Multiple additions and fixes #12

- Unbound ran as `nonrootuser`
- Readme updated
- auth.conf replaced by `USER` and `PASSWORD` env variables
- Removed Nginx section from readme for now
- Reworked entrypoint with more checks
- Malicious IPs and hostnames building is done at Docker build to gain time at launch
- docker-compose updated to reflect changes

 ## Connect other containers to it
 
 Connect other Docker containers to the PIA VPN connection by adding `--network=container:pia` when launching them.

+## For the paranoids
 
-## EXTRA: Access ports of containers connected to the VPN container
+- You can review the code which essential consits in the [Dockerfile](https://github.com/qdm12/private-internet-access-docker/blob/master/Dockerfile) and [entrypoint.sh](https://github.com/qdm12/private-internet-access-docker/blob/master/entrypoint.sh)
-
+- Build the images yourself:
-You have to use another container acting as a Reverse Proxy such as Nginx.
-
-**Example**:
-
-- We launch a *Deluge* (torrent client) container with name **deluge** connected to the `pia` container with:
 
     ```bash
-    docker run -d --name=deluge --network=container:pia linuxserver/deluge
+    docker build -t qmcgaw/private-internet-access https://github.com/qdm12/private-internet-access-docker.git
     ```
 
-- We launch a *Hydra* container with name **hydra** connected to the `pia` container with:
+- The download and unziping of PIA openvpn files is done at build for the ones not able to download the zip files
-
+- Checksums for PIA openvpn zip files are not used as these files change often (but HTTPS is used)
-    ```bash
+- Use `-e ENCRYPTION=strong -e BLOCK_MALICIOUS=on`
-    docker run -d --name=hydra --network=container:pia linuxserver/hydra
-    ```
-
-- HTTP User interfaces are accessible at port 8112 for Deluge and 5075 for Hydra
-
-1. Create the Nginx configuration file *nginx.conf*:
-
-    ```txt
-    user  nginx;
-    worker_processes  1;
-    error_log  /var/log/nginx/error.log warn;
-    pid        /var/run/nginx.pid;
-    events {

-            }
-        }
-        include /etc/nginx/conf.d/*.conf;
-    }
-    ```
-
-1. Run the Alpine [Nginx container](https://hub.docker.com/_/nginx) with:
-
-    ```bash
-    docker run -d --name=proxypia -p 8001:1001 -p 8002:1002 \
-    --network=pianet --link pia:deluge --link pia:hydra \
-    -v /mypathto/nginx.conf:/etc/nginx/nginx.conf:ro nginx:alpine
-    ```
-
-1. Access the WebUI of Deluge at [localhost:8000](http://localhost:8000)
-
-For more containers, add more `--link pia:xxx` and modify *nginx.conf* accordingly
-
-## EXTRA: For the paranoids
-
-- You might want to build the Docker image yourself
-- The download and unziping is done at build for the ones not able to download the zip files through their ISP
-- Checksums for PIA openvpn zip files are not used as these files change often
-- You should use strong encryption for the environment variable `ENCRYPTION`
-- Let me know if you have any extra idea :) !
 
 ## TODOs
 
-- [ ] Test pia with port mappings and without pia_net and nginx
+- [ ] Malicious IPs and hostnames with wget at launch+checksums
-- [ ] Iptables should change after initial ip address is obtained
+- [ ] Su Exec (fork and addition)
-- [ ] More checks for environment variables provided
+- [ ] SOCKS proxy/Hiproxy/VPN server for other devices to use the container
-- [ ] Add checks when launching PIA $?
-- [ ] VPN server for other devices to go through the tunnel OR hiproxy
