Github at cc-ai : getting started

Hello and welcome to the CCAI GitHub!

In this repository, we will of course share code, but also links, articles, websites, and ideas. We will also use it for defining who does what task (i.e. ticket) and follow the progress of tickets and tasks as they evolve.

Dont worry if youve never used GitHub before! You can actually use GitHub without knowing ANY code at all. Its really a straightforward tool, and this document will help you cover the basics.

Git

Git is a software to do version control, which means it will save any changes being done without overwriting any past work. This means that even if several people are working on the same file at the same time, each person can upload their changes to the page, and Git will save both copies. Later, they can be merged together without anyone losing their work. You can even go back to a previous version at any point, because Git will keep a history of every change ever made. Typically, git is used via a terminal or command line and stores the versions on your computer. But GitHub allows us to store the content and versions online ; plus, it adds a user interface on top of Git, which makes it possible to download and change files from your browser or your desktop, make comments, suggest fixes, etc.

Vocabulary

Some useful GitHub vocabulary (from this guide)

Markdown: A way to write text files so that they are rendered beautifully on Github without the hastle of using html. For instance, if you start a line with # This is a title, it will be rendered by Github as a Top-level title (as # Github at cc-ai : getting started ). If you add a # it will be displayed as a secondary title (as ## Vocabulary ) and so on until ###### minor title. Including links is extremely easy too! [website](https://website.com) will be rendered like this: website. These special text files have a .md extension. On GitHub if there is a Readme.md file in the current folder youre looking into, it will be automatically rendered. If you click on a specific .md file, it will also be rendered. To see the raw text, before rendering, you can just click on the raw button (no shit). Remember: Markdown is easy, ask for help if youre stuck with something. In the mean time, checkout this cheatsheet to learn in 2 minutes how to use Markdown

Repository or Repo : A directory or storage space where your projects can live. It can be local to a folder on your computer, or it can be a storage space on GitHub or another online host. You can keep code files, text files, image files, you name it, inside a repository.

Commit: This is the command that gives Git its power. When you commit, you are taking a snapshot of your repository at that point in time, giving you a checkpoint to which you can reevaluate or restore your project to any previous state.

Branch: How do multiple people work on a project at the same time without Git getting them confused? Usually, they branch off of the main project with their own versions full of changes they themselves have made. After theyre done, its time to merge that branch back with the master, the main directory of the project.

Issue: Although the name may sound negative (Oh no, theres an issue with my project!) , issue is just the name used by GitHub for different tasks that contributors can assign to themselves. You can open an issue when youve defined it as something that needs to be worked on, tag it with labels depending on what it involves, and then assign it to yourself (or someone else!). A very important document that explains this workflow for the cc-ai project process can be found here.

What we will use GitHub for

  • Sharing code : for the coders among us, GitHub will be a way to test out different parameters, make changes to the code, clone (a.k.a.) copy other repositories that we can test, share results, etc. This will be done via the various repositories in the project, which can be seen at https://github.com/cc-ai

  • Tracking progress: Even if the task that you are working on doesnt involve coding (e.g. literature review, experimental testing, etc.), its useful for the rest of the team to know that you are working on a certain task (or issue), and what the progress on it is: whether it is open, closed, in progress, pending, etc. We will do this via the Kanban: https://github.com/cc-ai/kdb/projects/4

  • Sharing resources: A section of the repository is dedicated specifically to sharing common resources : https://github.com/cc-ai/kdb/tree/master/resources. These can be research papres, code, news articles, tools, etc. If you encounter something useful in your literature review (or even during your spare time!), add it to the resource section!

  • Sharing ideas: If you see an open ticket that is labelled as help wanted, or if you simply have an idea about a task that someone else is working on, dont hesitate to leave a comment on the issue: it can help open a discussion and generate new ideas!

  • Collaborating with external contributors: We are lucky enough to have a group of people interested in CCAI, who want to help us with different tasks depending on their domain of expertise: UI design, front-end development, economics.. the sky is the limit! To make this collaboration as smooth as possible, we want to give them specific tasks and ways to help us, check in with progress, ask questions, etc. GitHub is the place to do this!

Some Brief Tutorials

  • From the home page (https://github.com/cc-ai/kdb) click on resources in the top folder structure, then on papers (or the link provided): you should be at https://github.com/cc-ai/kdb/tree/master/resources/papers
  • Remember, by default, Github displays the file called Readme.md
  • You can edit this file and add your preferred paper by clicking on the pencil icon to the top right of the displayed Readme
  • Add a line with your paper line this * [paper title](https:// link to paper)

Adding a paper from a pdf

If you can simply add a link to this pdf, its better as it makes the hole repository heavier for others to sync with. But if you cant and want to share the file, heres how to:

  • Host it elsewhere (Google Drive or something)
  • Host it on the repository
    • From the home page (https://github.com/cc-ai/kdb) click on resources in the top folder structure, then on papers (or the link provided): you should be at https://github.com/cc-ai/kdb/tree/master/resources/papers
    • Click on Upload files
    • Drag and drop or choose your files
    • Commit (= save)
    • Copy link to file
  • Add the hosted file link to the Readme.md as described previously

Opening an issue

Why

Remember, issues are used to track problems, open discussions about a topic or simply create a task to be done. Basic use cases include:

  • Getting peoples opinion on a matter (like victo did for the whos who -> see #39)
  • Signaling a bug in some code (unexpected behavior, error in execution, installation issues and so on)
  • Reminding yourself (and possibly others) about something to be done (like the example issue below -> see #43 )

How

  • From the home page (https://github.com/cc-ai/kdb) click on issues in the top folder structure: this should bring you to https://github.com/cc-ai/kdb/issues
  • This will show you the list of currently open issues
  • You can filter the issues by Author, Labels, Assignee, or sort by date
  • To open a new issue, click on New Issue, in green at the top right of the list of open issues
  • When opening an issue, you should add: a title and a brief (one or two sentence) summary
  • Dont forget to label it with the corresponding label from the Labels dropdown list on the right (for more information about labels, read this: https://github.com/cc-ai/kdb/tree/master/workflow)
  • If you already know who will be working on the issue, add an Assignee from the list on the right. If not, you can leave it blank.

Assigning an issue to yourself

  • When you have found an issue that you want to tackle, possibly opened by someone else, click on its name
  • To assign it to yourself, click Assignees on the right of the screen and select your GitHub handle from the list
  • If you want to add details or comments, use the Write section at the bottom of the page

Closing an issue

  • When the issue is solved, use the close and comment button
  • You can always re-open an issue later if the fix is not complete or the same problem arises in a new context or whatever
  • For instance, the example issue above, #43, is now closed because gifs have been added

Bravo! Youre all set! Now checkout the workflows guide on using cc-ais labels on issues

Getting Started ∴

If you want to just dive in and get your hands dirty - go for it! Look at the tickets in the Kanban, choose the one that fits what you will start working on (check with Sasha or Karthik if you dont know what to pick), and get started!
