+### Pre/Post Action
+Pre/Post Action can be used to move files/folders out of the way or execute additional commands on the server before and after the deployment process.  
+The `PLUGIN_PRE_ACTION` is executed *before* the `PLUGIN_CLEAN_DIR` (if set).  
+The `PLUGIN_POST_ACTION` is executed *after* the ftp "mirror" operation.  
+
+Multiple Actions can be set, they need to be divided by a semicolon `;` .  
+**Example:**  
+There is another project's folder ("project2") in a subfolder in the destination directory. We need to move this folder to a temporary location and restore it after the upload completed.
+```yaml
+PLUGIN_CLEAN_DIR: true
+PLUGIN_PRE_ACTION: mv /dest/project2 /temp/project2;
+PLUGIN_POST_ACTION: mv /temp/project2 /dest/project2;
+```
