 ## Features
 
- * Supports Electrum protocol [v1.4](https://electrumx-spesmilo.readthedocs.io/en/latest/protocol.html)
- * Maintains an index over transaction inputs and outputs, allowing fast balance queries
- * Fast synchronization of the Bitcoin blockchain (~6.5 hours for ~504GB @ August 2023) using HDD storage.
- * Low index storage overhead (~10%), relying on a local full node for transaction retrieval
- * Efficient mempool tracker (allowing better fee [estimation](https://github.com/spesmilo/electrum/blob/59c1d03f018026ac301c4e74facfc64da8ae4708/RELEASE-NOTES#L34-L46))
- * Low CPU & memory usage (after initial indexing)
- * [`txindex`](https://github.com/bitcoinbook/bitcoinbook/blob/develop/ch03.asciidoc#txindex) is not required for the Bitcoin node
- * Uses a single [RocksDB](https://github.com/spacejam/rust-rocksdb) database, for better consistency and crash recovery

+**Important**: The `Dockerfile` is provided for demonstration purposes and may
+NOT be suitable for production use. The maintainers of electrs are not deeply
+familiar with Docker, so you should DYOR. If you are not familiar with Docker
+either it's probably be safer to NOT use it.
+
+Note: currently Docker installation links statically
+
+Note: health check only works if Prometheus is running on port 4224 inside
+container
+
+```bash
+$ docker build -t electrs-app .
+$ mkdir db
+$ docker run --network host \
+             --volume $HOME/.bitcoin:/home/user/.bitcoin:ro \
+             --volume $PWD/db:/home/user/db \
+             --env ELECTRS_DB_DIR=/home/user/db \
+             --rm -i -t electrs-app
+```
+
+If not using the host-network, you probably want to expose the ports for electrs
+and Prometheus like so:
+
+```bash
+$ docker run --volume $HOME/.bitcoin:/home/user/.bitcoin:ro \
+             --volume $PWD/db:/home/user/db \
+             --env ELECTRS_DB_DIR=/home/user/db \
+             --env ELECTRS_ELECTRUM_RPC_ADDR=0.0.0.0:50001 \
+             --env ELECTRS_MONITORING_ADDR=0.0.0.0:4224 \
+             --rm -i -t electrs-app
+```
+
+To access the server from outside Docker, add `-p 50001:50001 -p 4224:4224` but
+be aware of the security risks. Good practice is to group containers that needs
+access to the server inside the same Docker network and not expose the ports to
+the outside world.
+
+## Docker compose, one step for installation
+
+**NOTE**: This is intend for one step setup with testnet/signet/regnet, inspired
+by [Polar](https://github.com/jamaljsr/polar). **NOT RECOMMAND WITH MAINNET**
+
+To setup testnet, just switch to the [docker](../docker/testnet), and then run:
+
+```bash
+docker compose up -d
+```
+
+If you are not using Docker Desktop, run:
+
+```bash
+docker-compose up -d
+```
+
+The default rpc auth info for bitcoin core is: `alice:alice`, if you want to
+change it, just create a new one with [rpcauth.py](https://github.com/bitcoin/bitcoin/tree/master/share/rpcauth)
+and replace both line 19 in `docker-compose.yml` and line 16 in `electrs.toml`
+with new generated auth info:
+
+```
+-rpcauth=alice:128f22494cc2208ea8376a3d0b45a131$9cc0187c0e49f35454a3ed1250e40ecaef420cfcd294d3ac22496adbe64f04b9
+```
+
+Using it with bitcoin mainnet highly not recommand, use it with you own risk.
+It can not start properly with mainnet by default, you need to generated new rpc
+auth info and modify `docker-compose.yml` and `electrs.toml`.
