+# Trino grammar for ANTLR4
+
+An ANTLR4 grammar for Trino, formerly known as PrestoSQL.
+This grammar is based on the actively maintained [Trino repository](https://github.com/trinodb/trino).
+
+The lexer and parser are referenced from the [offical base antlr file](https://github.com/trinodb/trino/blob/master/core/trino-parser/src/main/antlr4/io/trino/sql/parser/SqlBase.g4).
+Changes are made to accommodate various language targets as the official one is being developed for Java only.
+
+The examples are extracted from the [offical test file](https://github.com/trinodb/trino/blob/master/core/trino-parser/src/test/java/io/trino/sql/parser/TestSqlParser.java).
