Simplify contribution workflow

[colebemis]

Problem

Our current contribution workflow has a few problems:

• It requires contributors to clone the primer/octicons repo to their local machine.
• It requires familiarity with Git.
• It requires familiarity with SVG.
• There are a lot of unnecessary steps.

Here's a flowchart of the current contribution workflow:

Solution

Let's build a Figma plugin to allow contributors to open pull requests and commit to the primer/octicons repo directly from Figma. Here's a wireframe of what the plugin could look like:

The interface is modeled after the GitHub's web UI editor. Here's how I'm imagining the user flow would work:

1. Select the icon frames you want to add or update
2. Open the Figma plugin
3. Write a commit message (We could probably auto-populate a default commit message)
4. Click "Open pull request"
5. Plugin exports and optimizes the selected SVGs and creates a new branch.
6. Plugin redirects you to github.com to open a pull request with the new branch.
7. Write a detailed pull request description
8. Create pull request

Here's a flowchart showing how this plugin could simplify the contribution workflow:
