+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"
 ```
-
 After that, you can resume the normal Observing Squad installation steps.
 
+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.

+[[Observers]]
+    ShardId = 0
+    Address = "http://127.0.0.1:8080"

-### Handle missing dependencies of sc-meta
-
-`sc-meta` requires a few dependencies that are not installed by default on some systems. In this case, installation of `sc-meta` fails.
