+
+A Minetest mod @code{foo} is named @code{minetest-foo} -- the author
+name from ContentDB is not included, unless required to resolve a name
+collision.
+
+Sometimes, it might be unclear what the version of a Minetest mod is.
+For example, ContentDB and the importer reports 2020-01-01, but
+according to the forums the version is 2.1.  Usually, in these cases the
+version on ContentDB is the newest and intended for distribution. As
+such, you can use the version from ContentDB without any special
+comments.
+
+@c Currently it's always checked out from git, but in principle
+@c tarballs could be used.
+
+Even though the source code is often checked out from version control,
+it is not necessary to use @code{git-version} or @code{hg-version}: the
+releases on ContentDB are formal releases; in fact they are upstream's
+official source of Minetest packages and they are not mutated in-place.
+
+@c Example (zip): mods by TenPlus1
+@c Example (git): basic_materials, ethereal
+While ContentDB provides the source code of packages in zip form, it is
+recommended not to use these, because users can and do delete old
+versions.  Likewise, sometimes the maintainer initially did tag versions
+but later stops doing so, breaking @command{guix refresh -u}.  As such,
+it is recommended not to use git tags in @code{origin} records and
+instead refer to the commit directly.
+
+The dependency information from ContentDB is usually correct.  However,
+sometimes to actually use a Minetest mod, an additional non-declared
+Minetest mod is required.  For example, to craft an item from a mod
+@code{minetest-basic-materials} in non-creative mode, an item from the
+mod @code{minetest-moreores} is required.  In such situations, it is
+recommended to add @code{minetest-moreores} to the inputs of
+@code{minetest-basic-materials}.  The dependencies go into
+@code{propagated-inputs}.
