+
+### Does my node work properly?
+Your node should have at least 40 connected peers and you should see some traffic in and out, in the Grafana board.
+
+1. Run `docker ps` and check that the “[harbor.status.im/wakuorg/nwaku](http://harbor.status.im/wakuorg/nwaku)” container is not continuously restarting
+2. Use the following commands to check the node better:
+    1. `curl -X GET http://localhost:8645/health`
+    2. `curl -X GET http://localhost:8645/debug/v1/info`
+    3. `curl -X GET http://localhost:8645/debug/v1/version`
+    4. `curl -X GET http://localhost:8645/admin/v1/peers`
+    5. `curl -X GET http://localhost:8645/admin/v1/filter/subscriptions`
+    6. `curl -X GET http://localhost:8003/metrics`
+3. Check the following local services:
+    1. Grafana: [http://localhost:3000/](http://localhost:4000/)
+    2. Local node front end: http://localhost:4000/
+
+
+### My node is not able to start properly
+If you are using Contabo, we recommend moving to a different VPS vendor.
+If not, remove the keystore and rln_tree folders, run the ./register_rln script again, and try to run your node again.
+
+### Does running a node have any incentives?
+There are currently no incentives in place, but it's something currently being researched and designed.
+
+### Error when running .register_rln.sh
+

+
+There is a problem with you EthClient account.
+Take a closer look on how you set the values of the .env file paying attention to example, and make sure you have a valid EthClient.
+
+### Does my Grafana looks right?
+
+It should look like:
