 This script converts an alias file to a sieve script for [stalwart-mail](https://stalw.art/).
 
 ## Usage
-Given an alias file `testdata/simple.aliases` that contains lines of redirects of the form localpart with optional `@fqdn` followed by a space followed by a list (space or comma+space separated) list of destinations that consist of a localpart and optionally an `@fqdn`.
+Given an alias file [`testdata/example.aliases`](testdata/example.aliases) that contains lines of redirects of the form localpart with optional `@fqdn` followed by a space followed by a list (space or comma+space separated) list of destinations that consist of a localpart and optionally an `@fqdn`.
 If you don't define a fqdn along any of the addresses, the default domain from your commandline input will be appended.
 
 An example using the testdata directory of this repository:
-```bash
-$ ./alias_to_sieve testdata/simple.aliases example.com

 ## Limitations
 You cannot use apostrophes (') in any mail addresses although allowed by [RFC 5322](https://www.rfc-editor.org/rfc/rfc5322) since they would break termination of strings in sieve.
