83+## Development Environment
84+
85+There are two ways to get live compiler feedback while developing Obelisk libraries. For libraries that are dependencies of the `skeleton` application, the easiest way to get feedback is to
86+
87+```bash
88+cd skeleton
89+ob run
90+```
91+
92+This `ob run` session only loads modules that are dependencies of the skeleton and `obelisk-run`. For example, `obelisk-asset` and `obelisk-route` are used by the skeleton.
93+
94+For other libraries like `obelisk-command` you can use `ghcid`. To launch `ghcid` for `lib/command` you can run
95+
96+```bash
97+nix-shell -A obeliskEnvs.obelisk-command --run "cd lib/command && ghcid"
98+```
99+
100+### Building `ob` for testing
101+
102+To re-install `ob` from source globally you can do
103+
104+```bash
105+nix-env -f /path/to/obelisk -iA command
106+```
107+
108+You can also open a shell with the local version of `ob` available on your `$PATH`:
109+
110+```bash
111+nix run -f /path/to/obelisk command
112+```
113+
114+### Hacking on Obelisk from within an Obelisk project
115+
116+`ob` will defer to the version found in your project's `.obelisk/impl` directory. To work on that version specifically:
117+

119+ob thunk unpack ./.obelisk/impl

22+* **(Breaking change)** Backport nixpkgs upgrades to ACME/Let's Encrypt handling so that HTTPS deployments continue to work flawlessly. If your deployment is having trouble renewing [Let's Encrypt](https://letsencrypt.org/) certificates, upgrade to this version.
23+ * **IMPORTANT:** In order to use [Let's Encrypt](https://letsencrypt.org/) you must now accept their [terms of service](https://letsencrypt.org/repository/). To do that, add `terms.security.acme.acceptTerms = true;` to the `import ./.obelisk/impl {` section in your `default.nix`. The new skeleton application may serve as an [example](https://github.com/obsidiansystems/obelisk/blob/4759342ab3570888c027d4c58cb5694cb832d624/skeleton/default.nix#L13).

By default it now behaves like `ob run`/`ob watch`/`ob repl` in that it does *not* pre-build any packages whose `.cabal` or `package.yaml` files are found in the project. To regain the previous behavior, use `ob shell --no-interpret . --interpret backend --interpret common --interpret frontend` from the project root.

11+### How do I declare a new Haskell dependency?
12+
13+Every component of your Obelisk application is a standard [cabal](https://www.haskell.org/cabal/) package. That means declaring new Haskell dependencies simply involves updating the `build-depends` field in the appropriate cabal file (`backend.cabal` for example). By default, Obelisk will use its curated package set to choose which version of each package you get. It's possible that the package you need is not already in the curated set or the curated version isn't the one you want. See [How do I add or override Haskell dependencies in the package set?](#how-do-i-add-or-override-haskell-dependencies-in-the-package-set) for a solution to this.
14+
15+### How do I add or override Haskell dependencies in the package set?
16+
17+To add a Haskell package that doesn't exist in Obelisk's package set or to override the version of a package, use the `overrides` attribute in your project's `default.nix`. For example, to use a specific version of the `aeson` package fetched from GitHub and a specific version of the `waargonaut` package fetched from Hackage, your `default.nix` will look like:
18+
19+```nix
20+# ...
21+project ./. ({ pkgs, ... }: {
22+# ...
23+ overrides = self: super: let
24+ aesonSrc = pkgs.fetchFromGitHub {
25+ owner = "obsidiansystems";
26+ repo = "aeson-gadt-th";
27+ rev = "ed573c2cccf54d72aa6279026752a3fecf9c1383";
28+ sha256 = "08q6rnz7w9pn76jkrafig6f50yd0f77z48rk2z5iyyl2jbhcbhx3";
29+ };
30+ in
31+ {
32+ aeson = self.callCabal2nix "aeson" aesonSrc {};
33+ waargonaut = self.callHackageDirect {
34+ pkg = "waargonaut";
35+ ver = "0.8.0.1";
36+ sha256 = "1zv28np3k3hg378vqm89v802xr0g8cwk7gy3mr77xrzy5jbgpa39";
37+ } {};
38+ };
39+# ...
40+```
41+
42+For further information see [the Haskell section](https://nixos.org/nixpkgs/manual/#users-guide-to-the-haskell-infrastructure) of nixpkgs "Contributors Guide".
43+
44+### How do I extend my Obelisk application with more local packages?
45+
46+If the standard packages (`frontend`, `backend`, and `common`) are not enough, you may add more local packages by defining them with the `packages` attribute in your `default.nix`. The sources of these packages will be automatically loaded by `ob run`/`ob repl`/etc.
47+
48+```nix
49+# ...
50+project ./. ({ pkgs, ... }: {
51+# ...

56+```
57+
58+### How do I use `ob run` over HTTPS?
59+
60+To run your app locally over HTTPS, update the protocol in `config/common/route` to `https`, and then use `ob run` as normal.
61+
62+Obelisk generates a self-signed certificate for running HTTPS so the browser will issue a warning about using an invalid certificate. On Chrome, you can go to `chrome://flags/#allow-insecure-localhost` to enable invalid certificates for localhost.

28+## Overview
29+
30+Obelisk allows you to build high-quality web and mobile applications very quickly using [Reflex](https://reflex-frp.org/). In minutes you can go from an empty directory to an interactive application that works on web, iOS, and Android, all sharing the same Haskell codebase! Obelisk's development environment also enables extremely rapid development and feedback. You can take advantage of Haskell's type system across the frontend and backend boundary. This means changes to your backend that would break your frontend are immediately detected during development and vice versa. Obelisk uses Haskell's compiler to give you a complete "TODO list" of what needs to be updated.
31+
32+Obelisk is targeted primarily at Haskell developers who want to build high-quality web and/or mobile applications in Haskell, without the distractions of manually choosing and integrating technology for every piece of the system.
33+
34+### Who should consider using it?
35+
36+Obelisk assumes basic knowledge of [Haskell](https://www.haskell.org/) and [Reflex/Reflex-DOM](https://reflex-frp.org/), web technologies like [HTML](https://developer.mozilla.org/en-US/docs/Web/HTML) and [CSS](https://developer.mozilla.org/en-US/docs/Web/CSS), and a terminal shell like [Bash](https://en.wikipedia.org/wiki/Bash_(Unix_shell)). Knowledge of [Nix](https://nixos.org/) helps but is not strictly necessary.

194− ```shell
195− cat > hie-bios.sh <<'EOF'
196− #!/usr/bin/env bash
197− source "$HOME/.bash_profile"; # NOTE: Some editors need help finding 'ob' and this assumes that `ob` is made available on your `$PATH` in `.bash_profile`
198− ob internal export-ghci-configuration > "$HIE_BIOS_OUTPUT"
199− EOF
200− chmod +x hie-bios.sh
201− ```
202− * **Note:** In some projects you need to use `ob internal export-ghci-configuration --use-relative-paths` in this script instead. This is known to happen when your project contains symlinks to other packages.
203− * Add `hie.yaml` to the root of your project:
204− ```shell
205− echo 'cradle: { bios: { program: hie-bios.sh } }' > hie.yaml
206− ```
207− * Test the configuration with `ob shell ghcide`. Assuming your project compiles and works with `ghcide` otherwise, this should succeed.

It also assumes that you have Nix correctly set up and that your system is set up to fetch from binary caches instead of building everything on your machine. If you notice any of the commands below takes more than 5 minutes, then caches are not likely enabled.
5+> **Note:** This guide can be completed on a Linux host with Nix installed or a macOS host with Nix installed. Each section is labeled regarding which operating system hosts it supports. When going through the guide, start at the beginning and go through all sections that are supported on your host and merely skip sections that are not supported. The sections for iOS deployments require an iPhone or iPad device and the sections for Android deployments require an Android device. This guide assumes that you have Nix correctly set up and that your system is configured to fetch from binary caches instead of building everything on your machine. If you notice any of the commands below takes more than 5 minutes, then caches are not likely enabled.
