-Mail-in-a-Box
-=============
+(Power) Mail-in-a-Box
+=====================
+
+## Installation
+
+- **PRE-REQUISITES:** Debian 10 (Buster) or Ubuntu 20.04 LTS fresh installation
+
+Update packages:
+```sh
+sudo apt update
+sudo apt full-upgrade
+```
+
+Make sure that the `en_US.UTF-8` locale exists and is set as primary (this depends on the image you use)
+```sh
+sudo apt install locales
+sudo dpkg-reconfigure locales
+```
+
+Install Power-Mail-in-a-Box (short link)
+```sh
+curl -L https://dvn.pt/powermiab | sudo bash
+```
+
+If that doesn't work:
+```sh
+curl https://raw.githubusercontent.com/ddavness/power-mailinabox/master/setup/bootstrap.sh | sudo bash
+```
+
+## Current Version: v0.52.POWER.0 (Tracking v0.52)
+
+This is a fork of MiaB (duh), hacked and tuned to my needs:
+
+✅ - **Done**
+
+👨‍💻 - **Not there yet, but soon!**
+
+💤 - **I did not begin this part yet!**
+
+- ✅ Support for Debian AND Ubuntu 20.04 LTS;
+
+- ✅ Native support for SMTP relays (For example: SendGrid);
+
+- ✅ Bumped the bootstrap and jQuery dependencies' versions - and we've got a brand new admin panel now!
+
+- ✅ Per-domain `nginx` configuration: Custom pages will no longer have their pages defaulting to the MiaB services (`/admin`, `/mail`, etc.);
+
+- ✅ Updated NextCloud to the latest version available;
+
+- ✅ Performing backups immediately from the admin panel (independently from the daily schedule);
+
+- 👨‍💻 Encrypting backups using user-provided PGP keys;
+
+- 👨‍💻 Integrate a WKD server (Web Key Directory) for PGP keys;
+
+- 💤 Restricting access to the admin panel to certain IP's?
+
+- 💤 Customizing MTA names? (because privacy)
+
+### Ideas section:
+
+- 💤 Ability to download the backups from the admin panel;
+
+- 💤 Possibility of making some services optional (if they require more software to be installed) on setup?
+
+- - For example, one might simply not use NextCloud/Munin at all, and they're there... just wasting resources.
+
+- 💤 AXFR Transfers (for secondary DNS) using TSIG?
+
+- 💤 Expand DNS record options?
+
+- 💤 More complete webmail configuration via the admin panel/plugin management?
+
+- 💤 Expand the TOTP Two-Factor-Authentication for the webmail?
+
+- - Maybe U2F one day, too, but I don't have a capable device for this just yet...
+
+- 💤 Anything else I might need to use;
+
+All in all, I think I should rename this to something like "Central [Clown Computing](https://www.urbandictionary.com/define.php?term=clown%20computing)", since I'm trying to cram as many services as possible into that poor machine (Spending 5$ is better than spending 10$)
