 ### Manual generation
 
 If you prefer to generate the client explicitly rather than automatically, you can use `calibanGenClient` on the SBT CLI as follows:
 
 ```bash
-calibanGenClient schemaPath outputPath [--scalafmtPath path] [--headers name:value,name2:value2] [--genView true|false] [--scalarMappings gqlType:f.q.d.n.Type,gqlType2:f.q.d.n.Type2] [--imports a.b.c._,c.d.E] [--splitFiles true|false] [--enableFmt true|false]
