-## Features

-### Types to be generated
+### Types
 
 `filtgen` generates the following defined-types.  
+
+- `XxxSlice`(`[]T`)
+
+- `XxxMap[K]`(`map[K compareble]T`)
+
+- `XxxSeq[T]`(`iter.Seq[T]`)
+
+- `XxxSeq2[T]`(`iter.Seq2[T, U]`)
+
 Type name is determined by the struct name; e.g. `User` -> `UserSlice`.  
+
 To use the generated methods, cast must be performed.
