See below for installation instructions

# 1. Pre-requisites

• [mamba](https://mamba.readthedocs.io/en/latest/installation.html): Follow the instructions for installing [Mambaforge](https://github.com/conda-forge/miniforge#mambaforge) - Last known working: mamba==0.27.0 and conda==22.9.0

• [GNU Make](https://www.gnu.org/software/make/): Version > 3.81 required. (Default version on macos is 3.81)

# 2. Create luna virtual environment and install packages

At the command line:

`shell make venv `

Activate the luna virtual environment:

`shell conda activate .venv/luna `

# 3. Setup LUNA_HOME and Configurations

LUNA_HOME is an environment variable that points to a location where luna configs will be stored.

1. Set $LUNA_HOME as the current directory:

   `shell export LUNA_HOME=<path/to/your/workspace> `

2. Prepare configuration files and place them at $LUNA_HOME/conf Example configurations files are at [Luna repo](https://github.com/msk-mind/luna/tree/dev/conf)

Currently, we have two configuration files.

• datastore.cfg: configuration for the backend store of your data. POSIX and Minio backends are supported.

• logging.cfg: configuration for logging level and optional central logging in MongoDB.
