 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.

-./mysql:
-data  db-scripts

-
-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.
