-Mempool is the fully-featured mempool visualizer, explorer, and API service running at [mempool.space](https://mempool.space/). 
+## Installation Methods

-It is an open-source project developed and operated for the benefit of the Bitcoin community, with a focus on the emerging transaction fee market that is evolving Bitcoin into a multi-layer ecosystem.
+Mempool can be self-hosted on a wide variety of your own hardware, ranging from a simple one-click installation on a Raspberry Pi distro, all the way to an advanced high availability cluster of powerful servers for a production instance. We support the following installation methods, ranked in order from simple to advanced:

-# Installation Methods
+1) One-click installation on: [Umbrel](https://github.com/getumbrel/umbrel), [RaspiBlitz](https://github.com/rootzoll/raspiblitz), [RoninDojo](https://code.samourai.io/ronindojo/RoninDojo), or [MyNode](https://github.com/mynodebtc/mynode).
+2) [Docker installation on Linux using docker-compose](https://github.com/mempool/mempool/tree/master/docker)
+3) [Manual installation on Linux or FreeBSD](https://github.com/mempool/mempool#manual-installation)
+4) [Production installation on a powerful FreeBSD server](https://github.com/mempool/mempool/tree/master/production)
+5) [High Availability cluster using powerful FreeBSD servers](https://github.com/mempool/mempool/tree/master/production#high-availability)

-Mempool can be self-hosted on a wide variety of your own hardware, ranging from a simple one-click installation on a Raspberry Pi full-node distro all the way to a robust production instance on a powerful FreeBSD server. 
+# Docker Installation

-**Most people should use a one-click install method.** Other install methods are meant for developers and others with experience managing servers. 
+The `docker` directory contains the Dockerfiles used to build and release the official images and a `docker-compose.yml` file that is intended for end users to run a Mempool instance with minimal effort.

-<a id="one-click-installation"></a>
-## One-Click Installation
+## bitcoind only configuration

-Mempool can be conveniently installed on the following full-node distros: 
- [Umbrel](https://github.com/getumbrel/umbrel)
- [RaspiBlitz](https://github.com/rootzoll/raspiblitz)
- [RoninDojo](https://code.samourai.io/ronindojo/RoninDojo)
- [myNode](https://github.com/mynodebtc/mynode)
- [Start9](https://github.com/Start9Labs/embassy-os)
+To run an instance with the default settings, use the following command:

-**We highly recommend you deploy your own Mempool instance this way.** No matter which option you pick, you'll be able to get your own fully-sovereign instance of Mempool up quickly without needing to fiddle with any settings.
+```bash
+$ docker-compose up
+```

-## Advanced Installation Methods
+The default configuration will allow you to run Mempool using `bitcoind` as the backend, so address lookups will be disabled. It assumes you have added RPC credentials for the `mempool` user with a `mempool` password in your `bitcoin.conf` file:

-Mempool can be installed in other ways too, but we only recommend doing so if you're a developer, have experience managing servers, or otherwise know what you're doing.
+```
+rpcuser=mempool
+rpcpassword=mempool
+```

- See the [`docker/`](./docker/) directory for instructions on deploying Mempool with Docker.
- See the [`backend/`](./backend/) and [`frontend/`](./frontend/) directories for manual install instructions oriented for developers.
- See the [`production/`](./production/) directory for guidance on setting up a more serious Mempool instance designed for high performance at scale.
+If you want to use your current credentials, update them in the `docker-compose.yml` file:
+
+```
+  api:
+    environment:
+      MEMPOOL_BACKEND: "none"
+      RPC_HOST: "172.27.0.1"
+      RPC_PORT: "8332"
+      RPC_USER: "mempool"
+      RPC_PASS: "mempool"
+```
+
+Note: the IP in the example above refers to Docker's default gateway IP address so the container can hit the `bitcoind` instance running on the host machine. If your setup is different, update it accordingly.
+
+You can check if the instance is running by visiting http://localhost - the graphs will be populated as new transactions are detected.
+
+## bitcoind+electrum configuration
+
+In order to run with a `electrum` compatible server as the backend, in addition to the settings required for running with `bitcoind` above, you will need to make the following changes to the `docker-compose.yml` file:
+
+- Under the `api` service, change the value of the `MEMPOOL_BACKEND` key from `none` to `electrum`:
+
+```
+  api:
+    environment:
+      MEMPOOL_BACKEND: "none"
+```
+
+- Under the `api` service, set the `ELECTRUM_HOST` and `ELECTRUM_PORT` keys to your Docker host IP address and set `ELECTRUM_TLS_ENABLED` to `false`:
+
+```
+  api:
+    environment:
+      ELECTRUM_HOST: "172.27.0.1"
+      ELECTRUM_PORT: "50002"
+      ELECTRUM_TLS_ENABLED: "false"
+```
+
+You can update any of the backend settings in the `mempool-config.json` file using the following environment variables to override them under the same `api` `environment` section.

+  Query OK, 0 rows affected (0.00 sec)
+```
+
+## Mempool Backend
+Install mempool dependencies from npm and build the backend:
+
+```bash
+  # backend
+  cd backend
+  npm install --prod
+  npm run build
+```
+
+In the `backend` folder, make a copy of the sample config and modify it to fit your settings.
+
+```bash
+  cp mempool-config.sample.json mempool-config.json
+```
+
+Edit `mempool-config.json` to add your Bitcoin Core node RPC credentials:
+```bash
+{
+  "MEMPOOL": {
+    "NETWORK": "mainnet",
+    "BACKEND": "electrum",

+  }
+}
+```
+
+Start the backend:
+
+```bash
+  npm run start
+```
+
+When it's running you should see output like this:
+
+```bash
+  Mempool updated in 0.189 seconds
+  Updating mempool
+  Mempool updated in 0.096 seconds
+  Updating mempool
+  Mempool updated in 0.099 seconds
+  Updating mempool

+
+```bash
+  sudo rsync -av --delete dist/ /var/www/
+```
+
+## nginx + certbot
+
+Install the supplied nginx.conf and nginx-mempool.conf in /etc/nginx
+
+```bash
+  # install nginx and certbot
+  apt-get install -y nginx python3-certbot-nginx
+
+  # install the mempool configuration for nginx
+  cp nginx.conf nginx-mempool.conf /etc/nginx/
+
+  # replace example.com with your domain name
+  certbot --nginx -d example.com
+
+```
+
+If everything went okay you should see the beautiful mempool :grin:
+
+If you get stuck on "loading blocks", this means the websocket can't connect.
+Check your nginx proxy setup, firewalls, etc. and open an issue if you need help.

-# Mempool Backend
+# Setup backend watchers

-These instructions are mostly intended for developers. 
+The backend is static. Typescript scripts are compiled into the `dist` folder and served through a node web server.

-If you choose to use these instructions for a production setup, be aware that you will still probably need to do additional configuration for your specific OS, environment, use-case, etc. We do our best here to provide a good starting point, but only proceed if you know what you're doing. Mempool only provides support for custom setups to [enterprise sponsors](https://mempool.space/enterprise).
+You can avoid the manual shutdown/recompile/restart command line cycle by using a watcher.

-See other ways to set up Mempool on [the main README](/../../#installation-methods).
+Make sure you are in the `backend` directory `cd backend`.

