     These options are provided to empower you to get your server up and running quickly. Please help out by reporting an issue with the respective mod project. Ideally mod developers should [use correct registrations for one-sided client mods](https://docs.minecraftforge.net/en/latest/concepts/sides/#writing-one-sided-mods). Understandably, those code changes may be non-trivial, so mod authors can also add "Client" to the game versions when publishing.
 
-## Extra options
+## Excluding Overrides Files
+
+Modpack zip files typically include an `overrides` subdirectory that may contain config files, world data, and extra mod files. All of those files will be extracted into the `/data` path of the container. If any of those files, such as incompatible mods, need to be excluded from extraction, then the `CF_OVERRIDES_EXCLUSIONS` variable can be set with a comma or newline delimited list of ant-style paths ([see below](#ant-style-paths)) to exclude, relative to the overrides (or `/data`) directory. 
+
+### Ant-style paths
+
+Ant-style paths can include the following globbing/wildcard symbols:
+
+| Symbol | Behavior                                                |
+|--------|---------------------------------------------------------|
+| `*`    | Matches zero, one, or many characters except a slash    |

+| `?`    | Matches one character                                   |
+
+!!! example
+    
+    The following compose `environment` entries show how to exclude Iris and Sodium mods from the overrides
+    
+    ```yaml
+      CF_OVERRIDES_EXCLUSIONS: mods/iris*.jar,mods/sodium*.jar
+    ```
+    
+    or using newline delimiter, which improves maintainability
+    
+    ```yaml
+      CF_OVERRIDES_EXCLUSIONS: |
+        mods/iris*.jar
+        mods/sodium*.jar
+    ```
+
+## World/Level Data
 
 Some modpacks come with world/save data via a worlds file and/or the overrides provided with the modpack. Either approach can be selected to set the `LEVEL` to the resulting saves directory by setting `CF_SET_LEVEL_FROM` to either:
 - `WORLD_FILE`
 - `OVERRIDES`
 
+## Extra options
+
 Other configuration available:
 - `CF_PARALLEL_DOWNLOADS` (default is 4): specify how many parallel mod downloads to perform
 - `CF_OVERRIDES_SKIP_EXISTING` (default is false): if set, files in the overrides that already exist in the data directory are skipped. **NOTE** world data is always skipped, if present.
