+# summer 🌞 🏖
+
+Utility to detect accidental data corruption (e.g. bitrot, storage media
+problems).  Not intended to detect malicious modification.
+
+Checksums are written to/read from each file's extended attributes.
+
+
+## Status
+
+summer is still under active development. The user interface and on-disk
+format may change in backwards-incompatible ways.
+
+
+## Install
+
+```
+go install blitiri.com.ar/go/summer@latest
+```
+
+
+## Example
+
+The most common use case is to run `summer update`, which writes checksums for
+new or modified files, and verifies the checksums of the files which have not
+been modified.
+
+The `-x` flag stops summer from crossing filesystem boundaries (for each of
+the given paths).
+
+```
+sudo summer -x update /home /etc /usr
+```
+
+## Contact
+
+If you have any bug reports, questions, comments or patches please send them
+to summer@alb.ar.
