+Valid <installer options> are:

+
+ If your give: --install /opt
+ netdata will be installed in /opt/netdata
+
+ --dont-start-it
+
+ Do not (re)start netdata.
+ Just install it.
+
+ --dont-wait
+
+ Do not wait for the user to press ENTER.
+ Start immediately building it.
+
+ --zlib-is-really-here
+
+ If you get errors about missing zlib,
+ but you know it is available,
+ you have a broken pkg-config.
+ Use this option to allow it continue
+ without checking pkg-config.
+
+Netdata will by default be compiled with gcc optimization -O3
+If you need to pass different CFLAGS, use something like this:
+
+ CFLAGS="<gcc options>" $ME <installer options>
+
+For the installer to complete successfully, you will need
+these packages installed:
+
+ gcc make autoconf automake pkg-config zlib1g-dev
+
+For the plugins, you will at least need:
