### Creating a Snapshotless Observing Squad from scratch

If you choose to install a snapshotless observing squad from scratch, you should follow the instruction from the [observing squad section](/integrators/observing-squad) and remember to do the following updates:
* add in the `variables.cfg` file the operation mode in the node's extra flags definition:
If you choose to install a snapshotless Observing Squad from scratch, you should follow the instruction from the [observing squad section](/integrators/observing-squad) and remember to add in the `variables.cfg` file the operation mode in the node's extra flags definition:
```
NODE_EXTRA_FLAGS="-log-save -operation-mode snapshotless-observer"
```
* update the proxy config created by the scripts (found at `$CUSTOM_HOME/elrond-proxy/config/config.toml`). `IsSnapshotless = true` should be added to each observer started with this flag, as follows. Please note that this step is optional.
After that, you can resume the normal Observing Squad installation steps.

Above it's lowercase "observing squad". Can be either, but consistent.


Then, based on the needs there are multiple options concerning the proxy:
* if only a snapshotless squad is needed, nothing else should be done
* if both regular and snapshotless squads are needed:
* with two different proxies: one started with regular observers and one started with snapshotless observers, nothing else should be done
* with only one proxy (being served by all 8 observers), `IsSnapshotless = true` should be added to each observer started with this flag, in the proxy config (found at `$CUSTOM_HOME/elrond-proxy/config/config.toml`), as follows. Please note that this step is optional, although it would help the proxy to forward the requests in an efficient manner.
```toml
[[Observers]]
ShardId = 0
Address = "http://127.0.0.1:8080"
IsSnapshotless = true

[[Observers]]
ShardId = 1
Address = "http://127.0.0.1:8081"
IsSnapshotless = true

[[Observers]]
ShardId = 2
Address = "http://127.0.0.1:8082"
IsSnapshotless = true

[[Observers]]
ShardId = 4294967295
Address = "http://127.0.0.1:8083"
IsSnapshotless = true
```

After that, you can resume the normal Observing Squad installation steps.
