+Package name, config entry name and makefile variable relationship
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In Buildroot, there are some relation between:
+
+* the _package name_, which is the package directory name (and the
+  name of the +*.mk+ file);
+
+* the config entry name that is declared in the +Config.in+ file;
+
+* the makefile variable prefix.
+
+Thus, it is mandatory to keep consistency between all this stuff,
+matching the following rules:
+
+* the _make_ target name will be the _package name_ itself (e.g.:
+  +foo-bar_boo+);
+
+* the config entry is the upper case _package name_ with `.` and `-`
+  characters substituted with `_`, prefixed with +BR2_PACKAGE_+ (e.g.:
+  +BR2_PACKAGE_FOO_BAR_BOO+);
+
+* the +*.mk+ file variable prefix is the upper case _package name_
+  `.` and `-` characters substituted with `_` (e.g.:
+  +FOO_BAR_BOO_VERSION+).

+[[github-download-url]]
+How to add package from github
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If the package has no release version, or its version cannot be
+identified using tag, then the sha1 of the particular commit should be
+used to identify the version (the first 7 characters of the sha1 are
+enough):
+
+------------------------
+FOO_VERSION = 1234567
+FOO_SITE = http://github.com/<user>/<package>/tarball/<branch>
+------------------------
+
+If the package version matches a tag, then this tag should be used to
+identify the version:
+
+------------------------
+FOO_VERSION = v1.0
+FOO_SITE = http://github.com/<user>/<package>/tarball/$(FOO_VERSION)
