You can also specify the `REMOVE_OLD_MODS_DEPTH` (default is 16) variable to only delete files up to a certain level.
 
 For example: `-e REMOVE_OLD_MODS=TRUE -e REMOVE_OLD_MODS_INCLUDE="*.jar" -e REMOVE_OLD_MODS_DEPTH=1` will remove all old jar files that are directly inside the `plugins/` or `mods/` directory.

+JSON path based patches can be applied to one or more existing files by setting the variable `PATCH_DEFINITIONS` to the path of a directory that contains one or more [patch definition json files](https://github.com/itzg/mc-image-helper#patchdefinition) or a [patch set json file](https://github.com/itzg/mc-image-helper#patchset).
+
+Variable placeholders in the patch values can be restricted by setting `REPLACE_ENV_VARIABLE_PREFIX`, which defaults to "CFG_".
+
+The following example shows a patch-set file were various fields in the `paper.yaml` configuration file can be modified and added:
+
+```json
+{
+  "patches": [
+    {
+      "file": "/data/paper.yml",
+      "ops": [
+        {
+          "$set": {
+            "path": "$.verbose",
+            "value": true
+          }
+        },
+        {
+          "$set": {
+            "path": "$.settings['velocity-support'].enabled",
+            "value": "${CFG_VELOCITY_ENABLED}",
+            "value-type": "bool"

+          }
+        }
+      ]
+    }
+  ]
+}
+```
+
+> **NOTES:** Only JSON and Yaml files can be patched at this time. TOML support is planned to be added next. Removal of comments and other cosmetic changes will occur when patched files are processed.
