+# π
 
 Experimental and extremely weird XMPP client made with Go. No solicitors.
 
 pi is currently pre-pre-pre-pre alpha software which you should not use right now.
 
-pi uses [Fyne](https://fyne.io) for the frontend.
+pi uses [Fyne](https://fyne.io) for the frontend and uses the [Oasis SDK](https://github.com/jjj333-p/oasis-sdk) for XMPP functionality.
+
+pi is an extremely opinionated client. It aims to have as little extra windows as possible, instead using alt-menus to perform many of the actions you'd see in a typical client.
+
+
+## διαμόρφωση
+(configuration)
+
+In order to use pi, you currently have to create a `pi.json` file in the working directory of the executable. Here is how one looks like:
+
+```json
+{
+    "Host":"example.com:5222",
+    "User":"user@example.com",
+    "Password":"123456",
+    "DisplayName":"user",
+    "NoTLS":false,
+    "StartTLS":true,
+    "Mucs":["room@muc.example.com"]}
+```
+
+Edit this file as necessary.
+
+Currently joining and saving DM tabs is not supported, nor is getting avatars, reactions, encryption of media embed.
+
+As of writing, pi supports basic message sending and receiving, replies and file upload.
+
+
+## να χτίσω 
+(building)
+
+To build pi, you will need the latest version of Go, at least 1.21. You can grab it [here](https://go.dev).
+
+The build instructions are very simple. Simply clone the repo, fetch the repositories and build the program:
+
+Here is a summary of the commands you would need to use to build and run the program:
+```bash
+git clone https://github.com/sunglocto/pi
+cd pi
+go mod tidy
+go build .
+vim pi.json
+./pi
+```
+
+Static executable snapshots are also provided for GNU/Linux systems.
