+CONTRIBUTING
 ============
-If you would like to contribute cheetsheets or program functionality, please
-fork this repository, make your changes, and submit a pull request against the
-`master` branch.
+Do you want to contribute to `cheat`? There are a few ways to help:
+
+#### Submit a cheatsheet ####
+Do you have a witty bash one-liner to share? [Open a pull-request][pr] against
+the [cheatsheets][] repository. (The `cheat` executable source code lives in
+[cheat/cheat][cheat]. Cheatsheet content lives in
+[cheat/cheatsheets][cheatsheets].)
+
+#### Report a bug ####
+Did you find a bug? Report it in the [issue tracker][issues]. (But before you
+do, please look through the open issues to make sure that it hasn't already
+ been reported.)
+
+#### Add a feature ####
+Do you have a feature that you'd like to contribute? Propose it in the [issue
+tracker][issues] to discuss with the maintainer whether it would be considered
+for merging.
+
+`cheat` is mostly mature and feature-complete, but may still have some room for
+new features. See [HACKING.md][hacking] for a quick-start guide to `cheat`
+development.
+
+#### Add documentation ####
+Did you encounter features, bugs, edge-cases, use-cases, or environment
+considerations that were undocumented or under-documented? Add them to the
+[wiki][]. (You may also open a pull-request against the `README`, if
+appropriate.)
+
+Do you enjoy technical writing or proofreading? Help keep the documentation
+error-free and well-organized.
+
+#### Spread the word ####
+Are you unable to do the above, but still want to contribute? You can help
+`cheat` simply by telling others about it. Share it with friends and coworkers
+that might benefit from using it.
+
+#### Pull Requests ####
+Please open all pull-requests against the `develop` branch.
 
 
-## Python standards ##
-Python code should conform to [PEP 8][].
-
-
-## Cheatsheet Format ##
-Please pattern your cheatsheets after the following:
-
-```sh
-# To extract an uncompressed archive:
-tar -xvf /path/to/foo.tar
-
-# To create an uncompressed archive:
-tar -cvf /path/to/foo.tar /path/to/foo/
-
-# To extract a .gz archive:
-tar -xzvf /path/to/foo.tgz
-```
-
-If you are submitting a cheatsheet that contains side-by-side columns of text,
-please align the columns using spaces rather than tabs.

+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 +1,79 @@
+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/4.4.2/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 (`4.4.2`) 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  | Package(s)
+---------------- | -----------
+aur              | [cheat][pkg-aur-cheat], [cheat-bin][pkg-aur-cheat-bin]
+brew             | [cheat][pkg-brew]
+docker           | [docker-cheat][pkg-docker]
+nix              | [nixos.cheat][pkg-nix]
+snap             | [cheat][pkg-snap]
+
+<!--[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"
+```

+
+```sh
+cheat -s ssh
+```
+
+To search (by regex) for cheatsheets that contain an IP address:
+
+```sh
+cheat -r -s '(?:[0-9]{1,3}\.){3}[0-9]{1,3}'
+```
+
+Flags may be combined in intuitive ways. Example: to search sheets on the
+"personal" cheatpath that are tagged with "networking" and match a regex:
+
+```sh
+cheat -p personal -t networking --regex -s '(?:[0-9]{1,3}\.){3}[0-9]{1,3}'
+```
 
-Note that, while `cheat` was designed primarily for \*nix system administrators,
-it is agnostic as to what content it stores. If you would like to use `cheat`
-to store notes on your favorite cookie recipes, feel free.
 
 
 Installing
 ----------
-It is recommended to install `cheat` with `pip`:
+For installation and configuration instructions, see [INSTALLING.md][].
 
-```sh
-[sudo] pip install cheat
-```
-
-[Other installation methods are available][installing].
-
-
-Modifying Cheatsheets
----------------------
-The value of `cheat` is that it allows you to create your own cheatsheets - the
-defaults are meant to serve only as a starting point, and can and should be
-modified.
-
-Cheatsheets are stored in the `~/.cheat/` directory, and are named on a
-per-keyphrase basis. In other words, the content for the `tar` cheatsheet lives
-in the `~/.cheat/tar` file.
-
-Provided that you have a `CHEAT_EDITOR`, `VISUAL`, or `EDITOR` environment
-variable set, you may edit cheatsheets with:
-
-```sh
-cheat -e foo
-```
-
-If the `foo` cheatsheet already exists, it will be opened for editing.
-Otherwise, it will be created automatically.
-
-After you've customized your cheatsheets, I urge you to track `~/.cheat/` along
-with your [dotfiles][].
-
-
-Configuring
+Cheatsheets
 -----------
-
-### Setting a DEFAULT_CHEAT_DIR ###
-Personal cheatsheets are saved in the `~/.cheat` directory by default, but you
-can specify a different default by exporting a `DEFAULT_CHEAT_DIR` environment
-variable:
+Cheatsheets are plain-text files with no file extension, and are named
+according to the command used to view them:
 
 ```sh
-export DEFAULT_CHEAT_DIR='/path/to/my/cheats'
+cheat tar     # file is named "tar"
+cheat foo/bar # file is named "bar", in a "foo" subdirectory
 ```
 
