-btcd is an alternative full node bitcoin implementation written in Go (golang).
+lbcd is a full node implementation of LBRY's blockchain written in Go (golang).
 
-This project is currently under active development and is in a Beta state.  It
-is extremely stable and has been in production use since October 2013.
+This project is currently under active development and is in a Beta state while we 
+ensure it matches LBRYcrd's functionality. The intention is that it properly downloads, validates, and serves the block chain using the exact
+rules (including consensus bugs) for block acceptance as LBRYcrd.  We have
+taken great care to avoid lbcd causing a fork to the blockchain.
 
-It properly downloads, validates, and serves the block chain using the exact
-rules (including consensus bugs) for block acceptance as Bitcoin Core.  We have
-taken great care to avoid btcd causing a fork to the block chain.  It includes a
-full block validation testing framework which contains all of the 'official'
-block acceptance tests (and some additional ones) that is run on every pull
-request to help ensure it properly follows consensus.  Also, it passes all of
-the JSON test data in the Bitcoin Core code.
+Note: lbcd does *NOT* include
+wallet functionality.  That functionality is provided by the
+[lbcwallet](https://github.com/lbryio/lbcwallet) and the [LBRY SDK](https://github.com/lbryio/lbry-sdk).
 
-It also properly relays newly mined blocks, maintains a transaction pool, and
-relays individual transactions that have not yet made it into a block.  It
-ensures all individual transactions admitted to the pool follow the rules
-required by the block chain and also includes more strict checks which filter
-transactions based on miner requirements ("standard" transactions).
+## Security
 
-One key difference between btcd and Bitcoin Core is that btcd does *NOT* include
-wallet functionality and this was a very intentional design decision.  See the
-blog entry [here](https://web.archive.org/web/20171125143919/https://blog.conformal.com/btcd-not-your-moms-bitcoin-daemon)
-for more details.  This means you can't actually make or receive payments
-directly with btcd.  That functionality is provided by the
-[btcwallet](https://github.com/btcsuite/btcwallet) and
-[Paymetheus](https://github.com/btcsuite/Paymetheus) (Windows-only) projects
-which are both under active development.
+We take security seriously. Please contact [security](mailto:security@lbry.com) regarding any security issues.
+Our PGP key is [here](https://lbry.com/faq/pgp-key) if you need it.
+
+We maintain a mailing list for notifications of upgrades, security issues,
+and soft/hard forks. To join, visit https://lbry.com/forklist
 
 ## Requirements
 
-[Go](http://golang.org) 1.14 or newer.
+All common operating systems are supported. lbcd requires at least 8GB of RAM 
+and at least 100GB of disk storage. Both RAM and disk requirements increase slowly over time. 
+Using a fast NVMe disk is recommended.
+
+lbcd is not immune to data loss. It expects a clean shutdown 
+via SIGINT or SIGTERM. SIGKILL, immediate VM kills, and sudden power loss 
+can cause data corruption, thus requiring chain resynchronization for recovery.
+
+For compilation, [Go](http://golang.org) 1.16 or newer is required. 
 
 ## Installation
 
-https://github.com/btcsuite/btcd/releases
+Acquire binary files from https://github.com/lbryio/lbcd/releases
 
-#### Linux/BSD/MacOSX/POSIX - Build from Source
+#### To build from Source on Linux/BSD/MacOSX/POSIX:
 
-- Install Go according to the installation instructions here:
-  http://golang.org/doc/install
+- Install Go according to its [installation instructions](http://golang.org/doc/install).
+- Use your favorite git tool to acquire the lbcd source.  
+- lbcd has no non-Go dependencies; it can be built by simply running `go build .`
+- lbcctl can be built similarly: 
 
-- Ensure Go was installed properly and is a supported version:
+Both [GoLand](https://www.jetbrains.com/go/) 
+and [VS Code](https://code.visualstudio.com/docs/languages/go) IDEs are supported.
 
-```bash
-$ go version
-$ go env GOROOT GOPATH
+## Usage
+
+By default, data and logs are stored in `~/.lbcd/`
+
+To enable RPC access a username and password is required. Example: 
 ```
-
-NOTE: The `GOROOT` and `GOPATH` above must not be the same path.  It is
-recommended that `GOPATH` is set to a directory in your home directory such as
-`~/goprojects` to avoid write permission issues.  It is also recommended to add
-`$GOPATH/bin` to your `PATH` at this point.
-
-- Run the following commands to obtain btcd, all dependencies, and install it:
-
-```bash
-$ cd $GOPATH/src/github.com/btcsuite/btcd
-$ GO111MODULE=on go install -v . ./cmd/...
+./lbcd --notls --rpcuser=x --rpcpass=y --txindex &
+./lbcctl --notls --rpcuser=x --rpcpass=y getblocktemplate
 ```
+<!-- TODO: explain how to use TLS certificates. -->
 
-- btcd (and utilities) will now be installed in ```$GOPATH/bin```.  If you did
-  not already add the bin directory to your system path during Go installation,
-  we recommend you do so now.

