 ## Introduction
 
-This is a web interface for [OwnTracks](https://github.com/owntracks/recorder), intended to replace the various web pages shipping with the recorder. OwnTracks UI uses Vue.js under the hood.
+This is a web interface for [OwnTracks](https://github.com/owntracks/recorder) built as
+a Vue.js single page application. The recorder itself already ships with some basic web
+pages, this is a more advanced interface with more functionality, all in one place.
+
+![Map features](https://raw.githubusercontent.com/owntracks/frontend/main/docs/images/map-features.png)
+
+## Features
+
+- Last known (i.e. live) locations:

+    speed and regions
+- Location history (data points, line or both)
+- Location heatmap
+- Quickly fit all shown objects on the map into view
+- Display data in a specific date and time range
+- Filter by user or specific device
+- Calculation of distance travelled
+- Highly customisable
 
 ## Installation
 
-### Manual install
-
-Clone the repository and copy `index.html` and the `static/` directory to your server's webroot. The API is expected to be reachable under the same domain as the web interface.
-
 ### Docker
 
-You can launch directly via Docker run like this:
+A pre-built Docker image is available on Docker Hub as [`owntracks/frontend`](https://hub.docker.com/r/owntracks/frontend).
+
+You can start a container directly via `docker run`:
+
 ```console
-$ docker run -d -p 80:80 -e SERVER_HOST=otrecorder-host -e SERVER_PORT=otrecorder-port owntracks/frontend
+$ docker run -d -p 80:80 -e SERVER_HOST=otrecorder-host -e SERVER_PORT=8083 owntracks/frontend
 ```
 
