+
+${ME} <installer options>
+
+Valid <installer options> are:
+
+ --install /PATH/TO/INSTALL
+
+ If you 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.
+
+ --auto-update | -u
+
+ Install netdata-updater to cron,
+ to update netdata automatically once per day
+ (can only be done for installations from git)
+
+ --enable-plugin-freeipmi
+ --disable-plugin-freeipmi
+
+ Enable/disable the FreeIPMI plugin.
+ Default: enable it when libipmimonitoring is available.
+
+ --enable-plugin-nfacct
+ --disable-plugin-nfacct
+
+ Enable/disable the nfacct plugin.
+ Default: enable it when libmnl and libnetfilter_acct are available.
+
+ --enable-lto
+ --disable-lto
+
+ Enable/disable Link-Time-Optimization
+ Default: enabled
+
+ --disable-x86-sse
+
+ Disable SSE instructions
+ Default: enabled
+
+ --zlib-is-really-here
+ --libs-are-really-here
+
+ If you get errors about missing zlib,
+ or libuuid but you know it is available,
+ you have a broken pkg-config.
+ Use this option to allow it continue
+ without checking pkg-config.
+
+ --disable-telemetry
+
+ Use this flag to opt-out from our anonymous telemetry progam.
+
+ --disable-go
+
+ Flag to disable installation of go.d.plugin
+
+Netdata will by default be compiled with gcc optimization -O2
+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 (or zlib-devel)
+ uuid-dev (or libuuid-devel)
+
+For the plugins, you will at least need:
+
+ curl, bash v4+, python v2 or v3, node.js
