-#### Triggers
+### Triggers
 Triggers allow to perform conditional actions, like visual/sound alerts or an arbitrary shell command.
 
-#### Interactive shell support
+### Interactive shell support
 In addition to the `sample` command, one can specify `init` command (executed only once before sampling) and `transform` command (to post-process `sample` command output). That covers interactive shell use case, e.g. to establish connection to a database only once, and then perform polling within interactive shell session. MongoDB example: ...
 
-#### Variables
+### Variables
 If the configuration file contains repeated patterns, they can be extracted into the `variables` section.
 Also variables can be specified using `-v`/`--variable` flag on startup, and any system environment variables will also be available in the scripts.
