# Step 3: Initialize and Build the Züs components
### Initialize the Sharder and Miner directories
1. Navigate to 0chain directory
```
cd 0chain
```
2\. Run the `init.setup.sh` script located in the `docker.local/bin` directory using the command
```
./docker.local/bin/init.setup.sh
```
After running the script you will see the sharder and miner directories populated in `docker.local` folder.
3\. Lets verify whether the directories exist by navigating to `docker.local` folder and running
```
ls docker.local/
```
The output should be similar to this:
```
Makefile build.benchmarks build.sc_unit_test build.unit_test miner2 miner6 sharder2
benchmarks build.genkeys build.sharder config miner3 miner7 sharder3
bin build.magicBlock build.swagger docker-clean miner4 miner8 sharder4
build.base build.miner build.test.multisigsc miner1 miner5 sharder1 sql_script
```
### Build the miner and sharder containers
\
1\. Navigate to 0chain directory
```
cd 0chain
```
2\. First build the base containers using the script.(This may take few minutes)
```
./docker.local/bin/build.base.sh
```

3. Build mocks from the Makefile in the repo, from 0chain directory run:
```
make build-mocks
```
**Note:** Mocks have to be built once in the beginning. Building mocks require mockery and brew which can be installed from [**here**](/guides/setup-a-blockchain/additional-tips-and-troubleshooting-for-mac.md#install-homebrew-and-mockery-on-mac-and-linux) **.**
4. For building the sharder containers use the following command :
```
./docker.local/bin/build.sharders.sh
```

5. Build the miner containers using
```
./docker.local/bin/build.miners.sh
```

### Initialize the blobber directories
1. Navigate to blobber directory
```
cd blobber
```
2\. Inside blobber directory, run the commands below .The first command makes the shell script executable and while the next ones execute the shell script to create blobber directories.
```
chmod +x ./docker.local/bin/blobber.init.setup.sh
./docker.local/bin/blobber.init.setup.sh
```
**NOTE**: For Mac :
```
chmod +x ./docker.local/bin/blobber.init.setup-mac.sh
./docker.local/bin/blobber.init.setup-mac.sh
```
After running the script you will see the blobber directories populated in `docker.local` folder
3\. Let's verify whether the directories exist by navigating to `docker.local` folder and running
```
ls docker.local/
```
The output should be like this:
```
b0docker-compose.yml blobber4 Dockerfile
bin blobber5 IntegrationTestsBlobberDockerfile
blobber1 blobber6 keys_config
blobber2 docker-clean p0docker-compose.yml
blobber3 docker-compose.yml ValidatorDockerfilecd blobber/config
```
4. Navigate to the config directory using
```
cd blobber/config
```
Use the nano editor to edit the `block`\_`worker` field for both files :
```
nano 0chain_blobber.yaml
```
and
```
nano 0chain_validator.yaml
```
**Note : Change the default value of `block_worker` field with the following:** [**http://198.18.0.98:9091/**](http://198.18.0.98:9091/) **for the local chain.**
### Build the blobber containers
1. Go back to `blobber` directory
```
cd blobber
```
2\. Now run the following scripts located in the `docker.local/bin` directory.
```
./docker.local/bin/build.base.sh
./docker.local/bin/build.blobber.sh
./docker.local/bin/build.validator.sh
```

**Note:** The blobber scripts defined above works fine for Linux and Intel Mac **.**If you want to run blobber and validator on Apple Silicon Mac(M1 or M2) follow the guide [here](https://github.com/0chain/blobber/blob/staging/dev.local/README.md). In case you are still facing issues with blobbers on M1 or M2 mac check [Troubleshooting Guide for Blobbers Setup (Mac M1 or M2)](/guides/setup-a-blockchain/additional-tips-and-troubleshooting-for-mac.md#troubleshooting-guide-for-blobbers-setup-mac-m1-or-m2)[.](/guides/setup-a-blockchain/additional-tips-and-troubleshooting-for-mac.md#troubleshooting-guide-for-blobbers-setup-mac-m1-or-m2)
