 Some notes on how to build NavCoin Core in Unix.
 
 (for OpenBSD specific instructions, see [build-openbsd.md](build-openbsd.md))
 
-Note
----------------------
-Always use absolute paths to configure and compile navcoin and the dependencies,
-for example, when specifying the path of the dependency:
 
-	../dist/configure --enable-cxx --disable-shared --with-pic --prefix=$BDB_PREFIX
+## Building in Ubuntu 18.04
 
-Here BDB_PREFIX must be an absolute path - it is defined using $(pwd) which ensures
-the usage of the absolute path.
+You can easily build the dependencies by running the [NavCoin dev tools script here](https://github.com/NAVCoin/navcoin-dev-tools/blob/master/ubuntu-18.04-navcoin-core-dev-setup.sh).
 
-To Build
