+## lintcheck
+`cargo lintcheck` will build and run clippy on a fixed set of crates and generate a log of the results.  
+You can `git diff` the updated log against its previous version and 
+see what impact your lint made on a small set of crates.  
+If you add a new lint, please audit the resulting warnings and make sure 
+there are no false positives and that the suggestions are valid.
+
+Refer to the tools [README] for more details.

 **Note:** `-Wclippy::all` is always enabled by default, unless `-Aclippy::all`
 is explicitly specified in the options.
+
+### Fix mode
+You can run `./lintcheck/target/debug/lintcheck --fix` which will run Clippy with `-Zunstable-options --fix` and
+print a warning if Clippys suggestions fail to apply (if the resulting code does not build).  
+This lets us spot bad suggestions or false positives automatically in some cases.  
+
+Please note that the target dir should be cleaned afterwards since clippy will modify 
+the downloaded sources which can lead to unexpected results when running lintcheck again afterwards.
