New Domain

0 / 18 steps

Phase 1 Before Touching DNS — Identify Nameservers

account.squarespace.com → Domains → Register. Use .com where possible.

account.squarespace.com → Domains → Register New Domain

Identify authoritative nameserver (CRITICAL)

Run this BEFORE making any DNS changes. Determines where to make changes.

nslookup -type=NS DOMAIN.COM 8.8.8.8

Confirm: Microsoft 365 is the authority for saludcap.com sub-ventures

Expected NS: bdm.microsoftonline.com. If different, DNS changes go elsewhere.

admin.microsoft.com → Settings → Domains → saludcap.com

Phase 2 GitHub Repository Setup

Create GitHub repository under SaludCap org

github.com/organizations/SaludCap → New repository. Set to Public for GitHub Pages.

github.com/organizations/SaludCap/repositories/new

Clone repo locally and add index.html

git clone https://github.com/SaludCap/REPO-NAME.git

Create CNAME file in repo root

File named exactly "CNAME" (no extension) containing only the domain name.

echo "DOMAIN.COM" > CNAME && git add CNAME && git commit -m "Add CNAME" && git push

Enable GitHub Pages

Repo Settings → Pages → Source: main branch, /(root). Do NOT set custom domain yet.

github.com/SaludCap/[repo] → Settings → Pages → Source: main / (root)

Phase 3 Add DNS Records (Microsoft 365)

Add GitHub Pages A records (4 records)

In Microsoft 365 DNS. Type: A, Host: @, TTL: 3600

Type	Host	Value	TTL
A	@	185.199.108.153	3600
A	@	185.199.109.153	3600
A	@	185.199.110.153	3600
A	@	185.199.111.153	3600

Add CNAME record for www

Type	Host	Value	TTL
CNAME	www	saludcap.github.io	3600

Add GitHub domain verification TXT record

Get the TXT value from GitHub → Settings → Pages → Verify Domain

Type	Host	Value
TXT	_github-challenge-SaludCap-org.DOMAIN.COM	Get from GitHub Pages settings

Phase 4 Verify & Activate HTTPS

Verify A records are propagating

nslookup -type=A DOMAIN.COM 8.8.8.8

Check propagation at whatsmydns.net

https://www.whatsmydns.net/#A/DOMAIN.COM

Set custom domain in GitHub Pages

Repo Settings → Pages → Custom domain → enter domain → Save. Wait for DNS check to pass.

github.com/SaludCap/[repo] → Settings → Pages → Custom domain → DOMAIN.COM

Enforce HTTPS

Repo Settings → Pages → ✓ Enforce HTTPS. May take a few minutes after DNS check passes.

Hard-refresh and confirm site is live at HTTPS domain

https://DOMAIN.COM — open in incognito, Ctrl+Shift+R

Phase 5 Standard Deploy Commands

Normal push (branch up to date)

git add -A && git commit -m "description" && git push origin main

If rejected (branch behind remote)

rm CNAME && git pull origin main && git push origin main

If vim merge editor opens

:wq [Enter] — saves merge commit and exits vim
