+# Mainnet Upgrade Guide: From Version v25 to v26
+
+## Overview
+
+- **v26 Proposal**: [Proposal Page](https://www.mintscan.io/osmosis/proposals/TODO)
+- **v26 Upgrade Block Height**: TODO
+- **v26 Upgrade Countdown**: [Block Countdown](https://www.mintscan.io/osmosis/blocks/TODO)
+
+## Hardware Requirements
+
+### Memory Specifications
+
+Although this upgrade is not expected to be resource-intensive, a minimum of 64GB of RAM is advised. If you cannot meet this requirement, setting up a swap space is recommended.
+
+#### Configuring Swap Space
+
+*Execute these commands to set up a 32GB swap space*:
+
+```sh
+sudo swapoff -a
+sudo fallocate -l 32G /swapfile
+sudo chmod 600 /swapfile
+sudo mkswap /swapfile
+sudo swapon /swapfile
+```
+
+*To ensure the swap space persists after reboot*:
+
+```sh
+sudo cp /etc/fstab /etc/fstab.bak
+echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
+```
+
+For an in-depth guide on swap configuration, please refer to [this tutorial](https://www.digitalocean.com/community/tutorials/how-to-add-swap-space-on-ubuntu-20-04).

+
+## Cosmovisor Configuration
+
+### Initial Setup (For First-Time Users)
+
+If you have not previously configured Cosmovisor, follow this section; otherwise, proceed to the next section.
+
+Cosmovisor is strongly recommended for validators to minimize downtime during upgrades. It automates the binary replacement process according to on-chain `SoftwareUpgrade` proposals.
+
+Documentation for Cosmovisor can be found [here](https://docs.cosmos.network/main/tooling/cosmovisor).
+
+#### Installation Steps
+
+*Run these commands to install and configure Cosmovisor*:
+
+```sh
+go install github.com/cosmos/cosmos-sdk/cosmovisor/cmd/cosmovisor@v1.0.0
+mkdir -p ~/.osmosisd
+mkdir -p ~/.osmosisd/cosmovisor
+mkdir -p ~/.osmosisd/cosmovisor/genesis
+mkdir -p ~/.osmosisd/cosmovisor/genesis/bin
+mkdir -p ~/.osmosisd/cosmovisor/upgrades
+cp $GOPATH/bin/osmosisd ~/.osmosisd/cosmovisor/genesis/bin
+mkdir -p ~/.osmosisd/cosmovisor/upgrades/v25/bin
+cp $GOPATH/bin/osmosisd ~/.osmosisd/cosmovisor/upgrades/v25/bin
+```
+
+*Add these lines to your profile to set up environment variables*:
+
+```sh
+echo "# Cosmovisor Setup" >> ~/.profile
+echo "export DAEMON_NAME=osmosisd" >> ~/.profile
+echo "export DAEMON_HOME=$HOME/.osmosisd" >> ~/.profile
+echo "export DAEMON_ALLOW_DOWNLOAD_BINARIES=false" >> ~/.profile
+echo "export DAEMON_LOG_BUFFER_SIZE=512" >> ~/.profile
+echo "export DAEMON_RESTART_AFTER_UPGRADE=true" >> ~/.profile
+echo "export UNSAFE_SKIP_BACKUP=true" >> ~/.profile
+source ~/.profile
+```
+
+### Upgrading to v26
+
+*To prepare for the upgrade, execute these commands*:
+
+```sh
+mkdir -p ~/.osmosisd/cosmovisor/upgrades/v26/bin
+cd $HOME/osmosis
+git pull
+git checkout v26.0.0
+make build
+cp build/osmosisd ~/.osmosisd/cosmovisor/upgrades/v26/bin
+```
+
+At the designated block height, Cosmovisor will automatically upgrade to version v26.
+
+---
+
+## Manual Upgrade Procedure
+
+Follow these steps if you opt for a manual upgrade:
+
+1. Monitor Osmosis until it reaches the specified upgrade block height: TODO.
+2. Observe for a panic message followed by continuous peer logs, then halt the daemon.
+3. Perform these steps:
+
+```sh
+cd $HOME/osmosis
+git pull
+git checkout v26.0.0
+make install
+```
+
+4. Restart the Osmosis daemon and observe the upgrade.
