 # e2e-irc
 This is an IRC bouncer that supports end-to-end encryption and is horribly written.
 
-# Setup CWD
-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.
-You also need a .env file in your CWD like this:
+# Configuration
+e2e-irc uses a config file in `~/.config/e2e-irc/config.toml` on linux.
+The configuration file is a toml file with two or three fields:
+- 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
-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
+cargo install --git https://forgejo.vanten-s.com/vanten-s/e2e-irc.git
 ```
 
 # Run
-Then you just run the binary with:
-`cargo run --release`
-or build the project to get a binary
 ```bash
-cargo build --release
-cp target/release/e2e-irc ~/.local/bin/
+e2e-irc [OPTIONS] SERVER
 ```
-and after running that once you can run the program with
-```bash
-e2e-irc
-```
-but you have to have the .env in the CWD
