+### Building 🛠
+
+In order to start working on Chucker, you need to fork the project and open it in Android Studio/IntelliJ IDEA.
+
+Before committing we suggest you install the pre-commit hooks with the following command:
+
+```
+./gradlew installGitHook
+```
+
+This will make sure your code is validated against KtLint and Detekt before every commit.
+The command will run automatically before the `clean` task, so you should have the pre-commit hook installed by then.
+
+Before submitting a PR please run:
+
+```
+./gradlew build
+```
+
+This will build the library and will run all the verification tasks (ktlint, detekt, lint, unit tests) locally.
+This will make sure your CI checks will pass.
