You can create plain (empty) programs, without either Mbed OS 5 or Mbed OS 2, by using the `--create-only` option.

### Managing multiple Mbed projects

You can create multiple Mbed projects and use the same Mbed OS library directory for each of these projects with the following commands:

```
$ cd <projects directory>
$ mbed import mbed-os
$ mbed config -G MBED_OS_DIR <projects directory>/mbed-os
[mbed] <projects directory>/mbed-os now set as global MBED_OS_DIR
$ mbed new project1
[mbed] Creating new program "project1" (git)
$ mbed new project2
[mbed] Creating new program "project2" (git)
```

Add your `main.cpp` file and other project files to the `project1` and `project2` directories. Then compile each project from the root `<projects directory>` with the following example commands:

```
$ mbed compile -t ARM -m LPC1768 --source project1 --source mbed-os --build BUILD/project1
$ mbed compile -t ARM -m K64F --source project2 --source mbed-os --build BUILD/project2
```

### Importing an existing program

Use `mbed import` to clone an existing program and all its dependencies to your machine:
