# Quickstart

Install the CLI, run a session, and merge your first change request.

Canonical page: https://singulacomp.ai/docs/quickstart

This page takes you from a fresh terminal to a merged change request (CR).
Every command below is copy-pasteable.

### Install the CLI

Run the install script. It downloads the `singulacomp` binary for your OS.

```sh
curl -fsSL https://singulacomp.ai/install | bash
```

SingulaComp supports macOS and Linux. There is no Windows binary yet.

### Sign in

```sh
singulacomp login
```

This opens your browser for sign-in. After you sign in, `singulacomp login` picks
your account and a default [project](/docs/project) for you.

### Create or clone a project

A new account has no projects yet, so `singulacomp login` has none to pick. Run
`singulacomp init` with a name to create your first project. This scaffolds a
project directory on your machine.

```sh
singulacomp init my-app
cd my-app
singulacomp ship
```

`singulacomp ship` creates the project in SingulaComp Cloud on its first run, then
pushes your code. Run `singulacomp ship` again any time to sync local changes.

To work on a project that already exists in SingulaComp Cloud, clone it instead:

```sh
singulacomp projects clone <project-id>
```

Find `<project-id>` with `singulacomp projects ls`.

### Run a session

```sh
singulacomp sessions new --prompt "Build the login page"
```

This starts a [session](/docs/work/sessions). The agent works in its own
sandbox, on its own branch, so your project is not touched yet.

Attach to the session to watch progress and reply:

```sh
singulacomp sessions chat
```

### Review and merge the change request

When the agent finishes, it opens a change request with a summary and
the exact diff.

```sh
singulacomp cr ls
```

This lists the open CRs in your project. Review the one the agent opened, then
merge it to land the work on your default branch:

```sh
singulacomp cr merge 1
```

Replace `1` with the CR number from `singulacomp cr ls`. Nothing reaches your
project's default branch until you merge.
