+# Oracle Transaction Manager for Microservices (MicroTX)
+In microservices architectures, ensuring data consistency across distributed services can be challenging due to the lack of built-in transaction management. The "Dual Write" problem, where data updates must be written to multiple services or databases, often leads to inconsistencies. Tools like MicroTX are essential for managing these distributed transactions, maintaining data integrity, and simplifying development.
 
+Oracle Transaction Manager for Microservices (**MicroTX or OTMM**) is a powerful tool designed to manage distributed transactions in a microservices architecture. It simplifies the microservices architecture and development, ensuring data consistency across multiple microservices without any additional code for compensation. MicroTx supports not only Oracle databases but also multiple datasource types, providing flexibility for various application requirements.
 
+MicroTx supports various transaction models; the Saga pattern, Try Confirm/Cancel (TCC) pattern and two-phase commit (2PC), providing flexibility for different application requirements. It enables seamless integration and coordination of complex business processes across diverse microservices environments.
+
+MicroTx is available in two editions:
+  - **Oracle Transaction Manager for Microservices Free**: The Free version of MicroTx provides access to core transaction management features with a limitation of **100 transactions per minute**. This version is ideal for small-scale applications or for developers looking to explore OTMM capabilities without incurring costs.
+  - **Oracle Transaction Manager for Microservices Enterprise**: The Enterprise version of MicroTx offers unlimited transactions per minute and includes advanced features, enhanced performance, and dedicated support. It is designed for large-scale, mission-critical applications requiring robust transaction management across multiple microservices.
+
+Additionally, MicroTx provides libraries for the most popular development languages and frameworks, making it easy for developers to integrate and use MicroTx in their existing projects.
+
