## Install
### Docker
### Ansible (recommended)
Make sure you have both docker and docker-compose(>=`1.24.0`) installed.
First, you need to [install Ansible on your local computer](https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html),
eg using `sudo apt install ansible`, or the equivalent for you platform.
Then run the following commands on your local computer:
```bash
git clone https://github.com/dessalines/lemmy.git
cd lemmy/ansible/
cp inventory.example inventory
nano inventory # enter your server, domain, contact email
ansible-playbook lemmy.yml
```
### Manual
Make sure you have both docker and docker-compose installed.
```
mkdir lemmy/
cd lemmy/
wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/prod/docker-compose.yml
wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/prod/env -O .env
wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/prod/nginx.conf
# you need to edit .env and nginx.conf to replace the indicated {{ variables }}
sudo mv nginx.conf /etc/nginx/sites-enabled/lemmy.conf
docker-compose up -d
```
