+<Tabs groupId="operating-systems">
+  <TabItem value="ubuntu" label="Ubuntu">
+
+```bash
+wget https://raw.githubusercontent.com/ton-blockchain/mytonctrl/master/scripts/install.sh
+sudo bash install.sh
+```

+  <TabItem value={'debian'} label={'Debian'}>

+wget https://raw.githubusercontent.com/ton-blockchain/mytonctrl/master/scripts/install.sh
+su root -c 'bash install.sh'
+```
+
+  </TabItem>
+</Tabs>
+
+**Flags:**
+
+- `-d` - **MyTonCtrl** will download a [dump](https://dump.ton.org/) of the latest blockchain state, significantly reducing synchronization time.
+- `-c <path>` - Specify a non-public liteserver for synchronization (optional).
+- `-i` - Ignore minimum requirements; use this only if you test the compilation process without running a real node.
+- `-m` - Sett the mode either `validator` or `liteserver`.
+- `-t` - Disable telemetry.
+
+**To use testnet**, `-c` flag with the value `https://ton.org/testnet-global.config.json`.
+
+The default value for the `-c` flag is `https://ton-blockchain.github.io/global.config.json`, which is default configuration for the mainnet.
