 Small web server to send Wake-on-LAN requests to its local network
 
 ## Features
@@ -6,16 +7,19 @@ Small web server to send Wake-on-LAN requests to its local network
 - Binary includes everything except config
 
 ## Installation
-Run `go install git.ulra.eu/adro/miniwol@latest`, resulting in a binary `~/go/bin/miniwol`.
-Move this binary to e.G. `/usr/bin/miniwol` to run it like any command.
+Option 1: Run `go build` in this folder after cloning, resulting in a binary `miniwol` in the current directory.
 
-Examples include a simple systemd service to have it start automatically.
+Option 2: Run `go get git.ulra.eu/adro/miniwol`, resulting in a binary in TODO.
+
+Put the resulting binary in a place like `/usr/bin/miniwol` if you wish to run it like any command,
 
 ## Usage
-Add an empty config. The program uses, in order of priority, `./config.toml`, `./config/config.toml` and `/etc/miniwol/config.toml`. Make sure miniwol can write to it as all persistant data is saved here.
+Add an empty config, the program checks, in order of priority, for `./config.toml`, `./config/config.toml` and `/etc/miniwol/config.toml`. Make sure miniwol can write to it.
 
-Set a password using `miniwol setpass <password>`. This will also add any missing defaults to the config.
+Set a password and write its hash to the config using `miniwol setpass <password>`. This will also add the other default fields to the config.
 
-Run the webserver using `miniwol` or `miniwol web` .
+Configure the devices you want to be able to wake up as per the [example](./example/config.toml).
 
-Sessions are in-memory. Restarting the webserver clears all sessions.
+Now you can run the webserver using `miniwol` or `miniwol web` .
+
+Sessions are simply stored in memory. In case you need to, you can clear all sessions by just restarting the webserver.
