* **Describing your issue:** Try to provide as many details as possible. What
exactly goes wrong? *How* is it failing? Is there an error?
"XY doesn't work" usually isn't that helpful for tracking down problems. Always
remember to include the code you ran and if possible, extract only the relevant
parts and don't just dump your entire script. This will make it easier for us to
reproduce the error.

@ -94,39 +95,39 @@ shipped in the core library, and what could be provided in other packages. Our
philosophy is to prefer a smaller core library. We generally ask the following
questions:
* **What would this feature look like if implemented in a separate package?**
Some features would be very difficult to implement externally – for example,
changes to spaCy's built-in methods. In contrast, a library of word
alignment functions could easily live as a separate package that depended on
spaCy — there's little difference between writing `import word_aligner` and
`import spacy.word_aligner`. spaCy v2.0+ makes it easy to implement
[custom pipeline components](https://spacy.io/usage/processing-pipelines#custom-components),
and add your own attributes, properties and methods to the `Doc`, `Token` and
`Span`. If you're looking to implement a new spaCy feature, starting with a
custom component package is usually the best strategy. You won't have to worry
about spaCy's internals and you can test your module in an isolated
environment. And if it works well, we can always integrate it into the core
library later.

* **Would the feature be easier to implement if it relied on "heavy" dependencies spaCy doesn't currently require?**
Python has a very rich ecosystem. Libraries like scikit-learn, SciPy, Gensim or
TensorFlow/Keras do lots of useful things — but we don't want to have them as
dependencies. If the feature requires functionality in one of these libraries,
it's probably better to break it out into a different package.

it's probably better to break it out into a different package.
* **Is the feature orthogonal to the current spaCy functionality, or overlapping?**
spaCy strongly prefers to avoid having 6 different ways of doing the same thing.
As better techniques are developed, we prefer to drop support for "the old way".
However, it's rare that one approach *entirely* dominates another. It's very
common that there's still a use-case for the "obsolete" approach. For instance,
[WordNet](https://wordnet.princeton.edu/) is still very useful — but word
vectors are better for most use-cases, and the two approaches to lexical
semantics do a lot of the same things. spaCy therefore only supports word
vectors, and support for WordNet is currently left for other packages.

* **Do you need the feature to get basic things done?** We do want spaCy to be
at least somewhat self-contained. If we keep needing some feature in our
recipes, that does provide some argument for bringing it "in house".

The docs can always use another example or more detail, and they should always
be up to date and not misleading. To quickly find the correct file to edit,
simply click on the "Suggest edits" button at the bottom of a page. To keep
long pages maintainable, and allow including content in several places without
doubling it, sections often consist of partials. Partials and partial directories
are prefixed by an underscore `_` so they're not compiled with the site. For
example:
```pug
+section("tokenization")
+h(2, "tokenization") Tokenization
include _spacy-101/_tokenization
```
So if you're looking to edit the content of the tokenization section, you can
find it in `_spacy-101/_tokenization.jade`. To make it easy to add content
components, we use a [collection of custom mixins](_includes/_mixins.jade),
like `+table`, `+list` or `+code`. For an overview of the available mixins and
components, see the [styleguide](https://spacy.io/styleguide).

## Publishing spaCy extensions and plugins
We're very excited about all the new possibilities for **community extensions**
and plugins in spaCy v2.0, and we can't wait to see what you build with it!
* An extension or plugin should add substantial functionality, be
**well-documented** and **open-source**. It should be available for users to download
and install as a Python package – for example via [PyPi](http://pypi.python.org).
