 Improvements to clangd
 ----------------------
 
-- Background indexing is on by default
-
-  When using clangd, it will build an index of your code base (all files listed
-  in your compile database). This index enables go-to-definition,
-  find-references, and even code completion to find symbols across your project.
-
-  This feature can consume a lot of CPU. It can be disabled using the
-  ``--background-index=false`` flag, and respects ``-j`` to use fewer threads.
-  The index is written to ``.clangd/index`` in the project root.
-
-- Contextual code actions
-
-  Extract variable, expand ``auto``, expand macro, convert string to raw string.
-  More to come in the future!
-
-- Clang-tidy warnings are available
-
-  These will be produced for projects that have a ``.clang-tidy`` file in their
-  source tree, as described in the :doc:`clang-tidy documentation <clang-tidy>`.
-
-- Improved diagnostics
-
-  Errors from headers are now shown (on the #including line).
-  The message now indicates if fixes are available.
-  Navigation between errors and associated notes is improved (for editors that
-  support ``Diagnostic.relatedInformation``).
-
-- Suggested includes
-
-  When a class or other name is not found, clangd may suggest to fix this by
-  adding the corresponding ``#include`` directive.
-
-- Semantic highlighting
-
-  clangd can push syntax information to the editor, allowing it to highlight
-  e.g. member variables differently from locals. (requires editor support)
-
-  This implements the proposed protocol from
-  https://github.com/microsoft/vscode-languageserver-node/pull/367
-
-- Type hierachy
-
-  Navigation to base/derived types is possible in editors that support the
-  proposed protocol from
-  https://github.com/microsoft/vscode-languageserver-node/pull/426
-
-- Improvements to include insertion
-
-  Only headers with ``#include``-guards will be inserted, and the feature can
-  be disabled with the ``--header-insertion=never`` flag.
-
-  Standard library headers should now be inserted more accurately, particularly
-  for C++ other than libstdc++, and for the C standard library.
-
-- Code completion
-
-  Overloads are bundled into a single completion item by default. (for editors
-  that support signature-help).
-
-  Redundant const/non-const overloads are no longer shown.
-
-  Before clangd is warmed up (during preamble build), limited identifier- and
-  index-based code completion is available.
-
-- Format-on-type
-
-  A new implementation of format-on-type is triggered by hitting enter: it
-  attempts to reformat the previous line and reindent the new line.
-  (Requires editor support).
-
-- Toolchain header detection
-
-  Projects that use an embedded gcc toolchain may only work when used with the
-  corresponding standard library. clangd can now query the toolchain to find
-  these headers.
-  The compilation database must correctly specify this toolchain, and the
-  ``--query-driver=/path/to/toolchain/bin/*`` flag must be passed to clangd.
-
-- Miscellaneous improvements
-
-  Hover now produces richer Markdown-formatted text (for supported editors).
-
-  Rename is safer and more helpful, though is still within one file only.
-
-  Files without extensions (e.g. C++ standard library) are handled better.
-
-  clangd can understand offsets in UTF-8 or UTF-32 through command-line flags or
-  protocol extensions. (Useful with editors/platforms that don't speak UTF-16).
-
-  Editors that support edits near the cursor in code-completion can set the
-  ``textDocument.completion.editsNearCursor`` capability to ``true``, and clangd
-  will provide completions that correct ``.`` to ``->``, and vice-versa.
