+title: CLI Sync Reference (beta)
+sidebar_label: Sync Reference
+slug: /cli-sync
+---
+
+This article contains a reference guide to the CLI sync commands found in
+`openfn project`, available since CLI XXX and undoing active development
+
+`openfn project` is a new command (and set of subcommands) designed to help run
+and build projects from the OpenFn app locally on your computer.
+
+You can use `openfn project` to:
+
+- Download projects run Lightning
+-
+
+Downloaded projects are fully compatible with the CLI
+
+::: tip
+
+The new `openfn project pull` nd `openfn project deploy` commands are
+replacements for `openfn pull` and `openfn deploy`. You can use the new command
+through `openfn pull --beta` and `openfn deploy --beta`.
+
+:::
+
+- explain file structure on pull
+- this is a terse reference and cheatsheet
+
+## Environments
+
+By default, when syncing to an app, the CLI will call app.openfn.org. If using
+another deployment, or local, you'll have to set this value
+
+Set env vars:
+
+```
+OPENFN_API_KEY=<key from app>
+OPENFN_ENDPOINT=https://app.staging.openfn.org
+```
+
+A `.env` file at the project root will be automatically loaded by the CLI. Check
+debug output for details.
+
+## Folder structure
+
+After pulling a project, it may look like this:
+
+```
+├── openfn.yaml
+├── .projects
+│   ├── main@app.staging.openfn.org.yaml
+│   └── test@app.staging.openfn.org.yaml
+└── workflows
+    ├── my-workflow
+    │   ├── my-workflow.yaml
+    │   ├── job.js
+```
+
+We call this file system a Workspace (not a project, because technically it
+holds multiple projects)
+
+At any time, one project can be "checked out" or "expanded". That means the the
+contents of the `workflows` folder represents that specific project. You cannot
+checkout two versions of the same workflow at once.
+
+- `openfn.yaml` contains settings and metadata about the checked out project
+- `.projects` contains a yaml file for each project. This is a local copy of a
+  remote project. It should always reflect an app's view of a project. You
+  should generally not edit these files.
+- `workflows` contains all the workflows for the checked out project. These are
+  compatible with the CLI.
+
+## Downloading a Project
+
+Pull (fetch + checkout) a project:
+
+```
+openfn project pull <uuid|uuid>
+```
+
+Pull with custom alias:
+
+```
+openfn project pull <uuid> --alias staging
+```
+
+Pull to custom path:
+
+```
+openfn project pull <alias|uuid> -o path/to/output
+```
+
+Force overwrite:
+
+```
+openfn project pull <alias|uuid> --force
+```
+
+Fetch without checkout:
+
+```
+openfn project fetch <alias|uuid>
+```
+
+Fetch to custom file:
+
+```
+openfn project fetch <alias> -o path/to/file.yaml
+```
+
+## Switching Projects
+
+Checkout a different project:
+
+```
+openfn project checkout <alias>
+```
+
+Checkout from file path:
+
+```
+openfn project checkout path/to/project.yaml
+```
+
+## Merging Projects
+
+Merge a project into the checked-out project:
+
+```
+openfn project merge <alias>
+```
+
+Merge and remove unmapped workflows:
+
+```
+openfn project merge <alias> --remove-unmapped
+```
+
+Merge to custom output:
+
+```
+openfn project merge <alias> -o path/to/output.yaml
+```
+
+Merge with custom base/target:
+
+```
+openfn project merge <alias> --base path/to/target.yaml
+```
+
+Force merge incompatible workflows:
+
+```
+openfn project merge <alias> --force
+```
+
+## Running a Project
+
+## Sandboxes
+
+## Other Commands
+
+List all projects in workspace:
+
+```
+openfn project list
+```
+
+## Workspace Options
+
+From any project command, set the working dir or path to the workspace. This
+should point to a folder with an openfn.yaml
+
+```
+openfn project fetch staging -w /path/to/workspace
+```
+
+You can also use an environment variable to pin this, if you're using a monorepo
+style:
+
+```
+OPENFN_WORKSPACE=/path/to/workspace
+```
