+3. Launch hugo in development mode: `hugo -w server`
+4. Navigate to `http://localhost:1313/`: you should see aptly website
+5. Update documentation, most of the time editing Markdown is all you need.
+6. Page in browser should reload automatically as you make changes to source files.
+
+We're always looking for new contributions to [FAQ](https://www.aptly.info/doc/faq/), [tutorials](https://www.aptly.info/tutorial/),
+general fixes, clarifications, misspellings, grammar mistakes!
+
+### Your First Code Contribution
+
+Please follow [next section](#development-setup) on development process. When change is ready, please submit PR
+following [PR template](.github/PULL_REQUEST_TEMPLATE.md).
+
+Make sure that purpose of your change is clear, all the tests and checks pass, and all new code is covered with tests
+if that is possible.
+
+## Development Setup
+
+This section describes local setup to start contributing to aptly source.
+
+### Go & Python
+
+You would need `Go` (latest version is recommended) and `Python` 2.7.x (3.x is not supported yet).
+
+If you're new to Go, follow [getting started guide](https://golang.org/doc/install) to install it and perform
+initial setup. With Go 1.8+, default `$GOPATH` is `$HOME/go`, so rest of this document assumes that.
+
+Usually `$GOPATH/bin` is appended to your `$PATH` to make it easier to run built binaries, but you might choose
+to prepend it or to skip this test if you're security conscious.
+
+### Forking and Cloning
+
+As Go is using repository path in import paths, it's better to clone aptly repo (not your fork) at default location:
+
+    mkdir -p ~/go/src/github.com/aptly-dev
+    cd ~/go/src/github.com/aptly-dev
+    git clone git@github.com:aptly-dev/aptly.git
+    cd aptly
+
+For main repo under your GitHub user and add it as another Git remote:
+
+    git remote add <user> git@github.com:<user>/aptly.git
+
+That way you can continue to build project as is (you don't need to adjust import paths), but you would need
+to specify your remote name when pushing branches:
+
+    git push <user> <your-branch>
+
+### Dependencies
+
+You would need some additional tools and Python virtual environment to run tests and checks, install them with:
+
+    make prepare dev system/env
+
+This is usually one-time action.
+
+### Building
+
+If you want to build aptly binary from your current source tree, run:
+
+    make install
+
+This would build `aptly` in `$GOPATH/bin`, so depending on your `$PATH`, you should be able to run it immediately with:
+
+    aptly
+
+Or, if it's not on your path:
+
+    ~/go/bin/aptly
+
+### Unit-tests
+
+aptly has two kinds of tests: unit-tests and functional (system) tests. Functional tests are preferred way to test any
+feature, but some features are much easier to test with unit-tests (e.g. algorithms, failure scenarios, ...)
+
+aptly is using standard Go unit-test infrastructure plus [gocheck](http://labix.org/gocheck). Run the unit-tests with:
+
+    make test
+
+### Functional Tests
+
+Functional tests are implemented in Python, and they use custom test runner which is similar to Python unit-test
+runner. Most of the tests start with clean aptly state, run some aptly commands to prepare environment, and finally
+run some aptly commands capturing output, exit code, checking any additional files being created and so on. API tests
+are a bit different, as they re-use same aptly process serving API requests.
+
+The easiest way to run functional tests is to use `make`:
+
+    make system-test
+
+This would check all the dependencies and run all the tests. Some tests (S3, Swift) require access credentials to
+be set up in the environment. For example, it needs AWS credentials to run S3 tests (they would be used to publish to S3).
+If credentials are missing, tests would be skipped.
+
+You can also run subset of tests manually:
+
+    system/run.py t04_mirror
+
+This would run all the mirroring tests under `system/t04_mirror` folder.
+
+Or you can run tests by test name mask:
+
+    system/run.py UpdateMirror*
+
+Or, you can run specific test by name:
+
+    system/run.py UpdateMirror7Test
+
+Test runner can update expected output instead of failing on mismatch (this is especially useful while
+working on new tests):
+
+    system/run.py --capture <test>
+
+Output for some tests might contain environment-specific things, e.g. your home directory. In that case
+you can use `${HOME}` and similar variable expansion in expected output files.
+
+Some tests depend on fixtures, for example pre-populated GPG trusted keys. There are also test fixtures
+captured after mirror update which contain pre-build aptly database and pool contents. They're useful if you
+don't want to waste time in the test on populating aptly database while you need some packages to work with.
+There are some packages available under `system/files/` directory which are used to build contents of local repos.
+
+*WARNING*: tests are running under current `$HOME` directory with aptly default settings, so they clear completely
+`~/.aptly.conf` and `~/.aptly` subdirectory between the runs. So it's not wise to have non-dev aptly being used with
+this default location. You can run aptly under different user or by using non-default config location with non-default
+aptly root directory.
+
+### Style Checks
+
+Style checks could be run with:
+
+    make check
+
+aptly is using [golangci-lint](https://github.com/golangci/golangci-lint) to run style checks on Go code. Configuration
+for the linter could be found in [.golangci.yml](.golangci.yml) file.
+
+Python code (system tests) are linted with [flake8 tool](https://pypi.python.org/pypi/flake8).
+
+### Vendored Code
+
+aptly is using Go vendoring for all the libraries aptly depends upon. `vendor/` directory is checked into the source
+repository to avoid any problems if source repositories go away. Go build process will automatically prefer vendored
+packages over packages in `$GOPATH`.
+
+If you want to update vendored dependencies or to introduce new dependency, use [dep tool](https://github.com/golang/dep).
+Usually all you need is `dep ensure` or `dep ensure -update`.
+
+### man Page
+
+aptly is using combination of [Go templates](http://godoc.org/text/template) and automatically generated text to build `aptly.1` man page. If either source
+template [man/aptly.1.ronn.tmpl](man/aptly.1.ronn.tmpl) is changed or any command help is changed, run `make man` to regenerate
+final rendered man page [man/aptly.1](man/aptly.1). In the end of the build, new man page is displayed for visual
+verification.
+
+Man page is built with small helper [\_man/gen.go](man/gen.go) which pulls in template, command-line help from [cmd/](cmd/) folder
+and runs that through [forked copy](https://github.com/smira/ronn) of [ronn](https://github.com/rtomayko/ronn).
+
+### Bash and Zsh Completion
+
+Bash and Zsh completion for aptly reside in the same repo under in [completion.d/aptly](completion.d/aptly) and
+[completion.d/\_aptly](completion.d/_aptly), respectively. It's all hand-crafted.
+When new option or command is introduced, bash completion should be updated to reflect that change.
+
+When aptly package is being built, it automatically pulls bash completion and man page into the package.
+
+## Design

