 # Installation
 
-## Prerequisites 
-
-You will need a Twitter API key to make BirdsiteLIVE working. First create an **Standalone App** in the [Twitter developer portal](https://developer.twitter.com/en/portal/projects-and-apps) and retrieve the API Key and API Secret Key. 
-
-Please make sure you are using a **Standalone App** API Key and not a **Project App** API Key (that will NOT work with BirdsiteLIVE), if you don't see the **Standalone App** section, you might need to [apply for Elevated Access](https://developer.twitter.com/en/portal/products/elevated) as described in the [API documentation](https://developer.twitter.com/en/support/twitter-api/developer-account).

 ## Server prerequisites
 
 Your instance will need [docker](https://docs.docker.com/engine/install/) and [docker-compose](https://docs.docker.com/compose/install/) installed and working.

 ## About
 
-BirdsiteLIVE is an ActivityPub bridge from Twitter, it's mostly a pet project/playground for me to handle ActivityPub concepts. Feel free to deploy your own instance (especially if you plan to follow a lot of users) since it use a proper Twitter API key and therefore will have limited calls ceiling (it won't scale, and it's by design).
+Bird.makeup is a way to follow Twitter users from any ActivityPub service. The aim is to make tweets appear as native a possible to the fediverse, while being as scalable as possible. The project started from BirdsiteLive, but has now been improved significantly. 
 
-## State of development
+Compared to BirdsiteLive, bird.makeup is:
 
-The code is pretty messy and far from a good state, since it's a playground for me the aim was to understand some AP concepts, not provide a good state-of-the-art codebase. But I might refactor it to make it cleaner. 
+More scalable:
+ - Twitter API calls are not rate-limited
+ - It is possible to split the Twitter crawling to multiple servers
+ - There are now integration tests for the non-official api
+ - The core pipeline has been tweaked to remove bottlenecks. As of writing this, bird.makeup supports without problems more than 20k users. 
+ - Twitter users with no followers on the fediverse will stop being fetched
+
+More native to the fediverse:
+ - Retweets are propagated as boosts
+ - Activities are now "unlisted" which means that they won't polute the public timeline, but they can still be boosted
+ - WIP support for QT
+
+More modern:
+ - Moved from .net core 3.1 to .net 6 which is still supported
+ - Moved from postgres 9 to 15
+ - Moved from Newtonsoft.Json to System.Text.Json
 
 ## Official instance 
 
-You can find an official (and temporary) instance here: [beta.birdsite.live](https://beta.birdsite.live). This instance can disapear at any time, if you want a long term instance you should install your own or use another one. 
+You can find the official instance here: [bird.makeup](https://bird.makeup). If you are an instance admin that prefers to not have tweets federated to you, please block the entire instance. 
 
-## Installation
+Please consider if you really need another instance before spinning up a new one, as having multiple domain makes it harder for moderators to block twitter content. 
-
-I'm providing a [docker build](https://hub.docker.com/r/nicolasconstant/birdsitelive). To install it on your own server, please follow [those instructions](https://github.com/NicolasConstant/BirdsiteLive/blob/master/INSTALLATION.md). More [options](https://github.com/NicolasConstant/BirdsiteLive/blob/master/VARIABLES.md) are also available.
-
-Also a [CLI](https://github.com/NicolasConstant/BirdsiteLive/blob/master/BSLManager.md) is available for adminitrative tasks.

+# Wikidata service
+
+Wikidata is the metadata community behind Wikipedia. See for example
+[Hank Green](https://www.wikidata.org/wiki/Q550996). In his page, there are 
+all the links to his wikipedia pages, and many facts about him. What is 
+particularly useful to us is the twitter username (P2002) and mastodon 
+username (P4033). 
+
+From this information, we can build a feature that suggests to follow the 
+native fediverse account of someone you are trying to follow from Twitter.
+
+The main downside is that those redirect are only for somewhat famous
+people/organisations.
+
+## Goals
+### Being reusable by others
+All this data can be useful to many other fediverse projects: tools 
+for finding interesting accounts to follow, "verified" badge powered by 
+Wikipedia, etc. I hope that by working on improving this dataset, we can
+help other projects thrive. 
+### Being independent of Twitter
+Bird.makeup has to build features in a way that can't be suddenly cut off.
+Building this feature with a "Log in with Twitter" is not viable.
+Wikipedia is independent and outside of Elon's reach.
+
+Also this system supports many other services: TikTok, Reddit, YouTube, etc. 
+Which is really useful to expend the scope of this project while reusing as 
+much work as possible
+### Having great moderation
+
+Wikipedia has many tools to help curate data and remove troll's submissions,
+far better than anything I can build. I much prefer contribute to what
+they are doing than try to compete

-    <h2>FAQ</h2>
-    <h4>Why is there a limit on the node?</h4>
-
-    <p>BirdsiteLIVE rely on the Twitter API to provide high quality content. This API has limitations and therefore limits node capacity.</p>
-
-    <h4>What happen when the node is saturated?</h4>
-
-    <p>
-        When the saturation rate goes above 100% the node will no longer update all accounts every 15 minutes and instead will reduce the pooling rate to stay under the API limits, the more saturated a node is the less efficient it will be.<br />
-        The software doesn't scale, and it's by design.
-    </p>
-
-    <h4>How can I reduce the node's saturation?</h4>
-
-    <p>If you're not on your own node, be reasonable and don't follow too much accounts. And if you can, host your own node. BirdsiteLIVE doesn't require a lot of resources to work and therefore is really cheap to self-host.</p>
