+
+  You are attempting to install netdata as non-root, but you plan
+  to install it in system paths.
+
+  Please set an installation prefix, like this:
+
+      $PROGRAM ${@} --install /tmp
+
+  or, run the installer as root:
+
+      sudo $PROGRAM ${@}
+
+  We suggest to install it as root, or certain data collectors will
+  not be able to work. Netdata drops root privileges when running.
+  So, if you plan to keep it, install it as root to get the full
+  functionality.

+  You are about to install netdata as a non-root user.
+  Netdata will work, but a few data collection modules that

+
+  If you installing netdata permanently on your system, run

+
+USAGE: ${PROGRAM} [options]
+       where options include:
+
+  --install <path>           Install netdata in <path>. Ex. --install /opt will put netdata in /opt/netdata
+  --dont-start-it            Do not (re)start netdata after installation
+  --dont-wait                Run installation in non-interactive mode
+  --auto-update or -u        Install netdata-updater in cron to update netdata automatically once per day
+  --auto-update-type         Override the auto-update scheduling mechanism detection, currently supported types
+                             are: systemd, interval, crontab
+  --stable-channel           Use packages from GitHub release pages instead of GCS (nightly updates).
+                             This results in less frequent updates.
+  --nightly-channel          Use most recent nightly udpates instead of GitHub releases.
+                             This results in more frequent updates.
+  --disable-go               Disable installation of go.d.plugin.
+  --disable-ebpf             Disable eBPF Kernel plugin (Default: enabled)
+  --disable-cloud            Disable all Netdata Cloud functionality.
+  --require-cloud            Fail the install if it can't build Netdata Cloud support.
+  --enable-plugin-freeipmi   Enable the FreeIPMI plugin. Default: enable it when libipmimonitoring is available.
+  --disable-plugin-freeipmi
+  --disable-https            Explicitly disable TLS support
+  --disable-dbengine         Explicitly disable DB engine support
+  --enable-plugin-nfacct     Enable nfacct plugin. Default: enable it when libmnl and libnetfilter_acct are available.
+  --disable-plugin-nfacct
+  --enable-plugin-xenstat    Enable the xenstat plugin. Default: enable it when libxenstat and libyajl are available
+  --disable-plugin-xenstat   Disable the xenstat plugin.
+  --enable-backend-kinesis   Enable AWS Kinesis backend. Default: enable it when libaws_cpp_sdk_kinesis and libraries
+                             it depends on are available.
+  --disable-backend-kinesis
+  --enable-backend-prometheus-remote-write Enable Prometheus remote write backend. Default: enable it when libprotobuf and
+                             libsnappy are available.
+  --disable-backend-prometheus-remote-write
+  --enable-backend-mongodb   Enable MongoDB backend. Default: enable it when libmongoc is available.
+  --disable-backend-mongodb
+  --enable-lto               Enable Link-Time-Optimization. Default: enabled
+  --disable-lto
+  --disable-x86-sse          Disable SSE instructions. By default SSE optimizations are enabled.
+  --use-system-lws           Use a system copy of libwebsockets instead of bundling our own (default is to use the bundled copy).
+  --zlib-is-really-here or
+  --libs-are-really-here     If you get errors about missing zlib or libuuid but you know it is available, you might
+                             have a broken pkg-config. Use this option to proceed without checking pkg-config.
+  --disable-telemetry        Use this flag to opt-out from our anonymous telemetry progam. (DO_NOT_TRACK=1)
+
+Netdata will by default be compiled with gcc optimization -O2
+If you need to pass different CFLAGS, use something like this:
+
+  CFLAGS="<gcc options>" ${PROGRAM} [options]
+
+If you also need to provide different LDFLAGS, use something like this:
+
+  LDFLAGS="<extra ldflag options>" ${PROGRAM} [options]
+
+or use the following if both LDFLAGS and CFLAGS need to be overriden:
+
+  CFLAGS="<gcc options>" LDFLAGS="<extra ld options>" ${PROGRAM} [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

+
