Getting started — from sign-up to your first seal

All you need is an email address and a computer with Obsidian. Everything in this guide is done once — after that, you just write.

1. Create an account

Sign up at nanalstamp.com/join with an email and password. Click the verification link in the email — login is blocked until you do.

2. Install the plugin and log in

In Obsidian, open Settings → Community plugins and install nanalStamp, then enable it. A seal icon appears in the left ribbon and the status bar shows "🔑 login required." Log in under Settings → nanalStamp — your API key is issued automatically, so there is nothing else to create.

3. Choose folders to seal — the step that matters most

Logging in does not seal anything yet. You decide which folders become records — nothing starts before you choose, and that is by design.

In the modal that appears after login, pick the folders to seal (for example, Lab notes) and apply. Checking a parent folder includes everything under it. Notes outside the scope are never sealed, no matter how much you edit them — your private notes stay private.

4. Where past versions accumulate

In the same modal, confirm the local archive location (default ~/nanalStamp-archive). Every seal stores that moment's full text here as a version. There is no off switch — only a location choice — because preserving originals is the premise of the service. On the free tier this folder is the only place your originals live, and it exists on this device only. Lose the device, lose the originals — cloud storage is covered in the subscription guide.

5. Ready

When the status-bar warning changes to "nanalStamp · 0 sealed," you're set. Log in at nanalstamp.com/home to see the same state on the web. Now, just write.
