+NOTES FOR SLASH/ DEVELOPERS
+===========================
+
+Run the varnish-cache test suite with SLASH/
+--------------------------------------------
+
+.. _`varnishd_args_prepend`: https://github.com/varnishcache/varnish-cache/commit/ad3fa105b35654f768cdd684b13241d05b3e661f
+
+Using the `varnishd_args_prepend`_ macro, most VTCs from the
+varnish-cache test suite can be run with buddy/fellow in place of the
+built-in storage engines. The exception are tests which explicitly
+define a storage named ``s0`` and those which check for counters of
+the malloc/umem stevedores.
+
+Invocation example::
+
+  ./varnishtest \
+  -D varnishd_args_prepend='-E/tmp/lib/varnish/vmods/libvmod_slash.so -sfellow,fellow.stv,10MB,1MB,64KB' \
+  -ki -j20 $(grep -EL -- '(-ss0|SM..s0)' tests/[b-x]*vtc) 2>&1 | tee slash_log
+
+As of 2023-07, some tests fill fail on the assertion that no objects
+are leaked::
+
+  ***  v1    debug|Info: Child (3823881) said varnishd: buddy.c:1359: buddy_fini: Assertion `freemap_space(map) == map->size' failed.
+
+These cases are not necessarily a SLASH/ error and still need to be
+investigated.
