 Combination of some codes and applications to create macOS installation media outside Mac app store.\
 Thanks me later :3
 
+## Motivation
+
+Honestly, the main reason is I've limited Internet. I can't download the whole 8GB, 12GB at one stroke. So, I've to download multiple times and MAS doesn't support it. Moreover, I want to save downloaded installer so that I can use them next time. That's why I made this script.
+
 ## How to Use
 
-it's still in beta. Simply, just edit `MACOS_VERSION` and `TARGET_DISK` variables and run the script.
+it's still in beta. Simply just run the script, answer the question and go!
 
-`TARGET_DISK` information can be found in `diskutil` > `table` > `Device`. In this example `disk3`. So, `TARGET_DISK` become `/dev/disk3`.
+`DISK SELECTION` information can be found in `diskutil` > `table` > `Device`. In this example `disk3`. So, `TARGET_DISK` become `/dev/disk3`.

 ```shell script
-$ git clone https://github.com/heinthanth/macos-bootable-usb
-$ cd macos-bootable-usb
+$ curl -LO https://github.com/heinthanth/macos-bootable-usb/releases/latest/download/macos-booable-usb-creator.sh
 $ ./creator.sh
 ```
 
+Optionally, you can verify the script with this command.
+
+``` shell script
+$ curl -LO https://github.com/heinthanth/macos-bootable-usb/releases/latest/download/SHASUM
+$ shasum creator.sh -c SHASUM
+```
+
+Moreover, if you don't trust `SHASUM` file, go check with `gpg`
+
+```
+$ curl -LO https://github.com/heinthanth/macos-bootable-usb/releases/latest/download/SHASUM
+$ curl -LO https://github.com/heinthanth/macos-bootable-usb/releases/latest/download/SHASUM.gpg
+$ gpg --keyserver hkp://keys.gnupg.net --recv-key 46D4B29338EE5105BCA79A142E1082FBF9CB91E9
+$ gpg --verify SHASUM.gpg SHASUM
+```
