Introduction to Basic GitHub Contribution

Many first-time users are intimidated by Git and GitHub, and they are indeed not simple tools. Most of the guides out there concentrate on how one does contribute to the documents, sources, etc, on a GitHub repository, how to change, commit, etc. However, in groups (like W3C Working Group) there may be a number of participants who would like first to understand what the basics are to raise issues, comment on them, notified about them: this is, for many, the first step in collaborating. This introduction is for them.

GitHub are a way to comment on documents or other sources, and have threads of discussions. Issues can be labelled, referred to via a URL, and GitHub offers powerful ways of searching through the issues. As a consequence, many groups prefer to use the GitHub issue facilities to manage comments. Here are the steps that you have to follow to get up to speed quickly.

  1. Get a GitHub account
  2. Issue creation and commenting
    1. Create a new issue
    2. Comment on an issue
  3. Be notified!
    1. Set up your notification preferences
    2. “Watch” a specific repository
  4. Bonus: combining email with issue commenting
  5. Propose a simple change on a document

Get a GitHub account

If you haven’t yet, get yourself an account. You will have to choose a nickname, and provide an email address, too. The email address may used for various notifications (see below) so use an email address that you use regularly for your work, too.

The nickname is also a powerful tool to refer to another person in an issue, a comment, etc. E.g., if my nickname (iherman) appears in the form @iherman in an issue and/or a comment, I am notified of that comment, and an active link to my profile is also automatically generated in the comment on-line. It has become a habit on GitHub to use the nickname rather than one’s name in a comment.

Issue creation and commenting

Create a new issue

Nothing could be simpler. Go to the repository, look for the tab Issues and then push the New Issue. You will get something like this:

Give a suitable title, type your issue in the edit box, and push the ‘Submit New Issue’ button. That is it.

The edit box understands the markdown syntax, and the content will be displayed properly formatted.

You do not necessarily have to understand all the details of the syntax; the edit box has some helping buttons if you want to change the font size, etc.

An issue can also be categorized (“labelled”) although you do not necessarily have the right to label the issue yourself (this has to be done by those who have an “admin” right to that repository).

The issues are automatically numbered by GitHub, and given a URL of the form https://github.com/{repository name}/issues/25. As further help, you can refer from one issue (and its comments) to another within the same repository by simply typing, e.g., #25; GitHub expands this into the issue URL.

Comment on an issue

You can “open” and issue by using its URL, and you can then add a comment on the issue. The page displayed by GitHub automatically creates a similar edit area than for a new issue: just type into it, and push “Comment”. See the figure below as an example

You can also decide to close an issue (for example, because your question was answered); closed issues are displayed separately, but they are not removed (and can be re-opened at any time).

Actually, reacting on an issue may be even simpler; it can be done by email! However, that requires some more step on notifications first.

When your comment is simply an agreement or a disagreement on another comment, it is a good idea to use the small emoji icon on the upper right hand corner of the editing box. The emojis get displayed but do not use up much space…

Be notified!

Creating and commenting on issues is fine, but you have to know that there is something interesting happening. For that, some prefer to receive automatic notifications via emails. This includes two steps:

  1. Set up your notification preferences
  2. “Qatch” a specific repository

Set up your notification preferences

This can be done in your personal setting; these can be reached by through the pull down menu on the upper right hand corner of the screen where your avatar should appear. Look for “Settings”. Once you are there, look (usually on the left hand side) at “Notifications”.

You will see different choices. You can choose “email” for

In case you choose for email notifications you can also set which events you will be notified on exactly; I would suggest to set all options, they can be removed later.

As an example, here is how my notification settings look like:

“Watch” a specific repository

That is easy: if you go to a repository page you are interested it, look for the pull-down menu on the top that says “Watch”, and choose the option you prefer.

Bonus: combining email with issue commenting

The advantage of using a notification is that you do not only receive an email on any new issue raised or commented upon, but you can also use your client for adding a new comment.

An email coming from github can be easily recognized (see illustration):

If you receive such a mail, and you want to comment, you have two possibilities

  1. you use the link in the footer to go to the Web interface
  2. you reply to this mail with your comments; GitHub will insert your reply as a bona fide comment to the issue, just as if you did it directly.

It is good practice to remove your automatic signature, if any, from the returned email, as well the possibly long thread of earlier replies either as part of the text or attached. Quote only what is really relevant. It keeps the issue list cleaner

There are pros and cons on using email for comments or respond via a Web interface. The former can be very convenient and quick, the latter allows you to edit your comments more easily and preview the markdown. At the end of the day, this is a personal choice.

Propose a simple change on a document

Direct contribution to content may become more complex, and would require a more extensive knowledge of Git. (See, for example, the GitHub “Hello World!” for some more info.) But some simple editorial change (or proposal thereof) is relatively easy.

Say you want to make some editing on an on the index.html file in a specific repository.

start editing on a file in the repo by pushing the pen icon

choices on committing the editorial changes

That is it. The rest is in the hands of the repository administrator

The result of this action creates, actually, a special issue on the repository that can be “acted” upon. Such an issue is called a “pull request” in the GitHub jargon. “Accepting” such a pull request means that the changes are incorporated. This also means that people can comment on that pull request (just as for any other issue) and will be notified about the change proposal.
