 ### Build and Test
 ```bash
-# Full build with all tests
-mvn install
-
-# Build and test (recommended)
+# Build and test via Mise (requires mise installed)
 ./build_and_test
-
-# Skip tests if some are machine/locale dependent
-mvn install -DskipTests
-
-# Run tests for specific module
-mvn verify -pl approvaltests-tests/
 ```
 
-### Development
-```bash
-# Format code
-mvn formatter:format
-
-# Run just the main tests
-./run_tests_without_compile_dependencies.sh
-```
+**Note:** The project uses [Mise](https://mise.jdx.dev/) for task automation. The `.mise.toml` file defines tasks like `build_and_test` and `format`. Java version is specified in `.java-version` file.
 
 ## Key Files and Concepts
 
-- **Approved files**: `*.approved.*` files must be committed to source control and treated as binary in git (add `*.approved.* binary` to `.gitattributes`)
-- **Received files**: Generated during test failures, showing actual output vs approved
-- **Reporters**: Tools that show diffs when tests fail (IntelliJ, Beyond Compare, etc.)
-- **Namers**: Determine approval file naming based on test method/class
-- **Writers**: Generate the actual content to be approved
+- **Approved files**: `*.approved.*` files must be committed to source control. These are automatically treated as binary in git via `.gitattributes` (`*.approved.* binary diff`)
+- **Received files**: `*.received.*` files generated during test failures, showing actual output vs approved. These should not be committed
+- **Reporters**: Tools that show diffs when tests fail (IntelliJ, Beyond Compare, etc.). Located in `org.approvaltests.reporters`

 ## Running Single Tests

+**Note:** Tests run with `en_US` locale by default (configured in surefire plugin) to ensure consistent output across different environments.

 ## Code Style
 
-The project uses the formatter plugin with configuration in `spun.xml`. Code formatting is enforced via Maven build.
+There is an automatic code formatter that is used every time you build the project.
