-
-## Discussion
-
-Please provide feedback on:
-
-* API changes: extend visitor with return values (https://github.com/JSQLParser/JSqlParser/issues/901)
-
-## News
-* Released version **4.5** of JSqlParser
-* The array parsing is the default behaviour. Square bracket quotation has to be enabled using 
-  a parser flag (**CCJSqlParser.withSquareBracketQuotation**).
-* due to an API change the version will be 3.0
-* JSqlParser uses now Java 8 at the minimum
-
-More news can be found here: https://github.com/JSQLParser/JSqlParser/wiki/News.
-
-## Alternatives to JSqlParser?
-[**General SQL Parser**](http://www.sqlparser.com/features/introduce.php?utm_source=github-jsqlparser&utm_medium=text-general) looks pretty good, with extended SQL syntax (like PL/SQL and T-SQL) and java + .NET APIs. The tool is commercial (license available online), with a free download option.
-
-## JSqlParser
-
-JSqlParser is a SQL statement parser. It translates SQLs in a traversable hierarchy of Java classes. JSqlParser is not limited to one database but provides support for a lot of specials of Oracle, SqlServer, MySQL, PostgreSQL ... To name some, it has support for Oracles join syntax using (+), PostgreSQLs cast syntax using ::, relational operators like != and so on.
-
-## Support
-If you need help using JSqlParser feel free to file an issue or contact me.
-
-## Contributions
-To help JSqlParser's development you are encouraged to provide 
-* feedback
-* bugreports
-* pull requests for new features
-* improvement requests
-* fund new features or sponsor JSqlParser ([**Sponsor**](https://www.paypal.me/wumpz))
-
-**Please write in English, since it's the language most of the dev team knows.**
+## Summary
 
-Any requests for examples or any particular documentation will be most welcome.
+Please visit the [WebSite](https://jsqlparser.github.io/JSqlParser). **JSqlParser** is a RDBMS agnostic SQL statement parser. It translates SQL statements into a traversable hierarchy of Java classes (see [Samples](https://jsqlparser.github.io/JSqlParser/usage.html#parse-a-sql-statements)):
 
-## Extensions in the latest SNAPSHOT version 4.6
-
-* support for named windows in window expressions: `SELECT sum(c) OVER winName FROM mytable WINDOW winName AS (PARTITION BY pcol)`
+```sql
+SELECT 1 FROM dual WHERE a = b
+```
 
-Additionally, we have fixed many errors and improved the code quality and the test coverage.
+```text
+ SQL Text
+  └─Statements: net.sf.jsqlparser.statement.select.Select
+     └─selectBody: net.sf.jsqlparser.statement.select.PlainSelect
+        ├─selectItems -> Collection<SelectExpressionItem>
+        │  └─selectItems: net.sf.jsqlparser.statement.select.SelectExpressionItem
+        │     └─LongValue: 1
+        ├─Table: dual
+        └─where: net.sf.jsqlparser.expression.operators.relational.EqualsTo
+           ├─Column: a
+           └─Column: b
+```
 
-## Extensions of JSqlParser releases
+```java
+Statement statement = CCJSqlParserUtil.parse(sqlStr);
+if (statement instanceof Select) {
+    Select select = (Select) statement;
+    PlainSelect plainSelect = (PlainSelect) select.getSelectBody();
 
-* [Release Notes](https://github.com/JSQLParser/JSqlParser/releases)
-* Modifications before GitHub's release tagging are listed in the [Older Releases](https://github.com/JSQLParser/JSqlParser/wiki/Older-Releases) page.
+    SelectExpressionItem selectExpressionItem =
+            (SelectExpressionItem) plainSelect.getSelectItems().get(0);
 
-## Building from the sources
+    Table table = (Table) plainSelect.getFromItem();
 
