+# Development container
+
+Development container that can be used with VSCode.
+
+It works on Linux, Windows (WSL2) and OSX.
+
+## Requirements
+
+- [VS code](https://code.visualstudio.com/download) installed
+- [VS code dev containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) installed
+- [Docker](https://www.docker.com/products/docker-desktop) installed and running
+
+## Setup
+
+1. Create the following files and directory on your host if you don't have them:
+
+    ```sh
+    touch ~/.gitconfig ~/.zsh_history
+    mkdir -p ~/.ssh
+    ```
+
+1. **For OSX hosts**: ensure the project directory and your home directory `~` are accessible by Docker.
+1. Open the command palette in Visual Studio Code (CTRL+SHIFT+P).
+1. Select `Dev-Containers: Open Folder in Container...` and choose the project directory.
+
+## Customization
+
+For any customization to take effect, you should "rebuild and reopen":
+
+1. Open the command palette in Visual Studio Code (CTRL+SHIFT+P)
+2. Select `Dev-Containers: Rebuild Container`
+
+Changes you can make are notably:
+
+- Changes to the Docker image in [Dockerfile](Dockerfile)
+- Changes to VSCode **settings** and **extensions** in [devcontainer.json](devcontainer.json).
+- Change the entrypoint script by adding a bind mount in [devcontainer.json](devcontainer.json) of a shell script to `/root/.welcome.sh` to replace the [current welcome script](https://github.com/qdm12/godevcontainer/blob/master/shell/.welcome.sh). For example:
+
+    ```json
+    // Welcome script
+    {
+        "source": "/yourpath/.welcome.sh",
+        "target": "/root/.welcome.sh",
+        "type": "bind"
+    },
+    ```
+
+- More options are documented in the [devcontainer.json reference](https://containers.dev/implementors/json_reference/).

+name: Support a VPN provider
+about: Suggest a VPN provider to be supported
+title: 'VPN provider support: NAME OF THE PROVIDER'
+labels: ":bulb: New provider"
+
+---
+
+Important notes:
+
+- There is no need to support both OpenVPN and Wireguard for a provider, but it's better to support both if possible
+- We do **not** implement authentication to access servers information behind a login. This is way too time consuming unfortunately
+- If it's not possible to support a provider natively, you can still use the [the custom provider](https://github.com/qdm12/gluetun-wiki/blob/main/setup/providers/custom.md)
+
+## For Wireguard
+
+Wireguard can be natively supported ONLY if:
+
+- the `PrivateKey` field value is the same across all servers for one user account
+- the `Address` field value is:
+  - can be found in a structured (JSON etc.) list of servers publicly available; OR
+  - the same across all servers for one user account
+- the `PublicKey` field value is:
+  - can be found in a structured (JSON etc.) list of servers publicly available; OR
+  - the same across all servers for one user account
+- the `Endpoint` field value:
+  - can be found in a structured (JSON etc.) list of servers publicly available
+  - can be determined using a pattern, for example using country codes in hostnames
+
+If any of these conditions are not met, Wireguard cannot be natively supported or there is no advantage compared to using a custom Wireguard configuration file.
+
+If **all** of these conditions are met, please provide an answer for each of them.
+
+## For OpenVPN
+
+OpenVPN can be natively supported ONLY if one of the following can be provided, by preference in this order:
+
+- Publicly accessible URL to a structured (JSON etc.) list of servers **and attach** an example Openvpn configuration file for both TCP and UDP; OR
+- Publicly accessible URL to a zip file containing the Openvpn configuration files; OR
+- Publicly accessible URL to the list of servers **and attach** an example Openvpn configuration file for both TCP and UDP

- [Alpine 3.12](https://alpinelinux.org) for a tiny image (37MB of packages, 6.7MB of Go binary and 5.6MB for Alpine)

