 ### Difference from original skript-db
 - Fixed local variables disappearance in newer Skript versions (very hacky fix, but it works, so that's good!)
-- Thread-pool size is now automatically increasing on demand to use of CachedThreadPool, instead of a fixed hard-coded number
-- Uses a newer version of HikariCP
-- Only meant to be used by newer Minecraft versions (1.8 is not supported)
+- Thread-pool size is now automatically increasing on demand with use of CachedThreadPool, instead of a fixed hard-coded number
+- Uses newer versions of dependencies (Increased performance and security)
 - Replaced `synchronously execute` with `quickly execute`, which allows to speed up queries by 50ms with some risk
+- SQL Driver is configurable
+- A few variable type related bugs fixed
+- Uses Java 11 instead of Java 8
 
+### Installation
+1. Use 1.8+ Minecraft server version.
+2. Use Skript 2.5+ (1.8 Skript fork is needed if you're using 1.8)
+3. Use Java 11+ (If you use 1.8, a spigot fork is needed to support Java 11+)
+4. Put skript-db in plugins folder and restart the server
 ### Expression `Data Source` => `datasource`
 Stores the connection information for a data source. This should be saved to a variable in a
  `script load` event or manually through an effect command.

+plugins/skript-db/config.yml
+```
+# Only change this if you wish to use a different driver than Java's default, like MariaDB driver.
+# If you use MariaDB, its driver is shaded together with skript-db, so you can just specify: "org.mariadb.jdbc.Driver"
+sql-driver-class-name: "default"
