 vichan - A lightweight and full featured PHP imageboard.
 ========================================================
 
-**Vichan has next to no active development<!--, however you can still pay for support. Basic support costs $40/hr, and is only payable in BTC. New features depend on what you want. Email COPYPASTE &lt;AT&gt; KITTENS &lt;DOT&gt; PH if you're interested&mdash;Vichan forks such as OpenIB are included in this offer-->.**
+**Please do not contact Fredrick Brennan in regards to vichan issues.**
+
+As of 29 August 2022 it supports PHP8.1.
 
 About
 ------------
 vichan is a free light-weight, fast, highly configurable and user-friendly
 imageboard software package. It is written in PHP and has few dependencies.
 
-*Security problems can be reported to the development team: DEVELOPMENT \<AT\> VICHAN \<DOT\> NET.*
-	
-While there is currently no active development besides fixing security problems, we don't exclude the possibility to refactor the code in order to meet today's standards and continue our work from the point where [@czaks](https://github.com/czaks) retired in 2017.
-Before this milestone is achieved though, we strongly urge you to consider other imageboard packages. It is the opinion of the vichan development team that no new vichan imageboards should be deployed at the moment, and other imageboard packages used instead.
-
-For support, feel free to join our [IRC channel](https://webchat.6an.org/?channels=vichan-dev) at irc.6an.org.
-
 Some documentation may be found on our [wiki](https://github.com/vichan-devel/vichan/wiki). (feel free to contribute)

+The `php-fpm` process runs containerized.
+The php application always uses `/var/www` as it's work directory and home folder, and if `/var/www` is bind mounted it
+is necessary to adjust the path passed via FastCGI to `php-fpm` by changing the root directory to `/var/www`.
+This can achieved in nginx by setting the `fastcgi_param SCRIPT_FILENAME` to `/var/www/$fastcgi_script_name;`
+
+The default docker compose settings are intended for development and testing purposes.
+The folder structure expected by compose is as follows
+
+```
+<vichan-project>
+└── local-instances
+    └── 1
+        ├── mysql
+        └── www
+```
+The vichan container is by itself much less rigid.
+
+
+Use `docker compose up --build` to start the docker compose.
+Use `docker compose up --build -d php` to rebuild just the vichan container while the compose is running. Useful for development.
