 - **browse** enables file listings for requests to directories that do not have an index file.
 - **root** sets the path to the site root for just this file server instance, overriding any other. Default: `{http.vars.root}` or the current working directory. Note: This subdirective only changes the root for this directive. For other directives (like [`try_files`](/docs/caddyfile/directives/try_files) or [`templates`](/docs/caddyfile/directives/templates)) to know the same site root, use the [`root`](/docs/caddyfile/directives/root) directive, not this subdirective.

+- **hide** is a list of files or folders to hide; if requested, the file server will pretend they do not exist. Accepts placeholders and glob patterns. Note that these are _file system_ paths, NOT request paths. In other words, relative paths use the current working directory as a base, NOT the site root; and all paths are transformed to their absolute form before comparisons (if possible). Specifying a file name or pattern without a path separator will hide all files with a matching name regardless of its location; otherwise, a path prefix match will be attempted, and then a globular match. Since this is a Caddyfile config, the active configuration file(s) will be added by default.
 - **index** is a list of filenames to look for as index files. Default: `index.html index.txt`
 - **<template_file>** is an optional custom template file to use for directory listings.

-The config for `zerossl` is exactly the same as the config for `acme`, except that its name is `zerossl`, it will use ZeroSSL's directory, and it will automatically negotiate EAB credentials. In other words, simply specifying this issuer (with no other configuration) is enough to use ZeroSSL.

+The syntax for `zerossl` is exactly the same as for `acme`, except that its name is `zerossl` and it can optionally take your ZeroSSL API key.
 
-Note that ZeroSSL is RFC-8555-compliant and can be used with the `acme` issuer module instead, but this module is more convenient because it handles the EAB credentials under the hood for you.
+The functionality of the `zerossl` issuer is the same as the `acme` issuer, except that it will use ZeroSSL's directory by default and it can automatically negotiate EAB credentials (whereas with the `acme` issuer, you have to manually provide EAB credentials and set the directory endpoint).
 
+When explicitly configuring `zerossl`, an email address is required so that your certificates can appear in your ZeroSSL dashboard.

+Note that ZeroSSL is a default issuer, so configuring it explicitly is usually unnecessary.
