-For accessing data based on key lookup, the C++ standard library offers `std::set`, `std::map`, `std::multiset` and `std::multimap`.
-These are generally implemented using balanced binary trees so that lookup time has logarithmic complexity.
-That is generally okay, but in many cases a hash table can perform better, as accessing data has constant complexity, on average.
-The worst case complexity is linear, but that occurs rarely and with some care, can be avoided.
+Boost.Unordered offers a catalog of hash containers with different standards compliance levels, performances and intented usage scenarios:

-Also, the existing containers require a 'less than' comparison object to order their elements.
-For some data types this is impossible to implement or isn’t practical.
-In contrast, a hash table only needs an equality function and a hash function for the key.
+**`boost::unordered_set` `boost::unordered_map` `boost::unordered_multiset` `boost::unordered_multimap`**

-With this in mind, unordered associative containers were added to the C++ standard.
-This is an implementation of the containers described in C++11, with some deviations from the standard in order to work with non-C++11 compilers and libraries.
+<ul>Fully conformant implementations of <code>std::unordered_[multi](set|map)</code>,
+but faster and up to the latest revisions of the standard even if you're working in an older version of C++ (heterogeneous lookup,
+<code>try_emplace</code>, <code>contains</code>, etc.)</ul>

+**`boost::unordered_flat_set` `boost::unordered_flat_map`**

-### License
+<ul>The fastest of the lot. Based on open addressing, these containers slightly
+deviate from the standard in exchange for top performance.</ul>

-Distributed under the [Boost Software License, Version 1.0](http://www.boost.org/LICENSE_1_0.txt).
+**`boost::unordered_node_set` `boost::unordered_node_map`**

-### Properties
+<ul>Variations of <code>boost::unordered_flat_(set|map)</code> providing pointer stability.</ul>

-* C++03
-* Header-Only
+**`boost::concurrent_flat_set` `boost::concurrent_flat_map`**

-### Build Status
+<ul>High performance for multithreaded scenarios. Introducing a new non-standard, iterator-free API.</ul>

+## Get the library

-### More information
+Boost.Unordered can be installed in a number of ways:

-* [Ask questions](http://stackoverflow.com/questions/ask?tags=c%2B%2B,boost,boost-unordered)
-* [Report bugs](https://github.com/boostorg/unordered/issues): Be sure to mention Boost version, platform and compiler you're using. A small compilable code sample to reproduce the problem is always good as well.
-* Submit your patches as pull requests against **develop** branch. Note that by submitting patches you agree to license your modifications under the [Boost Software License, Version 1.0](http://www.boost.org/LICENSE_1_0.txt).
-* Discussions about the library are held on the [Boost developers mailing list](http://www.boost.org/community/groups.html#main). Be sure to read the [discussion policy](http://www.boost.org/community/policy.html) before posting and add the `[unordered]` tag at the beginning of the subject line.
+* [Download Boost](https://www.boost.org/users/download/) and you're ready to go (this is a header-only library requiring no building).
+* Using Conan 2: In case you don't have it yet, add an entry for Boost in your `conanfile.txt` (the example requires at least Boost 1.83):
+```
+[requires]
+boost/[>=1.83.0]
+```
+<ul>If you're not using any compiled Boost library, the following will skip building altogether:</ul>

+```
+[options]
+boost:header_only=True
+```
+* Using vcpkg: Execute the command
+```
+vcpkg install boost-unordered
+```
+* Using CMake: [Boost CMake support infrastructure](https://github.com/boostorg/cmake)
+allows you to use CMake directly to download, build and consume all of Boost or
+some specific libraries.
+
+## Support
+
+* Join the **#boost-unordered** discussion group at [cpplang.slack.com](https://cpplang.slack.com/)
+([ask for an invite](https://cppalliance.org/slack/) if you’re not a member of this workspace yet)
+* Ask in the [Boost Users mailing list](https://lists.boost.org/mailman/listinfo.cgi/boost-users)
+(add the `[unordered]` tag at the beginning of the subject line)
+* [File an issue](https://github.com/boostorg/unordered/issues)
