 # Sync from genesis
 
 This is the slowest (and most secure) way to sync your node, as your node goes through every block since the genesis block.
+There are two ways for syncing your node from genesis:
+
+1. Through an archival node RPC.
+2. Through the validated and archived blocks by KYVE.

+## 2. How to sync through KYVE
+
+KYVE is a blockchain that validates and archives chain data like Archway blocks and state-sync snapshots.
+The tool KSYNC provides the possibility to use the validated data in order to sync an Archway node
+to any height.

+More information about KSYNC can be found in the [KYVE Docs](https://docs.kyve.network/ksync).

+
+### KSYNC Installation
+
+#### Install with Go (recommended)
+
+Install the latest version:
+
+```bash
+go install github.com/KYVENetwork/ksync/cmd/ksync@latest
+```
+
+Run `ksync version` to verify the installation.
+
+#### Install from source
+
+You can also install from source by pulling the ksync repository and switching to the correct version and building
+as follows:
+
+```bash
+git clone [email protected]:KYVENetwork/ksync.git
+cd ksync
+git checkout tags/vx.x.x -b vx.x.x
+make ksync
+```
+
+This will build ksync in `/build` directory. Afterwards, you may want to put it into your machine's PATH like
+as follows:
+
+```bash
+cp build/ksync ~/go/bin/ksync
+```
+
+### Starting KSYNC (default)
+
+You can _block-sync_ from genesis up to live height with the blocks
+validated and archived by KYVE with the following command:
+
+```bash
+ksync block-sync --binary="/path/to/archwayd" --source="archway"
+```
+
+You can also continue the _block-sync_ from your current height to any
+target height you specify with `--target-height`.
+
+```bash
+ksync block-sync --binary="/path/to/archwayd" --source="archway" --target-height=<height>
+```
+
+### Starting KSYNC as a service
+
+Since syncing from genesis can take a while a service file can be used to 
+allow the automatic restart of the service.
+
+You can create a service file with:
+
+::highlight-card
+
+```bash
+nano /etc/systemd/system/archwayd.service
+
+```
+
+::
+
+And add the following content to the file:
+
+::highlight-card
+
+```service
+[Unit]
+Description=KSYNC Archway Node
+After=network-online.target
+[Service]
+User=$USER
+ExecStart=/home/$USER/go/bin/ksync block-sync --binary="/path/to/archwayd" --source="archway"
+Restart=always
+RestartSec=3
+LimitNOFILE=4096
+[Install]
+WantedBy=multi-user.target
+
+```
+
+::
+
+You can then reload the systemctl daemon:
+::highlight-card
+
+```bash
+
+sudo systemctl daemon-reload
+```
+
+::
+
+Enable the  service:
+
+::highlight-card
+
+```bash
 
+sudo -S systemctl enable archwayd
+```
+
+::
+
+And then start **archwayd** as a service:
+
+::highlight-card
+
+```bash
+
+sudo systemctl start archwayd
+```
+
+::
+
+
+You can then check that the service is properly running with:
+::highlight-card
+
+```bash
+
+sudo systemctl status archwayd
+```
