+* PowerShell 4.0 (or higher)
+* [Drive Snapshot](http://www.drivesnapshot.de/) (tested with version 1.45)
+
+## Basic installation
+
+1. Copy *dsmonrot.ps1* to arbitrary directory (for example *C:\DSMonRot*). You should also sign this script file or set PowerShell execution policy to *Unrestricted*.
+2. Download Drive Snapshot from http://www.drivesnapshot.de/ and copy it to the directory mentioned in the step above
+3. Create a directory for your backups (for example *D:\Backup*)
+4. Edit *dsmonrot.ps1* and edit the following variables:
+ 1. Set ``$backupDir`` to the path you created in step 3
+ 2. Specify the disks and partitions you want to backup in ``$disksToBackup``, see http://www.drivesnapshot.de/en/commandline.htm for syntax
+ 3. Adjust ``$dsPath`` to point to the path of Drive Snapshot (for example *C:\DSMonRot\snapshot.exe*)
+ 4. Specify the number of months to keep the backups by adjusting ``$keepMonths`` (the current month does not count, so if you set this variable to ``2``, DSMonRot keeps the current month **and** the last two months), set to ``0`` if you only want to keep the current month, set to ``-1`` if you don't want to delete any backup (not recommended)
+ 5. After adjusting ``$keepMonths``, you should also adjust ``$keepLogs`` to at least the same amount. This variable controls the number of log files, DSMonRot keeps.
+ 5. If your backup directory is on a SMB share, you have to edit the variables ``$smbDrive``, ``$smbPath``, ``$smbUser`` and ``$smbPassword``
+ 6. If you want DSMonRot to send a mail if an error occurs, you have to edit the variables ``$emailOnError``, ``$emailFromAddress``, ``$emailToAddress``, ``$emailSubject``, ``$emailMailserver``, ``$emailPort``, ``$emailSSL``, ``$emailAuth``, ``$emailUser`` and ``$emailPassword``
+ 7. If you want to adjust more configuration variables, just have a look at the comments preceeding each variable.
+5. Configure Windows task planner to execute the script
