 # e2e-irc
 This is an IRC bouncer that supports end-to-end encryption and is horribly written.
 
-# Configuration
+# Setup CWD
-e2e-irc uses a config file in `~/.config/e2e-irc/config.toml` on linux.
+To use this you need to build it and in your CWD you need to add two files. One called `secret.gpg` and one called `public.gpg` that are just pgp keys.
-The configuration file is a toml file with two or three fields:
+You also need a .env file in your CWD like this:
-- public_key      the location of the public pgp key
-- secret_key      the location of the secret pgp key
-- passwd          the password of the pgp key
-
-# Usage
-```
-e2e-irc [OPTIONS] SERVER
-
-Encrypted IRC Bouncer
-
-Positional arguments:
-  server                The Address Of The Server The Bouncer Connects To
-
-Optional arguments:
-  -h,--help             Show this help message and exit
-  -p,--port PORT        The Port The Bouncer Binds To
-  --sp,--server-port SERVER_PORT
-                        The TLS Enabled Port Of The Server
-```
-
-# Install
 ```bash
-cargo install --git https://forgejo.vanten-s.com/vanten-s/e2e-irc.git
+SERVER={address of the server you want to connect to (has to support tls)}
+PORT={the port you want the program to bind to and the port that the IRC client should connect to}
+PASSWD={password of your pgp key} # Optional
 ```
 
 # Run
+Then you just run the binary with:
+`cargo run --release`
+or build the project to get a binary
 ```bash
-e2e-irc [OPTIONS] SERVER
+cargo build --release
+cp target/release/e2e-irc ~/.local/bin/
 ```
+and after running that once you can run the program with
+```bash
+e2e-irc
+```
+but you have to have the .env in the CWD
