-Please describe the problem.
-For hints on what information is helpful, see: https://clangd.llvm.org/troubleshooting.html
-
-If you can, provide a minimal chunk of code that shows the problem (either inline, or attach it if larger).
-
-**Logs**
-
-Please attach the clangd stderr log if you can. (Usually available from the editor)
-If possible, run with `--log=verbose` - note that the logs will include the contents of open files!
-If this is a crash, try to put `llvm-symbolizer` on your PATH per the troubleshooting instructions.
-(If you're using Windows, place the associated PDB file (debug symbols) in the same directory as
-clangd.exe and rerun again. For official releases, download symbols from the
-[release page](https://github.com/clangd/clangd/releases).)

-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and

-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-    9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