-Jump to a section in this doc:
- [Set Up the Backend](#setup)
- [Development Tips](#development-tips)
-
-## Setup
-
-### 1. Clone Mempool Repository
-
-Get the latest Mempool code:
+1. Install nodemon and ts-node

 ```
-git clone https://github.com/mempool/mempool
-cd mempool
+sudo npm install -g ts-node nodemon
 ```

-Check out the latest release:
+2. Run the watcher
+
+> Note: You can find your npm global binary folder using `npm -g bin`, where nodemon will be installed.

 ```
-latestrelease=$(curl -s https://api.github.com/repos/mempool/mempool/releases/latest|grep tag_name|head -1|cut -d '"' -f4)
-git checkout $latestrelease
+nodemon src/index.ts --ignore cache/ --ignore pools.json
 ```

-### 2. Configure Bitcoin Core
-
-Turn on `txindex`, enable RPC, and set RPC credentials in `bitcoin.conf`:
-
-```
-txindex=1
-server=1
-rpcuser=mempool
-rpcpassword=mempool
-```
-
-### 3. Configure Electrum Server
-
-[Pick an Electrum Server implementation](https://mempool.space/docs/faq#address-lookup-issues), configure it, and make sure it's synced.
-
-**This step is optional.** You can run Mempool without configuring an Electrum Server for it, but address lookups will be disabled.
-
-### 4. Configure MariaDB
-
-_Mempool needs MariaDB v10.5 or later. If you already have MySQL installed, make sure to migrate any existing databases **before** installing MariaDB._
-
-Get MariaDB from your operating system's package manager:
-
-```
-# Debian, Ubuntu, etc.
-apt-get install mariadb-server mariadb-client
-
-# macOS
-brew install mariadb
-mysql.server start
-```
-
-Create a database and grant privileges:
-
-```
-MariaDB [(none)]> drop database mempool;
-Query OK, 0 rows affected (0.00 sec)
-
-MariaDB [(none)]> create database mempool;
-Query OK, 1 row affected (0.00 sec)
-
-MariaDB [(none)]> grant all privileges on mempool.* to 'mempool'@'%' identified by 'mempool';
-Query OK, 0 rows affected (0.00 sec)
-```
-
-### 5. Prepare Mempool Backend
-
-#### Build
-
-_Make sure to use Node.js 16.10 and npm 7._
-
-_The build process requires [Rust](https://www.rust-lang.org/tools/install) to be installed._
-
-Install dependencies with `npm` and build the backend:
-
-```
-cd backend
-npm install
-npm run build
-```
-
-#### Configure
-
-In the backend folder, make a copy of the sample config file:
-
-```
-cp mempool-config.sample.json mempool-config.json
-```
-
-Edit `mempool-config.json` as needed. 
-
-In particular, make sure:
- the correct Bitcoin Core RPC credentials are specified in `CORE_RPC`
- the correct `BACKEND` is specified in `MEMPOOL`:
-  - "electrum" if you're using [romanz/electrs](https://github.com/romanz/electrs) or [cculianu/Fulcrum](https://github.com/cculianu/Fulcrum)
-  - "esplora" if you're using [Blockstream/electrs](https://github.com/Blockstream/electrs)
-  - "none" if you're not using any Electrum Server
-
-### 6. Run Mempool Backend
-
-Run the Mempool backend:
-
-```
-npm run start
-
-```
-You can also set env var `MEMPOOL_CONFIG_FILE` to specify a custom config file location:
-```
-MEMPOOL_CONFIG_FILE=/path/to/mempool-config.json npm run start
-```
-
-When it's running, you should see output like this:
-
-```
-Mempool updated in 0.189 seconds
-Updating mempool
-Mempool updated in 0.096 seconds
-Updating mempool
-Mempool updated in 0.099 seconds
-Updating mempool
-Calculated fee for transaction 1 / 10
-Calculated fee for transaction 2 / 10
-Calculated fee for transaction 3 / 10
-Calculated fee for transaction 4 / 10
-Calculated fee for transaction 5 / 10
-Calculated fee for transaction 6 / 10
-Calculated fee for transaction 7 / 10
-Calculated fee for transaction 8 / 10
-Calculated fee for transaction 9 / 10
-Calculated fee for transaction 10 / 10
-Mempool updated in 0.243 seconds
-Updating mempool
-```
-
-### 7. Set Up Mempool Frontend
-With the backend configured and running, proceed to set up the [Mempool frontend](../frontend#manual-setup).
-
-## Development Tips
-
-### Set Up Backend Watchers
-
-The Mempool backend is static. TypeScript scripts are compiled into the `dist` folder and served through a Node.js web server. 
