+=========================================
 
 In the following, there is the list of supported template fields
-('<identifier>': description), that can be used to define new template
+``('<identifier>': description)``, that can be used to define new template
 descriptors by adding their identifier to the format string
 (support for more data types will be added later):

-        calculated with the SHA1 or MD5 hash algorithm;

  - 'n': the name of the event (i.e. the file name), with size up to 255 bytes;
  - 'd-ng': the digest of the event, calculated with an arbitrary hash
-           algorithm (field format: [<hash algo>:]digest, where the digest
-           prefix is shown only if the hash algorithm is not SHA1 or MD5);
+   algorithm (field format: [<hash algo>:]digest, where the digest
+   prefix is shown only if the hash algorithm is not SHA1 or MD5);
  - 'n-ng': the name of the event, without size limitations;
  - 'sig': the file signature.
 
 
 Below, there is the list of defined template descriptors:
- - "ima": its format is 'd|n';
- - "ima-ng" (default): its format is 'd-ng|n-ng';
- - "ima-sig": its format is 'd-ng|n-ng|sig'.

 To specify the template descriptor to be used to generate measurement entries,
 currently the following methods are supported:
 
  - select a template descriptor among those supported in the kernel
-   configuration ('ima-ng' is the default choice);
+   configuration (``ima-ng`` is the default choice);
  - specify a template descriptor name from the kernel command line through
-   the 'ima_template=' parameter;
+   the ``ima_template=`` parameter;
  - register a new template descriptor with custom format through the kernel
-   command line parameter 'ima_template_fmt='.
+   command line parameter ``ima_template_fmt=``.
