-## :book: About
+## 📖 About
 
-## 🤖 Quickstart
+Swarmproxy is a simply way to integrate a http proxy in your Docker swarm cluster or any other container network.
+It acts as an centralized proxy to limit your outbound / egress traffic. You can also add a whitelist filter to
+limit the allowed domains. There is also an option to use a upstream proxy.
+
+### What does Swarmproxy for you?
+
+Enterprise and production environments often face more stringent security requirements.
+Therefore, unfiltered Internet access may be prohibited.
+
+So Swarmproxy could help you with these features:
+
+- ✔️ Prevent direct web access from Container workload.
+- ✔️ Upstream proxy with or without authentication
+- ✔️ Optional domain based whitelist filter.
+
+### What does Swarmproxy not?
+
+Swarmproxy is just a supercharged Tinyproxy where you can point your container workload to.
+
+- ☣️ Swarmproxy does not block the web access or other traffic if you workload doesn't use a proxy
+- ☣️ It's not a firewall, thus it does not customize your iptables or any other firewall policies.

+## Upstream proxy example `(2-upstream.yml)`
+
+### Source

+configured Swarmproxy instance which forwards the query to the upstream.
+
+### Usage
+
+```bash
+docker stack deploy -c 2-upstream.yml swarmproxy-upstream

+## Fullstack example with external secrets and config `(3-external.yml)`
+
+### Source
+
+> 🗄️ File: [3-upstream.yml](3-upstream.yml)
+
+### Description
+
+This stack is based on the previous upstream example. It's modified to show these additional features:
+
+- Using external docker secret to set up an upstream proxy. Should be used when upstream needs authentication
+- Mounting a docker config as filter file
+- filtering queries by domains
+- added curl-blocked service to show output if target domain is not in whitelist
+
+### Usage
+
+```bash
+echo "google.com" | docker config create filter_file -
+echo "upstream:8888" | docker secret create upstream-proxy -
+docker stack deploy -c 1-minimal.yml swarmproxy-mini
