-### 1. Overview
-
-btcd provides a [JSON-RPC](http://json-rpc.org/wiki/specification) API that is
-fully compatible with the original bitcoind/bitcoin-qt. There are a few key
-differences between btcd and bitcoind as far as how RPCs are serviced:
-* Unlike bitcoind that has the wallet and chain intermingled in the same process
- which leads to several issues, btcd intentionally splits the wallet and chain
- services into independent processes. See the blog post
- [here](https://blog.conformal.com/btcd-not-your-moms-bitcoin-daemon/) for
- further details on why they were separated. This means that if you are
- talking directly to btcd, only chain-related RPCs are available. However both
- chain-related and wallet-related RPCs are available via
- [btcwallet](https://github.com/btcsuite/btcwallet).
-* btcd is secure by default which means that the RPC connection is TLS-enabled
- by default
-* btcd provides access to the API through both
- [HTTP POST](http://en.wikipedia.org/wiki/POST_%28HTTP%29) requests and
- [Websockets](http://en.wikipedia.org/wiki/WebSocket)
-
-Websockets are the preferred transport for btcd RPC and are used by applications
-such as [btcwallet](https://github.com/btcsuite/btcwallet) for inter-process
-communication with btcd. The websocket connection endpoint for btcd is
-`wss://your_ip_or_domain:8334/ws`.
-
-In addition to the [standard API](#Methods), an [extension API](#WSExtMethods)
-has been developed that is exclusive to clients using Websockets. In its current
-state, this API attempts to cover features found missing in the standard API
-during the development of btcwallet.
-
-While the [standard API](#Methods) is stable, the
-[Websocket extension API](#WSExtMethods) should be considered a work in
-progress, incomplete, and susceptible to changes (both additions and removals).
-
-The original bitcoind/bitcoin-qt JSON-RPC API documentation is available at [https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_Calls_list](https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_Calls_list)
-
-<a name="HttpPostVsWebsockets" />
-
-### 2. HTTP POST Versus Websockets
-
-The btcd RPC server supports both [HTTP POST](http://en.wikipedia.org/wiki/POST_%28HTTP%29)
-requests and the preferred [Websockets](http://en.wikipedia.org/wiki/WebSocket).
-All of the [standard](#Methods) and [extension](#ExtensionMethods) methods
-described in this documentation can be accessed through both. As the name
-indicates, the [Websocket-specific extension](#WSExtMethods) methods can only be
-accessed when connected via Websockets.
-
-As mentioned in the [overview](#Overview), the websocket connection endpoint for
-btcd is `wss://your_ip_or_domain:8334/ws`.
-
-The most important differences between the two transports as it pertains to the
-JSON-RPC API are:
-
-| |HTTP POST Requests|Websockets|
-|---|------------------|----------|
-|Allows multiple requests across a single connection|No|Yes|
-|Supports asynchronous notifications|No|Yes|
-|Scales well with large numbers of requests|No|Yes|
-
-<a name="Authentication" />
-
-### 3. Authentication
-
-<a name="AuthenticationOverview" />
-
-**3.1 Authentication Overview**<br />
-
-The following authentication details are needed before establishing a connection
-to a btcd RPC server:
-
-* **rpcuser** is the full-access username configured for the btcd RPC server
-* **rpcpass** is the full-access password configured for the btcd RPC server
-* **rpclimituser** is the limited username configured for the btcd RPC server
-* **rpclimitpass** is the limited password configured for the btcd RPC server
-* **rpccert** is the PEM-encoded X.509 certificate (public key) that the btcd
- server is configured with. It is automatically generated by btcd and placed
- in the btcd home directory (which is typically `%LOCALAPPDATA%\Btcd` on
- Windows and `~/.btcd` on POSIX-like OSes)
-
-**NOTE:** As mentioned above, btcd is secure by default which means the RPC
-server is not running unless configured with a **rpcuser** and **rpcpass**
-and/or a **rpclimituser** and **rpclimitpass**, and uses TLS authentication for
-all connections.
-
-Depending on which connection transaction you are using, you can choose one of
-two, mutually exclusive, methods.
-- [Use HTTP Authorization Header](#HTTPAuth) - HTTP POST requests and Websockets
-- [Use the JSON-RPC "authenticate" command](#JSONAuth) - Websockets only
-
-<a name="HTTPAuth" />
-
-**3.2 HTTP Basic Access Authentication**<br />
-
-The btcd RPC server uses HTTP [basic access authentication](http://en.wikipedia.org/wiki/Basic_access_authentication) with the **rpcuser**
-and **rpcpass** detailed above. If the supplied credentials are invalid, you
-will be disconnected immediately upon making the connection.
-
-<a name="JSONAuth" />
-
-**3.3 JSON-RPC Authenticate Command (Websocket-specific)**<br />
-
-While the HTTP basic access authentication method is the preferred method, the
-ability to set HTTP headers from websockets is not always available. In that
-case, you will need to use the [authenticate](#authenticate) JSON-RPC method.
-
-The [authenticate](#authenticate) command must be the first command sent after
-connecting to the websocket. Sending any other commands before authenticating,
-supplying invalid credentials, or attempting to authenticate again when already
-authenticated will cause the websocket to be closed immediately.
-
-
-<a name="CLIUtil" />
-
-### 4. Command-line Utility
-
-btcd comes with a separate utility named `btcctl` which can be used to issue
-these RPC commands via HTTP POST requests to btcd after configuring it with the
-information in the [Authentication](#Authentication) section above. It can also
-be used to communicate with any server/daemon/service which provides a JSON-RPC
-API compatible with the original bitcoind/bitcoin-qt client.

-|Description|Verifies the block chain database.<br />The actual checks performed by the `checklevel` parameter is implementation specific. For btcd this is:<br />`checklevel=0` - Look up each block and ensure it can be loaded from the database.<br />`checklevel=1` - Perform basic context-free sanity checks on each block.|
-|Notes|<font color="orange">Btcd currently only supports `checklevel` 0 and 1, but the default is still 3 for compatibility. Per the information in the Parameters section above, higher levels are automatically clamped to the highest supported level, so this means the default is effectively 1 for btcd.</font>|

-### 8. Notifications (Websocket-specific)
-
-btcd uses standard JSON-RPC notifications to notify clients of changes, rather than requiring clients to poll btcd for updates. JSON-RPC notifications are a subset of requests, but do not contain an ID. The notification type is categorized by the `method` field and additional details are sent as a JSON array in the `params` field.

-
-The following is an example Go application which uses the

-a btcd instance via Websockets, issues [getblockcount](#getblockcount) to
-retrieve the current block height, and displays it.
-
-```Go
-package main

- "github.com/btcsuite/btcrpcclient"
- "github.com/btcsuite/btcutil"
- "io/ioutil"
- "log"
- "path/filepath"

- // Load the certificate for the TLS connection which is automatically
- // generated by btcd when it starts the RPC server and doesn't already
- // have one.
- btcdHomeDir := btcutil.AppDataDir("btcd", false)
- certs, err := ioutil.ReadFile(filepath.Join(btcdHomeDir, "rpc.cert"))
- if err != nil {

-**9.2.1 Using notifyblocks to be Notified of Block Connects and Disconnects**<br />
-
-The following is example node.js code which uses [ws](https://github.com/einaros/ws)
-(can be installed with `npm install ws`) to connect with a btcd instance,
-issues [notifyblocks](#notifyblocks) to register for
-[blockconnected](#blockconnected) and [blockdisconnected](#blockdisconnected)
-notifications, and displays all incoming messages.
-
-```javascript
-var fs = require('fs');
-var WebSocket = require('ws');
-
-// Load the certificate for the TLS connection which is automatically
-// generated by btcd when it starts the RPC server and doesn't already
-// have one.
-var cert = fs.readFileSync('/path/to/btcd/appdata/rpc.cert');
-var user = "yourusername";
-var password = "yourpassword";
-
-
-// Initiate the websocket connection. The btcd generated certificate acts as
-// its own certificate authority, so it needs to be specified in the 'ca' array
-// for the certificate to properly validate.
-var ws = new WebSocket('wss://127.0.0.1:8334/ws', {
- headers: {
- 'Authorization': 'Basic '+new Buffer(user+':'+password).toString('base64')

- // Send a JSON-RPC command to be notified when blocks are connected and
- // disconnected from the chain.
- ws.send('{"jsonrpc":"1.0","id":"0","method":"notifyblocks","params":[]}');
-});
-ws.on('message', function(data, flags) {
