 ## Synopsis
+
+```
+Usage: eos-pacdiff [options]
+```
+
+Run command
+
+```
+eos-pacdiff --help
+```
+to see the details about the options.
+
+Tip: option `--backup` enables creating backup files (with .bak) in modes view, merge, overwrite. This is a great safety measure, and one might consider writing an alias like:
+
 ```
-Usage: eos-pacdiff
+alias pacdiff='eos-pacdiff --backup'
 ```
 
+into file `~/.bashrc`.<br>
+Option `--backup` enables creating backup files in all 3 modes mentioned above.
+
+See also **Configuration** below.
+
+## Configuration
+
+File `/etc/pacdiff.conf` can contain the following (bash) variables, including their default values:
+
+```
+BACKUP_OVERWRITE=no
+BACKUP_VIEW=no
+BACKUP_MERGE=no
+```
+
+and their supported values are either `yes` or `no`.<br>
+They define whether the original config file will be saved with suffix `.bak` or not.
+
+_**Important note**_: if you want to be on the *safe* side, set the values of all `BACKUP_*` variables to `yes`. This creates the backup file also for any *critical* file (like `/etc/passwd`) if it was accidentally overwritten.
+
+Tip: command line options (e.g. `--backup`) will override the configuration variables.
