 ## Installation
 
 1. Download and extract a [release archive](https://github.com/JanTvrdik/PhpVersionSwitcher/releases) to directory of your choice
+
 2. Update `PhpDir` and `HttpServerServiceName` options in `PhpVersionSwitcher.exe.config`
+
 3. Make sure the selected `PhpDir` has the following structure:
 
-```
-phpDir/
-├── configurations/
-│   ├── 5.x.x.ini # php.ini options for all 5.x.x versions
-│   ├── 5.3.x.ini # php.ini options for all 5.3.x versions
-│   ├── 5.3.7.ini # php.ini options specific for 5.3.7 version
-│   └── ...
-└── versions/
-	├── 5.3.4/
-	│   ├── ext/
-	│   ├── ...
-	│   └── php.exe
-	└── 5.6.0-rc3/
-		├── ext/
-		├── ...
-		└── php.exe
-```
-
-In all php.ini files you can use `%phpDir%` variable. This is especially useful for `zend_extension`, e.g.
-
-```
-zend_extension = "%phpDir%\ext\php_opcache.dll"
-zend_extension = "%phpDir%\ext\php_xdebug.dll"
-```
+	```
+	%phpDir%/
+	├── configurations/
+	│   ├── 5.x.x.ini # php.ini options for all 5.x.x versions
+	│   ├── 5.3.x.ini # php.ini options for all 5.3.x versions
+	│   ├── 5.3.7.ini # php.ini options specific for 5.3.7 version
+	│   └── ...
+	└── versions/
+		├── 5.3.7/
+		│   ├── ext/
+		│   ├── ...
+		│   └── php.exe
+		└── 5.6.0-rc3/
+			├── ext/
+			├── ...
+			└── php.exe
+	```
+
+4. Create php.ini files in the `configurations` directory. In all php.ini files you can use `%phpDir%` variable. This is especially useful for `zend_extension`, e.g.
+	```
+	zend_extension = "%phpDir%\ext\php_opcache.dll"
+	zend_extension = "%phpDir%\ext\php_xdebug.dll"
+	```
+
+5. The active PHP version is always simlinked to `%phpDir%\active`. You may want to add this directory to `PATH`.
+
+6. Update configuration of your HTTP server. The Apache 2.4 configuration related to PHP may look like this:
+	```
+	LoadModule php5_module "C:/Web/Soft/PHP/active/php5apache2_4.dll"
+	PHPIniDir "C:/Web/Soft/PHP/active"
+	```
+
+7. Run `PhpVersionSwitcher.exe`.
