-# Bitcoin Core JSON-RPC support
+# `bitcoind` JSON-RPC support
 
 Much of the code in this crate was shamelessy stolen from [rust-bitcoincore-rpc
 v0.19.0](https://github.com/rust-bitcoin/rust-bitcoincore-rpc). As such I have maintained the
 original author's list and added my own name for accountability. All bugs are my own (tcharding).
-
-This is a demo of what may be needed to achieve the following aim:
-
-1. Provide JSON types for some set of Bitcoin Core versions.
-2. Provide a sync client that can be used for integration testing.
-3. Extensively test RPC methods (excl. optional args) for each version of Core we claim to support.
-
-## Client conundrum
-
-- It seems reasonable that `rust-bitcoin` should provide the JSON-RPC types for Bitcoin Core.
-- It seems unreasonable that `rust-bitcoin` should provide a JSON-RPC client.
-- However in order to test the types we have to implement a client.
-
-## Status
-
-- Bitcoin Core `v0.17.1`, `v22.1`, and `v26.1`.
-- RPC methods
-   - `getblockchaininfo`
-   - `getbestblockhash`
-   - `getblock 0`
-   - `getblock 1`
-   - `gettxout`                    <!-- Untested -->
-   - `getnetworkinfo`
-   - `createwallet`
-   - `loadwallet`
-   - `unloadwallet`
-   - `getbalance`
-   - `getbalances`
-   - `getnewaddress`
-   - `generatetoaddress`
-   - `sendtoaddress`
-   - `stop`
