+To build modules in our package we've used something like this:
+```
+$ build --platform=UefiLessonsPkg/UefiLessonsPkg.dsc \
+        --module=UefiLessonsPkg/HelloWorld/HelloWorld.inf \
+        --arch=X64 \
+        --buildtarget=RELEASE \
+        --tagname=GCC5
+```
+
+This is kinda long string. Let's simplify it.
+
+First we can omit `module` option from the command and always compile our package entirely with all its modules:
+
+```
+$ build --platform=UefiLessonsPkg/UefiLessonsPkg.dsc \
+        --arch=X64 \
+        --buildtarget=RELEASE \
+        --tagname=GCC5
+```
+
+When we initiate our environment with:
+```
+. edk2setup.sh
+```
+`Conf` directory is created in the edk2 folder. This directory is populated with a bunch of files.
+Also the `CONF_PATH` environment variable is created which points to the newly created `Conf` folder.
+
+Right now we are interested in the `Conf/target.txt` file.
+By default it has many comments (lines that start with `#` symbol) and is prepopulated with these values:
+```
+ACTIVE_PLATFORM       = EmulatorPkg/EmulatorPkg.dsc
+TARGET                = DEBUG
+TARGET_ARCH           = IA32
+TOOL_CHAIN_CONF       = Conf/tools_def.txt
+TOOL_CHAIN_TAG        = VS2015x86
+BUILD_RULE_CONF = Conf/build_rule.txt
+```
+
+We can put all our build command options in this file to simplify our everyday life.
+```
+ACTIVE_PLATFORM       = UefiLessonsPkg/UefiLessonsPkg.dsc
+TARGET                = RELEASE
+TARGET_ARCH           = X64
+TOOL_CHAIN_CONF       = Conf/tools_def.txt
+TOOL_CHAIN_TAG        = GCC5
+BUILD_RULE_CONF = Conf/build_rule.txt
+```
+
+After that we could build our package with all its modules with the one single command:
+```
+build
+```
