+## Introduction
+
+NeoChat is a client for [Matrix](https://matrix.org), the decentralized communication protocol for instant
+messaging. It is a fork of Spectral, using KDE frameworks, most notably [Kirigami](https://invent.kde.org/frameworks/kirigami)
+to provide a convergent experience across multiple platforms.
+
+NeoChat also make use of other KDE Frameworks as well as [libQuotient](https://github.com/quotient-im/libQuotient), a
+Qt-based SDK for the [Matrix Protocol](https://spec.matrix.org/).
+
+![Timeline](https://cdn.kde.org/screenshots/neochat/application.png)
+
+## Features
+
+NeoChat aims to be a fully featured application for the Matrix specification. As such everything in the current stable specification with the notable exceptions
+of VoIP, threads and some aspects of End-to-End Encryption are supported. There are a few other smaller omissions due to the fact that the Matrix spec is constantly
+evolving but the aim remains to provide eventual support for the entire spec.
+
+Due to the nature of the Matrix specification development NeoChat also supports numerous unstable features. Currently these are:
+- Polls - MSC3381
+- Sticker Packs - MSC2545
+- Location Events - MSC3488
 
 ## Get it
 
-A stable release [is available](https://apps.kde.org/neochat) for download for Linux distributions.
+Details where to find stable releases for NeoChat can be found on its [homepage](https://apps.kde.org/neochat).
 
+In addition to the stable builds, unstable nightly builds are available for all platforms. These can be downloaded
+from the [binary factory](https://binary-factory.kde.org/). There are unstable versions for the following platforms
+in addition to stable ones:
+- Android
+- MacOS
+- Windows
 
-Along with the stable release, a Flatpak version is available for the nightly
-version:
+Additionally the nightly Flatpak version can be obtained from the nightly Flatpak repo using the following commands in your terminal:
 
 ```
 flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
@@ -26,42 +53,53 @@ flatpak remote-add --if-not-exists kdeapps --from https://distribute.kde.org/kde
 flatpak install kdeapps org.kde.neochat
 ```
 
-A nightly build is also available for Android in the [KDE nightly F-Droid repo](https://community.kde.org/Android/FDroid)
-and can also directly be downloaded from the [binary factory](https://binary-factory.kde.org/view/Android/job/NeoChat_Nightly_android-arm64/).
+The unstable Android version can also be obtained from the [KDE nightly F-Droid repo](https://community.kde.org/Android/FDroid).
 
-Nightly builds for [Windows](https://binary-factory.kde.org/job/NeoChat_Nightly_win64/), [MacOS](https://binary-factory.kde.org/job/NeoChat_Nightly_macos/) and [AppImages](https://binary-factory.kde.org/job/NeoChat_Nightly_appimage/) can also be downloaded from the [binary factory](https://binary-factory.kde.org/search/?q=neochat).
+## Running
 
-![Timeline](https://cdn.kde.org/screenshots/neochat/application.png)
+Just start the executable in your preferred way - either from the build directory or from the installed location.
 
-## Features
+## Building NeoChat
 
-* Sending messages
-* Sending files from clipboard and filesystem
-* Reply to message (right-click on a message to access menu)
-* Start a private chat (but not encrypted)
-* Show notifications, for the moment there is only a global switch
-to disable it. We plan to implement the configuration part of the
-specification soon.
-* Autocompletion of usernames in chat
-* Emoji picker
-* Basic room setting page
-* Send and accept invitations
-* /rainbow <message> (very important)
-* /me <message>
+The best way to build KDE apps during development is to use `kdesrc-build`. The full instructions for this can be found on
+the KDE community website's get involved section under [development](https://community.kde.org/Get_Involved/development). This
+is primarily aimed at Linux development.
 
-NeoChat is still missing a few features to become a full-featured
-Matrix client (most notably encryption support and video chat support).
-We welcome contributions in this direction.
+For Windows and Android [Craft](https://invent.kde.org/packaging/craft) is the primary choice. There are guides for setting up
+development environments for [Windows](https://community.kde.org/Get_Involved/development/Windows) and [Android](https://develop.kde.org/docs/packaging/android/building_applications/).
+
+## Tests
+
+Tests are in the repository under [autotests](autotests) and should all pass for any contribution.
+
+The project has CI setup to test new commits to the repository. All tests are expected to pass for a merge request to
+be complete.
+
+Current build status
+
+![coverage](https://invent.kde.org/network/neochat/badges/master/pipeline.svg)
+
+Currently the number of tests is limited, but growing. If anyone wants to help improve this, those
+contributions would be especially welcome.
+
+## Contributing
+
+As is the case throughout the KDE ecosystem contributions are welcome from all. The code base is managed in the
+[NeoChat repository](https://invent.kde.org/network/neochat) of the KDE Gitlab instance.

 ## Contact
 
-You can reach the maintainers at [#neochat:kde.org](https://matrix.to/#/#neochat:kde.org), if you are already on Matrix.
-Development happens in http://invent.kde.org/network/neochat (not in GitHub).
+The best place to reach the maintainers is on the KDE Matrix instance in the NeoChat channel, [#neochat:kde.org](https://matrix.to/#/#neochat:kde.org).

+ * upon a start and finish break point. This is to provide better convergence where
+ * generally the delegate will need to fill all or most the screen when thin but
+ * should max out in size and only fill a lower percentage of the screen when wide.
+ *
+ * @note While the main intended usage is to start with a high percentage when the parentWidth
+ *       is small and transition to a lower one when large, the math is setup for the
+ *       general case so any combination of parameters works.
