+Building
+--------
+
+*NOTE:* Builder depends on `md5sum` and `tar`
+
+1. Copy your `openwrt-ar71xx-generic-zsun-sdreader-kernel.bin` and
+   `openwrt-ar71xx-generic-zsun-sdreader-rootfs-squash.bin` to `data/` folder
+2. Run `./makefirmware`
+
+Flashing
+--------
+
+*NOTE:* Flasher depends on `smbclient` and `curl`
+
+*NOTE:* Update package is rebuilt on every flash, if you don't like this
+behaviour, comment out `. ./makefirmware` file and change `UPDATEFILE` variable
+
+*NOTE:* This is not really idiotproof
+
+1. Run `./flashfirmware`
+2. ...
+3. PROFIT!
