MemOS doesn't publish an install command for Windows anywhere we can verify, so there's nothing for us to show you. We won't invent one. It does document one for macOS and Linux — switch to that tab.
Pastes into PowerShell and installs MemOS on your Windows machine in one step. Runs as your normal user account, and needs no administrator rights.

Pastes into your terminal and installs MemOS on your macOS or Linux machine in one step — no manual setup, no build tools. It fetches the project's own install script and runs it, which is the standard way these tools ship — worth a read if you like to know what's running.
How to set up MemOS, step by step
Open Terminal. On a Mac it's in Applications ▸ Utilities, or press Cmd+Space and type Terminal. On Linux, press Ctrl+Alt+T. Paste the command and press Enter.
Run MemOS --help to see the available commands, and
MemOS --version to confirm the install worked. If your shell complains about
permissions, that project usually documents a corrected command on its own site.
This downloads the project's shell installer and pipes it straight into your shell, which executes it without saving a file. Same caveat: it's the project's script, but read it first if you want to be sure.

On mobile
MemOS is a command-line tool, so there is no phone app for it — a phone has no shell to run it in. You'll need a desktop, or a remote shell into a machine that has one.
MemOS is developed by its own authors. This page is an independent reference; we are not affiliated with or sponsored by the project. The command shown here was reproduced from the project's public documentation — always check the project's own documentation before running anything.
