 ### ⚡️ Compile-/Typesafe SQL queries via WHERE class
 ### ⚡️ Various utility methods, like fetching results lazily
 
-#### Pros

-##### Safety
+### Safety
 - Secured against SQL-Injection by using prepared statements.
 - Protection against timed out connections.
 - 0% boilerplate and simple code decreasing the risk for bugs.
 - (Optional) Helper WHERE class for generating simple and complex SQL queries, from compile-safe functions.
 
-##### Performance
+### Performance
 - No runtime overhead for class generation (unlike other ORMs).
 - Cached connection pool ensures optimal performance on small and huge databases.
   Besides that it provides protection against timed out connections.

-##### Customization
+### Customization
 - Generated classes can be enhanced by adding your own custom code at the top of the class.
 - Name your tables/columns however you like since internally names are encapsulated in backticks.
 
-##### SQL & JDBC
+### SQL & JDBC
 - The generated SQL code should be compatible with all types of SQL databases.
 - Supports all JDBC data types + some extras like enum. ![img.png](img.png)
 - `NULL` is not allowed, instead use the `DEFAULT ''` keyword.
 - Supports DEFAULT for blobs. Example: `file BLOB DEFAULT ''`.
 - Supports SQL DEFAULT for `NOW(), CURDATE(), CURTIME()`.
 
-##### Other
+### Other
 - Simple UI to design databases within minutes.
 - Database structure/design as JSON file.
 - Autosuggestions for field definitions.

 - The generated Java code does not require any third party libraries and should work with Java 8 or higher. It uses the built in JDBC API for SQL queries.
 - (Optional) Supports generating Vaadin Flow Form to create/update/delete each object/row.
 
-#### Cons
+### Cons
 - Updating existing tables is a bit rough (removed fields/columns must be also removed manually from the database, especially "not null fields").
 A fix for this is being worked on: https://github.com/Osiris-Team/jSQL-Gen/issues/7
 - You need to know a bit of SQL, especially about definitions and defaults. This could be fixed by simplifying the GUI further.
+- Internally a `idCounter` is used for each table, meaning if rows are added by another program the counter won't be accurate anymore and thus further insert operations will fail.
 
 ## Tipps
 - You can select a project directory to directly generate the code in there. The generated code/files can also be found in the `generated` folder (press `Show Data` on the first tab, to open the location).
