# Step 4: Start Sharder and Miner Containers To start all the miner and sharder containers navigate to the `0chain/docker.local/` directories and run the start script. For example, let's run 1 sharder and 3 miners. 1. Open four different terminal tabs and in the first terminal tab navigate to the `0chain/docker.local/sharder1` directory using ``` cd 0chain/docker.local/sharder1/ ``` 2.Run the following command for starting the sharder ``` ../bin/start.b0sharder.sh ``` 3.Wait till the Cassandra is started and the sharder is ready to listen to requests. Here is a screenshot of sharder up and running:

4\. Repeat steps 1 and 2 by changing the sharder1 directory to (sharder 2,3 etc) in new terminal tabs to start more sharders. Notes : * Run each sharder on new terminal tab and start sharder before miners as they need the genesis magic block. * Run the command specified in step 2 by only navigating to sharder directories. * If you are not able to locate sharder directories, have a look at the[ Initialize the Miner and sharder directories](https://github.com/0chain/gitbookdocs/blob/main/broken-reference/README.md) section. * **For a minimal working setup, at least run 1 sharder and 3 miners.** 5\. To run the miner containers in other three terminal tabs,first navigate to `0chain/docker.local/miner1` directory using ``` cd 0chain/docker.local/miner1/ ``` 6\. Run the following command for starting the miner ``` ../bin/start.b0miner.sh ``` Wait till the miner is ready to accept connections. Here is a screenshot of miner up and running.

7\. Repeat steps 5 and 6 by changing the miner1 directory to (miner 2,3 etc) in new terminal tabs to start more miners. **Notes:** * Run each miner on a new terminal tab * To avoid errors, run the command specified in step 6 by only navigating to miner directories. * If you are not able to locate miner directories, have a look at the [Initialize the Miner and sharder directories](https://github.com/0chain/gitbookdocs/blob/main/broken-reference/README.md) section. * **For a minimal working setup, at least run 1 sharder and 3 miners.** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
