 Ideally manual running of docker containers is for advanced users, we recommend the script based approach described below for most users.
 
-The `scripts/build_run_docker_tests.sh` script will cover most usecases. The script allows the user to configure the fork(altair/bellatrix/capella..), image_name(specifies the container to use), number of cores, preset type(mainnet/minimal) and test all forks flags. Ideally this is the main way that users interact with the spec tests, instead of running it locally with varying versions of dependencies.

The script allows the user to configure the fork(altair/bellatrix/capella..), `$IMAGE_NAME` (specifies the container to use), number of cores, preset type (mainnet/minimal), and test all forks flags. Ideally, this is the main way that users interact with the spec tests instead of running it locally with varying versions of dependencies.
 
 E.g:
 - `./build_run_test.sh --p mainnet --n 16` will run the mainnet preset tests with 16 threads
