+
+#### Pre Backup
+If you want to execute a custom script before a backup starts, you can drop bash scripts with the extension of `.sh` in the location defined in `SCRIPT_LOCATION_PRE`. See the following example to utilize:
+
+````bash
+$ cat pre-script.sh
+##!/bin/bash
+
+# #### Example Pre Script
+# #### $1=DB_TYPE (Type of Backup)
+# #### $2=DB_HOST (Backup Host)
+# #### $3=DB_NAME (Name of Database backed up
+# #### $4=BACKUP START TIME (Seconds since Epoch)ff
+# #### $5=BACKUP FILENAME (Filename)
+
+echo "${1} Backup Starting on ${2} for ${3} at ${4}. Filename: ${5}"
+````
+
+    ## script DB_TYPE DB_HOST DB_NAME STARTEPOCH BACKUP_FILENAME
+    ${f} "${dbtype}" "${dbhost}" "${dbname}" "${backup_start_time}" "${target}"
+
+
+Outputs the following on the console:
+
+`mysql Backup Starting on example-db for example at 1647370800. Filename: mysql_example_example-db_202200315-000000.sql.bz2
+
+
+#### Post backup
+If you want to execute a custom script at the end of a backup, you can drop bash scripts with the extension of `.sh` in the location defined in `SCRIPT_LOCATION_POST`. Also to support legacy users `/assets/custom-scripts` is also scanned and executed.See the following example to utilize:
