 # Api3ReaderProxyV1
 
-Api3ReaderProxyV1 is the [proxy](../../../glossary.md#proxy) that should be used to read API3 [dAPIs](../../../glossary.md#dapi).
+Api3ReaderProxyV1 is an upgradeable [proxy](../../../glossary.md#proxy) that should be used to read API3 [dAPIs](../../../glossary.md#dapi).
 It implements [IApi3ReaderProxy](../../interfaces/iapi3readerproxy.md) as a first-class citizen, and partially implements Chainlink's AggregatorV2V3Interface for convenience (refer to https://github.com/api3dao/migrate-from-chainlink-to-api3 for more information about the latter).
 
 Api3ReaderProxyV1 is a UUPS-upgradeable proxy with a proxy-specific implementation.

 # ExtendedSelfMulticall
+
+ExtendedSelfMulticall is an extended version of [SelfMulticall](./selfmulticall.md).
+It allows the caller to query some account and block properties, which are specifically added to minimize [Airseeker](../../glossary.md#airseeker) RPC calls.

 # SelfMulticall
+
+There are two popular multicall contracts out there:
+
+- OpenZeppelin's Multicall is inherited by a contract to enable senders to batch their calls
+- MakerDAO's Multicall is a standalone contract that enable callers to batch their reads
+
+SelfMulticall's main purpose is similar to OpenZeppelin's Multicall, in that it is meant to be inherited by a contract to enable batched calls without affecting `msg.sender`.
+However, it implements an additional `tryMulticall()` function similar to the `try...()` functions of MakerDAO's Multicall, which does not require all batched calls to succeed.
+
+SelfMulticall also has an extended version, [ExtendedSelfMulticall](./extendedselfmulticall.md), which allows the caller to query some account and block properties.
+
+## Reading
+
+For a batch read operation, one should use `tryMulticall()` to receive a best effort response.
+If all calls are guaranteed to succeed, `multicall()` can also be used instead.
+
+## Writing
+
+For a batch send operation, one should
+
+- Make a `tryMulticall()` call with the array of calldata
+- Filter out the calldata that fail
+- Make an `eth_estimateGas` call for `multicall()` with the filtered array of calldata
+- Send the transaction that calls `tryMulticall()` with the filtered array of calldata, using the gas amount returned from the previous step (+10% headroom for the potential difference between `multicall()` and `tryMulticall()`, which is overkill)
+
+The above assumes that some calldata from the array may fail consistently, and some may fail at runtime.
+If all calldata are guaranteed to succeed due to how the target contract is implemented, one can send the transaction with `multicall()` directly, without going through any of these steps.
