+This directory contains the results of compilation tests. Specifically,
+the results are from testing both the from scratch compilation time and
+relative binary size increases of various features for both the `regex` and
+`regex-automata` crates.
+
+Here's an example of how to run these tests for just the `regex` crate. You'll
+need the `regex-cli` command installed, which can be found in the `regex-cli`
+directory in the root of this repository.
+
+This must be run in the root of a checkout of this repository.
+
+```
+$ mkdir /tmp/regex-compile-test
+$ regex-cli compile-test ./ /tmp/regex-compile-test | tee record/compile-test/2023-04-19_1.7.3.csv
+```
+
+You can then look at the results using a tool like [`xsv`][xsv]:
+
+```
+$ xsv table record/compile-test/2023-04-19_1.7.3.csv
+```
+
+Note that the relative binary size is computed by building a "baseline" hello
+world program, and then subtracting that from the size of a binary that uses
+the regex crate.
