 To package Dotnet applications, you can use `buildDotnetModule`. This has similar arguments to `stdenv.mkDerivation`, with the following additions:
 
 * `projectFile` is used for specifying the dotnet project file, relative to the source root. These have `.sln` (entire solution) or `.csproj` (single project) file extensions. This can be a list of multiple projects as well. When omitted, will attempt to find and build the solution (`.sln`). If running into problems, make sure to set it to a file (or a list of files) with the `.csproj` extension - building applications as entire solutions is not fully supported by the .NET CLI.
-* `nugetDeps` takes either a path to a `deps.nix` file, or a derivation. The `deps.nix` file can be generated using the script attached to `passthru.fetch-deps`. This file can also be generated manually using `nuget-to-nix` tool, which is available in nixpkgs. If the argument is a derivation, it will be used directly and assume it has the same output as `mkNugetDeps`.

 * `packNupkg` is used to pack project as a `nupkg`, and installs it to `$out/share`. If set to `true`, the derivation can be used as a dependency for another dotnet project by adding it to `projectReferences`.
 * `projectReferences` can be used to resolve `ProjectReference` project items. Referenced projects can be packed with `buildDotnetModule` by setting the `packNupkg = true` attribute and passing a list of derivations to `projectReferences`. Since we are sharing referenced projects as NuGets they must be added to csproj/fsproj files as `PackageReference` as well.

+## Generating and updating NuGet dependencies {#generating-and-updating-nuget-dependencies}
+
+First, restore the packages to the `out` directory, ensure you have cloned
+the upstream repository and you are inside it.
+
+```bash
+$ dotnet restore --packages out
+  Determining projects to restore...
+  Restored /home/lychee/Celeste64/Celeste64.csproj (in 1.21 sec).
+```
+
+Next, use `nuget-to-nix` tool provided in nixpkgs to generate a lockfile to `deps.nix` from
+the packages inside the `out` directory.
+
+```bash
+$ nuget-to-nix out > deps.nix
+```
+Which `nuget-to-nix` will generate an output similar to below
+```
+{ fetchNuGet }: [
+  (fetchNuGet { pname = "FosterFramework"; version = "0.1.15-alpha"; sha256 = "0pzsdfbsfx28xfqljcwy100xhbs6wyx0z1d5qxgmv3l60di9xkll"; })

+
+Finally, you move the `deps.nix` file to the appropriate location to be used by `nugetDeps`, then you're all set!
+
+If you ever need to update the dependencies of a package, you instead do
+
+* `nix-build -A package.fetch-deps` to generate the update script for `package`
+* Run `./result deps.nix` to regenerate the lockfile to `deps.nix`, keep in mind if a location isn't provided, it will write to a temporary path instead
+* Finally, move the file where needed and look at its contents to confirm it has updated the dependencies.
