+## Set up diagnostics
+
+First you need to build the diagnostics image:
+
+```
+git clone https://github.com/erigontech/diagnostics.git
+cd diagnostics
+
+# Note: https://github.com/erigontech/diagnostics/pull/99 is needed to fix the build
+make build-docker
+```
+
+Then start the diagnostics container:
+
+```
+docker compose up -d erigon-diagnostics
+```
+
+Now you can see the diagnostics page at `http://<your-server-ip>:8080`
+
+Follow the instructions [here](https://erigon.gitbook.io/erigon/diagnostic-tool/setup#id-3.-create-a-new-session-in-the-diagnostic-tool) to create a new session and copy the session pin
+
+Then set `DIAGNOSTICS_SESSION` in `.env`
+
+Now start the erigon-support container to connect the diagnostics session to the erigon node:
+
+```
+docker compose up -d erigon-support
+```
+
+Once the diagnostics tool is successfully connected to the Erigon node, return to your web browser and reload the page.
