 Mempool is the fully featured visualizer, explorer, and API service running on [mempool.space](https://mempool.space/), an open source project developed and operated for the benefit of the Bitcoin community, with a focus on the emerging transaction fee market to help our transition into a multi-layer ecosystem.

 ## Installation Methods
 
@@ -14,17 +14,249 @@ Mempool can be self-hosted on a wide variety of your own hardware, ranging from
 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)
 
+# Docker Installation
+
+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.
+
+## bitcoind only configuration
+
+To run an instance with the default settings, use the following command:
+
+```bash
+$ docker-compose up
+```
+
+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:
+
+```
+rpcuser=mempool
+rpcpassword=mempool
+```
+
+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.

-## Initialization
-
-In an empty dir create 2 sub-dirs
-
-```bash
-mkdir -p data mysql/data mysql/db-scripts
-```
-
-In the `mysql/db-scripts` sub-dir add the `mariadb-structure.sql` file from the mempool repo
-
-Your dir should now look like that:
-
-```bash
-$ls -R
-.:
-data mysql
-
-./data:
-
-./mysql:
-data  db-scripts
-
-./mysql/data:
-
-./mysql/db-scripts:
-mariadb-structure.sql
-```
-
-In the main dir add the following `docker-compose.yml`
-
-```bash

-      MYSQL_USER: "mempool"
-      MYSQL_PASSWORD: "mempool"
-      MYSQL_ROOT_PASSWORD: "admin"
-
-```
-
-You can update all the environment variables inside the API container, especially the RPC and ELECTRUM ones
-
-## Run it
-
-To run our docker-compose use the following cmd:
-
-```bash
-docker-compose up
-```
-
-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-frontend
 
-## Transifex Project
+## Contributing
+
+This package is used for the https://mempool.space, https://liquid.network and https://bisq.markets websites - there are npm scripts to setup all three, which effectively change how BASE_MODULE is  configured:
+
+```
+$ npm run config:defaults:mempool
+$ npm run config:defaults:liquid
+$ npm run config:defaults:bisq
+```
+
+Changes that affect the frontend codebase only can be done using the production backend so you don't need to spin up the entire Mempool infrastructure. This is very convenient in case you want to quickly improve the UI, fix typos or implement new features that don't require any backend changes.
+
+Make your changes, install the project dependencies and run the frontend server as follows:
+
+```
+$ npm install
+$ npm run serve:local-prod
+```
+
+The frontend will be available at http://localhost:4200/ and all API requests will be proxied to the production server at https://mempool.space
+
+After making your changes, you can run our end-to-end automation suite and check for possible regressions:
+
+Headless:
+
+```
+$ npm run config:defaults:mempool && npm run cypress:run
+```
+
+Interactive:
+
+```
+$ npm run config:defaults:mempool && npm run cypress:open
+```
+
+This will open the Cypress test runner, where you can select any of the test files to run.
+
+If all tests are green, submit your PR and it will be reviewed by someone on the team as soon as possible.
