+## Joining the JAMI Private Network
+
+These instructions are valid for OS X and Linux hosts, Windows hosts should check the syntax.
+
+Step 1: Get the latest Go-Ethereum client from https://geth.ethereum.org/downloads/
+Step 2: Unzip the contents of the tar archive above to a location on your computer - for the rest of the guide we assume you are on a Linux machine and you have unzipped the contents to /home/jamichain - you can use a different location, in which case please make sure to use it for the rest of the instruction guide
+Step 3: Copy the geth executable (just a file) to /home/jamichain and delete the tar archive and the left-over directory
+Step 4: Inside /home/jamichain create a folder called data
+Step 5: Copy the genesis.json file from this repository into /home/jamichain
+Step 6: Inside the /home/jamichain run the command ./geth --datadir data/ init genesis.json (if the command fails check that the data folder has been created and that you are allowed to execute geth)
+Step 7: Run the command geth --datadir=/home/jamichain/data --syncmode=full --networkid 1551 --rpc --rpcaddr 0.0.0.0 --rpcapi "eth,net,web3,personal,admin" --bootnodes "enode://11ba6d3bfdc29a8afb24dcfcf9a08c8008005ead62756eadb363523c2ca8b819efbb264053db3d73949f1375bb3f03090f44cacfb88bade38bb6fc2cb3d890a5@173.231.120.228:30301" console
+
+The above steps will allow you to sync with the Jami blockchain in read-only mode (i.e. you cannot mine blocks - however you can submit transactions). 
+
+
+## Running as a SystemD Service
+
+If you want to run the Jami blockchain as a SystemD service, you can use the following example file (call it jami.service in your SystemD script directory):
+
+
+[Unit]
+Description=Geth Node
+[Service]
+Type=simple
+ExecStart=/home/geth/geth --datadir=/home/jamichain/data --syncmode=full --networkid 1551 --rpc --rpcaddr 0.0.0.0 --rpcapi "eth,net,web3,personal,admin" --bootnodes "enode://11ba6d3bfdc29a8afb24dcfcf9a08c8008005ead62756eadb363523c2ca8b819efbb264053db3d73949f1375bb3f03090f44cacfb88bade38bb6fc2cb3d890a5@173.231.120.228:30301"
+Restart=always
+User=geth
+[Install]
+WantedBy=multi-user.target
+
+
+Please note that the --rpc, --rpcaddr and --rcpapi are OPTIONAL. You are welcome not to include them if you do not want to access the node via JSON-RPC.
