Could mention here some tech that uses raft. From what I can figure out: NATS, Elasticsearch, and Etcd are some I think

This sentence has poor grammar, can you improve this? "concensus algirhtm means" "same imformation, data..."

consensus can not do things. consensus is a state of agreement.

Leader is not a proper noun. 'leader' is better, and you can bold it for emphasis.

'consensus algorithms'
'guarantee is'
'cluster availability'
'when the server leader'

'crashes'.
Is it actually immediately?

| Consensus algorithm is usually used in distributed systems to solve some consensus issues. |

I think this sentence can be removed and you can mention 'distributed systems' in the first sentences.

'is a number marked for the period at the beginning of Leader voting until the vote is successful,'
Is difficult to undestand.

I introduce about Consensus algorithm, Raft's properties and some way Raft do to achieve consistency.
