++------+
+
+bldr is a program that builds binary packages from an Everest package. It is intened for system image development.
+
+bldr is compatible with Everest packages. That being said, it's only recommended to build packages designated as bldr compatible.
+
++--------------+
+| Installation |
++--------------+
+
+Copy bldr to a convenient location:
+
+	(user)$ cp bldr PROJECT_DIR
+
+Then, copy bldr.conf to either of the following locations:
+
+	/etc/bldr.conf
+	$HOME/.config/bldr.conf
+	PROJECT_DIR/bldr.conf
+
++-------+
+| Usage |
++-------+
+
+	bldr [-h] [-v] [-b] PACKAGE
+
++-------------------+
+| Building packages |
++-------------------+
+
+	(user)$ ./bldr -b /path/to/package
+
+It is important to provide the full path.
+
+bldr will compile the package, and install it to $BLDR_OUT_DIR/pkgs/PACKAGE_NAME.
+
+$BLDR_OUT_DIR can be defined in bldr.conf.
+
+After a package has been compiled, you can either import the package-agnostic installation script,
+or write your own.
+
++---------------------------+
+| Writing packages for bldr |
++---------------------------+
+
+Everest packages only require slight modification in order to be compatible with bldr.
+
+First, ensure the getsource() function looks similar to this:
+
+	getsource() {
+		command1
+		command2
+		cd ${SOURCES[1]}
+	}
+
+The last command in this function is very important. It MUST be "cd ${SOURCES[1]}", otherwise
+bldr will throw an error when a user attempts to build.
+
+It is safe to assume most people using bldr will be cross compiling packages.
+In this case, ensure the toolchain is being used. Toolchains will always be located
+in $BLDR_OUT_DIR/toolchain.
+
+When configuring a package for compilation, ensure the target triplet matches the
+desired system profile. In the case of "x86-musl":
+
+	TARGET="x86_64-linux-musl"
+
+ALWAYS install bldr packages to $BLDR_OUT_DIR/pkgs/PACKAGE_NAME
+bldr packages must not support system functions.
