+# e2e-irc
+This is an IRC bouncer that supports end-to-end encryption and is horribly written.
+
+# 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
+cargo install e2e-irc
+```
+
+# Run
+```bash
+e2e-irc [OPTIONS] SERVER
