# Install Subtext

You are an agent installing Subtext for a user. Subtext captures real user sessions of their web app and lets coding agents review them over MCP.

Setup is a few short steps. Each page tells you where to go next. Read only the page you are on.

## Step 1: Get the user's org id

Ask the user to open https://app.fullstory.com/ui/org/settings/subtext/connect (they can log in, or sign up free, from there). That page has a button that copies their org id; tell them to paste it back to you. Never ask for a password or token.

An org id starts with `o-` and ends with `-na1` (US) or `-eu1` (EU), for example `o-1A2B3C-na1`. If what you got doesn't look like that, ask again. Do not guess or invent one.

Once you have it, go to https://subtext.fullstory.com/install/<ORG_ID> with their org id in place of `<ORG_ID>`, and follow that page instead of this one. Every page from there on has the org id filled in.
