## Building and Testing
The beacon chain components require that you have Nim installed - the easiest way to get started is to head over to the main [Nimbus](https://github.com/status-im/nimbus/) repository and follow the build instructions there.
The beacon chain components require that you have Nim installed - the easiest way to get started is to head over to the main [Nimbus](https://github.com/status-im/nimbus/) repository and follow the build instructions there or just execute the commands below in order.
_Note: This is because this repository is actually pulled in as a dependency of Nimbus - the Ethereum 1.0 + 2.0 client - so it makes sense to start from there even if you are only interested in testing the Ethereum 2.0 side of things (contained almost entirely in this repository)._

Alternatively, the Makefile flow is available from the Nimbus parent repo:
```bash
# In the Nimbus repo root
# Start beacon chain simulation, resuming from the previous state (if any)
make eth2_network_simulation
# Clear data from last run and restart simulation with a new genesis block
make clean_eth2_network_simulation_files eth2_network_simulation
```
You can also separate the output from each beacon node in its own panel, using [multitail](http://www.vanheusden.com/multitail/):
```bash
USE_MULTITAIL="yes" ./tests/simulation/start.sh
# OR
USE_MULTITAIL="yes" make eth2_network_simulation
```
You can find out more about it in the [development update](https://our.status.im/nimbus-development-update-2018-12-2/).
