## Basic Examples
To create or update the key named "redis/config/connections" to the value "5" in
2017-04-04 16:33:22 +00:00
Consul's KV store:
2016-09-26 15:12:53 +00:00
2020-05-19 18:32:38 +00:00
```shell-session
2016-09-26 15:12:53 +00:00
$ consul kv put redis/config/connections 5
Success! Data written to: redis/config/connections
```
To read a value back from Consul:
2020-05-19 18:32:38 +00:00
```shell-session
2016-09-26 15:12:53 +00:00
$ consul kv get redis/config/connections
5
```
Or you can query for detailed information:
2020-05-19 18:32:38 +00:00
```shell-session
2016-09-26 15:12:53 +00:00
$ consul kv get -detailed redis/config/connections
CreateIndex 336
Flags 0
Key redis/config/connections
LockIndex 0
ModifyIndex 336
Session -
Value 5
```
Finally, deleting a key is just as easy:
2020-05-19 18:32:38 +00:00
```shell-session
2016-09-26 15:12:53 +00:00
$ consul kv delete redis/config/connections
Success! Data deleted at key: redis/config/connections
