+1] ### DERO Installation, https://github.com/deroproject/wiki/wiki#dero-installation  
+
+        DERO is written in golang and very easy to install both from source and binary.
+Installation From Source:  
+    Install Golang, minimum Golang 1.10.3 required.
+    In go workspace: go get -u github.com/deroproject/derosuite/...
+    Check go workspace bin folder for binaries.
+    For example on Linux machine following binaries will be created:
+        derod-linux-amd64 -> DERO daemon.
+        dero-wallet-cli-linux-amd64 -> DERO cmdline wallet.
+        explorer-linux-amd64 -> DERO Explorer. Yes, DERO has prebuilt personal explorer also for advance privacy users.
+
+Installation From Binary  
+        Download DERO binaries for ARM, INTEL, MAC platform and Windows, Mac, FreeBSD, OpenBSD, Linux etc. operating systems.  
+https://github.com/deroproject/derosuite/releases
+
+2] ### Running DERO Daemon  
+./derod-linux-amd64 
+
+3] ### Running DERO Wallet (Use local or remote daemon) 
+./dero-wallet-cli-linux-amd64 --remote  
+https://wallet.dero.io [Web wallet]
+
+4] ### DERO Mining Quickstart
+Run miner with wallet address and no. of threads based on your CPU.  
+./dero-miner --mining-threads 4 --daemon-rpc-address=http://explorer.dero.io:20206 --wallet-address dERoXHjNHFBabzBCQbBDSqbkLURQyzmPRCLfeFtzRQA3NgVfU4HDbRpZQUKBzq59QU2QLcoAviYQ59FG4bu8T9pZ1woERqciSL  
+
+NOTE: Miners keep your system clock sync with NTP etc.  
+Eg on linux machine: ntpdate pool.ntp.org
