+You may find that you need to use an external TeX package. A derivation for such package has to provide the contents of the "texmf" directory in its output and provide the appropriate `tlType` attribute (one of `"run"`, `"bin"`, `"doc"`, `"source"`). Dependencies on other TeX packages can be listed in the attribute `tlDeps`.
 
-You may find that you need to use an external TeX package. A derivation for such package has to provide contents of the "texmf" directory in its output and provide the `tlType` attribute. Here is a (very verbose) example:
+Such derivation must then be listed in the attribute `pkgs` of an attribute set passed to `texlive.combine`, for instance by passing `extraPkgs = { pkgs = [ custom_package ]; };`. Within Nixpkgs, `pkgs` should be part of the derivation itself, allowing users to call `texlive.combine { inherit (texlive) scheme-small; inherit some_tex_package; }`.
+
+Here is a (very verbose) example where the attribute `pkgs` is attached to the derivation itself, which requires creating a fixed point. See also the packages `auctex`, `eukleides`, `mftrace` for more examples.
