 The idea is to provide an `atomkraft` cli, which initializes a [poetry](https://python-poetry.org) project with [pytest](https://docs.pytest.org) dependency and other necessary configurations.
 
-## Decision
+## Summary
 
-To set up an `atomkraft` project,
+- Set up a poetry project at the current directory.
+- Perform lightweight smoke tests right out of the box.
+- Configure chain parameters via CLI.
 
-- `atomkraft init BINARY DIR` is executed which sets up a poetry project at `DIR`.
-- After changing the directory to `DIR`, a user should be able to execute some kick-the-tire tests (included in Atomkraft) for standard Cosmos-SDK modules right out of the box.
-- The chain parameters can be queried/modified using `atomkraft chain config CONFIGFILE KEYPATH [VALUE]`
-- A testnet can be started via `atomkraft chain up [-d]`.
-- A testnet can be shut down via `atomkraft chain down`.
+### `atomkraft init BINARY [TEST]...`
 
-## Summary
+This command is used to initialize an Atomkraft project in the current directory.
+It uses [copier](https://pypi.org/project/copier) to copy a template and dynamically update project variables.
+
+#### Arguments
+
+- `BINARY` is path to Cosmos-SDK chain binary.
+  - "gaiad"
+  - "/opt/cosmos-chains/junod"
+- `[TEST]...` is a list of provided lightweight tests that can be included in the project.
+  - "authz"
+  - "cosmwasm"
+  - "feegrant"
+
+#### Template directory structure
+
+```
+.
+├── atomkraft.toml
+├── chain.toml
+├── modelator.toml
+├── models
+├── reactors
+│   ├─── authz.py
+│   └─── cosmwasm.py
+├── reports
+├── tests
+│   ├─── conftest.py
+│   ├─── test_authz.py
+│   └─── test_cosmwasm.py
+└── traces
+```
+
+#### `atomkraft.toml`
+
+This file is used for any top-level project configuration.
+
+- The lightweight tests are marked in `atomkraft.toml` file.
+
+A typical `atomkraft.toml` may look like this.
+
+```
+[chain]
+binary = "gaia"
+
+[modelator.apalache]
+jar = "/path/to/apalache/jar"
+
+[tests]
+lightweight = ["authz", "cosmwasm"]
+```
+
+### `atomkraft chain config FILE KEY [VALUE]`
+
+This command can be used to query or update chain parameters.
+
+#### Arguments
+
+- `KEY` is a nested key.
+  - `coin`
+  - `"app.api.enable"`
+  - `"config.p2p.allow_duplicate_ip"`
+  - `"genesis.app_state.gov.voting_params.voting_period"`
+
+Note, `app`, `config` and `genesis` prefixes. They correspond to the usual `app.toml`, `config.toml`, and `genesis.json` files in a Cosmos-SDK chain node data directory.
+
+- `VALUE` is used to overwrite the current value. If it is skipped, the current value is printed.
+
+The config values are stored in `chain.toml` file.
+
+### `atomkraft chain test-drive`
+
+After running `atomkraft init` (with included tests) and `atomkraft chain config`, the project should be ready to perform some lightweight tests.
+
+`atomkraft chain test-drive` will run the light-weight tests using `reactors/*py` and `tests/test_*py`.
+
+## Future work
 
-- `atomkraft init` to initialize atomkraft project as a poetry project with python 3.10 and pytest dependency
-- `atomkraft test-drive` to execute a set of standard Cosmos-SDK tests using provided chain binary.
-- `atomkraft chain config CONFIGFILE KEYPATH [VALUE]` to update chain configuration.
-- `atomkraft chain [up|down]` to control a testnet.
+- Spawn independent testnet via `atomkraft chain [up|down]`.
+- Spawn blockchain explorer via `atomkraft chain explorer [up|down] [PORT]`.
+- Spawn testnet with an explorer via `atomkraft chain --explorer [up|down]`.
