+# Running Kics with pre-commmit
+
+To use `kics` with [pre-commit](https://pre-commit.com) add the following hook to your local repo's `.pre-commit-config.yaml` file. 
+
+```yaml
+- repo: https://github.com/Checkmarx/kics
+  rev: '' # change to correct tag or sha
+  hooks:
+    - id: kics
+```
+
+## How to pass extra arguments
+
+You can provide arguments to `kics` by providing the pre-commit `args` [property](https://pre-commit.com/#passing-arguments-to-hooks). The following example will print the `kics scan` output, but will not block regardless of success/failure.
+
+```yaml
+repos:
+- repo: https://github.com/Checkmarx/kics
+  rev: '' # change to correct tag or sha
+  hooks:
+  - id: kics
+    verbose: true
+    args: [--ignore-on-exit, 'all']
+```
