 ### Foundry Integration
 
-Foundry is utilized for deploying smart contracts. For commands related to deployment, you can pass flags for Foundry
-integration.
+Foundry is used for deploying smart contracts. Pass flags for Foundry integration with the `-a` option, e.g.,
+`-a --gas-estimate-multiplier=500`.
 
 ### Ecosystem
 
-ZK Stack allows you to either create a new ecosystem or connect to an existing one. An ecosystem includes the components
-that connects all ZK chains, like the BridgeHub, the shared bridges, and state transition managers.
+ZK Stack allows you to create a new ecosystem or connect to an existing one. An ecosystem includes components like the
+BridgeHub, shared bridges, and state transition managers.
 [Learn more](https://docs.zksync.io/zk-stack/components/shared-bridges.html).
 
-To create a ZK Stack project, you must first create an ecosystem:
+#### Global Config
+
+- `--verbose`: Show all output from all commands.
+- `--chain`: Use a specific chain for ecosystem operations.
+- `--ignore-prerequisites`: Do not verify prerequisites. !!!WARNING!!! This option won't show errors if required tools
+  for network deployment and operation are missing.
+
+#### Create
+
+To create a ZK Stack project, start by creating an ecosystem:
 
 ```bash
 zk_inception ecosystem create
 ```
 
-If you chose to not start database & L1 containers after creating the ecosystem, you can later run
-`zk_inception containers`
+If you choose not to start database & L1 containers after creating the ecosystem, you can later run:
+
+```bash
+zk_inception containers
+```
 
-All subsequent commands should be executed from within the ecosystem folder you created:
+Execute subsequent commands from within the created ecosystem folder:
 
 ```bash
-cd `path/to/ecosystem/name`
+cd path/to/ecosystem/name
 ```
 
-If the ecosystem has never been deployed before, initialization is required:
+#### Init
+
+If the ecosystem has never been deployed before, initialize it:
 
 ```bash
 zk_inception ecosystem init
 ```
 
-This command also initializes the first ZK chain. Note that the very first chain becomes the default one, but you can
-override it with another by using the `--chain <name>` flag.
+This initializes the first ZK chain, which becomes the default. Override with `--chain <name>` if needed. For default
+params, use:
+
+```bash
+zk_inception ecosystem init --dev
+```
+
+If the process gets stuck, resume it with `--resume`. This flag keeps track of already sent transactions and sends new
+ones with provided params.
+
+#### Verifying Contracts
+
+To verify contracts, use the `--verify` flag.
+
+- `--verifier name`: Verification provider. Options: etherscan, sourcify, blockscout (default: etherscan). Note: Add "
+  /api?" to the end of the Blockscout homepage explorer URL.
+- `--verifier-url` url: Optional verifier URL for submitting the verification request.
+- `--verifier-api-key`: Verifier API key.
 
-To change the default ZK chain, use:
+#### Changing Default Chain
+
+To change the default ZK chain:
 
 ```bash
 zk_inception ecosystem change-default-chain
 ```
 
-IMPORTANT: It is not yet possible to use an existing ecosystem and register a chain to it. this feature will be added in
-the future.
+IMPORTANT: Currently, you cannot use an existing ecosystem to register a new chain. This feature will be added in the
+future.
 
 ### ZK Chain
 
-Upon ecosystem creation, the first ZK chain is automatically generated. However, you can create additional chains and
-switch between them:
+#### Create
+
+The first ZK chain is generated upon ecosystem creation. Create additional chains and switch between them:
 
 ```bash
 zk_inception chain create
 ```
 
-Once created, contracts for the ZK chain must be deployed:
+#### Init
+
+Deploy contracts and initialize Zk Chain:
 
 ```bash
 zk_inception chain init
 ```
 
-Initialization utilizes the ecosystem's governance to register it in the BridgeHub.
+This registers the chain in the BridgeHub and deploys all necessary contracts. Manual initialization steps:
 
-If contracts were deployed by a third party (e.g., MatterLabs), you may need to run the genesis process locally:
+`init`: Register in BridgeHub, deploy L2 contracts, and create genesis (preferred method). `deploy-l2-contracts`: Deploy
+L2 bridge and Default Upgrade Contracts. `initialize-bridges`: Deploy L2 bridge. `upgrader`: Deploy Default Upgrade
+Contract. `deploy-paymaster`: Deploy paymaster. `genesis`: Run genesis after deploying contracts (preferred if deployed
+by a third party).
 
-```bash
-zk_inception chain genesis
-```
+### ZK Server
 
-This ensures proper initialization of the server.
-
-### Zk Server
-
-For running the chain:
+To run the chain:
 
 ```bash
 zk_inception server
 ```
 
-You can specify the chain you are running by providing `--chain <chain_name>` argument
+You can specify the component you want to run using `--components` flag
+
+Specify the chain with `--chain <chain_name>`.

-To run the prover, follow these steps:
-
-First, initialize the prover:
+Initialize the prover:
 
 ```bash

+zk_inception prover init
 ```
 
-You can generate the setup keys with:
+Generate setup keys:
 
 ```bash
 zk_inception prover generate-sk
 ```
 
-Finally, run the prover:
+Run the prover:
 
 ```bash

-`gateway, witness-generator, witness-vector-generator, prover, compressor`
-
-If you are running `witness-generator` you can specify the round by providing `--round <round>` argument. Possible
-rounds are: `all-rounds, basic-circuits, leaf-aggregation, node-aggregation, recursion-tip, scheduler`
+Specify the prover component with `--component <component>`. Components:
+`gateway, witness-generator, witness-vector-generator, prover, compressor`.
 
 For `witness-vector-generator`, specify the number of WVG jobs with `--threads <threads>`.
 
-### Contract verifier
+For `witness-generator`, specify the round with `--round <round>`. Rounds:
