+You can test an Ocean Protocol application (such as a marketplace) against the test networks (testnets) described below. This page is a brief overview of those testnets. The [tutorials](/tutorials/) cover more details (e.g. how to connect to specific ones).
 
 ## The Kovan Testnet
 
 The [Kovan Testnet](https://github.com/kovan-testnet/proposal) (or just "Kovan") is a public Ethereum Testnet operated by members of the Ethereum community.
 
-Most Ethereum wallets and libraries know how to connect to the Kovan Testnet. If you're using [Barge](https://github.com/oceanprotocol/barge) to run a local Kovan node, you can connect to that local Kovan node at RPC URL [http://localhost:8545](http://localhost:8545) (called "Localhost 8545" in MetaMask).
-
 ### Kovan Blockchain Explorers
 
 There are some Kovan blockchain explorers, e.g. [Etherscan for Kovan](https://kovan.etherscan.io/) and [BlockScout for Kovan](https://blockscout.com/eth/kovan). You can use those to check the status of a transaction, the balance of an account, and more.
 
-### Keeper Contracts on Kovan
-
-The Ocean Protocol [keeper contracts](https://github.com/oceanprotocol/keeper-contracts) (smart contracts) are deployed on Kovan. In fact, several versions of the keeper contracts have been deployed there. You can find the addresses of recently-deployed keeper contracts (including the OceanToken contract) as follows:
-
-1. Go to [the list of keeper-contracts releases (Git tags) on GitHub](https://github.com/oceanprotocol/keeper-contracts/releases).
-1. Click on the name of a release's Git tag in the left sidebar. It will look something like `v0.8.3`.
-1. Scroll down to the **Kovan Testnet** section of the README.md file. The contract addresses are listed there. Note: Sometimes there is a disconnect between the release number and the listed version number.
-
-Note: Because Ocean Protocol uses ZeppelinOS to manage smart contract upgrades, a keeper contract address might not change over time (because it's just the address _of the proxy contract_) but the actually-used smart contract might change, along with its functionality.
-

+title: Teach Your Wallet to Track Ocean Tokens
+description: How to teach various crypto wallet software to track Ocean Tokens.
+---
+
+If you don't see any Ocean Tokens in your wallet software (e.g. MetaMask or MyEtherWallet), don't worry! It might not know how to track Ocean Tokens yet. You can teach it how.
+
+## Step 1: Determine the Ocean Token Contract Address in the Network You're Using
+
+### Kovan or Nile Testnet
+
+Testnet       | Ocean Token Contract Address
+--------------|-----------------------------
+Kovan         | `0xB57C4D626548eB8AC0B82b086721516493E2908d`
+Nile          | `0xcDae1AFa8025BE03Bc56D112eB4da3277913563d`
+
+If the above addresses are out-of-date, then you can find newer ones in the [keeper-contracts repository on GitHub](https://github.com/oceanprotocol/keeper-contracts):
+
+1. Click on the "Branch: **develop**" button and switch to the tag of the latest release (e.g. `v0.8.6`).
+1. In the `README.md` file, check the address of the OceanToken contract (in Nile or Kovan).
+1. Double-check the address by looking in the file named `zos.kovan.json` (for Kovan) or `zos.dev-8995.json` (for Nile). Check for a block of JSON that looks like:
+
+   ```json
+       "@oceanprotocol/keeper-contracts/OceanToken": [
+         {
+           "address": "0xB57C4D626548eB8AC0B82b086721516493E2908d",
+           "version": "v0.8.6",
+           "implementation": "0x6E2c2D9c1fA947FAE47AD3EFF86A97C0e1E82EE4",
+           "admin": "0xA18999a10D9e7d8116c406D284fa31541e019177"
+         }
+   ```
+
+   Compare the `"address"` value to the value from the `README.md` file.
+
+### Spree or Ganache-Based Testnet
+
+If you're using [Barge](https://github.com/oceanprotocol/barge) to run a local Spree Testnet or a local Ganache-based testnet, then you can get the address of the OceanToken contract by looking at the value of `"address"` in:
+
+- `$HOME/.ocean/keeper-contracts/artifacts/OceanToken.spree.json` for Spree
+- `$HOME/.ocean/keeper-contracts/artifacts/OceanToken.development.json` for Ganache
+
+## Step 2: Teach Your Wallet Software about Ocean Tokens
+
+### MetaMask Instructions
+
+1. Make sure MetaMask is connected to the correct network (Nile, Kovan or whatever). See [the tutorial about how to do that](/tutorials/connect-to-networks/).
+1. For the account you want to manage, click the `☰` (hamburger menu icon).
+1. Scroll down until the `ADD TOKEN` link is visible, then click on it.
+1. Click on `Custom Token`.
+1. Paste the OceanToken contract address (from Step 1 above) into the "Token Contract Address" field. The other two fields should auto-fill. If they don't then something is wrong.
+1. Click `NEXT`.
+1. Click `ADD TOKENS`.
+
+### Other Wallet Software
+
+Do a web search to find out how to add a custom ERC-20 token to the wallet software you're using.
