+### Building BerkeleyDB
+
+BerkeleyDB is only necessary for the wallet functionality. To skip this, pass
+`--disable-wallet` to `./configure` and skip to the next section.
+
+It is recommended to use Berkeley DB 4.8. You cannot use the BerkeleyDB library
+from ports, for the same reason as boost above (g++/libstd++ incompatibility).
+If you have to build it yourself, you can use [the installation script included
+in contrib/](/contrib/install_db4.sh) like so:
+
+```shell
+./contrib/install_db4.sh `pwd`
+```
+
+from the root of the repository. Then set `BDB_PREFIX` for the next section:
+
+```shell
+export BDB_PREFIX="$PWD/db4"