-### Setting a CHEATPATH ###
-You can additionally instruct `cheat` to look for cheatsheets in other
-directories by exporting a `CHEATPATH` environment variable:
+Cheatsheet text may optionally be preceeded by a YAML frontmatter header that
+assigns tags and specifies syntax:
 
-```sh
-export CHEATPATH='/path/to/my/cheats'
+```
+---
+syntax: javascript
+tags: [ array, map ]
+---
+// To map over an array:
+const squares = [1, 2, 3, 4].map(x => x * x);
 ```
 
-You may, of course, append multiple directories to your `CHEATPATH`:
+The `cheat` executable includes no cheatsheets, but [community-sourced
+cheatsheets are available][cheatsheets]. You will be asked if you would like to
+install the community-sourced cheatsheets the first time you run `cheat`.
 
-```sh
-export CHEATPATH="$CHEATPATH:/path/to/more/cheats"
+Cheatpaths
+----------
+Cheatsheets are stored on "cheatpaths", which are directories that contain
+cheatsheets. Cheatpaths are specified in the `conf.yml` file.
+
+It can be useful to configure `cheat` against multiple cheatpaths. A common
+pattern is to store cheatsheets from multiple repositories on individual
+cheatpaths:
+
+```yaml
+# conf.yml:
+# ...
+cheatpaths:
+  - name: community                   # a name for the cheatpath
+    path: ~/documents/cheat/community # the path's location on the filesystem
+    tags: [ community ]               # these tags will be applied to all sheets on the path
+    readonly: true                    # if true, `cheat` will not create new cheatsheets here
+
+  - name: personal
+    path: ~/documents/cheat/personal  # this is a separate directory and repository than above
+    tags: [ personal ]
+    readonly: false                   # new sheets may be written here
+# ...
 ```
 
-You may view which directories are on your `CHEATPATH` with `cheat -d`.
+The `readonly` option instructs `cheat` not to edit (or create) any cheatsheets
+on the path. This is useful to prevent merge-conflicts from arising on upstream
+cheatsheet repositories.
 
-### Enabling Syntax Highlighting ###
-`cheat` can optionally apply syntax highlighting to your cheatsheets. To enable
-syntax highlighting, export a `CHEATCOLORS` environment variable:
+If a user attempts to edit a cheatsheet on a read-only cheatpath, `cheat` will
+transparently copy that sheet to a writeable directory before opening it for
+editing.
 
-```sh
-export CHEATCOLORS=true
-```
+### Directory-scoped Cheatpaths ###
+At times, it can be useful to closely associate cheatsheets with a directory on
+your filesystem. `cheat` facilitates this by searching for a `.cheat` folder in
+the current working directory. If found, the `.cheat` directory will
+(temporarily) be added to the cheatpaths.
 
-#### Specifying a Syntax Highlighter ####
-You may manually specify which syntax highlighter to use for each cheatsheet by
-wrapping the sheet's contents in a [Github-Flavored Markdown code-fence][gfm].
+Autocompletion
+--------------
+Shell autocompletion is currently available for `bash`, `fish`, and `zsh`. Copy
+the relevant [completion script][completions] into the appropriate directory on
+your filesystem to enable autocompletion. (This directory will vary depending
+on operating system and shell specifics.)
 
-Example:
+Additionally, `cheat` supports enhanced autocompletion via integration with
+[fzf][]. To enable `fzf` integration:
 
-<pre>
-```sql
--- to select a user by ID
-SELECT *
-FROM Users
-WHERE id = 100
-```
-</pre>
+1. Ensure that `fzf` is available on your `$PATH`
+2. Set an envvar: `export CHEAT_USE_FZF=true`
 
-If no syntax highlighter is specified, the `bash` highlighter will be used by
-default.

