Keep onboarding aligned with the source of truth
When the README evolves, your onboarding story can evolve with it.
Trigger
GitHub Repository README Changed
Triggers when the README file in a specific repository directory changes. Monitors the README in a configurable directory and branch/tag/commit. The payload includes the current README metadata (filename, path, SHA, size, URLs), the previous and current git blob SHAs, and a list of which tracked fields changed.
Action
Generate a Gamma
Create a new gamma generation. use to produce an ai-generated presentation/content. docs: https://developers.gamma.app/reference/generate-a-gamma
Why this helps
Founders repeat setup and product explanations because onboarding materials drift from the repository.
- Reduce repeated onboarding conversations
- Keep guidance synchronized with repository changes
- Help new collaborators reach productive work sooner
Setup
Build it in a few focused steps.
- 1Connect GitHub and Gamma to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to create it in plain language.
- 3Tell Notis to generate a Gamma onboarding deck whenever the repository README changes, highlighting updated setup, architecture, workflows, and first steps.
- 4Choose the README change trigger, select a reporting channel, and test with one README update.
Questions about this workflow
Is this only for open source projects?
No. It works for private repositories and internal onboarding as well.
Can it focus on only setup changes?
Yes. Tell Notis to emphasize setup and contributor instructions.

New Workflow Artifact Created
Triggers when a new workflow artifact is created in a GitHub repository. Monitors for newly created GitHub Actions workflow artifacts. Optionally filters by artifact name to restrict monitoring to specific artifacts.
Branch Changed
Triggers when a GitHub branch changes. Monitors a specific branch for: - New commits pushed (head commit SHA changes) - Protection status toggled (branch becomes protected or unprotected) - Protection settings changed, including: required status checks and their enforcement level, admin enforcement, required pull request reviews (dismiss stale reviews, code owner reviews, approving review count, last push approval), required linear history, force push allowance, deletion allowance, conversation resolution, branch locking, and fork syncing.
New Branch Created
Triggers when a new branch is created in a GitHub repository. Detects newly created branches. Deleted branches do not fire events.
Check Run Status / Conclusion Changed
Triggers when a specific GitHub check run changes its status or conclusion. Monitors a single check run for changes to: status (queued, in_progress, completed, etc.), conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required), started_at, and completed_at.
Check Suite Status / Conclusion Changed
Triggers when a GitHub check suite changes its status or conclusion for a given ref. Monitors all check suites associated with a git reference (branch, tag, or commit SHA) for changes to status (queued, in_progress, completed, etc.) and conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required, startup_failure, stale). Optionally filters by GitHub App ID.
New Code Scanning Alert Created
Triggers when a new code scanning alert is created in a repository. Fires an event for each newly created code scanning alert detected in the configured repository. Alerts can be filtered by Git reference, scanning tool, state, and severity. The payload includes the alert number, rule details, tool information, state, severity, and the location of the most recent instance.
