 # Quickstart
-If you're already familiar with Pandas, getting started will be a breeze! Below we provide a simple example program using the semantic join operator. The join, like many semantic operators, are specified by **langex** (natural language expressions), which the programmer uses to specify the operation. Each langex is paramterized by one or more table columns, denoted in brackets. The join's langex serves as a predicate and is parameterized by a right and left join key.
