## Setup

You can download the source code with:

```

git clone --recursive https://github.com/Smithsonian/layup.git

```

If you cloned the repository without `--recursive` flag, you can run

```

git submodule update --init

```

to download the required submodules, `assist`, `eigen`, and `rebound`.

Next, run

```

pip install -e .

```

to create an editable install of `layup`. If you're doing development work, you can install with

```

pip install -e ".[dev]"

```

to install all of the development packages as well.

### Linux

If you're running `layup` on a linux distribution, you should add the `layup` root directory to your`$LD_LIBRARY_PATH`, with something like

```

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:

```

so that python's dynamic linker can find the `assist` and `rebound` library objects at runtime.

### Adding new submodule 

Note that to get the new submodules added in an existing copy of the repo you want to run

```

git submodule update --init

```

And in subsequent clones of the repo you want to run

```

git clone --recursive https://github.com/Smithsonian/layup.git

```
