+### Auto-assigning issues
+
+We have a workflow that automatically assigns issues to users who comment 'take' on an issue. This is configured in the `.github/workflows/assign-on-comment.yml` file. When a user comments `take` on the issue, a GitHub Action will be run to assign the issue to the user if it's not already assigned.

 To run spark tests you need to have properly configured Java. Apache Spark currently supports mainly only Java 8 (1.8). You can find an instruction on how to set up Java [here](https://www.java.com/en/download/help/download_options.html). When you are running spark tests you should have `JAVA_HOME` variable in your environment which points to the  installation of Java 8.
 
+### Pre-commit installation and execution
+
+We use pre-commit hooks to ensure code quality. The configuration for pre-commit hooks is in the `.pre-commit-config.yaml` file. To install pre-commit, run:
+```shell
+poetry shell
+poetry run pre-commit install
+```
+To run pre-commit hooks manually, use:
+```shell
+pre-commit run --all-files

+### GitHub Actions local setup using 'act'
+
+You can run GitHub Actions locally using the `act` tool. The configuration for GitHub Actions is in the `.github/workflows/ci.yml` file. To install `act`, follow the instructions [here](https://github.com/nektos/act#installation). To run a specific job, use:
+```shell
+act -j <job-name>
+```
+For example, to run the `test` job, use:
+```shell
+act -j test
+```
+If you need help with `act`, use:
+```shell
+act --help
+```
+For MacBooks with M1 processors, you might have to add the `--container-architecture` tag:
+```shell
+act -j <job-name> --container-architecture linux/arm64
