# Installation

LNbits uses [Pipenv][pipenv] to manage Python packages.

```sh
git clone https://github.com/lnbits/lnbits-legend.git
cd lnbits-legend/
pipenv shell
# pipenv --python 3.8 shell (if you wish to use a version of Python higher than 3.7)
pipenv install --dev
# pipenv --python 3.8 install --dev (if you wish to use a version of Python higher than 3.7)

# If any of the modules fails to install, try checking and upgrading your setupTool module
# pip install -U setuptools
``` 
## Running the server

LNbits uses [FastAPI][fastapi] as an application server.
Before running the server for the first time, make sure to create the data folder and edit the .env file:

    mkdir data
    cp .env.example .env
    sudo nano .env

To then run the server, use:

    pipenv run python -m uvicorn lnbits.__main__:app --reload

You might also need to install additional packages, depending on the [backend wallet](../guide/wallets.md) you use.
E.g. when you want to use LND you have to `pipenv run pip install lndgrpc` and `pipenv run pip install purerpc`.

Take a look at [Polar][polar] for an excellent way of spinning up a Lightning Network dev environment.

**Note**: We reccomend using <a href="https://caddyserver.com/docs/install#debian-ubuntu-raspbian">Caddy</a> for a reverse-proxy, if you want to serve your install through a domain, alternatively you can use [ngrok](https://ngrok.com/).
