# Browser extension and link previews

## The browser extension

**LogiKFlow for GitHub** adds a small LogiKFlow button to the bottom-right corner of every GitHub pull request page, so it never covers the diff. A dot on it shows the status: green when a reading order exists, amber when it needs an update, none when there's no order. By default the button is Flo, the LogiKFlow mascot, who blinks, follows your cursor and waves when you hover. If you'd rather have a plain icon, open the extension's popup from the toolbar and choose **Icon** under **Button on GitHub**; the change applies right away. Hover over the button, or tab to it, to expand it into **Open in LogiKFlow** with a badge that tells you at a glance:

- **Reading order · 4 sections · by octo:** an order exists. Click to open it.
- **needs update:** commits were pushed after the order was saved.
- **No reading order yet · arrange it:** there's no order, and you can write to the repository. The button opens straight into arrange mode.
- **Sign in to see the order:** sign in to LogiKFlow in the same browser.

It works in Chrome, Edge, Brave, Arc and other Chromium browsers.

### Install

Until it's listed in the Chrome Web Store:

1. [Download the extension package](/downloads/logikflow-extension.zip) and unzip it.
2. Open `chrome://extensions` and turn on **Developer mode**.
3. Choose **Load unpacked** and select the unzipped folder.

The extension's toolbar icon opens a small menu: **Open LogiKFlow**, and the choice between Flo and a plain icon for the button on GitHub.

### Privacy

The extension only runs on `github.com` and only talks to `logikflow.dev`. It sends the repository and pull request number of the page you're viewing, using your existing sign-in, and stores nothing but your button choice. It can't read or reach any other site.

## Link previews in Slack, Teams and elsewhere

When you paste a LogiKFlow review link into Slack, Microsoft Teams, Discord, LinkedIn or similar, it shows a preview card.

- **Public repositories:** the card shows the pull request title, the section outline (for example *Flag and schema → Invite model and service → API*), the number of changed files, and how many reviewers have started.
- **Private repositories:** the card is generic, "Pull request review · LogiKFlow". The services that fetch previews aren't signed in, so LogiKFlow never shows them private details.

The preview image and text for public pull requests are refreshed every few minutes.
