+share to the infrastructure of the blockchain world.
+CSC is a small part of the development prospect. The CSC CLI is a basic tool to launch
+relay node, validator and manage wallets.
 
-The general synopsis is as follows:
+This is a docker version of csc CLI.
+
+Contribution is welcome.
+
+## Usage
+
+To show CSC CLI help:
 
 .. code-blok:: bash
 
-  docker run --interactive \
+  docker run --interactive --rm \
      ghcr.io/coincodile/cetd \
-         (Era based commands | Byron specific commands | Miscellaneous commands)
+         --help
+
+## Initialize
+
+to initialization, in terminal type:
+
+.. code-blok:: bash
+
+  docker run --interactive --rm \
+    --volume .:/data \
+    ghcr.io/coincodile/cetd \
+      --datadir /data \
+      init
+
+This command will create the data directory and keystore directory under /path/your-data-localtion-fold, 
+and create Genesis Block.If the default --datadir is not specified, it will create .cetd as the data 
+directory and 'keystore' directory in the current user's home directory. As follows:
+
+
+.. code-blok:: bash
+
+       .
+       ├── cetd
+       │   ├── chaindata
+       │   │   ├── 000001.log
+       │   │   ├── CURRENT
+       │   │   ├── LOCK
+       │   │   ├── LOG
+       │   │   └── MANIFEST-000000
+       │   ├── lightchaindata
+       │   │   ├── 000001.log
+       │   │   ├── CURRENT
+       │   │   ├── LOCK
+       │   │   ├── LOG
+       │   │   └── MANIFEST-000000
+       │   ├── LOCK
+       │   └── nodekey
+       └── keystore
+
+By default, init command is initialized to Mainnet information, and --testnet option is initialized to testnet information.
+
+## Run
+
+Startup command:
+
+.. code-blok:: bash
+
+  docker run --interactive --rm \
+    --volume .:/data \
+    ghcr.io/coincodile/cetd \
+      --datadir /data
+
+By default, the synchronization mode is fast, which can be changed to full mode with the option --syncmode full. We have
+assigned P2P seed Node in cetd by default. You can change and assign trusted Seed Nodes via --bootnodes options.
