# Project design
> Draft, submit, and review your Project Design Document and supporting evidence through Certify's structured requirements checklist
Your Project Design Document (PDD) as well as any supporting evidence can be drafted, submitted and reviewed through Certify.
Support for newer protocol or module requirements may be dependent on your project's pathway. Your Registry Operations Manager will be able to advise you on PDD drafting during your onboarding.
## Project requirements
Certify consolidates the requirements for your project into a single structured checklist.
Requirements are derived from:
1. The [Isometric Standard](https://registry.isometric.com/standard)
2. The [protocol](https://registry.isometric.com/protocols) your project will be credited under
3. Any [protocol modules](https://registry.isometric.com/modules) that apply to your project
The governing document that each requirement is derived from is linked from the Certify interface via the requirement source link icon. This will show a requirement shortcode (e.g. `R-NK7R-0`) and a link icon: .
## Requirement sections
Requirements are grouped into the following sections, navigated by tabs in the Project Design page:
1. Project setup
2. Protocol & monitoring
3. Environmental & social
4. Stakeholder input
5. Pathway specific
## PDD drafting
Follow the steps below to draft and submit your PDD for review.
Open the response form for each requirement by clicking the disclosure icon: .
Responses can be added inline, using rich-text markup features including:
* Headings
* Lists
* Tables
* Section breaks
* Hyperlinks
* Inline images
* Equations
* References (use the forward slash `/` command to add a reference)
Your responses are saved automatically as you edit.
To attach more detailed evidence to a response, click the ** Upload file** button and upload your source files. You'll be asked to provide a category (e.g. lab report, affidavit), the reason for attachment, and the relevant pages in the document.
* **Plan / Assessment**
Monitoring plans, MRV plans, implementation plans, baseline assessments, additionality assessments, risk assessments, sensitivity analyses, counterfactual analyses, leakage analyses, closure plans, EIAs, SIAs, LCAs, HSE plans

* **Permit / Certificate**

* **Contract / Affidavit**

* **Other**
Documents which do not neatly fit in the above categories
Use the progress bar at the bottom of the Project Design page to track outstanding responses. Any requirements or sections where a response is still required are marked with a "Not started" label. Selecting "Drafting stage > Not started" in the **Filter** menu will filter all requirements down to those that still require a response. You can update the drafting stage to **Peer Review** to manage internal signoff and to **Ready for Submission** when it is completed.
Remi, Isometric's AI agent, can give you early feedback on draft submissions before the pre-screen stage. Suggested issues will appear on your submission and in the central Log of Issues page. Run it as often as you'd like during drafting - on a single requirement, or on all Remi-enabled requirements at once via **Run all Remi reviews** (top right). To see which requirements support it, select **Remi review available** in the Filter menu. Re-running the review after making the requested updates will automatically resolve the issue. Otherwise, issues may be marked as addressed, or disputed in order to submit the Project Design for pre-screen review.
When all responses are marked as **Ready for Submission**, the **Request validation** button in the bottom right of the screen will be enabled. You can then submit your PDD draft for pre-screen review.
Isometric will review your submission and, once all issues are addressed, send it to the verifier for validation.
On requesting a review from Isometric or the verifier, your response will be locked and cannot be edited until the review is completed.
On review, your responses will either be accepted, or issues may be raised by the reviewer (Isometric's internal team for pre-screen or your assigned Verifier for project validation). When issues are logged, you will be notified by email with a daily digest.
In Certify, responses with an open issue are assigned back to the Supplier. You can use the **Filter** menu to filter all responses down to those assigned to you where action is required.
After redrafting any responses with an open issue, mark the relevant issues as addressed. If you disagree with an issue, you can instead mark it as disputed and provide a comment explaining your rationale. You can also comment on any issue to ask for clarification or further guidance from the reviewer.
Once all issues have been addressed or disputed, click **Request review** to re-submit your PDD for review.
## PDD publication
Once the PDD has passed through pre-screen, your Registry Operations Manager will agree any required redactions of sections containing commercially sensitive or personal information, before publishing a copy to Isometric's registry for the project's [public comment period](https://docs.isometric.com/user-guides/certify/validation).
