 @section configuration Configuration
 
 `eosd` uses a REST RPC interface where plugins can register their own endpoints with the API server. This page
 will explain how to use some of the APIs to get information about the blockchain and send transactions.
 
-Before you can query `eosd` you must first enable an API plugin. To do this add the following line to your `config.ini`

+Before you can query `eosd` you must first enable the necessary API plugin(s). Depending on which API you want to enable, add the following line to your `eosd`'s `config.ini`:
 ```
-plugin = eosio::chain_api_plugin
+plugin = eosio::chain_api_plugin // Enable Chain API
+plugin = eosio::wallet_api_plugin // Enable Wallet API
 ```
+Alternatively, for Wallet API, you can also have the wallet functionality separate from `eosd`, by running `eos-walletd` separately.
 
-By default an HTTP server will start on `127.0.0.1:8888`; however, you can also change this with the following configuration line in your `config.ini`:
+For the following guide, we will assume that we have `eosd` running on `127.0.0.1:8888` (Chain API Plugin enabled, Wallet API Plugin disabled) and `eos-walletd` running on `127.0.0.1:8889`.
