+## Automating fee adjustment
+
+I finally found a way to use `charge-lnd` with Umbrel. I followed the
+instructions
+[here](https://community.getumbrel.com/t/guide-installing-charge-lnd-in-a-docker-to-automate-your-fee-policies/2187)
+. My own custom stuff changes were:
+
+- I put my config file in: `/media/data_disk/charge.conf`
+- I wrote my docker run statement as follows:
+
+```commandline
+docker run --rm -it --network=umbrel_main_network 
+-e GRPC_LOCATION=10.21.21.9:10009 
+-e LND_DIR=/data/.lnd 
+-e CONFIG_LOCATION=/app/charge.config 
+-v /media/data_disk/umbrel/lnd:/data/.lnd 
+-v /media/data_disk/charge.config:/app/charge.config accumulator/charge-lnd:latest
+```
+
+I've been reading a bit and apparently it's not a good idea to run price
+adjustments very frequently given that it makes it difficult for other nodes to
+plan their routes, so automated software will see it as a low quality attribute
+for routing nodes. I have decided to leave a weekly cronjob for now, so the
+fees will update automatically every thursday at 10pm.
