+## Introduction
+
+**CRUD Java** is a Java-based application that provides a platform to interact with various database systems, both SQL and NoSQL. It allows users to perform Create, Read, Update, and Delete (CRUD) operations across different database types through a unified interface.
+
+## Features
+
+- **Multi-Database Support**: Connect to and manage HyperSQL, PostgreSQL, MariaDB, MySQL, SQLite, and MongoDB databases.
+- **User Authentication**: Login interfaces tailored for each database type.
+- **Table and Collection Management**: Create or delete tables (SQL) and collections (MongoDB) using schemas or manual input.
+- **Data Manipulation**: Add, edit, and delete entries, with special considerations for primary keys in SQL databases.
+- **Custom Console**: Integrated console for SQL databases with command history, placeholders, and synchronized table views.
+- **Pagination and View Control**: Adjust the number of entries per page and navigate through data.
+- **Mass Actions**: Perform bulk operations in MongoDB based on specific conditions.
+- **Adjustable Interface**: Resize console and input areas, with keyboard shortcuts for enhanced productivity.
+
+## Supported Databases
+
+- **SQL Databases**:
+    - HyperSQL
+    - PostgreSQL
+    - MariaDB
+    - MySQL
+    - SQLite
+- **NoSQL Database**:
+    - MongoDB
+
+## Getting Started
+
+### Login Screen
+
+Upon launching the application, you are presented with a selection screen to choose the type of database to connect to. Each database type has its own login interface to capture all necessary connection parameters.
+
+- **Database Selection**: Choose from the supported databases.
+- **Credentials Input**: Enter information such as hostname, port, username, and password.
+- **Database-Specific Options**: Some databases may require additional settings provided in the login interface.

+
+## Using the Application
+
+The interface varies depending on whether you are working with an SQL database or MongoDB.
+
+### SQL Databases
+
+#### Table Management
+
+After logging in, you will see a list of existing tables in the connected database.
+
+- **Create New Tables**:
+    - **Using a Schema**: Import a predefined schema to create a table.
+    - **Manual Creation**: Input the table name, define field names, and specify data types.
+- **Delete Existing Tables**: Select a table and choose to delete it, with confirmation to prevent accidental deletions.

+
+#### Data Manipulation
+
+After selecting a table, you can view and manipulate its data:
+
+- **Add New Fields**: Add new columns to the table.
+- **View Entries**:
+    - Adjust the number of entries displayed per page.
+    - Navigate between pages.
+- **Edit Entries**:
+    - Modify field values directly in the table view.
+    - **Note**: Primary key fields are not editable.
+- **Delete Entries**: Select entries to remove them.
+
+#### Custom Console
+
+At the bottom of the SQL database interface is a custom console:
+
+- **Command Execution**: Enter SQL commands.
+- **Command History**: Use up (`↑`) and down (`↓`) arrow keys to navigate through previous commands.
+- **Placeholders**:
+    - Use `{}` as a placeholder for the selected table name.
+- **Dynamic Updates**:
+    - Executing queries updates the console output and the table view.
+- **Adjustable Size**:
+    - Resize the console and command input area.
+- **Line Breaks**:
+    - Use `ALT+ENTER` to insert a line break.

+
+### MongoDB
+
+#### Data Manipulation
+
+- **Viewing Collections**: All collections are listed upon login.
+- **Unified Field Display**:
+    - The data grid shows all fields present across documents.
+    - Empty cells represent fields not present in a document.
+    - `'-'` indicates fields that exist but have empty values.
+- **Adding Entries**:
+    - Insert new documents.
+    - **Field Management**:
+        - Create new fields as needed.
+        - Load field models from existing documents.
+- **Editing Entries**: Modify any field directly in the data grid.
+- **Removing Entries**: Select documents to delete them.
+
+#### Mass Actions
+
+The Mass Action feature allows bulk operations:
+
+- **Add Multiple Entries**: Insert several documents at once.
+- **Add/Remove Fields**: Modify multiple documents' structure.
+- **Conditional Operations**: Apply actions based on conditions.
+- **Batch Deletions**: Remove documents that meet specified conditions.

+
+## Notes
+
+- Modifying the primary key of an SQL table entry is restricted to maintain data integrity.
+- In the custom console, `{}` can be used as a placeholder for the current table name. For example, `SELECT * FROM {}`.
+- To insert a line break in the console, press `ALT+ENTER` while typing your command.
