Describe install process and tracker stubs (#231)

* Describe install process and tracker stubs

This should fix #226 and maybe stop #228 from being reported again.

* Give Relan credit for the analytics stubs

 Notable features include:
   * `about:config` support
   * The ability to *attempt* to install a much longer list of add-ons than Mozilla's Fenix version of Firefox accepts. Currently the browser queries [this AMO collection](https://addons.mozilla.org/en-US/firefox/collections/16201230/What-I-want-on-Fenix/) **Most of them will not work**, because they depend on code that Mozilla is still working on writing in `android-components`, but you may attempt to install them. If you don't see an add-on you want, you can [request it](https://github.com/fork-maintainers/iceraven-browser/issues/new).
-  * **No warranties or guarantees of security or updates or even stability**! Note that Iceraven Browser is a mix of "Firefox Nightly" with our own added modifications and shipped with the stable version of GeckoView engine. Hence, the browser may contain bugs introduced upstream. Binaries are currently built automatically by our Github release automation. These binaries are signed with a debug key. When we finally publish this somewhere official like F-droid, we will sign the apks with a proper key suitable for public release. Due to the current way we create the releases and sign them, you may not want to rely on such "alpha" quality software as your primary web browser, as it will have bugs. So, use this browser only if you are comfortable with these limitations/potential risks.

 **Note/Disclaimer:** Iceraven Browser could not exist without the hardworking folks at the Mozilla Corporation who work on the Mozilla Android Components and Firefox projects, but it is not an official Mozilla product, and is not provided, endorsed, vetted, approved, or secured by Mozilla.
 
-In addition, we intend to try to cut down on telemetry and proprietary code to as great of an extent as possible as long as doing so does not compromise the user experience or make the fork too hard to maintain. Right now, webelieve that no telemetry should be being sent to Mozilla anymore, but we cannot guarantee this; data may still be sent. **If you catch the app sending data to Mozilla, Adjust, Leanplum, Firebase, or any other such service, please open an issue!** Presumably data that reaches Mozilla is governed by Mozilla's privacy policy, but as Iceraven Browser is, again **not a Mozilla product**, we can make no promises.

Right now, we believe that no telemetry should be being sent to Mozilla anymore, but we cannot guarantee this; data may still be sent. Because of the way we have implemented this, the app may still appear to contain trackers when analyzed by tools that look for the presence of known tracking libraries. These detected trackers should actually be non-functional substitutes, many of which are sourced [from here](https://gitlab.com/relan/fennecbuild/-/blob/master/fenix-liberate.patch). **If you catch the app actually sending data to Mozilla, Adjust, Leanplum, Firebase, or any other such service, please open an issue!** Presumably any data that reaches Mozilla is governed by Mozilla's privacy policy, but as Iceraven Browser is, again **not a Mozilla product**, we can make no promises.
 
 Iceraven Browser combines the power of Fenix (of which we are a fork) and the spirit of Fennec, with a respectful nod toward the grand tradition of Netscape Navigator, from which all Gecko-based projects came, including the earliest of our predecessors, the old Mozilla Phoenix and Mozilla Firefox desktop browsers.
 
 That said, Iceraven Browser is an independent all-volunteer project, and has no affiliation with Netscape, Netscape Navigator, Mozilla, Mozilla Firefox, Mozila Phoenix, Debian, Debian Iceweasel, Parabola GNU/Linux-libre Iceweasel, America Online, or Verizon, among others. :)  Basically, if you don't like the browser, it's not their fault. :)
 
-## Installation
+## 📥 Installation
 
-[**Download APKs from the Releases Page**](https://github.com/fork-maintainers/iceraven-browser/releases)
+Right now, releases are published as `.apk` files, through Github. You should download and install the appropriate one for your device.
+
+1. **Determine what version you need**. If you have a newer, 64-bit device, or a device with more than 4 GB of memory, you probably want the `arm64-v8a` version. **Any ordinary phone or tablet should be able to use the `armeabi-v7a` version**, but it will be limited to using no more than 4 GB of memory. You almost certainly don't want the `x86` or `x86_64` versions; they are in case you are running Android on a PC.
+
+2. [**Download the APK for the latest release from the Releases page**](https://github.com/fork-maintainers/iceraven-browser/releases). Make sure to pick the version you chose in step 1.
+
+3. **Install the APK**. You will need to enable installation of apps from "unknown" (to Google) sources, and installatiuon of apps *by* whatever app you used to open the downloaded APK (i.e. your browser or file manager). Android will try to dissuade you from doing this, and suggest that it is dangerous. Iceraven is a browser for people who enjoy danger.
+
+4. **Enjoy Iceraven**. Make sure to install the add-ons that are essential for you in the main menu under "Add-Ons". You may want to set Iceraven as your device's default browser app. If you do this, it will be able to provide so-called "Chrome" [custom tabs](https://developers.google.com/web/android/custom-tabs) for other applications, allowing you to use your add-ons there.
