+# Solana manual withdraw with CLI
+
+## 1. Environment Setup
+
+We've prepared a CLI in Solido to simplify your workflow. You'll need to:
+
+1. **Install Rust**:
+Follow the instructions at [Rust Installation](https://www.rust-lang.org/tools/install).
+
+```bash
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh source "$HOME/.cargo/env"rustup override set 1.60.0
+```
+
+2. **Install Solana CLI v1.13.7**:
+Visit [Solana CLI Installation](https://solana.com/docs/intro/installation).
+
+```bash
+sh -c "$(curl -sSfL https://release.solana.com/v1.13.7/install)"
+```
+
+3. **Install Solido CLI v2.1.0** from the official GitHub repository:
+See [Solido Releases](https://github.com/lidofinance/solido/releases/tag/v2.1.0).
+
+```bash
+git clone --recurse-submodules -b V2.1 https://github.com/lidofinance/solido solido_v2
+cd solido_v2
+cargo build --release
+```
+
+## 2. Transfer stSOL to Local Account
+
+⚠️ **Note**: Our CLI can only work with local keys. Consider using a new account for withdrawals to keep your main wallet secure. The withdrawal operation will utilize the following:
+
+- **`SOL_ACCOUNT_PUBKEY`**: Public key of the local Solana account.
+- **`STSOL_ACCOUNT_PUBKEY`**: Public key of the child stSOL account from **`SOL_ACCOUNT_PUBKEY`**.
+- **`KEYPAIR_FILE`**: Local file containing the keypair from **`SOL_ACCOUNT_PUBKEY`**.
+- **`STAKE_ACCOUNT_PUBKEY`**: Public key of the child stake account from **`SOL_ACCOUNT_PUBKEY`**.
+
+1. **Create a new local account**:
+
+```bash
+solana-keygen new --outfile ./local-keypair.json
+```
+
+Remember the **`KEYPAIR_FILE`** path and **`SOL_ACCOUNT_PUBKEY`** from the output.
+
+2. **Verify the new account with `SOL_ACCOUNT_PUBKEY`**:
+
+```bash
+solana balance SOL_ACCOUNT_PUBKEY
+```
+
+3. **Transfer stSOL to the local account using `SOL_ACCOUNT_PUBKEY`** and **note the transaction signature**.
+
+4. **Identify `STSOL_ACCOUNT_PUBKEY`**:
+
+⚠️ After transferring stSOL, a child account for stSOL is created under your local account. To proceed, locate this address by searching your **transaction signature** on [Solscan](https://solscan.io/) and saving the **Destination** pubkey found under **Instruction Details →#3 - Token Transfer**.

+
+## 3. Withdraw stSOL
+
+1. **Execute the withdrawal** to your stake account:
+
+```bash
+./target/release/solido --config ./solido_config.json --keypair-path KEYPAIR_FILE withdraw --amount-st-sol STSOL_AMOUNT
+```
+
+⚠️ **Note**: if you're seeing the following error:
+
+```bash
+Program log: The exchange rate is outdated, it was last computed in epoch 644, but now it is epoch 646.
+```
+
+Execute the following command to update the exchange rate
+
+```bash
+./target/release/solido --config solido_config.json --keypair-path KEYPAIR_FILE perform-maintenance
+```
+
+If you get an RPC response error, such as -32002, simply re-run the command.
+
+Once the exchange rate is updated, you should get a message "Updated exchange rate", and you can proceed to re-run the withdrawal command.
+
+2. Record the **`STAKE_ACCOUNT_PUBKEY`** for further steps.
+
+3. **Deactivate the stake account**:
+
+```bash
+solana deactivate-stake STAKE_ACCOUNT_PUBKEY --keypair KEYPAIR_FILE
+```
+
+⚠️ Wait for the epoch to end (~1-2 days) for the stake account to become inactive. Check the epoch status on [Solana Explorer](https://explorer.solana.com/).
+
+## 4. Transfer SOL to Main Account
+
+After the epoch ends, withdraw SOL from **`STAKE_ACCOUNT_PUBKEY`** to your main account, referred to as **`MAIN_ACCOUNT_PUBKEY`**.
+
+```bash
+solana withdraw-stake **STAKE_ACCOUNT_PUBKEY** \
+**MAIN_ACCOUNT_PUBKEY** SOL_AMOUNT \
+--keypair **KEYPAIR_FILE**
+```
