+<!--
+Guiding Principles:
+
+Changelogs are for humans, not machines.
+There should be an entry for every single version.
+The same types of changes should be grouped.
+Versions and sections should be linkable.
+The latest version comes first.
+The release date of each version is displayed.
+Mention whether you follow Semantic Versioning.
+
+Usage:
+
+Changelog entries are generated by git cliff ref: https://github.com/orhun/git-cliff
+
+Each commit should be conventional, the following message groups are supported.
+
+* feat: A new feature
+* fix: A bug fix
+* docs: Documentation only changes
+* style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
+* refactor: A code change that neither fixes a bug nor adds a feature
+* perf: A code change that improves performance
+* test: Adding missing tests or correcting existing tests
+* build: Changes that affect the build system or external dependencies (example scopes: go, npm)
+* ci: Changes to our CI configuration files and scripts (example scopes: GH Actions)
+* chore: Other changes that don't modify src or test files
+* revert: Reverts a previous commit
+
+When a change is made that affects the API or state machine, the commit message prefix should be suffixed with `!`.

+# System Tests
+
+This package contains the testing framework for black-box system tests. It includes a test runner that sets up a 
+multi-node blockchain locally for use in tests. The framework provides utilities and helpers for easy access and 
+setup in tests.
+
+## Components
+
+- **CLI**: Command-line interface wrapper for interacting with the chain or keyring
+- **Servers**: Server instances to run the blockchain environment.
+- **Events**: Event listeners
+- **RPC**: Remote Procedure Call setup for communication.
+
+## Dependencies
+
+- **testify**: Testing toolkit.
+- **gjson**: JSON parser.
+- **sjson**: JSON modifier.
+
+Server and client-side operations are executed on the host machine.
+
+## Developer
+
+### Test strategy
+
+System tests cover the full stack via cli and a running (multi node) network. They are more expensive (in terms of time/ cpu) 
+to run compared to unit or integration tests. 
+Therefore, we focus on the **critical path** and do not cover every condition.
+
+## How to use
+
+Read the [getting_started.md](../tests/systemtests/getting_started.md) guide to get started.
+
+### Execute a single test
+
+```sh
+go test -tags system_test -count=1 -v . --run TestStakeUnstake  -verbose
+```
+
+Test cli parameters
+
+* `-verbose` verbose output
+* `-wait-time` duration - time to wait for chain events (default 30s)
+* `-nodes-count` int - number of nodes in the cluster (default 4)
+
+# Port ranges
+
+With *n* nodes:
+
+* `26657` - `26657+n` - RPC
+* `1317` - `1317+n` - API
+* `9090` - `9090+n` - GRPC
+* `16656` - `16656+n` - P2P
+
+For example Node *3* listens on `26660` for RPC calls
+
+## Resources
+
+* [gjson query syntax](https://github.com/tidwall/gjson#path-syntax)
+
+## Disclaimer
+
+This is based on the system test framework in [wasmd](https://github.com/CosmWasm/wasmd) built by Confio.
