The blockchain nodes are run as a subprocess of Reader node, can you make that more apparent somehow, either in the diagram or as text information.

Also, replace the gRPC Server By Firehose & Substreams and Load Bal by via gRPC.

Instead of using wide range, let's talk more about any blockchain for which a Firehose enabled node's client exists.

- `--config-file, -c` (string): Configuration file to use (default: `./firehose.yaml`)

### Logging
- `--log-format` (string): Format for logging to stdout (`text` or `stackdriver`, default: `text`)

Remove requirements, simply tell operators to refer to the chain's official documentation they target, Firehose is a dummy reader on top of node's client, so operators should always refer to node's official documentation for how to properly operate the node's client software.

Put Deployment guide before CLI reference.

codegen-sh bot added 4 commits July 18, 2025 13:29
- Remove Getting Started section completely
- Remove Community Integrations section and all community-integration docs
- Remove Integration Template file
- Put Deployment Guide before CLI Reference in SUMMARY.md
- Update architecture diagrams to show nodes as subprocess of Reader
- Replace 'gRPC Server' with 'Firehose & Substreams' in diagrams
- Add GitBook hint about node subprocess relationship

Both guides use dummy-blockchain as chain-agnostic example that can be applied to any Firehose-enabled blockchain.
Single Machine Deployment fixes:
- Add --config-file="" flag to prevent config file conflicts
- Remove incorrect --grpc-listen-addr flag
- Update all port references to correct defaults:
  * Firehose: :10015 (was :9000)
  * Substreams Tier1: :10016 (was :9000)
  * Substreams Tier2: :10017 (was :9000)
- Fix print command syntax:
  * one-blocks → one-block (singular)
  * Remove trailing slashes from paths
  * Use block number 1 instead of 0000000001
- Add comprehensive prerequisites section with port conflict troubleshooting
- Add default ports reference table
- Add protobuf output explanation

Distributed Deployment fixes:
- Add --config-file="" flag to all components
- Fix all print commands (one-blocks → one-block, remove trailing slashes)
- Update all port references to correct defaults:
  * Firehose: :10015 (was :9000)
  * Substreams Tier1: :10016 (was :9001)
  * Substreams Tier2: :10017 (was :9002)
- Fix health check commands with correct ports
- Fix nginx configuration example with correct ports
- Update all gRPC test commands to use correct ports

Both guides now work out-of-the-box with accurate technical details.

No need to create firehose-data, it's automatically created by firecore, find another name for firehose-deployment also as inside there will be firehose-data folder, so it's a bit redundant.
