 # wordy
-Improved word cloud discord bot
+This is the new and improved word cloud discord bot ! 
+
+As opposed to the previous Python version, Wordy starts processing the messages as soon as it joins the server and it's much faster with it ! 
+It also automatically continues to process new messages as they are sent.
+
+*Related Blog article: https://teo-orthlieb.github.io/blog/user-word-cloud/*
+
+## How to run it
+The discord registration step is the same for all bot that you run yourself.
+
+### Register Discord Application

+- add a User Bot to it and paste its Token in token.txt
+- enable SERVER MEMBERS INTENT and MESSAGE CONTENT INTENT in the bot tab
+- invite the bot with https://discord.com/api/oauth2/authorize?client_id=CLIENT_ID&permissions=0&scope=bot%20applications.commands replace CLIENT_ID with the Client ID of your app
+
+### Run it
+- Clone the project wherever you want
+- add the token.txt file at the root of the project
+- Install the necessary tools to compile Rust with https://rustup.rs/
+- With a terminal positionned at the root of the project, run `cargo build --release` to build the project.  
+*Note: this will take a while because it's the first build you do, subsequent builds will be much faster*
