-Armbian Redirector
-==================
-
-This repository contains a redirect service for Armbian downloads, apt, etc.
-
-It uses multiple current technologies and best practices, including:
-
-- Go 1.17/1.18
-- GeoIP + Distance routing
-- Server weighting, pooling (top x servers are served instead of a single one)
-- Health checks (HTTP, TLS)
-
-Code Quality
-------------
-
-The code quality isn't the greatest/top tier. All code lives in the "main" package and should be moved at some point.
-
-Regardless, it is meant to be simple and easy to understand.
-
-Configuration
--------------
-
-### Modes
-
-#### Redirect
-
-Standard redirect functionality
-
-#### Download Mapping
-
-Uses the `dl_map` configuration variable to enable mapping of paths to new paths.
-
-Think symlinks, but in a generated file.
-
-### Mirrors
-Mirror targets with trailing slash are placed in the yaml configuration file.
-
-### Example YAML
-```yaml
-# GeoIP Database Path
-geodb: GeoLite2-City.mmdb
-
-# Comment out to disable
-dl_map: userdata.csv
-
-# LRU Cache Size (in items)
-cacheSize: 1024
-
-# Server definition
-# Weights are just like nginx, where if it's > 1 it'll be chosen x out of x + total times
-# By default, the top 3 servers are used for choosing the best.
-# server = full url or host+path
-# weight = int
-# optional: latitude, longitude (float)
-servers:
-  - server: armbian.12z.eu/apt/
-  - server: armbian.chi.auroradev.org/apt/
-    weight: 15
-    latitude: 41.8879
-    longitude: -88.1995
-````
-
-## API
-
-`/status`
-
-Meant for a simple health check (nginx/etc can 502 or similar if down)
-
-`/reload`
-
-Flushes cache and reloads configuration and mapping. Requires reloadToken to be set in the configuration, and a matching token provided in `Authorization: Bearer TOKEN`
-
-`/mirrors`
-
-Shows all mirrors in the legacy (by region) format
-
-`/mirrors.json`
-
-Shows all mirrors in the new JSON format. Example:
-
-```json
-[
-  {
-    "available":true,
-    "host":"imola.armbian.com",
-    "path":"/apt/",
-    "latitude":46.0503,
-    "longitude":14.5046,
-    "weight":10,
-    "continent":"EU",
-    "lastChange":"2022-08-12T06:52:35.029565986Z"
-  }
-]
-```
-
-`/mirrors/{server}.svg`
-
-Magic SVG path to show badges based on server status, for use in dynamic mirror lists.
-
-`/dl_map`
-
-Shows json-encoded download mappings
-
-`/geoip`
-
-Shows GeoIP information for the requester
-
-`/region/REGIONCODE/PATH`
-
-Using this magic path will redirect to the desired region:
-
-* NA - North America
-* EU - Europe
-* AS - Asia
-
-`/metrics`
-
-Prometheus metrics endpoint. Metrics aren't considered private, thus are exposed to the public.
