+## Install
+
+### With Docker
+
+A Docker [image](https://github.com/users/thomiceli/packages/container/package/opengist), available for each release, can be pulled
+
+```
+docker pull ghcr.io/thomiceli/opengist:1
+```
+
+It can be used in a `docker-compose.yml` file :
+
+1. Create a `docker-compose.yml` file with the following content
+2. Run `docker-compose up -d`
+3. Opengist is now running on port 6157, you can browse http://localhost:6157
+
+```yml
+version: "3"
+
+services:
+  opengist:
+    image: ghcr.io/thomiceli/opengist:1
+    container_name: opengist
+    restart: unless-stopped
+    ports:
+      - "6157:6157" # HTTP port
+      - "2222:2222" # SSH port, can be removed if you don't use SSH
+    volumes:
+      - "$HOME/.opengist:/root/.opengist"
+    environment:
+      CONFIG: |
+        log-level: info
+```
+
+### From source
+
+Requirements : [Git](https://git-scm.com/downloads) (2.20+), [Go](https://go.dev/doc/install) (1.19+), [Node.js](https://nodejs.org/en/download/) (16+)
+
+```shell
+git clone https://github.com/thomiceli/opengist
+cd opengist
+make
+./opengist
+```
+
+Opengist is now running on port 6157, you can browse http://localhost:6157
+
+## Configuration
+
+Opengist can be configured using YAML. The full configuration file is [config.yml](config.yml), each default key/value
+pair can be overridden.
+
+### With docker
+
+Add a `CONFIG` environment variable in the `docker-compose.yml` file to the `opengist` service :
+
+```diff
+environment:
+  CONFIG: |
+    log-level: info
+    ssh.git-enabled: false
+    disable-signup: true
+    # ...
+```
+
+### With binary
+
+Create a `config.yml` file (you can reuse this [one](config.yml)) and run Opengist binary with the `--config` flag :
+
+```shell
+./opengist --config /path/to/config.yml
+```
+
+
+## Administration
+
+### Use Nginx as a reverse proxy
+
+Configure Nginx to proxy requests to Opengist. Here is an example configuration file :
+```
+server {
+    listen 80;
+    server_name opengist.example.com;
+
+    location / {
+        proxy_pass http://127.0.0.1:6157;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+}
+```
+
+Then run :
+```shell
+service nginx restart 
+```
+
+### Use Fail2ban
+
+Fail2ban can be used to ban IPs that try to bruteforce the login page.
+Log level must be set at least to `warn`.
+
+Add this filter in `etc/fail2ban/filter.d/opengist.conf` :
+```ini
+[Definition]
+failregex =  Invalid .* authentication attempt from <HOST>
+ignoreregex =
+```
+
+Add this jail in `etc/fail2ban/jail.d/opengist.conf` :
+```ini
+[opengist]
+enabled = true
+filter = opengist
+logpath = /home/*/.opengist/log/opengist.log
+maxretry = 10
+findtime = 3600
+bantime = 600
+banaction = iptables-allports
+port = anyport
+```
+
+Then run
+```shell
+service fail2ban restart 
+```
