+To integrate selene with git, you can use [pre-commit](https://pre-commit.com). Once you have [pre-commit installed](https://pre-commit.com/#install), add this to the `.pre-commit-config.yaml` at root of your repository:
+```yaml
+repos:
+  - repo: https://github.com/Kampfkarren/selene
+    rev: '' # Change this value to use a different version of Selene
+    hooks:
+      - id: selene-system # Use the selene binary already present on system path
+      - id: selene-docker # To use docker to run the hook, needs docker to be present
+```
+You need to mention only one of the two hooks ids depending upon if you already have the binary available or not on your system path.