-As the project is a Maven project, building is rather simple by running:
-```shell
-mvn package
+    EqualsTo equalsTo = (EqualsTo) plainSelect.getWhere();
+    Column a = (Column) equalsTo.getLeftExpression();
+    Column b = (Column) equalsTo.getRightExpression();
+}
 ```
 
-Since 4.2, alternatively Gradle can be used
-```shell
-gradle build
-```
-
-The project requires the following to build:
-- Maven (or Gradle)
-- JDK 8 or later. The JAR will target JDK 8, but the version of the maven-compiler-plugin that JSqlParser uses requires JDK 8+
+## [Supported Grammar and Syntax](https://jsqlparser.github.io/JSqlParser/syntax.html)
 
-This will produce the jsqlparser-VERSION.jar file in the `target/` directory (`build/libs/jsqlparser-VERSION.jar` in case of Gradle).
+**JSqlParser** aims to support the SQL standard as well as all major RDBMS. Any missing syntax or features can be added on demand.
 
-**To build this project without using Maven or Gradle, one has to build the parser by JavaCC using the CLI options it provides.**
+| RDBMS                              | Statements                              |
+|------------------------------------|-----------------------------------------|
+| Oracle<br>MS SQL Server and Sybase<br>PostgreSQL<br>MySQL and MariaDB<br>DB2<br>H2 and HSQLDB and Derby<br>SQLite| `SELECT`<br>`INSERT`, `UPDATE`, `UPSERT`, `MERGE`<br>`DELETE`, `TRUNCATE TABLE`<br>`CREATE ...`, `ALTER ....`, `DROP ...`<br>`WITH ...` |
 
-## Debugging through problems
 
-Refer to the [Visualize Parsing](https://github.com/JSQLParser/JSqlParser/wiki/Examples-of-SQL-parsing#visualize-parsing) section to learn how to run the parser in debug mode.
+**JSqlParser** can also be used to create SQL Statements from Java Code with a fluent API (see [Samples](https://jsqlparser.github.io/JSqlParser/usage.html#build-a-sql-statements)).
 
-## Source Code conventions
+## [Documentation](https://jsqlparser.github.io/JSqlParser)
 
-Recently a checkstyle process was integrated into the build process. JSqlParser follows the sun java format convention. There are no TABs allowed. Use spaces.
+### [Samples](https://jsqlparser.github.io/JSqlParser/usage.html#parse-a-sql-statements)
+### [Build Instructions](https://jsqlparser.github.io/JSqlParser/usage.html)
+### [Contribution](https://jsqlparser.github.io/JSqlParser/contribution.html)
+### [Change Log](https://jsqlparser.github.io/JSqlParser/changelog.html#latest-changes-since-jsqlparser-version)
+### [Issues](https://github.com/JSQLParser/JSqlParser/issues)
 
-```java
-public void setUsingSelect(SubSelect usingSelect) {
-    this.usingSelect = usingSelect;
-    if (this.usingSelect != null) {
-        this.usingSelect.setUseBrackets(false);
-    }
-}
-```
-
-This is a valid piece of source code:
-* blocks without braces are not allowed
-* after control statements (if, while, for) a whitespace is expected
-* the opening brace should be in the same line as the control statement
-
-## Maven Repository
-
-JSQLParser is deployed at Sonatype open source maven repository. 
-Starting from now I will deploy there. The first snapshot version there will be 0.8.5-SNAPSHOT.
-To use it this is the repository configuration:
-
-```xml
-<repositories>
-     <repository>
-         <id>jsqlparser-snapshots</id>
-         <snapshots>
-             <enabled>true</enabled>
-         </snapshots>
-         <url>https://oss.sonatype.org/content/groups/public/</url>
-     </repository>
-</repositories>
-```
-These repository releases will be synchronised to Maven Central. Snapshots remain at Sonatype.
-
-And this is the dependency declaration in your pom:
-```xml
-<dependency>
-	<groupId>com.github.jsqlparser</groupId>
-	<artifactId>jsqlparser</artifactId>
-	<version>4.5</version>
-</dependency>
-```
