-# BlockScout Docker integration
+# BlockScout Docker Integration

-For now this integration is not production ready. It made only for local usage only !
-
-## How to use ?
-First of all, blockscout requires `PostgreSQL` server for working. 
-It will be provided by starting script (new docker image will be created named `postgres`)
-
-**Starting command**
-`make start` - will set everything up and start blockscout in container.
-To connect it to your local environment you will have to configure it using [env variables](#env-variables)
-
-Example connecting to local `ganache` instance running on port `2000` on Mac/Windows:
-```bash
-COIN=DAI \
-ETHEREUM_JSONRPC_VARIANT=ganache \ 
-ETHEREUM_JSONRPC_HTTP_URL=http://host.docker.internal:2000 \
-ETHEREUM_JSONRPC_WS_URL=ws://host.docker.internal:2000 \
-make start
-```
-
-Blockscout will be available on `localhost:4000`
-
-**Note**
-On mac/Windows Docker provides with a special URL `host.docker.internal` that will be available into container and routed to your local machine.
-On Linux docker is starting using `--network=host` and all services should be available on `localhost`
-
-### Migrations
-
-By default, `Makefile` will do migrations for you on `PostgreSQL` creation. 
-But you could run migrations manually using `make migrate` command.
-
-**WARNING** Migrations will clean up your local database !
-
-## Env variables
-
-BlockScout supports 3 different JSON RPC Variants.
-Variant could be configured using `ETHEREUM_JSONRPC_VARIANT` environment variable.
-
-Example: 
-```bash
-ETHEREUM_JSONRPC_VARIANT=ganache make start
-```
-
-Available options are:
-
- * `parity` - Parity JSON RPC (**Default one**)
- * `geth` - Geth JSON RPC
- * `ganache` - Ganache JSON RPC
- 
-
-| Variable | Description | Default value |
-| -------- | ----------- | ------------- |
-| `ETHEREUM_JSONRPC_VARIANT` | Variant of your JSON RPC service: `parity`, `geth` or `ganache` | `parity` |
-| `ETHEREUM_JSONRPC_HTTP_URL` | HTTP JSON RPC URL Only for `geth` or `ganache` variant | Different per JSONRPC variant |
-| `ETHEREUM_JSONRPC_WS_URL` | WS JSON RPC url | Different per JSONRPC variant |
-| `ETHEREUM_JSONRPC_TRACE_URL` | Trace URL **Only for `parity` variant** | `http://localhost:8545` |
-| `COIN` | Default Coin | `POA` |
-| `LOGO` | Coin logo | Empty | 
-| `NETWORK` | Network | Empty |
-| `SUBNETWORK` | Subnetwork | Empty |
-| `NETWORK_ICON` | Network icon | Empty | 
-| `NETWORK_PATH` | Network path | `/` |
-
-
-`ETHEREUM_JSONRPC_HTTP_URL` default values:
-
- * For `parity` - `http://localhost:8545`
- * For `geth` - `https://mainnet.infura.io/8lTvJTKmHPCHazkneJsY`
