# User guide
> Get started with the Keldyn web app: sign up, set up your organization, invite your team, and create your first use case.
This guide walks you through the basics of the Keldyn web app — from creating your account to assessing your first AI use case. The app lives at [app.keldyn.ai](https://app.keldyn.ai).
Here's the path a new user follows:
## Create your account
Go to [app.keldyn.ai/register](https://app.keldyn.ai/register). You can sign up with **Google** or **Microsoft**, or use the email form below the **Or continue with email** divider.
Provide your details, then agree to the Terms of Service and Privacy Policy:
| Field | Required | Notes |
| ---------------- | -------- | --------------------------------------------------------------------------------- |
| First name | Yes | |
| Last name | No | |
| Email address | Yes | Use your work email |
| Password | Yes | At least 8 characters, with an uppercase letter, a lowercase letter, and a number |
| Confirm password | Yes | Must match your password |
Select **Create account**.
Open the verification link Keldyn sends to your inbox, then sign in at [app.keldyn.ai/login](https://app.keldyn.ai/login) with your email and password. If you signed up with Google or Microsoft, your email is already verified.
Forgot your password? On the login page, select **Forgot password?**, enter your email, and follow the reset link Keldyn sends you.
**Joining from an invitation?** Open the invite link from your email. If you don't have an account yet, you'll sign up with the invitation attached and join the team automatically. If you already have an account, sign in and select **Accept** on the **Team Invitation** prompt.
## Set up your organization
The first time you sign in, Keldyn takes you to a short onboarding questionnaire. It uses your answers to tailor the frameworks, controls, and risk analysis it recommends.
Organization setup is required. Until you finish it, only **User Settings** and **Notifications** are available in the sidebar. The dashboard and use cases unlock once you submit.
On the **Welcome to Keldyn** screen, enter your **Organization name**.
Work through the sections based on your current operations — organization profile, services and customers, geography, data and operations, regulatory landscape, teams and maturity, risk and controls, and policies. A few answers are required, including your **organization type** and whether you have a **Data Protection Officer (DPO)**.
Use **Add other** to list regulations or frameworks that aren't already offered. Under **Framework Documents**, you can optionally drag and drop policy files (PDF, DOC, DOCX, TXT, Markdown, YAML, or Mermaid) and tag each with the frameworks it applies to.
Select **Next** to review the **Organization Summary** and each section. Select **Back** to fix anything, then **Submit**. You'll see a **Welcome to Keldyn!** confirmation.
Use **Save draft** to keep your progress and finish later. To review or change your profile afterward, open **My Organization** in the sidebar and select **Edit Organization**.
## Invite your team
Keldyn organizes work into **teams** (workspaces). Everything you do belongs to the team you're currently in, and you can switch teams using the **team switcher** in the sidebar.
In the sidebar, select **Team Management** to see your members, pending invites, and roles.
Select **Invite Member**, enter the person's **Email address**, choose a **Role**, and select **Send Invitation**. The invite appears under **Pending Invitations** until they accept.
From Team Management you can also change or remove members, cancel pending invitations, and create custom roles under **Role Management**.
Inviting members, removing members, and changing roles require the right permissions. If you don't see these actions, ask a workspace owner or admin.
## Create a use case
A **use case** represents an AI system or project you want to assess and govern. Keldyn uses it to draft security and compliance requirements, map frameworks, and build an architecture model.
From the **Dashboard** or **Use Cases** page, select **New Use Case**. On **Start a new use case**, choose how to begin:
* **Build a new project** — describe your idea and let Keldyn draft the assessment. No documents required.
* **Assess an existing system** — review a system you already run to uncover requirements.
Select **Continue** on the option you want.
Describe your use case in the main text box. If you're assessing an existing system, upload and tag your project documents (architecture, data flow, requirements). Answer the required **key facts** (such as product type, personal data, and EU/EEA data subjects) — select **Fill from description** to pre-fill them, review, then check **I confirm these key facts are accurate**. Select **Start Assessment**, and when it finishes, select **Continue**.
Prefer to enter everything yourself? Choose the manual wizard and complete three steps:
1. **Project Basics** — name, description, owner, business area, risk level, status, and business objective.
2. **Framework Alignment** — click framework cards to select the ones this use case must support.
3. **Architecture** — answer the architecture questions that adapt to your selected frameworks.
Select **Submit** to create the use case.
After creation, Keldyn generates the architecture and opens the use case workspace, where you can review requirements, work through controls, and manage frameworks. Your use cases are always available under **Use Cases** in the sidebar.
## Next steps
Generate an architecture, run security analysis, and track progress in the workspace.
Enable frameworks and track control implementation across your organization and use cases.
Attach evidence to controls and measures, and manage audits and certifications.
Set up the Keldyn MCP server so assistants can query controls and track evidence on your behalf.
