+# Validator Notes
+
+This document describes a process of joining a testnet or a mainnet as a validator.
+
+## Umeeversity
+
+Full documentation is hosted at [learning.ux.xyz](https://learning.ux.xyz). However it may not be up to date.
+
+## Getting a Binary
+
+To run a validator you need 2 binaries: `umeed` and `price-feeder`.
+
+### Umeed
+
+You can get a binary by:
+
+1. [Build](./README.md#build) yourself and follow the latest [Release Notes](./RELEASE_NOTES.md).
+   If you build the binary on a different OS than your validator OS, then you need to copy `libwasmvm`:
+
+   ```sh
+   scp $GOPATH/pkg/mod/github.com/!cosm!wasm/wasmvm@<version>/internal/api/libwasmvm.$(uname -m).so running_os:/<lib/path>
+   ```
+
+   NOTE: use the correct `wasmvm` version, according to the latest [Release Notes](./RELEASE_NOTES.md) or the [compatibility matrix](./README.md#release-compatibility-matrix).
+
+2. Download latest [binary build](https://github.com/umee-network/umee/releases). The build is compatible with the latest Ubuntu LTS x86-64. You MUST also copy the `libwasmvm` (see note in 1. about libwasmvm version):
+
+   ```sh
+   wget https://raw.githubusercontent.com/CosmWasm/wasmvm/<version>/internal/api/libwasmvm.$(uname -m).so -O /lib/libwasmvm.$(uname -m).so
+   ```
+
+3. Use our released docker [umeed container](https://github.com/umee-network/umee/pkgs/container/umeed).
+
+To test if the `libwasm` is linked correctly, run `umeed version`.
+
+### Price Feeder
+
+We are using Ojo Price Feeder. Please follow the [instructions](https://github.com/ojo-network/price-feeder/blob/umee/README.md). Make sure you use the latest release with the `umee/` prefix (eg: `umee/v2.4.0`).
+NOTE: for self building and configuration examples you MUST use the [umee branch](https://github.com/ojo-network/price-feeder/tree/umee).
+
+- Copy the [`price-feeder.toml`](https://github.com/ojo-network/price-feeder/blob/umee/price-feeder.example.toml).
+- For the provider config you can use our latest [umee-provider-config directory](https://github.com/ojo-network/price-feeder/tree/umee/umee-provider-config) as is.
+
+## Running a node
+
+1. Update the `app.toml` , `client.toml` and `config.toml` based on your preference. You MUST set non zero min gas prices in `app.toml`. Query `umeed q ugov min-gas-price` to see the what is the minimum acceptable value:
+
+   ```toml
+   # your app.toml file
+   minimum-gas-prices = "0.1uumee"
+   ```
+
+## Joining the network
+
+Before joining the mainnet you should join a testnet!
+
+### Testnet
+
+1. Make sure your are able to run `umeed` and price feeder locally.
+2. Join the [Discord server](https://discord.gg/4ZJAFvg9). Make sure you are in the Testnet group.
+3. Follow the state sync [canon-4 instructions](https://mzonder.notion.site/UMEE-Start-from-STATE-SYNC-canon-4-f485563a089a436d9d1fe98f54af8737). Make sure you use the [latest](https://github.com/umee-network/umee/releases/) version.
+4. You can use the following peers in your `config.toml`:
+
+   ```toml
+   persistent_peers = "[email protected]:10000,[email protected]:10001"
+   ```
+
+5. Using discord, ping one of the UX Team members to send you testnet `uumee`.
+6. Once your validator is setup (and you did self delegation), ping again UX Team members and send your validator address. We will do a delegation.
+7. Make sure your Price Feeder is running correctly. If your [testnet window misses](https://canon.price-feeder.com/) are above 50% then something is wrong. Look for a help on Discord.
+
+Here are our testnet public endpoints:
+
+- [Explorer](https://explorer.network.umee.cc/canon-4)
+- [Web GRPC](https://canon-4.api.network.umee.cc)
+- [RPC](https://canon-4.rpc.network.umee.cc)
+
+### Mainnet
+
+1. Make sure you firstly tested your setup on Testnet.
+2. Use one of the community [snapshots & instructions](https://github.com/obajay/StateSync-snapshots/tree/main/Projects/Umee).
+3. Buy `uumee` to self delegate.
+4. Make sure your Price Feeder is running correctly. If your [mainnet window misses](https://price-feeder.com/) are above 50% then something is wrong. Look for a help on Discord.
+
+We recommend to use [Cosmovisor](./README.md#cosmovisor) for mainnet nodes.
