+#### Recommended method to start (Using Docker)
+To avoid compatibility issues with GCC, GLIBC, and Go versions, we recommend using Docker:
+```bash
+docker build -t cdk-erigon:latest .
+docker run -it --rm \
+    -p 8545:8545 \
+    -p 30303:30303 \
+    -v "$PWD/xlayerconfig-mainnet.yaml:/home/erigon/xlayerconfig-mainnet.yaml" \
+    cdk-erigon:latest \
+    --config=/home/erigon/xlayerconfig-mainnet.yaml
+```
+
+If you prefer a manual installation, follow the steps below.
+
 #### Start Erigon Node
 ```
 ./build/bin/cdk-erigon --config="./xlayerconfig-mainnet.yaml"
 ```
+
+### Quick Start with Snapshot (Recommended)
+To avoid the time-consuming process of syncing from genesis, you can download the latest snapshots from our official snapshot page:
+
+Access the Official Snapshot Page
+Visit our official snapshot repository at:
+https://static.okex.org/cdn/chain/xlayer/snapshot/index.html
+
+This page provides the latest snapshots for both X Layer mainnet and testnet. Snapshots are updated every Webnesday and Sunday, with the latest update timestamp displayed on the page.
+
+#### Downloading and Using Snapshots
+##### Downloading snapshots
+
+```
+# Create a directory for your data
+mkdir -p /data/erigon 
+cd /data/erigon
+# Download the snapshot from the snapshot page
+# Replace with the actual download link from the snapshot page
+wget <snapshot-url-from-snapshot-page>
+```
+
+##### Extract the snapshot
+```
+# Extract the snapshot (this may take some time)
+tar -xzf <downloaded-snapshot-file>
+```
+
+##### Update your configuration
+Edit your xlayerconfig-mainnet.yaml file to point to the extracted data directory:
+```
+datadir: /data/erigon/extracted-snapshot-directory
+```
+##### Start Erigon with the snapshot data
+```
+./build/bin/cdk-erigon --config="./xlayerconfig-mainnet.yaml"
+```
+
+#### Using Snapshots with Docker
+If you're using Docker, mount the extracted data directory as a volume:
+```
+docker run -it --rm \
+    -p 8545:8545 \
+    -p 30303:30303 \
+    -v "/data/erigon/extracted-snapshot-directory:/home/erigon/data" \
+    -v "$PWD/xlayerconfig-mainnet.yaml:/home/erigon/xlayerconfig-mainnet.yaml" \
+    cdk-erigon:latest \
+    --config=/home/erigon/xlayerconfig-mainnet.yaml
+```
+Make sure to update your config file's datadir to point to /home/erigon/data. The rest is same as the instructions above.