-Or you can use `docker-compose` (if you also run the OwnTracks Recorder with the default compose config, and the service is named `otrecorder`):
+Or you can use `docker-compose` (if you also run the OwnTracks Recorder with the default
+compose config, and the service is named `otrecorder`):
 
 ```yaml
-version: '3'
+version: "3"

+`LISTEN_PORT` enviroment variable - default is 80.
 
-- Enable or disable multiple layers:
+To build the image from source replace `image:` with:
 
-  - Last known (i.e. live) locations:
+```yaml
+build:
+  context: ./owntracks-frontend
+  dockerfile: docker/Dockerfile
+```

-- Node.js based development workflow:
+### CORS-Proxy
 
-  - Webpack
-  - Vue SFCs
-  - Sass
-  - Dependency management with yarn instead of a local copy or unpkg.com
+You can use the [`corsProxy.js`](scripts/corsProxy.js) script to use your production
+instance of OwnTracks for development without making changes to its CORS-Headers:
 
-- Add documentation, at least for the config file
-- Download data for selected date range, user and device as JSON
+```console
+$ npm run cors-proxy
+```
+
+If you have [basic authentication](https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication#Basic_authentication_scheme)
+enabled, create a `.env` file with your credentials:
+
+```text
+OT_BASIC_AUTH_USERNAME=user
+OT_BASIC_AUTH_PASSWORD='P@$$w0rd'
+```
+
+Then run:
+
+```console
+$ env $(cat .env | xargs) npm run cors-proxy
+```
+
+The default host and port it binds to is `0.0.0.0:8888`. Change using the `OT_PROXY_HOST`
+and `OT_PROXY_PORT` environment variables.
+
+Finally update `api.baseUrl` in your config to `"http://0.0.0.0:8888/https://owntracks.example.com"`.
+
+### I18n
+
+This project uses [Vue I18n](https://kazupon.github.io/vue-i18n/). To see missing and
+unused i18n entries, run:
+
+```console
+$ npm run i18n:report
+```
+
+To add a new locale, copy `en-US.json` to `<locale>.json` in [`src/locales`](src/locales)
+and start translating the individual strings. Make sure to [mention the new locale to the docs](docs/config.md#locale)!
+
+For a specific example see commit [`b2edda4`](https://github.com/owntracks/frontend/commit/b2edda410f16633aa6fd9cd4e5250f2031536c7d)
+where German translations were added.

+# Configuration
+
+## Overview
+
+All _custom_ configuation is stored in `window.owntracks.config`,
+which is a regular JavaScript object - so you can use template strings, spread syntax,
+comments and other JS features.
+
+Some of the application state is synced to the URL's query parameters. If a parameter
+exists in the URL query, it takes precedence over the configured value - otherwise the
+configured value will be used and appended to the URL query.
+
+Start with this:
+
+```js
+window.owntracks = window.owntracks || {};
+window.owntracks.config = {};
+```
+
+**WARNING: if your configuration contains private data (most commonly your tile server**
+**access key), make sure to protect access to it properly, e.g. with basic authentication.**

+
+### `api.baseUrl`
+
+Base URL for the recorder's HTTP and WebSocket API. Keep CORS in mind.
+
+- Type: [`String`]
+- Default: current protocol and host
+- Examples:
+  ```js
+  // API requests will be made to https://owntracks.example.com/api/0/...
+  window.owntracks.config = {
+    api: {
+      baseUrl: "https://owntracks.example.com",
+    },
+  };
+  ```
+  ```js
+  // API requests will be made to https://example.com/owntracks/api/0/...
+  window.owntracks.config = {
+    api: {
+      baseUrl: "https://example.com/owntracks/",
+    },
+  };
+  ```
+
+### `api.fetchOptions`
+
+Options for API requests (made with `fetch()`). See [`fetch()` docs on MDN] for details.
+
+You can use this for example to send custom HTTP headers or to include cookies in the request.
+
+- Type: [`Object`]
+- Default: `{}`
+- Example:
+  ```js
+  // Include credentials (e.g. cookies)
+  window.owntracks.config = {
+    api: {
+      fetchOptions: {
+        credentials: "include",
+      },
+    },
+  };
+  ```
+
+### `endDateTime`
+
+Initial end date and time (browser timezone) for fetched data.
+
+- Type: [`Date`]
+- Default: today, 23:59:59

+  window.owntracks.config = {
+    endDateTime: new Date(1970, 1, 1),
+  };
+  ```
+
+### `filters.minAccuracy`
+
+Minimum accuracy in meters for location points to be rendered & included in the travelled distance.
+
+This filter is disabled by default as accuracies can vary across devices an locations, but you're
+encouraged to set it as it can be a simple way to remove outliers and vastly improve the travelled
+distance calculation.
+
+- Type: [`Number`] or `null`
+- Default: `null`
+- Example:
+  ```js
+  // Don't include location points with an accuracy exceeding 100 meters
+  window.owntracks.config = {

+      minAccuracy: 100,
+    },
+  };
+  ```
+
+### `ignorePingLocation`
+
+Remove the `ping/ping` location from the fetched data. This is useful when using the
+`owntracks/recorder` Docker image which has it [enabled for health checks by default](https://github.com/owntracks/recorder/issues/195#issuecomment-304004436).
+
+- Type: [`Boolean`]
+- Default: `true`
+- Example:
+  ```js
+  // Don't ignore ping/ping location. Not sure why you'd do this :)
+  window.owntracks.config = {
+    ignorePingLocation: false,

+- `es-ES` (Castilian Spanish)
+- `fr-FR` (Standard French)
+- `sk-SK` (Standard Slovak)
+- `tr-TR` (Standard Turkish)
+
+Using a locale with non-existent translations is possible and will affect date/time formats, but
+use `en-US` for translations.
+
+- Type: [`String`]
+- Default: `"en-US"`
+
+### `map.attribution`
+
+Attribution for map tiles.
+
+- Type: [`String`] (may contain HTML)

+size of 512x512 need an offset of -1 and for 1024x1024 an offset of -2.
+
+- Type: [`Number`]
+- Default: `0`
+
+### `onLocationChange.fitView`
+
+Whether to re-fit the map's content into view or not when a location update is received.

+### `selectedDevice`
+
+Initial selected device. All devices will be shown by default if `null`. Will be ignored
