-# sync.applescript
-An applescript for syncing files to a usb drive using rsync
+# sync.Applescript
+
+a tool to use rsync to sync files to an external folder
+
+* License: GPLv3.0
+* git: https://github.com/jakeosx/sync.applescript
+* version 1.0
+
+# About
+
+This app is designed to be run from the destination location and sync files found elsewhere. 
+
+So, for example, I keep a copy on a thumb drive. I plug in the drive, run the application and it syncs folders on the drive with folders on my computer, updating the changed files and deleted the deleted files. 
+
+# Requirements
+
+* macOS
+
+While the base syncing functions are rsync, which is available on many platforms, the wrapper application is AppleScript, which is a macOS specific language, and cannot be run elsewhere. 
+
+# WARNING
+
+When rsync deletes files they do not go into the trash, they are deleted, gone. Recommend using a copy of a folder to test out any settings before running live data.
+
+Which should be what you do with any random script you find on the internet, not just this one. 
+
+# TL:DR
+
+Put this script in the destination location. 
+
+Add the folders into my folders variable:
+
+```
+set myfolders to {"/path/to this folder/folder"}
+```
+
+Name the folder they go into in the backup variable, make it "" for the same location
+
+```
+set bckup to "bckup"
+```
+
+Once it is all set up to run, in Script Editor:
+
+File -> Export, select Application as file format
+
+# Setup
+
+
+
+Set the folders you want to sync:
+
+* format "/path/to/folder/", "path/to/otherfolder"
+* spaces as spaces, so "/path/to this folder/folder"
+* no trailing / 
+
+```
+set myfolders to {"/path/to this folder/folder"}
+```
+
+# Set the Name of the Folder at Destination
+
+Set the folder name you want all these things to be in. "Backup", for example. 
+
+```
+set backup to "backup"
+```
+
+If you want everything to go into the same location as the sync app, then just set this variable to blank, like so: 
+
+```
+set bckup to ""
+```
+
+# Rsync Settings
+
+Rsync is a powerful copying/syncing too. This AppleScript takes all the folders you have in your settings and runs them each through the rsync command: 
+
+```
+rsync -av --delete <ORIGIN> <DESTINATION>
+```
+
+Rsync is very powerful and can do lots of damage if you aren't careful. 
+
+The rsync manual: [https://download.samba.org/pub/rsync/rsync.html]()
+
+
+## What Does That Do? 
+
+Here's what those settings mean:
+
+* **-av** archive mode; verbose mode
+* **--delete** deletes the files at the destination that were deleted on the host
+
+Path variables are enclosed in " " so spaces can be allowed. 
+
+# All Done 
+
+Once it is all set up to run, in Script Editor:
+
+File -> Export, select Application as file format
+
+This will create a applet that you can double click to run directly, instead of opening the Script Editor application. 
+
+If you change settings in the script text file, you will need to repeat this export.
