 ====== Crypto - Chia - CLI - Farm - Farming on many machines ======
+Run a harvester on each machine, without having to run a full node, wallet, and farmer on each one.
+This keeps the system simpler, uses less bandwidth, space, CPU, and also keeps the keys safer.
+This should also make the overall farming process quicker and more efficient when replying to challenges.

+----
+===== On Main PC =====
+==== Shut down Chia on the main computer ====
+<code bash>
+chia stop -d all
+</code>
+----
+==== Find the IP address on the main computer ====
+<code bash>
+ip a
+</code>
+----
+==== Make a copy of the main machine CA directory ====
+The CA directory is located in **~/.chia/mainnet/config/ssl/ca**.
+<WRAP info>
+**NOTE:** Copy the CA file.
+This file can be shared via USB stick, or through a network copy to each harvester.
+The new ssl/ca directory must be copied with each version of chia-blockchain.
+</WRAP>
+<WRAP important>
+**WARNING:**  Do not copy the entire config/ssl directory from one machine to another.
+Each harvester must have a different set of TLS certificates for your main machine to recognize it as different harvesters.
+</WRAP>
+----
+===== In the new Harvester =====
+==== Install Chia ====
+<WRAP info>
+**NOTE:**  Use the regular 24 word mnemonic key from the main PC.
+</WRAP>
+----
+==== Shut down Chia ====
+<code bash>
+chia stop -d all
+</code>
+----
+==== Modify Chia Config ====
+Edit the ~/.chia/mainnet/config/config.yaml file.
+Search for **enable_upnp**:
+<file bash ~/.chia/mainnet/config/config.yaml>
+enable_upnp: true
+</file>
+and change to
+<file bash ~/.chia/mainnet/config/config.yaml>
+enable_upnp: false
+</file>
+----
+Search for **harvester:** and the **farmer_peer** section:
+<file bash ~/.chia/mainnet/config/config.yaml>
+harvester:
+  farmer_peer:
+    host: localhost
+</file>
+and change the **localhost** to the IP address of the main PC.
+<file bash ~/.chia/mainnet/config/config.yaml>
+harvester:
+  farmer_peer:
+    host: 192.168.1.51
+</file>
+<WRAP info>
+**NOTE:**  The **192.168.1.51** is the IP address of the main PC.
+</WRAP>
+----
+==== Initialize Chia ====
+<code bash>
+chia init -c [directory]
+</code>
+<WRAP info>
+**NOTE:**  This creates a new certificate signed by the CA of the main machine.
+  * **[directory]** is the **copy** of the main machine CA directory and its network location. <WRAP important>
+**WARNING:** DO NOT replace the /ca directory on the harvester with this copy of the CA from the main machine!
+  * Place the copy of the main machine /ca directory into a temp directory on the harvester.
+  * The harvester will use these files temporarily.
+  * This temporary directory can then be deleted.
+</WRAP>
+For example, assuming the main PC CA was placed into \main_ca:
+<code bash>
+chia init -c \main_ca
+</code>
+</WRAP>
+----
+===== Start Chia on the main PC =====
+<code bash>
+chia start farmer
+</code>
+----
+===== Start the new harvester =====
+On the new PC.
+<code bash>
+chia start harvester -r
+</code>
+<WRAP info>
+**NOTE:**  The new harvester may take up to 20 minutes to start the sync process.
+It will make a full copy of the blockchain to get to normal sync.
+Ensure that firewall rules allow the harvester to connect to the main machine.
+</WRAP>
+----
+===== Check the new harvester is working =====
+On the main PC:
+  * Navigate to the **Farm** tab.
+  * At the bottom select **Hide Advanced Options**.
+  * The **Your Harvester Network** should show additional Node IDs for each harvester.
+<WRAP info>
+**NOTE:**  Another method to check:
+On the main PC **Farm** tab:
+  * **Last Attempted Proof**:  The number of plots on the harvester will also be included in the **Plots Passed Filter** total.
+</WRAP>
+----
+===== Create Plots =====
+New plots can now be created on the new machine.
+<code bash>
+chia plots create -f farmer_key -p pool_key
+</code>
+<WRAP info>
+**NOTE:**
+  * **farmer_key**:  From the main machine.
+  * **pool_key**:  From the main machine.
+Plots can also be copied over.
+Farming will only happen once full sync is completed.
+</WRAP>
+<WRAP info>
+**NOTE:**  After creating a plot, check everything is working correctly:
+<code bash>
+chia plots check
+</code>
+</WRAP>
