 # Runs the linters against dendrite
 
 # The linters can take a lot of resources and are slow, so they can be
-# configured using two environment variables:
+# configured using the following environment variables:
 #
 # - `DENDRITE_LINT_CONCURRENCY` - number of concurrent linters to run,
-#   gometalinter defaults this to 8
-# - `DENDRITE_LINT_DISABLE_GC` - if set then the the go gc will be disabled
-#   when running the linters, speeding them up but using much more memory.
+#   golangci-lint defaults this to NumCPU
+# - `GOGC` - how often to perform garbage collection during golangci-lint runs.
+#   Essentially a ratio of memory/speed. See https://github.com/golangci/golangci-lint#memory-usage-of-golangci-lint
+#   for more info.
