+### Version 2.1.0 (code 210) changelog
-    - Instead of make, it was switched to build with NDK
+    - The main usage structure has been changed.
-    - File/partition sizes were given during backup/flash operations.
+    - A more organized and functional code was provided. For example, separate values were not used for the same type of control all the time. Everything was done with a single function.
-    - The use of `fprintf` has started for all error messages.
+    - Smoother error processing was performed.
+    - There were a lot of arguments, it was cleared up. So the usage change I mentioned above has occurred.
+    - The exit codes were organized according to the sysexits library.
+    - Better deb builder script.
+    - In short, a lot of missing and errors that happened in 2.0.0 have been fixed

 This binary C is for manage partitions of android devices.
 It offers a lot of options. I will place these below. But first let me talk about the operation...
 
-```
-1. The partition name is obtained (with the -p or --partition argument)
-2. Other arguments (if used) are processed.
-3. The backup and flashing processes were written according to DD's code. So there is a piece of toybox code
-```

 #### Presented arguments (options)
 
 ```
 Usage:
-   -b | --backup      backup mode
+   pmt backup PARTITION [OUTPUT] [OPTIONS]...
-   -F | --flash       flash mode
+   pmt flash FILE PARTITION [OPTIONS]...
-   -r | --format      format mode (only ext2/3/4 file systems)
+   pmt format FILE_SYSTEM[ext/2/3/4] PARTITION [OPTIONS]...
-   -p | --partition   name of the partition to be backed up
+
-   -l | --logical     know that the partition that will be backed up is logical
+Options:
-   -o | --out         (only backups) the output name of the backed-up partition (default: partition name)
+   -l | --logical     it is meant to determine whether the target partition is logical
-   -d | --outdir      (only backups) directory where the backup partition will be saved (default: /storage/emulated/0)
    -c | --context     it is meant to specify a custom /dev context. Only classic partitions (default: /dev/block/by-name)
-   -D | --list        list partitions
+   -p | --list        list partitions
-   -f | --force       force mode. Output is not produced. Even if it's a mistake. But if the target is not a mode, the error is given. If you want to work stable, it is important to specify this option first.
+   -s | --silent      information and warning messages are silenced in normal work.
+   -f | --force       force mode. Error messages are silenced and some things are ignored.
    -v | --version     see version
         --help        see help message
    -L | --license     see license
 
 Examples:
-   -b --partition boot_a -o boot_slot_a_image -d /sdcard/backup -c /dev/block/platform/bootdevice/by-name
+   pmt backup boot_a -c /dev/block/platform/bootdevice/by-name
-   --flash /sdcard/twrp/boot.img -p boot_a -c /dev/block/platform/bootdevice/by-name
+   pmt flash /sdcard/twrp/boot.img boot_a -c /dev/block/platform/bootdevice/by-name
-   -c /dev/block/platform/bootdevice/by-name --list

-- İt is mandatory to use the `-b` | `--backup` or `-f` | `--flash` and `-p` | `--partition` argument. After all, a partition name and progress type is required to be progress.
 - If the logical partition flag is not used, a classic partition is tried to be processing by default.
