit) icon on any files changed by the pull request.
  3. Make the changes requested. If there’s a code suggestion, apply it.
  4. Commit the changes.

When your review is complete, a reviewer merges your PR and your changes goes live a few minutes later.

Work from a local fork

If you’re more experienced with Git, or if your changes are larger than a few lines, work from a local fork.

Make sure you have git installed on your computer. You can also use a user interface for Git.

Figure 2 shows the steps to follow when you work from a local fork. The details for each step follow.

Figure 2. Working from a local fork to make your changes.

Fork the opentelemetry.io repository

  1. Navigate to the opentelemetry.io repository.
  2. Select Fork.

Create a local clone and set the upstream

  1. In a terminal window, clone your fork and install the requirements:

    git clone git@github.com:<your_github_username>/opentelemetry.io.git
    cd opentelemetry.io
    npm install
    
  2. Set the open-telemetry/opentelemetry.io repository as the upstream remote:

    git remote add upstream https://github.com/open-telemetry/opentelemetry.io.git
    
  3. Confirm your origin and upstream repositories:

    git remote -v
    

    Output is similar to:

    origin	git@github.com:<your_github_username>/opentelemetry.io.git (fetch)
    origin	git@github.com:<your_github_username>/opentelemetry.io.git (push)
    upstream	https://github.com/open-telemetry/opentelemetry.io.git (fetch)
    upstream	https://github.com/open-telemetry/opentelemetry.io.git (push)
    
  4. Fetch commits from your fork’s origin/main and open-telemetry/opentelemetry.io’s upstream/main:

    git fetch origin
    git fetch upstream
    

    This makes sure your local repository is up to date before you start making changes. Push changes from upstream to origin regularly to keep you fork in sync with upstream.

Create a branch

  1. Create a new branch. This example assumes the base branch is upstream/main:

    git checkout -b <my_new_branch> upstream/main
    
  2. Make your changes using a code or text editor.

At any time, use the git status command to see what files you’ve changed.

Commit your changes

When you are ready to submit a pull request, commit your changes.

  1. In your local repository, check which files you need to commit:

    git status
    

    Output is similar to:

    On branch <my_new_branch>
    Your branch is up to date with 'origin/<my_new_branch>'.
    
    Changes not staged for commit:
    (use "git add <file>..." to update what will be committed)
    (use "git checkout -- <file>..." to discard changes in working directory)
    
    modified:   content/en/docs/file-you-are-editing.md
    
    no changes added to commit (use "git add" and/or "git commit -a")
    
  2. Add the files listed under Changes not staged for commit to the commit:

    git add <your_file_name>
    

    Repeat this for each file.

  3. After adding all the files, create a commit:

    git commit -m "Your commit message"
    
  4. Push your local branch and its new commit to your remote fork:

    git push origin <my_new_branch>
    
  5. Once the changes are pushed, GitHub lets you know that you can create a PR.

Open a pull request from your fork

Figure 3. Steps to open a PR from your fork to the opentelemetry.io.

  1. In a web browser, go to the opentelemetry.io repository.

  2. Select New Pull Request.

  3. Select compare across forks.

  4. From the head repository drop-down menu, select your fork.

  5. From the compare drop-down menu, select your branch.

  6. Select Create Pull Request.

  7. Add a description for your pull request:

    • Title (50 characters or less): Summarize the intent of the change.

    • Description: Describe the change in more detail.

      • If there is a related GitHub issue, include Fixes #12345 or Closes #12345 in the description. GitHub’s automation closes the mentioned issue after merging the PR if used. If there are other related PRs, link those as well.
      • If you want advice on something specific, include any questions you’d like reviewers to think about in your description.
  8. Select the Create pull request button.

Your pull request is available in Pull requests.

After opening a PR, GitHub runs automated tests and tries to deploy a preview using Netlify.

  • If the Netlify build fails, select Details for more information.
  • If the Netlify build succeeds, select Details opens a staged version of the OpenTelemetry website with your changes applied. This is how reviewers check your changes.

Other checks might also fail, including:

  • File name checks
  • Links resolution
  • Markdown formatting
  • Spelling

GitHub also automatically assigns labels to a PR to help reviewers.

Fix content issues automatically

Before submitting a change to the repository, run the following command and (i) address any reported issues, (ii) commit any files changed by the script:

npm run test-and-fix

To separately test and fix all issues with your files, run:

npm run test    # Checks but does not update any files
npm run fix:all # May update files

To list available NPM scripts, run npm run.

Preview your changes locally

Preview your changes locally before pushing them or opening a pull request. A preview lets you catch build errors or markdown formatting problems.

To build and serve the site locally with Hugo, run the following command:

npm run serve

Navigate to https://localhost:1313 in your web browser to see the local preview. Hugo watches the changes and rebuilds the site as needed.

To stop the local Hugo instance, go back to the terminal and type Ctrl+C, or close the terminal window.

Site deploys and PR previews

If you submit a PR, Netlify will create a deploy preview so that you can review your changes. Once your PR is merged, Netlify deploys the updated site to the production server.

