 - `1.x.x`: MySQL 5.6 (also supports MySQL 5.5 but not all spatial analysis functions)
-- `2.x.x`: MySQL 5.7 and 8.0
+- `2.x.x`: MySQL 5.7
+- **`3.x.x`: MySQL 8.0 with SRID support (Current branch)**
 
 This package also works with MariaDB. Please refer to the [MySQL/MariaDB Spatial Support Matrix](https://mariadb.com/kb/en/library/mysqlmariadb-spatial-support-matrix/) for compatibility.
 
 ## Installation
 
 Add the package using composer:
 
+```sh
+$ composer require grimzy/laravel-mysql-spatial
+```
+
+For MySQL 5.7:
+
 ```shell
-composer require grimzy/laravel-mysql-spatial
+$ composer require grimzy/laravel-mysql-spatial:^2.0
 ```
 
 For MySQL 5.6 and 5.5:
 
 ```shell
-composer require grimzy/laravel-mysql-spatial:^1.0
+$ composer require grimzy/laravel-mysql-spatial:^1.0
 ```
 
 For Laravel versions before 5.5 or if not using auto-discovery, register the service provider in `config/app.php`:
