+building and installation
+-------------------------
+
+To build and install the website, use the following commands:
+
+```
+make clean install
+```
+
+The website is built automatically into the *public/* directory.
+
+You can also add a number of variables, to modify the installation process.
+
+```
+# install http files into this directory
+HTTPDIR=/tmp/zblog
+# give all files to this owner after copy
+OWNER != id -u
+# give all files to this group after copy
+GROUP != id -g
+# set this mode on all directories
+DIRMODE = 554
+# set this mode on all files
+FILEMODE = 444
