Finally, you can run
```shell
hoogle server -p 8080 --local
hoogle server --local -p 8080
```
and navigate to http://localhost:8080/ for your own local
[Hoogle](https://www.haskell.org/hoogle/).
[Hoogle](https://www.haskell.org/hoogle/). The `--local` flag makes the hoogle
server serve files from your nix store over http, without the flag it will use
`file://` URIs. Note, however, that Firefox and possibly other browsers
disallow navigation from `http://` to `file://` URIs for security reasons,
which might be quite an inconvenience. Versions before v5 did not have this
flag. See
[this page](http://kb.mozillazine.org/Links_to_local_pages_do_not_work) for
workarounds.
For NixOS users there's a service which runs this exact command for you.
Specify the `packages` you want documentation for and the `haskellPackages` set
you want them to come from. Add the following to `configuration.nix`.
```nix
services.hoogle = {
enable = true;
packages = (hpkgs: with hpkgs; [text cryptonite]);
haskellPackages = pkgs.haskellPackages;
};
```
