+=== Removing packages from a collection ===
+If you want to package and install a fresher version of some TeXLive package, you might experience a collision with a package from a scheme or a collection you have installed as a whole. To resolve this issue, remove the package by pname from pkgs.
+Example code:
+    pkgs.texlive.combine {
+      scheme-medium = pkgs.texlive.scheme-medium // {
+        pkgs = pkgs.lib.filter
+          (x: (x.pname != "apxproof"))
+          pkgs.texlive.scheme-medium.pkgs;
+      };
+      apxproof = { pkgs = [(pkgs.runCommand "apxproof" {
+        src = pkgs.fetchurl {
+          url = "https://raw.githubusercontent.com/PierreSenellart/apxproof/1ac14c47b8351b693ca05eec73dca1332a517ac9/apxproof.sty";
+          sha256 = "sha256-XSgtXsOwhMu2Wo4hVp8ZfaPWgjEEg3EBn5/BhD3xkMA=";
+        };
+        passthru = {
+          pname = "apxproof";
+          version = "1.2.3";
+          tlType = "run";
+        };
+      }
+      "
+        mkdir -p $out/tex/latex/apxproof/
+        cp $src $out/tex/latex/apxproof/apxproof.sty
+      ")]; };
+    }
