+## App Writable Folder
+
+This directory is designated for:
+
+- **Embedded Databases**: Such as SQLite.
+- **Writable Files**: Files that the application might need to modify during its operation.
+
+For applications running in **Docker**, it's a common practice to mount this directory as an external volume. This ensures:
+
+- **Data Persistence**: App data is preserved across deployments.
+- **Easy Replication**: Facilitates seamless data replication for backup or migration purposes.
