  > Sensible SQL support for Skript.
 ---
 
-### Difference from original skript-db
-- Fixed local variables disappearance in newer Skript versions (very hacky fix, but it works, so that's good!)
-- 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
-- If a sql query is detected to be running on non-main thread, it becomes synchronous automatically
-- SQL Driver is configurable both in config and in database connection, comes with shaded MariaDB and PostgreSQL drivers
-- 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.
 
- The url format for your database may vary depending on database you are using. 
- MariaDB/PostgreSQL users: make sure to check `config.yml` to use the correct driver.
+ The url format for your database may vary! The example provided uses a MySQL database.
 #### Syntax
 ```
-[the] data(base|[ ]source) [(of|at)] %string% [with [a] [max[imum]] [connection] life[ ]time of %timespan%] [[(using|with)] [a] driver %-string%]
+[the] data(base|[ ]source) [(of|at)] %string%
 ```
 
 #### Examples
 ```
 set {sql} to the database "mysql://localhost:3306/mydatabase?user=admin&password=12345&useSSL=false"
-set {sql} to the database "mariadb://localhost:3306/mydatabase?user=admin&password=12345&useSSL=false"
-set {sql} to the database "postgresql://localhost:3306/mydatabase?user=admin&password=12345&ssl=false"
-set {sql} to the database "sqlite:database.db"
-
-# Extra parameters:
-set {sql} to the database "postgresql://localhost:3306/mydatabase?user=admin&password=12345&ssl=false" with a maximum connection lifetime of 30 minutes
-set {sql} to the database "postgresql://localhost:3306/mydatabase?user=admin&password=12345&ssl=false" with a maximum connection lifetime of 30 minutes using driver "org.postgresql.Driver"

-#### FAQ: How to return sql data in a function?
-You can't because functions don't allow delays, but you can use skript-reflect sections for this:
-```
-on load:
-	create new section stored in {-section::getPlayersFromDatabase}:
-		execute "SELECT uuid FROM table" in {-sql} and store the result in {_result::*}
-		return {_result::uuid::*}
-command /showplayers [<text>]:
-	trigger:
-		run section {-section::getPlayersFromDatabase} async and store result in {_uuids::*} and wait
-		send "%{_uuids::*}%"
-```
 ---
-### Configuration
-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"
