 ## Page structure
 
-Although this specification is about the interface that clients must provide, it is also worth noting that pages are written in standard [CommonMark](https://commonmark.org/), with the exception of the non-standard `{{` and `}}` placeholder syntax, which surrounds values in an example that users may edit. Clients MAY highlight the placeholders and MUST remove the surrounding curly braces. Clients MUST NOT treat them as the placeholder syntax if they are escaped using `\` (i.e. `\{\{` and `\}\}`) and MUST instead display literal braces, without backslashes. Placeholder escaping applies only when both braces are escaped (e.g. in `\{` or `\{{`, backslashes MUST be displayed). Clients MUST NOT break if the page format is changed within the _CommonMark_ specification.

Placeholder escaping applies only when both braces are escaped (e.g. in `\{` or `\{{`, backslashes MUST be displayed). In cases when a command uses `{}` in its arguments (e.g. `stash@{0}`) ***the outer braces*** mark the placeholder - the braces inside MUST be displayed. Clients MUST NOT break if the page format is changed within the _CommonMark_ specification.
 
 ### Examples
 
 - `ping {{example.com}}` MUST be rendered as "ping example.com"
 - `docker inspect --format '\{\{range.NetworkSettings.Networks\}\}\{\{.IPAddress\}\}\{\{end\}\}' {{container}}` MUST be rendered as "docker inspect --format '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container"
 - `mount \\{{computer_name}}\{{share_name}} Z:` MUST be rendered as "mount \\\\computer_name\share_name Z:"
+- `git stash show --patch {{stash@{0}}}` MUST be rendered as "git stash show --patch stash@{0}"

 Caching SHOULD be done according to the user's language configuration (if any), to not waste unneeded space for unused languages. Additionally, clients MAY automatically update the cache regularly.
