-# Databasir
+# Databasir
+
+Database document generator
+
+you could use `databasir` to generate database meta model, or render it as markdown / pdf (TODO) / html (TODO)
+
+# How to use
+
+## Database Meta to Java Model
+
+```java
+java.sql.Connection connection = ...;
+DatabaseDocConfig config = DatabaseDocConfig.builder()
+        .databaseName("Demo")
+        .connection(connection)
+        .build();
+DatabaseDoc doc = JdbcDatabaseDocFactory.of().create(config).orElseThrow();
+```
+
+## Render as Markdown
+```java
+java.sql.Connection connection = ...;
+DatabaseDocConfig config = DatabaseDocConfig.builder()
+        .databaseName("Demo")
+        .connection(connection)
+        .build();
+DatabaseDoc doc = JdbcDatabaseDocFactory.of().create(config).orElseThrow();
+try (FileOutputStream out = new FileOutputStream("doc.md")) {
+    RenderConfig renderConfig = new RenderConfig();
+    Render.markdownRender(renderConfig).rendering(doc, out);
+} catch (IOException e) {
+    throw new IllegalStateException(e);
+}
+```
+
+- Example
+
+![](README/table-doc.png)
+
+
+## Ignore tables or columns
+
+support regex pattern to ignore table or column
+
+```java
+java.sql.Connection connection = ...;
+DatabaseDocConfig config = DatabaseDocConfig.builder()
+        .databaseName("Demo")
+        .connection(connection)
+        .ignoreTableRegexes(Arrays.asList("mysql_*"))
+        .ignoreColumnRegexes(Arrays.asList("id"))
+        .build();
+DatabaseDoc doc = JdbcDatabaseDocFactory.of().create(config).orElseThrow();
+```
+
+## Extension
+
+Default factory
+
+- tableDocFactory ->  `com.databasir.core.doc.factory.jdbc.JdbcTableDocFactory`
+- columnDocFactory -> `com.databasir.core.doc.factory.jdbc.JdbcTableColumnDocFactory`
+- indexDocFactory -> `com.databasir.core.doc.factory.jdbc.JdbcTableIndexDocFactory`
+- triggerDocFactory -> `com.databasir.core.doc.factory.jdbc.JdbcTableTriggerDocFactory`
+
+Custom configuration
+```java
+java.sql.Connection connection = ...;
+DatabaseDocConfig config = DatabaseDocConfig.builder()
+        .databaseName("Demo")
+        .connection(connection)
+        .tableDocFactory(...) // your custom table doc factory
