+#Installation
+
+Create a directory for local executables (`~/.local/bin/` is recommended) and add it to `PATH` (add `export PATH="${PATH}:${HOME}/.local/bin"` to your `~/.profile` - it may also be `~/.bash_profile` or `~/.zprofile`), copy the files into that folder.
+
+#dc branch
+
+Using the dc-based branch might be beneficial for systems where `bc` is a `dc` wrapper, `printf` command does not support base convertion, etc.
+
+In short, it is even more portable.
+
+#Usage
+
 ##tohex
 
  * `-l` - output numbers with lowercase characters
