 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`:
+1. [Build](./README.md#build) yourself and follow the latest [Release Notes](./RELEASE_NOTES.md). Make sure you run the right binary for the testnet or the mainnet. Consult the chain upgrades on [mainnet](https://www.mintscan.io/umee/proposals) and [testnet](https://explorer.network.umee.cc/Canon-4/gov).

+2. 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):
