+The purpose of this document is to describe the steps one must perform to run
+an "untrusted" rippled validator on an existing network.
+
+# Vocabulary
+
+- rippled node - A single running instance of rippled
+- Validator - A rippled node that validates transactions
+- Untrusted validator - A validator that is not included in the UNL of other validators on the network
+
+# Binary installation
+
+This document assumes that you are using Ubuntu 14.04.
+
+1. [Install & configure a rippled validator](rippled-validator.html)
+
+2. Stop rippled if it is currently running
+
+        $ sudo service rippled stop
+
+3. Add core validator IP addresses of the network you want to connect to to rippled.cfg
+
+  For example the following IP addresses are the current Altnet core validators:
+
+        [ips_fixed]
+        54.92.66.122 51235
+        54.67.72.173 51235
+        52.16.66.76 51235
+        54.93.66.235 51235
+        52.74.67.18 51235
+        52.64.9.71 51235
+        54.207.20.165 51235
+        54.172.212.33 51235
+        52.11.28.194 51235
+        54.94.245.104 51235
+        54.65.200.22 51235
+        52.1.205.132 51235
+
+4. Add core validator validation public keys to rippled.cfg.
+
+  For example the following keys are the current Altnet core validators' validation public keys:
+
+        [validators]
+        n9LnZ1AiyHmytkhLUr89dmL76uxZLzzyregvQVZFkVfqEQTCpg7B
+        n9LJWexXc9wxzUKWZe4faTS4N9DUba3jNsByERZSa8MJc2bhCF7c
+        n9MnXUt5Qcx3BuBYKJfS4fqSohgkT79NGjXnZeD9joKvP3A5RNGm
+        n9LxyXSSrTZ482ceep9WGQnT2nknfzFMFgNL4wMjTUn3SfF3rhtS
+        n9MTPLhEEjxcWHfqsXQhFoSUKaqYvU4E7B4yke39EMFm2DhFr43F
+        n9Lw3j7THPhKLz2uDqBBWwyxHQC1Foyr3M6JeWCVyu7uhnhL6HA5
+        n9L2XLFvcdriK34bCNXexzKMVcsZ9i4UG9J4pykR5c3J8gvBB6fw
+        n9JCK3M4ci7b1XRq2wr1Ckd1HNq3Cg7NWrWiKyzJa4R5J489QGer
+        n9LXZBs2aBiNsgBkhVJJjDX4xA4DoEBLycF6q8zRhXD1Zu3Kwbe4
+        n9Kk6U5nSF8EggfmTpMdna96UuXWAVwSsDSXRkXeZ5vLcAFk77tr
+        n9J1voqeu6iZQiLXaMofLeMbv8mbPskJWGYRtjdo8rmpvNdQRyEn
+        n9KuCFBLq2GD4vJtoL3tebQJbhcHSd7tMqFM1x9bPK9wSagPJdd1
+        
+5. Adjust the validation quorum value in rippled.cfg
+
+  This sets the minimum of trusted validations a ledger must have before the server considers it fully validated. Note that if you are validating, your validation counts.
+
+  For example a validation quorum for a new Altnet validator could be set to
+
+        [validation_quorum]
+        10
+
+6. Start rippled untrusted validator
+
+        $ sudo service rippled start
+
+The new untrusted validator will first sync with the existing network then start proposing and validating new transactions.
+
+See [Creating a Trusted Rippled Validator](rippled-trusted-validator.html) on how to become a trusted validator on the network.
