     ```shell
-    cd rentals
-    ## Compile the PHP code on MacOS using openssl
-    brew install openssl
-    export OPENSSL_DIR=$(brew --prefix openssl)
-    export LDFLAGS="-L$OPENSSL_DIR/lib"
-    export CPPFLAGS="-I$OPENSSL_DIR/include"
-    export PKG_CONFIG_PATH="$OPENSSL_DIR/lib/pkgconfig"

+    ```
+    Once installed, you can start with mongodb driver installation for PHP
 
+    ```shell
+    cd rentals
     pecl install mongodb
     ```
