-# PostgreSQL
+# PostgreSQL (13–18)
 
-## From their [Website](https://www.postgresql.org/)
+## Overview
 
-The World's Most Advanced Open Source Relational Database
+This egg provides a PostgreSQL server with support for multiple versions (13 through 18) within a single configuration.
 
-## Minimum RAM warning
+Originally based on the default Pterodactyl setup, it has been manually extended to allow version selection and basic upgrade handling. Because of these modifications, behavior may differ from standard eggs.
 
-2 Gigabytes minimum recommended
+For official documentation, visit the PostgreSQL Global Development Group website: [https://www.postgresql.org/](https://www.postgresql.org/)
 
-See here <https://www.commandprompt.com/blog/postgresql_mininum_requirements/>

+
+## Important Notes
+
+1. This egg supports switching between PostgreSQL versions 13–18
+2. Changing the version after installation may trigger a data migration or upgrade process
+3. Upgrades are best-effort and may require manual intervention depending on environment compatibility
+4. Always ensure backups exist before changing versions
+
+---
+
+## Minimum Requirements
+
+At least 2 GB of RAM is recommended for stable operation.
+