-# To skip the HOST'S SSL CERTIFICATE VERIFICATION, you can pass

-# You can control what should be printed via several options:
-  # --headers, -h   Only the response headers are printed.
-  # --body, -b      Only the response body is printed.
-  # --verbose, -v   Print the whole HTTP exchange (request and response).
-  # --print, -p     Selects parts of the HTTP exchange.
-http --verbose PUT httpbin.org/put hello=world
-
-# Print request and response headers:
-  # Character   Stands for
-  # ----------- -------------------
-  # H           Request headers.
-  # B           Request body.
-  # h           Response headers.
-  # b           Response body.
-http --print=Hh PUT httpbin.org/put hello=world
-
-# Let's say that there is an API that returns the whole resource when it
-# is updated, but you are only interested in the response headers to see
-# the status code after an update:
-http --headers PATCH example.org/Really-Huge-Resource name='New Name'
-
-# Redirect from a file:
-http PUT example.com/person/1 X-API-Token:123 < person.json
-
-# Or the output of another program:
-grep '401 Unauthorized' /var/log/httpd/error_log | http POST example.org/intruders
-
-# You can use echo for simple data:
-echo '{"name": "John"}' | http PATCH example.com/person/1 X-API-Token:123
-
-# You can even pipe web services together using HTTPie:
-http GET https://api.github.com/repos/jkbrzt/httpie | http POST httpbin.org/post
-
-# You can use cat to enter multiline data on the terminal:
-cat | http POST example.com
-    <paste>
-    # ^D
-cat | http POST example.com/todos Content-Type:text/plain
-    - buy milk
-    - call parents
-    ^D
-
-# On OS X, you can send the contents of the clipboard with pbpaste:
-pbpaste | http PUT example.com
-
-# Passing data through stdin cannot be combined with data fields specified
-# on the command line:
-echo 'data' | http POST example.org more=data   # This is invalid
-
-
-# AN ALTERNATIVE TO REDIRECTED stdin is specifying a filename (as
-# @/path/to/file) whose content is used as if it came from stdin.
-
-# It has the advantage that THE Content-Type HEADER IS AUTOMATICALLY SET
-# to the appropriate value based on the filename extension. For example,
-# the following request sends the verbatim contents of that XML file with
-# Content-Type: application/xml:
-http PUT httpbin.org/put @/data/file.xml
-
-# Download a file:
-http example.org/Movie.mov > Movie.mov
-
-# Download an image of Octocat, resize it using ImageMagick, upload it
-# elsewhere:
-http octodex.github.com/images/original.jpg | convert - -resize 25% -  | http example.org/Octocats
-
-# Force colorizing and formatting, and show both the request and the
-# response in less pager:
-http --pretty=all --verbose example.org | less -R
-
-# When enabled using the --download, -d flag, response headers are printed
-# to the terminal (stderr), and a progress bar is shown while the response
-# body is being saved to a file.
-http --download https://github.com/jkbrzt/httpie/tarball/master
-
-# You can also redirect the response body to another program while the
-# response headers and progress are still shown in the terminal:
-http -d https://github.com/jkbrzt/httpie/tarball/master |  tar zxf -
-
-# If --output, -o is specified, you can resume a partial download using
-# the --continue, -c option. This only works with servers that support
-# Range requests and 206 Partial Content responses. If the server doesn't
-# support that, the whole file will simply be downloaded:
-http -dco file.zip example.org/file
-
-# Prettified streamed response:
-http --stream -f -a YOUR-TWITTER-NAME https://stream.twitter.com/1/statuses/filter.json track='Justin Bieber'
-
-# Send each new tweet (JSON object) mentioning "Apple" to another
-# server as soon as it arrives from the Twitter streaming API:
-http --stream -f -a YOUR-TWITTER-NAME https://stream.twitter.com/1/statuses/filter.json track=Apple | while read tweet; do echo "$tweet" | http POST example.org/tweets ; done
-
-# Create a new session named user1 for example.org:
-http --session=user1 -a user1:password example.org X-Foo:Bar
-
-# Now you can refer to the session by its name, and the previously used
-# authorization and HTTP headers will automatically be set:
-http --session=user1 example.org
-
-# To create or reuse a different session, simple specify a different name:
-http --session=user2 -a user2:password example.org X-Bar:Foo
-
-# Instead of a name, you can also directly specify a path to a session
-# file. This allows for sessions to be re-used across multiple hosts:
-http --session=/tmp/session.json example.orghttp --session=/tmp/session.json admin.example.orghttp --session=~/.httpie/sessions/another.example.org/test.json example.orghttp --session-read-only=/tmp/session.json example.org
