+Hacking
+=======
+The following is a quickstart guide for developing `cheat`.
+
+## 1. Install system dependencies
+Before you begin, you must install a handful of system dependencies. The
+following are required, and must be available on your `PATH`:
+
+- `git`
+- `go` (>= 1.17 is recommended)
+- `make`
+
+The following dependencies are optional:
+- `docker`
+- `pandoc` (necessary to generate a `man` page)
+
+## 2. Install utility applications
+Run `make setup` to install `scc` and `revive`, which are used by various
+`make` targets.
+
+## 3. Development workflow
+After your environment has been configured, your development workflow will
+resemble the following:
+
+1. Make changes to the `cheat` source code.
+2. Run `make test` to run unit-tests.
+3. Fix compiler errors and failing tests as necessary.
+4. Run `make`. A `cheat` executable will be written to the `dist` directory.
+5. Use the new executable by running `dist/cheat <command>`.
+6. Run `make install` to install `cheat` to your `PATH`.
+7. Run `make build-release` to build cross-platform binaries in `dist`.
+8. Run `make clean` to clean the `dist` directory when desired.
+
+You may run `make help` to see a list of available `make` commands.
+
+### Developing with docker
+It may be useful to test your changes within a pristine environment. An
+Alpine-based docker container has been provided for that purpose.
+
+If you would like to build the docker container, run:
+```sh
+make docker-setup
+```
+
+To shell into the container, run:
+```sh
+make docker-sh
+```
+
+The `cheat` source code will be mounted at `/app` within the container.
+
+If you would like to destroy this container, you may run:
+```sh
+make distclean
+```

INSTALLING.md

@@ -0,0 +1,77 @@
+Installing
+==========
+`cheat` has no runtime dependencies. As such, installing it is generally
+straightforward. There are a few methods available:
+
+### Install manually
+#### Unix-like
+On Unix-like systems, you may simply paste the following snippet into your terminal:
+
+```sh
+cd /tmp \
+  && wget https://github.com/cheat/cheat/releases/download/4.2.5/cheat-linux-amd64.gz \
+  && gunzip cheat-linux-amd64.gz \
+  && chmod +x cheat-linux-amd64 \
+  && sudo mv cheat-linux-amd64 /usr/local/bin/cheat
+```
+
+You may need to need to change the version number (`4.2.5`) and the archive
+(`cheat-linux-amd64.gz`) depending on your platform.
+
+See the [releases page][releases] for a list of supported platforms.
+
+#### Windows
+TODO: community support is requested here. Please open a PR if you'd like to
+contribute installation instructions for Windows.
+
+### Install via `go install`
+If you have `go` version `>=1.17` available on your `PATH`, you can install
+`cheat` via `go install`:
+
+```sh
+go install github.com/cheat/cheat/cmd/cheat@latest
+```
+
+### Install via package manager
+Several community-maintained packages are also available:
+
+Package manager  | Installing
+---------------- | -----------
+[brew][]         | `brew install cheat`
+[docker][]       | `alias cheat='docker run --rm bannmann/docker-cheat'`
+[nix][]          | `nix-env -iA nixos.cheat`
+[snap][]         | `snap install cheat`
+
+<!--[pacman][]       |-->
+
+## Configuring
+Three things must be done before you can use `cheat`:
+1. A config file must be generated
+2. [`cheatpaths`][cheatpaths] must be configured
+3. [Community cheatsheets][community] must be downloaded
+
+On first run, `cheat` will run an installer that will do all of the above
+automatically. After the installer is complete, it is strongly advised that you
+view the configuration file that was generated, as you may want to change some
+of its default values (to enable colorization, change the paginator, etc).
+
+### conf.yml ###
+`cheat` is configured by a YAML file that will be auto-generated on first run.
+
+By default, the config file is assumed to exist on an XDG-compliant
+configuration path like `~/.config/cheat/conf.yml`. If you would like to store
+it elsewhere, you may export a `CHEAT_CONFIG_PATH` environment variable that
+specifies its path:
+
+```sh
+export CHEAT_CONFIG_PATH="~/.dotfiles/cheat/conf.yml"
+```

+Binaries are available to install from [the releases page](https://github.com/alecthomas/chroma/releases).
-go get -u github.com/alecthomas/chroma/cmd/chroma
+
+The CLI can be used as a preprocessor to colorise output of `less(1)`,
+see documentation for the `LESSOPEN` environment variable.
+
+The `--fail` flag can be used to suppress output and return with exit status
+1 to facilitate falling back to some other preprocessor in case chroma
+does not resolve a specific lexer to use for the given file. For example:
+
+```shell
+export LESSOPEN='| p() { chroma --fail "$1" || cat "$1"; }; p "%s"'
 ```
 
+Replace `cat` with your favourite fallback preprocessor.
+
+When invoked as `.lessfilter`, the `--fail` flag is automatically turned
+on under the hood for easy integration with [lesspipe shipping with
+Debian and derivatives](https://manpages.debian.org/lesspipe#USER_DEFINED_FILTERS);
+for that setup the `chroma` executable can be just symlinked to `~/.lessfilter`.

 ## What's missing compared to Pygments?
 
 - Quite a few lexers, for various reasons (pull-requests welcome):
     - Pygments lexers for complex languages often include custom code to
-      handle certain aspects, such as Perl6's ability to nest code inside
+      handle certain aspects, such as Raku's ability to nest code inside
       regular expressions. These require time and effort to convert.
     - I mostly only converted languages I had heard of, to reduce the porting cost.
 - Some more esoteric features of Pygments are omitted for simplicity.