-## Connect to it
-
-There are various ways to achieve this, depending on your use case.
-
- <details><summary>Connect containers in the same docker-compose.yml as Gluetun</summary><p>
-
-    Add `network_mode: "service:gluetun"` to your *docker-compose.yml* (no need for `depends_on`)
-
-    </p></details>
- <details><summary>Connect other containers to Gluetun</summary><p>
-
-    Add `--network=container:gluetun` when launching the container, provided Gluetun is already running
-
-    </p></details>
- <details><summary>Connect containers from another docker-compose.yml</summary><p>
-
-    Add `network_mode: "container:gluetun"` to your *docker-compose.yml*, provided Gluetun is already running
-
-    </p></details>
- <details><summary>Connect LAN devices through the built-in HTTP proxy *Tinyproxy* (i.e. with Chrome, Kodi, etc.)</summary><p>
-
-    You might want to use Shadowsocks instead which tunnels UDP as well as TCP, whereas Tinyproxy only tunnels TCP.
-
-    1. Setup a HTTP proxy client, such as [SwitchyOmega for Chrome](https://chrome.google.com/webstore/detail/proxy-switchyomega/padekgcemlokbadohgkifijomclgjgif?hl=en)
-    1. Ensure the Gluetun container is launched with:
-        - port `8888` published `-p 8888:8888/tcp`
-        - your LAN subnet, i.e. `192.168.1.0/24`, set as `-e EXTRA_SUBNETS=192.168.1.0/24`
-    1. With your HTTP proxy client, connect to the Docker host (i.e. `192.168.1.10`) on port `8888`. You need to enter your credentials if you set them with `TINYPROXY_USER` and `TINYPROXY_PASSWORD`.
-    1. If you set `TINYPROXY_LOG` to `Info`, more information will be logged in the Docker logs
-
-    </p></details>
- <details><summary>Connect LAN devices through the built-in SOCKS5 proxy *Shadowsocks* (per app, system wide, etc.)</summary><p>
-
-    1. Setup a SOCKS5 proxy client, there is a list of [ShadowSocks clients for **all platforms**](https://shadowsocks.org/en/download/clients.html)
-        - **note** some clients do not tunnel UDP so your DNS queries will be done locally and not through Gluetun and its built in DNS over TLS
-        - Clients that support such UDP tunneling are, as far as I know:
-            - iOS: Potatso Lite
-            - OSX: ShadowsocksX
-            - Android: Shadowsocks by Max Lv
-    1. Ensure the Gluetun container is launched with:
-        - port `8388` published `-p 8388:8388/tcp -p 8388:8388/udp`
-        - your LAN subnet, i.e. `192.168.1.0/24`, set as `-e EXTRA_SUBNETS=192.168.1.0/24`
-    1. With your SOCKS5 proxy client
-        - Enter the Docker host (i.e. `192.168.1.10`) as the server IP
-        - Enter port TCP (and UDP, if available) `8388` as the server port
-        - Use the password you have set with `SHADOWSOCKS_PASSWORD`
-        - Choose the encryption method/algorithm to the method you specified in `SHADOWSOCKS_METHOD`
-    1. If you set `SHADOWSOCKS_LOG` to `on`, (a lot) more information will be logged in the Docker logs
-
-    </p></details>
- <details><summary>Access ports of containers connected to Gluetun</summary><p>
-
-    In example, to access port `8000` of container `xyz`  and `9000` of container `abc` connected to Gluetun,
-    publish ports `8000` and `9000` for the Gluetun container and access them as you would with any other container
-
-    </p></details>
- <details><summary>Access ports of containers connected to Gluetun, all in the same docker-compose.yml</summary><p>
-
-    In example, to access port `8000` of container `xyz`  and `9000` of container `abc` connected to Gluetun, publish port `8000` and `9000` for the Gluetun container.
-    The docker-compose.yml file would look like:
-
-    ```yml
-    version: '3.7'
-    services:
-      gluetun:
-        image: qmcgaw/private-internet-access
-        container_name: gluetun
-        cap_add:
-          - NET_ADMIN
-        environment:
-          - USER=js89ds7
-          - PASSWORD=8fd9s239G
-        ports:
-          - 8000:8000/tcp
-          - 9000:9000/tcp
-      abc:
-        image: abc
-        container_name: abc
-        network_mode: "service:gluetun"
-      xyz:
-        image: xyz
-        container_name: xyz
-        network_mode: "service:gluetun"
-    ```
-
-    </p></details>

-## Private Internet Access port forwarding
-
-Note that [not all regions support port forwarding](https://www.privateinternetaccess.com/helpdesk/kb/articles/how-do-i-enable-port-forwarding-on-my-vpn).
-
-When `PORT_FORWARDING=on`, a port will be forwarded on the VPN server side and written to the file specified by `PORT_FORWARDING_STATUS_FILE=/forwarded_port`.
-
-It can be useful to mount this file as a volume to read it from other containers, for example to configure a torrenting client.
-
-## HTTP control server
-
-A built-in HTTP server listens on port `8000` to modify the state of the container. You have the following routes available:
-
- `http://<your-docker-host-ip>:8000/openvpn/actions/restart` restarts the openvpn process
- `http://<your-docker-host-ip>:8000/unbound/actions/restart` re-downloads the DNS files (crypto and block lists) and restarts the unbound process
