 The last (4th) element defines an optional ping url used for health reporting. I.e.`*,^/api/(.*),https://api.example.com/$1,https://api.example.com/ping`. See [Health check](#ping-and-health-checks) section for more details.
 
-_Pls note: in case if rules set as a part of docker compose environment, destination with the regex group will conflict with compose syntax. I.e. attempt to use `https://api.example.com/$1` in compose environment will fail due to a syntax error. The standard solution here is to "escape" `$` sign by replacing it with `$$`, i.e. `https://api.example.com/$$1`. This substitution supported by docker compose and has nothing to do with reproxy itself. Another way is to use `@` instead of `$` which is supported on reproxy level, i.e. `https://api.example.com/@1`_

 ## SSL support
 
 SSL mode (by default none) can be set to `auto` (ACME/LE certificates), `static` (existing certificate) or `none`. If `auto` turned on SSL certificate will be issued automatically for all discovered server names. User can override it by setting `--ssl.fqdn` value(s)
