-Dozzle is a log viewer for Docker. It's free. It's small. And it's right in your browser. Oh, did I mention it is also real-time?
+Dozzle is a simple, lightweight application that provides you with a web based interface to monitor your Docker container logs live. It doesn’t store log information, it is for live monitoring of your container logs only.
 
-While dozzle should work for most, it is not meant to be a full logging solution. For enterprise use, I recommend you look at [Loggly](https://www.loggly.com), [Papertrail](https://papertrailapp.com) or [Kibana](https://www.elastic.co/products/kibana).

-But if you don't want to pay for those services, then you are in luck! Dozzle will be able to capture all logs from your containers and send them in real-time to your browser. Installation is also very easy.
+Dozzle doesn't cost any money. Dozzle aims to stay simple, small and free.

+## Troubleshooting and FAQs
+
+<details>
+ <summary>I installed Dozzle, but logs are slow or they never load. Help!</summary>
+
+ Dozzle uses Server Sent Events (SSE) which connects to a sever using a HTTP stream without closing the connection. If any proxy tries to buffer this connection, then Dozzle never receives the data and hangs forever waiting for the reverse proxy to flush the buffer.  Since version `1.23.0`, Dozzle send the `X-Accel-Buffering: no` header which should stop reverse proxies buffering. However, some proxies may ignore this header. In those case, you need to explicitly disable any buffering.
+
+ Below is an example with nginx and using `proxy_pass` to disable buffering.
+
+```
+    server {
+        ...
+
+        location / {
+            proxy_pass                  http://<dozzle.container.ip.address>:8080;
+        }
+
+        location /api {
+            proxy_pass                  http://<dozzle.container.ip.address>:8080;
+
+            proxy_buffering             off;
+            proxy_cache                 off;
+        }
+    }
+
+```
+</details>
+
+<details>
+ <summary>What data does Dozzle collect?</summary>
+
+ Dozzle does not collect any metrics or analytics. Dozzle has a [strict](https://github.com/amir20/dozzle/blob/master/routes.go#L33-L38) Content Security Policy which only allows the following policies:
+
+ - Allow connect to `api.github.com` to fetch most recent version.
+ - Allow fonts from `fonts.gstatic.com` and styles from `fonts.googleapis.com`
+ - Only allow `<script>` and `<style>` files from `self`
+
+ Dozzle opens all links with `rel="noopener"`.