Note: PR previews include draft pages, but production builds do not.

To see deploy logs and more, visit project’s dashboard – Netlify login required.

PR guidelines

Before a PR gets merged, it will sometimes require a few iterations of review-and-edit. To help us and yourself make this process as easy as possible, we ask that adhere to the following:

  • If your PR isn’t a quick fix, then work from a fork: Click the Fork button at the top of the repository and clone the fork locally. When you are ready, raise a PR with the upstream repository.
  • Do not work from the main branch of your fork, but create a PR-specific branch.
  • Ensure that maintainers are allowed to apply changes to your pull request.

Changes from reviewers

Sometimes reviewers commit to your pull request. Before making any other changes, fetch those commits.

  1. Fetch commits from your remote fork and rebase your working branch:

    git fetch origin
    git rebase origin/<your-branch-name>
    
  2. After rebasing, force-push new changes to your fork:

    git push --force-with-lease origin <your-branch-name>
    

You can also solve merge conflicts from the GitHub UI.

Merge conflicts and rebasing

If another contributor commits changes to the same file in another PR, it can create a merge conflict. You must resolve all merge conflicts in your PR.

  1. Update your fork and rebase your local branch:

    git fetch origin
    git rebase origin/<your-branch-name>
    

    Then force-push the changes to your fork:

    git push --force-with-lease origin <your-branch-name>
    
  2. Fetch changes from open-telemetry/opentelemetry.io’s upstream/main and rebase your branch:

    git fetch upstream
    git rebase upstream/main
    
  3. Inspect the results of the rebase:

    git status
    

    This results in a number of files marked as conflicted.

  4. Open each conflicted file and look for the conflict markers: >>>, <<<, and ===. Resolve the conflict and delete the conflict marker.

    For more information, see How conflicts are presented.

  5. Add the files to the changeset:

    git add <filename>
    
  6. Continue the rebase:

    git rebase --continue
    
  7. Repeat steps 2 to 5 as needed.

    After applying all commits, the git status command shows that the rebase is complete.

  8. Force-push the branch to your fork:

    git push --force-with-lease origin <your-branch-name>
    

    The pull request no longer shows any conflicts.

Merge requirements

Pull requests are merged when they comply with the following criteria:

  • All reviews by approvers, maintainers, technical committee members, or subject matter experts have the status “Approved”
  • No unresolved conversations
  • Approved by at least one approver
  • No failing PR checks
  • PR branch is up-to-date with the base branch

Important

Do not worry too much about failing PR checks. Community members will help you to get them fixed, by either providing you with instructions how to fix them or by fixing them on your behave.

Open an issue

If you want to suggest improvements to existing content or notice an error, open an issue.

  1. Click the Create documentation issue link on any document. This redirects you to a GitHub issue page prepopulated with some headers.
  2. Describe the issue or suggestion for improvement. Provide as many details as you can.
  3. Click Submit new issue.

After submitting, check in on your issue occasionally or turn on GitHub notifications. It might take a few days until maintainers and approvers respond. Reviewers and other community members might ask questions before they can take action on your issue.

Suggesting new content or features

If you have an idea for new content or a feature, but you aren’t sure where it should go, you can still file an issue. You can also report bugs and security vulnerabilities.

  1. Go to GitHub and select New issue inside the Issues tab.

  2. Select the type of issue that best applies to your request or doubt.

  3. Fill out the template.

  4. Submit the issue.

How to file great issues

Keep the following in mind when filing an issue:

  • Provide a clear issue description. Describe what specifically is missing, out of date, wrong, or needs improvement.
  • Explain the specific impact the issue has on users.
  • Limit the scope of a given issue to a reasonable unit of work. For problems with a large scope, break them down into smaller issues. For example, “Fix the security docs” is too broad, but “Add details to the ‘Restricting network access’ topic” is specific enough to be actionable.
  • Search the existing issues to see if there’s anything related or similar to the new issue.
  • If the new issue relates to another issue or pull request, refer to it either by its full URL or by the issue or pull request number prefixed with a # character. For example, Introduced by #987654.
  • Follow the Code of Conduct. Respect your fellow contributors. For example, “The docs are terrible” is not helpful or polite feedback.

Contribute to other repositories

OpenTelemetry is an open source project, and we gladly accept new contributions and contributors. See the CONTRIBUTING.md file in each SIG repository for information on getting started.

Individual SIGs may maintain documentation above and beyond what is offered here, but we strive for accurate general guidance on using the project from our main website.

If you see text you’d like to improve, use GitHub to search all repositories in the OpenTelemetry organization. This can help you figure out where to submit your issue or PR. Each repository has its own processes and procedures. Before you file an issue or submit a PR, read that repository’s README.md, CONTRIBUTING.md, and code-of-conduct.md, if they exist.

Most repositories use issue and PR templates. Have a look through some open issues and PRs to get a feel for that team’s processes. Make sure to fill out the templates with as much detail as possible when you file issues or PRs.

Other ways to contribute
