+# Getting Started with Forte
+
+Welcome to Forte — your music store management platform.
+
+## Signing In
+
+1. Open Forte in your browser
+2. Enter your email and password
+3. Click **Sign in**
+
+If you don't have an account, ask your store manager to create one for you.
+
+## Navigation
+
+Use the sidebar on the left to navigate between sections:
+
+- **Accounts** — manage customer accounts and their members
+- **Members** — find and manage individual people across all accounts
+- **Help** — you're here!
+
+## Need Help?
+
+If you can't find what you're looking for, contact your store manager or system administrator.

+# Accounts
+
+An **account** is a billing entity — it could be a family, a business, a school, or an individual person. All billing, invoices, and payments are tied to an account.
+
+## Creating an Account
+
+1. Go to **Accounts** in the sidebar
+2. Click **New Account** in the top right
+3. Fill in the account name (e.g. "Smith Family" or "Lincoln Elementary")
+4. Optionally add email, phone, and address
+5. Add the **primary contact** — this is the main person on the account
+6. Click **Create Account**
+
+**Tip:** If you leave the account name blank and fill in the primary contact, the account name will be automatically set to the person's name.
+
+## Account Details
+
+Click any account in the list to see its details. The detail page has tabs:
+
+- **Overview** — edit account name, contact info, billing mode
+- **Members** — people on the account (family members, students, etc.)
+- **Payment Methods** — cards on file
+- **Tax Exemptions** — tax-exempt certificates
+- **Processor Links** — payment processor connections
+
+## Searching
+
+Use the search bar to find accounts by name, email, phone, or account number. You can also find accounts by searching for a member's name.
+
+## Account Numbers
+
+Every account gets a unique 6-digit number automatically. This number appears in the account list and can be used for quick lookup.
+    `.trim(),
+  },
+  {
+    slug: 'members-overview',
+    title: 'Members Overview',
+    category: 'Accounts',
+    content: `
+# Members
+
+A **member** is an individual person associated with an account. This could be a parent, a child, a student, a band director — anyone who takes lessons, rents instruments, or needs to be tracked.
+
+## Adding a Member
+
+1. Go to an account's **Members** tab
+2. Click **Add Member**
+3. Enter first and last name (required)
+4. Optionally add email, phone, date of birth
+5. Click **Add Member**
+
+**Tip:** If you don't provide email, phone, or address, the member will automatically inherit these from the account.
+
+## Minor Flag
+
+If a member is under 18, they're flagged as a **Minor**. This happens automatically if you enter a date of birth. If the family prefers not to share a birthday, you can check the "This person is a minor" box instead.
+
+## Member Numbers
+
+Like accounts, every member gets a unique 6-digit number for quick reference.
+
+## Finding Members
+
+Use the **Members** page in the sidebar to search across all members in all accounts. Click a member to go to their account.
+
+## Moving a Member
+
+If a member needs to be moved to a different account (e.g. a student aging out and getting their own account), ask your administrator — members can be reassigned between accounts.

+# Payment Methods
+
+Payment methods are cards on file for an account. These are used for recurring billing (rentals, lessons) and in-store purchases.
+
+## Adding a Payment Method
+
+1. Go to an account's **Payment Methods** tab
+2. Click **Add Method**
+3. Select the processor (Stripe or Global Payments)
+4. Enter the payment method ID from the processor
+5. Optionally enter card brand, last four digits, and expiration
+6. Click **Add Payment Method**
+
+**Note:** Card details are stored securely with the payment processor — Forte only keeps a reference and display info (last 4 digits, brand).
+
+## Default Payment Method
+
+One payment method can be marked as the **default**. Click the star icon next to a method to make it the default. The previous default is automatically unset.
+
+## Needs Update Flag
+
+If a payment method was migrated from an old system, it may show a "Needs Update" badge. This means the customer needs to re-enter their card information.

+# Tax Exemptions
+
+Schools, churches, and resellers may be exempt from sales tax. Forte tracks tax exemption certificates per account.
+
+## Adding a Tax Exemption
+
+1. Go to an account's **Tax Exemptions** tab
+2. Click **Add Exemption**
+3. Enter the certificate number (required)
+4. Optionally add certificate type (e.g. "resale"), issuing state, and expiration date
+5. Click **Add Tax Exemption**
+
+The exemption starts in **Pending** status.
+
+## Approving an Exemption
+
+A manager must verify the certificate and approve it:
+
+1. Click the **check mark** icon next to a pending exemption
+2. The status changes to **Approved**
+
+## Revoking an Exemption
+
+If a certificate expires or is no longer valid:
+
+1. Click the **X** icon next to an approved exemption
+2. Enter a reason for revoking
+3. The status changes back to **None**
+
+All approvals and revocations are logged with who did it and when.
