 ## `bf dialog:merge PATTERNS`
 
-Merge `<kind>.schema` and `<kind>[.<locale>].uischema` definitions from a project and its dependencies into a single .schema for describing .dialog files and a per locale .uischema for describing how Composer shows them.  If a dependent package has an "exported" directory it is copied to /<package> in the --imports directory.
+Merge `<kind>.schema` and `<kind>[.<locale>].uischema` definitions from a project and its dependencies into a single .schema for describing .dialog files and a per locale .uischema for describing how Composer shows them.  If a dependent package has an "exported" directory it is copied to /<package> in the --imports directory. You can make use of negative patterns like !**/generated/** to exclude particular directories or files, although some directories like bin, obj and node_modules are automatically excluded.
