+## ignite testnet
+
+Start a testnet local
+
+**Synopsis**
+
+The commands in this namespace allow you to start your local testnet for development purposes. Currently there is only one feature to create a testnet from any state network (including mainnet).
+
+
+The "in-place" command is used to create and start a testnet from current local net state(including mainnet).
+After using this command in the repo containing the config.yml file, the network will start.
+We can create a testnet from the local network state and mint additional coins for the desired accounts from the config.yml file.
+
+During development, in-place allows you to quickly reboot the chain from a multi-node network state to a node you have full control over.

+## ignite testnet in-place 
+
+Create and start a testnet from current local net state
+
+**Synopsis**
+
+The "in-place" command is used to create and start a testnet from current local net state(including mainnet). 
+
+We can create a testnet from the local network state and mint additional coins for the desired accounts from the config.yml file.
+
+During development, in-place allows you to quickly reboot the chain from a multi-node network state to a node you have full control over.
+
+By default, the data directory will be initialized in $HOME/.mychain, where "mychain" is the name of the project. To set a custom data directory use the --home flag or set the value in config.yml:
+
+	validators:
+	  - name: alice
+	    bonded: '100000000stake'
+	    home: "~/.customdir"
+
+Get mint coin just add account in config.yml file:
+
+      accounts: 
+      - name: charlie
+      coins:
+      - 20000token
+      - 200000000stake