-## Examples
-
-* [ProcessBlock Example](https://pkg.go.dev/github.com/btcsuite/btcd/blockchain#example-BlockChain-ProcessBlock)  
-  Demonstrates how to create a new chain instance and use ProcessBlock to
-  attempt to add a block to the chain.  This example intentionally

-  block is handled.
-
-* [CompactToBig Example](https://pkg.go.dev/github.com/btcsuite/btcd/blockchain#example-CompactToBig)  
-  Demonstrates how to convert the compact "bits" in a block header which

-verify the signature perform the following:
-
-- Download the public key from the Conformal website at
-  https://opensource.conformal.com/GIT-GPG-KEY-conformal.txt
-
-- Import the public key into your GPG keyring:
-  ```bash
-  gpg --import GIT-GPG-KEY-conformal.txt
-  ```
-
-- Verify the release tag with the following command where `TAG_NAME` is a
-  placeholder for the specific tag:
-  ```bash
-  git tag -v TAG_NAME

 Bitcoin (secp256k1 only for now). It is designed so that it may be used with the
 standard crypto/ecdsa packages provided with go.  A comprehensive suite of test
 is provided to ensure proper functionality.  Package btcec was originally based
 on work from ThePiachu which is licensed under the same terms as Go, but it has
-signficantly diverged since then.  The btcsuite developers original is licensed
-under the liberal ISC license.

 Package btcjson implements concrete types for marshalling to and from the
 bitcoin JSON-RPC API.  A comprehensive suite of tests is provided to ensure
 proper functionality.
-
-Although this package was primarily written for the btcsuite, it has
-intentionally been designed so it can be used as a standalone package for any
-projects needing to marshal to and from bitcoin JSON-RPC requests and responses.
-
-Note that although it's possible to use this package directly to implement an
-RPC client, it is not recommended since it is only intended as an infrastructure
-package.  Instead, RPC clients should use the
-[btcrpcclient](https://github.com/btcsuite/btcrpcclient) package which provides
-a full blown RPC client with many features such as automatic connection
-management, websocket support, automatic notification re-registration on
-reconnect, and conversion from the raw underlying RPC types (strings, floats,
-ints, etc) to higher-level types with many nice and useful properties.

-## Examples

-* [Marshal Command](https://pkg.go.dev/github.com/btcsuite/btcd/btcjson#example-MarshalCmd)  
-  Demonstrates how to create and marshal a command into a JSON-RPC request.
-
-* [Unmarshal Command](https://pkg.go.dev/github.com/btcsuite/btcd/btcjson#example-UnmarshalCmd)  
-  Demonstrates how to unmarshal a JSON-RPC request and then unmarshal the
-  concrete request into a concrete command.
-
-* [Marshal Response](https://pkg.go.dev/github.com/btcsuite/btcd/btcjson#example-MarshalResponse)  
-  Demonstrates how to marshal a JSON-RPC response.

 Package chaincfg defines chain configuration parameters for the three standard
-Bitcoin networks and provides the ability for callers to define their own custom
-Bitcoin networks.
-
-Although this package was primarily written for btcd, it has intentionally been
-designed so it can be used as a standalone package for any projects needing to
-use parameters for the standard Bitcoin networks or for projects needing to
-define their own network.
-
-## Sample Use
-
-```Go
-package main
-
-import (
-	"flag"
-	"fmt"
-	"log"
-
-	"github.com/btcsuite/btcutil"
-	"github.com/btcsuite/btcd/chaincfg"
-)
-
-var testnet = flag.Bool("testnet", false, "operate on the testnet Bitcoin network")
-
-// By default (without -testnet), use mainnet.
-var chainParams = &chaincfg.MainNetParams
-
-func main() {
-	flag.Parse()
-
-	// Modify active network parameters if operating on testnet.
-	if *testnet {
-		chainParams = &chaincfg.TestNet3Params
-	}
-
-	// later...
-
-	// Create and print new payment address, specific to the active network.
-	pubKeyHash := make([]byte, 20)
-	addr, err := btcutil.NewAddressPubKeyHash(pubKeyHash, chainParams)
-	if err != nil {
-		log.Fatal(err)
-	}
-	fmt.Println(addr)
-}
-```
-
-## Installation and Updating
-
-```bash
-$ go get -u github.com/btcsuite/btcd/chaincfg
-```
-
-## GPG Verification Key
-
-All official release tags are signed by Conformal so users can ensure the code
-has not been tampered with and is coming from the btcsuite developers.  To
-verify the signature perform the following:
-
-- Download the public key from the Conformal website at
-  https://opensource.conformal.com/GIT-GPG-KEY-conformal.txt
-
-- Import the public key into your GPG keyring:
-  ```bash
-  gpg --import GIT-GPG-KEY-conformal.txt
-  ```
-
-- Verify the release tag with the following command where `TAG_NAME` is a
-  placeholder for the specific tag:
-  ```bash
-  git tag -v TAG_NAME
-  ```
