+## Building Bitcoin
+
+Now we can install the Bitcoin node and daemon software. For safety\'s
+sake, we will install it from source.
+
+First, we install the build dependencies:
+
+    apt install build-essential libtool autotools-dev automake pkg-config bsdmainutils python3 libevent-dev libboost-dev libboost-system-dev libboost-filesystem-dev libboost-test-dev git
+
+Now we can download the Bitcoin source code from the official
+repository:
+
+    git clone https://github.com/bitcoin/bitcoin
+        cd bitcoin
+
+Now, we compile, then install it. Compiling the software will take some
+time.
+
+    ./autogen.sh
+    ./configure
+    make
+    make install
