# Installation

> Run a Dymension Hub full node (Cosmos SDK). Build the `dymd` binary, join the right network, and sync.

<Note>
  This keeps to the official flow: build `dymd`, fetch the **genesis** and **seeds**, select **mainnet** or **testnet**, then start and monitor sync.
</Note>

## Prerequisites

* Linux with **Go** toolchain.
* Open typical Cosmos ports (26656 p2p, 26657 RPC, 1317 REST, 9090 gRPC) as needed.

## 1) Build `dymd`

```bash theme={null}
git clone https://github.com/dymensionxyz/dymension.git --branch v3.2.0
cd dymension
make install
dymd version --long
```

If `dymd` isn’t on your PATH:

```bash theme={null}
export PATH=$PATH:$(go env GOPATH)/bin
```

## 2) Initialize

```bash theme={null}
dymd init mynode --chain-id dymension_1100-1
```

## 3) Genesis & seeds

* Download the **genesis.json** and **seed nodes** from the “Join a network” page, then place the files here:

```bash theme={null}
# genesis
cp /path/to/genesis.json ~/.dymension/config/genesis.json

# seeds (comma-separated) into app.toml / config.toml as instructed
```

## 4) Start & monitor

```bash theme={null}
dymd start
# In another terminal:
dymd status | jq .SyncInfo
```

Sync is complete when `catching_up` becomes `false` and the latest block height matches public explorers.

## 5) (Optional) Snapshot

To accelerate sync, use a trusted **snapshot** (community-provided) and ensure `~/.dymension/data` is emptied beforehand, then restart the node.

## Notes

* Mainnet chain-id: **dymension\_1100-1**.
* After you’re fully synced, you can proceed to validator creation separately.
