 Tool to extract Let's Encrypt certificates from Traefik's ACME storage file. Can automatically restart containers using the docker API.
 
 ## Installation
-```shell
+```
 git clone https://github.com/snowmb/traefik-certificate-extractor
 cd traefik-certificate-extractor
 ```
 
 ## Usage
-```shell
-usage: extractor.py [-h] [-c CERTIFICATE] [-d DIRECTORY] [-f] [-r] [--dry-run]
-                    [--include [INCLUDE [INCLUDE ...]] | --exclude

-Extract traefik letsencrypt certificates.

-optional arguments:
-  -h, --help            show this help message and exit
-  -c CERTIFICATE, --certificate CERTIFICATE
-                        file that contains the traefik certificates (default

-  --dry-run             Don't write files and do not start docker containers.

+python3 extractor.py [FILE]
 ```
 Default file is `./data/acme.json`. The output directories are `./certs` and `./certs_flat`.
 
 ## Docker
 There is a Docker image available for this tool: [snowmb/traefik-certificate-extractor](https://hub.docker.com/r/snowmb/traefik-certificate-extractor/).
 Example run:
-```shell
+```
 docker run --name extractor -d \
   -v /opt/traefik:/app/data \
   -v ./certs:/app/certs \
-  -v /var/run/docker.socket:/var/run/docker.sock \
-  snowmb/traefik-certificate-extractor -r
+  -v /var/run/docker.socket:/var/run/docker.socket \
+  snowmb/traefik-certificate-extractor
 ```
-Mount the whole folder containing the traefik certificate file (`acme.json`) as `/app/data`. The extracted certificates are going to be written to `/app/certs`.
+Mount the whole folder containing the traefik certificate file as `/app/data`. The extracted certificates are going to be written to `/app/certs`.
 The docker socket is used to find any containers with this label: `com.github.SnowMB.traefik-certificate-extractor.restart_domain=<DOMAIN>`.
 If the domains of an extracted certificate and the restart domain matches, the container is restarted. Multiple domains can be given seperated by `,`.
 
-You can easily use `docker-compose` to integrate this container into your setup:
-
-```yaml
-...
-services:
-  certs:
-     image: snowmb/traefik-certificate-extractor
-     volumes:
-      - path/to/acme.json:/app/data/acme.json:ro
-      - certs:/app/certs:rw
-      - /var/run/docker.sock:/var/run/docker.sock
-     command: -r --include example.com
-     restart: always
-```
