# You can defines:
#   - Intents
#   - Entities (with or without variants)
#   - Synonyms
#   - Comments (only at the top level)

# Inside an intent, you got training data.
# Training data can refer to one or more entities and/or synonyms, they will be used
# by generators to generate all possible permutations and training samples.

~[greet]
  hi
  hello

# Entities contains available samples and could refer to a synonym.
