Run Envelope on your computer.

100% free and open source. Two lines, and Envelope opens in your browser.

1
Install rer
```
curl -fsSL https://runeditrun.com/install.sh | sh
```
It installs rer for you alone, with its own Node if you have no Node 22 or later. The installer does not edit your shell files itself. If it ends with a line to run, run it before step 2: it puts rer on your PATH now and appends the same setting to your shell's startup file (for example ~/.zshrc) for new terminals.
2
Start Envelope
```
rer dev just-every/run-envelope
```
rer gets Envelope, installs everything, makes you the owner and prints a link that opens Envelope signed in. To start it again later: cd run-envelope && rer dev
Already have Node 22 or later? npx -y @runeditrun/rer dev just-every/run-envelope does both steps in one line.
