-# Subtreams packages
+# Substreams Indexing Integrations
 
-This directory contains all substream packages that are used to index integrated protocols across different blockchains.
+Please refer to the official [Substreams Indexing](https://app.gitbook.com/o/9wMvRDQIhk1xOsIZ0Zde/s/Yx9kvxtpT2xWdzvFiB3t/indexing/substreams-integration) docs.
 
-## Adding a new package
+## Release
 
-To add a new package add a folder. The naming convention is `[CHAIN]-[PROTOCOL_SYSTEM]`. 
+To release a package simply tag a commit with the package name and its version: 
+e.g. `ethereum-balancer-0.1.0`. This will create a release and automatically build 
+and push the spkg into our registry.
 
-### Manifest
-In this new folder add a manifest file `substreams.yaml`. You can use the template below to get started:
+### Note
+The CD pipeline will error if the Cargo version is not the same as the version in 
+the tag.
 
-```yaml
-specVersion: v0.1.0
-package:
-  name: 'substreams_[CHAIN]_[PROTOCOL_SYSTEM]'
-  version: v0.1.0
+Releases are immutable so do no try to delete tags or build the same release twice 
+since this will error.
 
-protobuf:
-  files:
-    - vm.proto
-    - common.proto
-    # You can specify any internal proto files here
-  importPaths:
-    - ../../proto/tycho/evm/v1/
-    # Any private message types only used in internal modules 
-    # can remain local to the folder.
-    - ./proto
+### Pre release
 
-binaries:
-  default:
-    type: wasm/rust-v1
-    # this points to the workspace target directory we use a special 
-    # substreams build profile to optimise wasm binaries
-    file: ../../target/wasm32-unknown-unknown/substreams/substreams_[CHAIN]_[PROTOCOL_SYSTEM].wasm
+To create a pre release for testing in dev you can start CD pipeline manually supplying 
+the package you'd like to pre release. This will create a 
+`[package]-[semver].pre-[commit-sha]` release in our spkg repository which you can use 
+to run the substream´.
 
-modules:
-  - name: map_changes
-    kind: map
-    inputs:
-      - source: sf.ethereum.type.v2.Block
-    output:
-      type: proto:tycho.evm.state.v1.BlockContractChanges

-Substreams packages are Rust crates so we also need a `cargo.toml`.
-The example from the official docs will serve us just well:
-
-```toml
-[package]
-name = "substreams-[CHAIN]-[PROTOCOL_SYSTEM]"
-version = "0.1.0"
-edition = "2021"
-
-[lib]
-name = "substreams_[CHAIN]_[PROTOCOL_SYSTEM]"
-crate-type = ["cdylib"]
-
-[dependencies]
-substreams = "0.5"
-substreams-ethereum = "0.9"
-prost = "0.11"
-
-```
-
-There are already some generated rust files in the `src/pb` directory. These are generated 
-from the protobuf files in the `/proto/tycho/evm/v1` directory. They specify the output protobuf messages
-we want to generate. The input Block is specified by the subtreams crate, specifically the [sf.ethereum.type.v2.Block](https://github.com/streamingfast/substreams-ethereum/blob/develop/core/src/pb/sf.ethereum.type.v2.rs) message.
-
-You can define your own protobuf messages, make a new directory `/substreams/[CHAIN]-[PROTOCOL]/proto` for them.
-
-
-Now we can generate the Rust protobuf code:
-
-```
-substreams protogen substreams.yaml --exclude-paths="sf/substreams,google"
-```
-
-The command above should put the generate rust files under `/src/pb`. You
-can start using these now in your module handlers: See
-the [official substreams documentation](https://thegraph.com/docs/en/substreams/getting-started/quickstart/#create-substreams-module-handlers)
-on
-how to implement module handlers.
-
-You can also look into already existing substreams packages to see how it
-is done. E.g. [ethereum-ambient](./ethereum-ambient/) provides a pretty good
-example of how to get access to raw contract storage.
-
-# Tests
-
-To create a block test asset for ethereum do the following:
-
-- Follow [this tutorial](https://substreams.streamingfast.io/tutorials/overview/map_block_meta_module). Make sure you
-  set up the substreams-explorer repo in the same directory as this repo.
-    - Comment out `image: ./ethereum.png` in `ethereum-explorer/substreams.yaml`
-    - Add `prost-types = "0.11.0"` to `ethereum-explorer/Cargo.toml`
-- Make sure you set up your key env vars.
-- Run `sh scripts/download-ethereum-block-to-s3 BLOCK_NUMBER`
-
-Do not commit the block files (they are quite big).