 Download
 --------
 
+To install aptly on Debian/Ubuntu, add new repository to ``/etc/apt/sources.list``::
+
+    deb http://repo.aptly.info/ squeeze main
+
+And import key that is used to sign the release::
+
+    $ apt-key adv --keyserver pool.sks-keyservers.net --recv-keys ED75B5A4483DA07C
+
+After that you can install aptly as any other software package::
+
+    $ apt-get update
+    $ apt-get install aptly
+
+Don't worry about squeeze part in repo name: aptly package should work on Debian squeeze+,
+Ubuntu 10.0+. Package contains aptly binary, man page and bash completion.
+
+If you would like to use nightly builds (unstable), please use following repository::
+
+    deb http://repo.aptly.info/ nightly main
+
 Binary executables (depends almost only on libc) are available for download from `Bintray <http://dl.bintray.com/smira/aptly/>`_.
 
-If you have Go environment set up, you can build aptly from source by running (go 1.1+ required)::
+If you have Go environment set up, you can build aptly from source by running (go 1.10+ required)::

-    mkdir -p $GOPATH/src/github.com/smira/aptly
-    git clone https://github.com/smira/aptly $GOPATH/src/github.com/smira/aptly

-Aptly is using `gom <https://github.com/mattn/gom>`_ to fix external dependencies, so regular ``go get github.com/smira/aptly``
-should work as well, but might fail or produce different result (if external libraries got updated).
+Binary would be installed to ``$GOPATH/bin/aptly``.
 
-If you don't have Go installed (or older version), you can easily install Go using `gvm <https://github.com/moovweb/gvm/>`_.

+# aptly-zsh
+zsh completion for aptly
+
+The zsh completion function and this README were imported from
+[steinymity's repository](https://github.com/steinymity/aptly-zsh).
+
+[Aptly](https://www.aptly.info/) is a great tool to setup Debian APT repositories
+and mirrors. However, it's sometimes hard to remember all the command line
+syntax and names of all options. Therefore I wrote this zsh completion modules
+for aptly.
+
+## License
+
+This project is licensed under the terms of the MIT license. See file `LICENSE`
+for details.
+
+## Installation
+
+Clone/copy the file `_aptly` to a place in your `$fpath` (show with
+`echo $fpath`), or create a new directory and extend the fpath:
+
+    mkdir -p ~/.zsh/functions
+    fpath=(~/.zsh/functions $fpath)
+    editor ~/.zsh/functions/_aptly
+
+To profit most from the provided help messages and completions, make sure that
+your zsh is setup properly. I have tested with the grml-zsh configuration that
+is [available on Github](https://github.com/grml/grml-etc-core/) and on the
+[grml homepage](http://grml.org/zsh/).
+
+## Compatibility
+
+The command line completion was developed based on the manpage of aptly 1.2.0
+(currently in Debian Testing). However, most completions will work on older
+versions (e.g., 0.9.7 in Debian Stable), too.
+
+The completion function completes most arguments and options that can be passed
+to aptly, including mirror/repository/snapshot/publish names. However, not all
+arguments are handled yet. See the next section for known limitations.
+
+## Known Bugs and Limitation
+
+ * Boolean options are always completed with an explicit value `true` or
+   `false`, although omitting the value is implicitly interpreted as `true`.
+ * The source and destination names of copy and move operations must not be the
+   same. This is currently not enforced.
+ * The package query and display format strings are currently not completed.
+ * Endpoints are not completed.
+ * In `publish snapshot` there is no connection between the number of
+   components passed to `-component` and the number of given snapshots to
+   publish. Furthermore, the help text for `endpoint:prefix` disappears
+   after its first possible location.
+ * In `publish switch` the distribution can be set independently of the
+   `endpoint:prefix` (i.e., all published distributions can be combined with
+   all published `endpoint:prefix`).
+ * Neither `publish switch` nor `publish update` check if publish was created
+   from a snapshot or directly from a local repo.
+ * Task commands are not completed. There are no commas added.
+ * `help` won't complete after a sub command (i.e., `aptly mirror list help`).
+ * Probably more, feel free to open issues, and submit patches/merge requests.
