-GoDoxy v0.9.1 expected changes
+## GoDoxy v0.10.0
 
-- Support Ntfy notifications
-- Prometheus metrics server now inside API server under `/v1/metrics`
-  - `GODOXY_PROMETHEUS_ADDR` removed
-  - `GODOXY_PROMETHEUS_ENABLED` added, default `false`
+### GoDoxy Agent
+
+Maintain secure connection between main server and agent server by authenticating and encrypting connection with mTLS.
+
+Main benefits:
+
+- No more exposing docker socket: drops the need of `docker-socket-proxy`
+- No more exposing app ports: fewer attack surface
+  ```yaml
+  services:
+    app:
+      ...
+      # ports: # this part is not needed on agent server
+      #  - 6789
+  ```
+- Secure: no one can connect to it except GoDoxy main server because of mTLS, plus connection is encrypted
+- Fetch info from agent server, e.g. CPU usage, Memory usage, container list, container logs, etc... (to be ready for beszel and dockge like features in WebUI)
+
+#### How to setup
+
+Prerequisites:
+
+- GoDoxy main server must be running
+
+1. Create a directory for agent server, cd into it
+2. Copy `agent.compose.yml` into the directory
+3. Modify `agent.compose.yml` to set `REGISTRATION_ALLOWED_HOSTS`
+4. Run `docker-compose up -d` to start agent
+5. Follow instructions on screen to run command on GoDoxy main server
+6. Add config output to GoDoxy main server in `config.yml` under `providers.agents`
+   ```yaml
+   providers:
+     agents:
+       - 12.34.5.6:8889
+   ```
+
+### How does it work
+
+Setup flow:
+
+```mermaid
+flowchart TD
+    subgraph Agent Server
+        A[Create a directory] -->
+        B[Setup agent.compose.yml] -->
+        C[Set REGISTRATION_ALLOWED_HOSTS] -->
+        D[Run agent] -->
+        E[Wait for main server to register]
+
+        F[Respond to main server]
+        G[Agent now run in agent mode]
+    end
+    subgraph Main Server
+      E -->
+      H[Run register command] -->
+      I[Send registration request] --> F -->
+      J[Store client certs] -->
+      K[Send done request] --> G -->
+      L[Add agent to config.yml]
+    end
+```
+
+Run flow:
+
+```mermaid
+flowchart TD
+    subgraph Agent HTTPS Server
+        aa[Load CA and SSL certs] -->
+        ab[Start HTTPS server] -->
+
+        ac[Receive request] -->
+        ad[Verify client cert] -->
+        ae[Handle request] --> ac
+    end
+    subgraph Main Server
+        ma[Load client certs] -->
+        mb[Query agent version] --> ac
+        mb --> mc[Check if agent version matches] -->
+        md[Query agent info] --> ac
+        md --> ae --> me[Store agent info]
+    end
+```
