+# acme
+
+[acme.sh](https://github.com/acmesh-official/acme.sh) shell-script ACME client
+for issuing LetsEncrypt certificates
+
+Has a chicken/egg problem if you haven't configured a webserver and are using
+the "http" method of obtaining certs - can't run the server without certs,
+can't issue certs without it being up. Best practice is to bootstrap a non-TLS
+server first, then run this role, then switch on TLS.
+
+## References
+
+Upstream [Options and
+Parameters](https://github.com/acmesh-official/acme.sh/wiki/Options-and-Params)
+
+## Requirements
+
+Minimum tested ansible version: 2.9.5
+
+## Defaults
+
+See `defaults/main.yml`
+
+By default no certificates are issued, you need to configure the `acme_certs`
+to specify which ones to obtain.
+
+## Example Playbook
+
+```yaml
+- hosts: all
+ vars:
+ acme_certs:
+ - cert_names:
+ - "static.example.com"
+ - "alias.example.com"
+ method: "http"
+ roles:
+ - acme
+
+```