-
-As a result, for development purposes, you may find it helpful to set up backend watchers to avoid the manual shutdown/recompile/restart command-line cycle.
-
-First, install `nodemon` and `ts-node`:
-
-```
-npm install -g ts-node nodemon
-```
-
-Then, run the watcher:
-
-```
-nodemon src/index.ts --ignore cache/
-```
-
-`nodemon` should be in npm's global binary folder. If needed, you can determine where that is with `npm -g bin`.
-
-### Useful Regtest Commands
-
-Helpful link: https://gist.github.com/System-Glitch/cb4e87bf1ae3fec9925725bb3ebe223a
-
-Run bitcoind on regtest:
-   ```
-   bitcoind -regtest
-   ```
-
-Create a new wallet, if needed:
-   ```
-   bitcoin-cli -regtest createwallet test
-   ```
-
-Load wallet (this command may take a while if you have lot of UTXOs):
-   ```
-   bitcoin-cli -regtest loadwallet test
-   ```
-
-Get a new address:
-   ```
-   address=$(bitcoin-cli -regtest getnewaddress)
-   ```
-
-Mine blocks to the previously generated address. You need at least 101 blocks before you can spend. This will take some time to execute (~1 min):
-   ```
-   bitcoin-cli -regtest generatetoaddress 101 $address
-   ```
-
-Send 0.1 BTC at 5 sat/vB to another address:
-   ```
-   bitcoin-cli -named -regtest sendtoaddress address=$(bitcoin-cli -regtest getnewaddress) amount=0.1 fee_rate=5
-   ```
-
-See more example of `sendtoaddress`:
-   ```
-   bitcoin-cli sendtoaddress # will print the help
-   ```
-
-Mini script to generate random network activity (random TX count with random tx fee-rate). It's slow so don't expect to use this to test mempool spam, except if you let it run for a long time, or maybe with multiple regtest nodes connected to each other.
-   ```
-   #!/bin/bash
-   address=$(bitcoin-cli -regtest getnewaddress)
-   bitcoin-cli -regtest generatetoaddress 101 $address
-   for i in {1..1000000}
-   do
-      for y in $(seq 1 "$(jot -r 1 1 1000)")
-      do
-         bitcoin-cli -regtest -named sendtoaddress address=$address amount=0.01 fee_rate=$(jot -r 1 1 100)
-      done
-      bitcoin-cli -regtest generatetoaddress 1 $address
-      sleep 5
-   done
-   ```
-
-Generate block at regular interval (every 10 seconds in this example):
-   ```
-   watch -n 10 "bitcoin-cli -regtest generatetoaddress 1 $address"
-   ```
-
-### Mining pools update
-
-By default, mining pools will be not automatically updated regularly (`config.MEMPOOL.AUTOMATIC_BLOCK_REINDEXING` is set to `false`). 
-
-To manually update your mining pools, you can use the `--update-pools` command line flag when you run the nodejs backend. For example `npm run start --update-pools`. This will trigger the mining pools update and automatically re-index appropriate blocks.
-
-You can enabled the automatic mining pools update by settings `config.MEMPOOL.AUTOMATIC_BLOCK_REINDEXING` to `true` in your `mempool-config.json`.
-
-When a `coinbase tag` or `coinbase address` change is detected, all blocks tagged to the `unknown` mining pools (starting from height 130635) will be deleted from the `blocks` table. Additionaly, all blocks which were tagged to the pool which has been updated will also be deleted from the `blocks` table. Of course, those blocks will be automatically reindexed.
-
-### Re-index tables
-
-You can manually force the nodejs backend to drop all data from a specified set of tables for future re-index. This is mostly useful for the mining dashboard and the lightning explorer.
-
-Use the `--reindex` command to specify a list of comma separated table which will be truncated at start. Note that a 5 seconds delay will be observed before truncating tables in order to give you a chance to cancel (CTRL+C) in case of misuse of the command.
-
-Usage:
-```
-npm run start --reindex=blocks,hashrates
-```
-Example output:
-```
-Feb 13 14:55:27 [63246] WARN: <lightning> Indexed data for "hashrates" tables will be erased in 5 seconds (using '--reindex')
-Feb 13 14:55:32 [63246] NOTICE: <lightning> Table hashrates has been truncated
-```

