+
+## Enter in the container
+
+To obtain bash command line interface inside the container:
+`docker exec -it ethereum-tp /bin/bash`
+
+## Create new ETH account
+

+```
+cd ~/.ethereum/
+geth account new
+```
+
+## Lunch a node with mining
+
+From the container command line (cf `Enter in the container`):
+
+`geth --datadir chaine1T --rpcapi personnal,db,eth,net,web3 --rpc --mine --minerthreads=1 console`
