Drop parts when it was downloading files from this GitHub repository, when you need to upload init script and so on, because the provided package in OpenWrt 19.07+ does that. Btw, 19.07 is the currently supported release and 18.06 is already EoL. So, it is enough to use opkg.

## Which method to use?
The basic `opkg` package installation is for those looking for a simple no-frills installation, where updates are at the discretion of the [package maintainer](https://github.com/openwrt/packages/tree/openwrt-19.07/net/dnscrypt-proxy2). Success is dependent upon the updated state of the package, it may not work if it goes stale. **This is only available for OpenWrt 19.07+**

The advanced manual installation offers more flexibility, and is the preferred method for the more competent users.

## Manual installation (Advanced)
### Download
### Download and install
Download the [latest binary here](https://github.com/DNSCrypt/dnscrypt-proxy/releases/latest). Get the right binary for your architecture. If you get a strange `parse error` later when trying to run the executable file, chances are that you didn't pick the right file for the CPU of your router. Here are some common examples:
```
Netgear R7800 - linux_arm
Ubiquiti EdgeRouter X - linux_mipsle
```
### Optional: compress the executable
The `dnscrypt-proxy` file is quite large, but can be compressed for a massive reduction of its size, from ~12 MB down to ~2 MB.
In order to do so, use [UPX](https://upx.github.io/) on any platform (Windows, Linux, macOS...) with the following command:
```sh
upx --lzma dnscrypt-proxy
```
### Tweak the example file
Rename `example-dnscrypt-proxy.toml` to `dnscrypt-proxy.toml`, and change at least the following line:
```toml
listen_addresses = ['127.0.0.1:53', '[::1]:53']
```
to (notice the IP address change):
```toml
listen_addresses = ['127.0.0.53:53']
```
### Install the files on the router
Use `scp` to copy:
* `dnscrypt-proxy` to `/usr/sbin/`
* The modified `dnscrypt-proxy.toml` file to `/etc/config/`
* [This `init.d` file](https://raw.githubusercontent.com/etam/DNS-over-HTTPS-for-OpenWRT/master/dnscrypt-proxy) by @etam saved as `/etc/init.d/dnscrypt-proxy`
Then use `ssh` to log on the router and type:
```sh
chmod +x /usr/sbin/dnscrypt-proxy
chmod +x /etc/init.d/dnscrypt-proxy
```
### Install the ca-bundle package on the router
The ca-bundle package is not installed by default in OpenWrt, which will cause issues if not installed.
Use SSH to connect to your router and proceed with these two commands:
```sh
opkg update
opkg install ca-bundle
opkg install dnscrypt-proxy2
```
### Check that the proxy is properly installed
