+# **heck** is a case conversion library
+
+!["I specifically requested the opposite of this."](./no_step_on_snek.png)
+
+This library exists to provide case conversion between common cases like
+CamelCase and snake_case. It is intended to be unicode aware, internally
+consistent, and reasonably well performing.
+
+## Definition of a word boundary
+
+Word boundaries are defined as the "unicode words" defined in the
+`unicode_segmentation` library, as well as within those words in this manner:
+
+1. All underscore characters are considered word boundaries.
+2. If an uppercase character is followed by lowercase letters, a word boundary
+is considered to be just prior to that uppercase character.
+3. If multiple uppercase characters are consecutive, they are considered to be
+within a single word, except that the last will be part of the next word if it
+is followed by lowercase characters (see rule 2).
+
+That is, "HelloWorld" is segmented `Hello|World` whereas "XMLHttpRequest" is
+segmented `XML|Http|Request`.
+
+Characters not within words (such as spaces, punctuations, and underscores)
+are not included in the output string except as they are a part of the case
+being converted to. Multiple adjacent word boundaries (such as a series of
+underscores) are folded into one. ("hello__world" in snake case is therefore
+"hello_world", not the exact same string). Leading or trailing word boundary
+indicators are dropped, except insofar as CamelCase capitalizes the first word.
+
+## Cases contained in this library:
+
+1. CamelCase
+2. snake_case
+3. kebab-case
+4. SHOUTY_SNAKE_CASE
+5. mixedCase
+6. Title Case
+7. SHOUTY-KEBAB-CASE
+
+## Contributing
+
+PRs of additional well-established cases welcome.
+
+This library is a little bit opinionated (dropping punctuation, for example).
+If that doesn't fit your use case, I hope there is another crate that does. I
+would prefer **not** to receive PRs to make this behavior more configurable.
+
+Bug reports & fixes always welcome. :-)
+
+## MSRV
+
+The minimum supported Rust version for this crate is 1.32.0. This may change in
+minor or patch releases, but we probably won't ever require a very recent
+version. If you would like to have a stronger guarantee than that, please open
+an issue.
+
+## License
+
+heck is distributed under the terms of both the MIT license and the
+Apache License (Version 2.0).
+
+See LICENSE-APACHE and LICENSE-MIT for details.

+//! **heck** is a case conversion library.
+//!
+//! This library exists to provide case conversion between common cases like
+//! CamelCase and snake_case. It is intended to be unicode aware, internally,
+//! consistent, and reasonably well performing.
+//!
+//! ## Definition of a word boundary
+//!
+//! Word boundaries are defined as the "unicode words" defined in the
+//! `unicode_segmentation` library, as well as within those words in this
+//! manner:
+//!
+//! 1. All underscore characters are considered word boundaries.
+//! 2. If an uppercase character is followed by lowercase letters, a word
+//! boundary is considered to be just prior to that uppercase character.
+//! 3. If multiple uppercase characters are consecutive, they are considered to
+//! be within a single word, except that the last will be part of the next word
+//! if it is followed by lowercase characters (see rule 2).
+//!
+//! That is, "HelloWorld" is segmented `Hello|World` whereas "XMLHttpRequest" is
+//! segmented `XML|Http|Request`.
+//!
+//! Characters not within words (such as spaces, punctuations, and underscores)
+//! are not included in the output string except as they are a part of the case
+//! being converted to. Multiple adjacent word boundaries (such as a series of
+//! underscores) are folded into one. ("hello__world" in snake case is therefore
+//! "hello_world", not the exact same string). Leading or trailing word boundary
+//! indicators are dropped, except insofar as CamelCase capitalizes the first
+//! word.
+//!
+//! ### Cases contained in this library:
+//!
+//! 1. CamelCase
+//! 2. snake_case
+//! 3. kebab-case
+//! 4. SHOUTY_SNAKE_CASE
+//! 5. mixedCase
+//! 6. Title Case
+//! 7. SHOUTY-KEBAB-CASE

+/// ```rust
+/// use heck::TitleCase;
+///
+/// let sentence = "We have always lived in slums and holes in the wall.";
+/// assert_eq!(sentence.to_title_case(), "We Have Always Lived In Slums And Holes In The Wall");