-# gbt
-
-**gbt:** rust implementation of the getBlockTemplate algorithm
-
-This project was bootstrapped by [napi](https://www.npmjs.com/package/@napi-rs/cli).
-
-## Installing gbt
-
-Installing gbt requires a [supported version of Node and Rust](https://github.com/napi-rs/napi-rs#platform-support).
-
-The build process also requires [Rust](https://www.rust-lang.org/tools/install) to be installed.
-
-You can install the project with npm. In the project directory, run:
-
-```sh
-$ npm install
-```
-
-This fully installs the project, including installing any dependencies and running the build.
-
-## Building gbt
-
-If you have already installed the project and only want to run the build, run:
-
-```sh
-$ npm run build
-```
-
-This command uses the [napi build](https://www.npmjs.com/package/@napi-rs/cli) utility to run the Rust build and copy the built library into `./gbt.[TARGET_TRIPLE].node`.
-
-## Exploring gbt
-
-After building gbt, you can explore its exports at the Node REPL:
-
-```sh
-$ npm install
-$ node
-> require('.').hello()
-"hello node"
-```
-
-## Available Scripts
-
-In the project directory, you can run:
-
-### `npm install`
-
-Installs the project, including running `npm run build-release`.
-
-### `npm build`
-
-Builds the Node addon (`gbt.[TARGET_TRIPLE].node`) from source.
-
-Additional [`cargo build`](https://doc.rust-lang.org/cargo/commands/cargo-build.html) arguments may be passed to `npm build` and `npm build-*` commands. For example, to enable a [cargo feature](https://doc.rust-lang.org/cargo/reference/features.html):
-
-```
-npm run build -- --feature=beetle
-```
-
-#### `npm build-debug`
-
-Alias for `npm build`.
-
-#### `npm build-release`
-
-Same as [`npm build`](#npm-build) but, builds the module with the [`release`](https://doc.rust-lang.org/cargo/reference/profiles.html#release) profile. Release builds will compile slower, but run faster.
-
-### `npm test`
-
-Runs the unit tests by calling `cargo test`. You can learn more about [adding tests to your Rust code](https://doc.rust-lang.org/book/ch11-01-writing-tests.html) from the [Rust book](https://doc.rust-lang.org/book/).

-### Cargo.toml
-
-The Cargo [manifest file](https://doc.rust-lang.org/cargo/reference/manifest.html), which informs the `cargo` command.
-
-### README.md
-
-This file.
-
-### gbt.\[TARGET_TRIPLE\].node
-
-The Node addon—i.e., a binary Node module—generated by building the project. This is the main module for this package, as dictated by the `"main"` key in `package.json`.
-
-Under the hood, a [Node addon](https://nodejs.org/api/addons.html) is a [dynamically-linked shared object](https://en.wikipedia.org/wiki/Library_(computing)#Shared_libraries). The `"build"` script produces this file by copying it from within the `target/` directory, which is where the Rust build produces the shared object.
-
-### package.json
-
-The npm [manifest file](https://docs.npmjs.com/cli/v7/configuring-npm/package-json), which informs the `npm` command.
-
-### src/
-
-The directory tree containing the Rust source code for the project.
-
-### src/lib.rs
-
-The Rust library's main module.
-
-### target/
-
-Binary artifacts generated by the Rust build.
