 ## File Management
 
-### Copy files to the computer equipment in
+### Copy files from a device to a computer
 
 command:
 
 ```sh
-adb pull <file path on device> [directory on the computer]
+adb pull <remote> [local]
 ```
+> - `remote`: file path on device
+> - `local`: directory on computer
 
-The parameters on which the directory `` computer can be omitted, it defaults to the current directory.
+The `local` parameter is optional, the default value is current directory.
 
-example:
+For example:
 
 ```sh
 adb pull /sdcard/sr.mp4 ~/tmp/
 ```
 
-* Tips: * file path on the device may need root privileges to access, if your equipment has been root, you can use the `adb shell` and` su` command to obtain root privileges adb shell Lane after the first `cp / path / on / device / sdcard / filename` copy files to sdcard, then `adb pull / sdcard / filename / path / on / pc`.
+- *Tips*: The file from device may be not readable without root permission, you need to make sure your device is rooted and then use `adb shell` and `su` commands to gain the root permission in the `adb shell` environment, after that you can use `cp /path/on/device /sdcard/filename` to copy the target file from those directories which require root permission to a public directory, and finaly you can use `adb pull /sdcard/filename /path/on/pc` normally as mentioned above after exiting the `adb shell` environment.
