 # Arguments
 - `languages::Vector{String}`: A list of languages to be used for language detection. If this argument is not provided, all the languages returned by the [`supported_languages`](@ref) function will be used.
-- `ngram::Union{Int, AbstractVector}`: The length of utf-8 byte n-grams to use for language detection. A range can be provided to use multiple n-gram sizes. An integer value will be converted to a range from 1 to the given value. The default value is 4.
+- `ngram::Union{Int, AbstractVector}`: Specifies the length of UTF-8 byte n-grams to be utilized for language detection. An integer value can be provided to use a single n-gram size, while a range can be provided to use multiple n-gram sizes. The default value is 1:4, and the maximum value allowed is 7.
 - `cutoff::Float64`: The cutoff value of the cumulative probability of the n-grams to use for language detection. The default value is 0.85, and it must be between 0 and 1.
 - `vocabulary::Union{Int, AbstractRange}`: The size range of the vocabulary of each language. The default value is 1000:5000.
