 ### Run tests with asan
 
-**NOTE**: this sometimes yields harder to read results than the full fuzzer
-
 ```shell
-# For nice symbols tell asan how to symoblize. Note that it doesn't like versioned copies like llvm-symbolizer-3.8
-# export ASAN_SYMBOLIZER_PATH=path to version-less llvm-symbolizer
-# ex
-export ASAN_SYMBOLIZER_PATH=/usr/lib/llvm-3.8/bin/llvm-symbolizer
-
-./configure CC=clang CXX=clang++ CPPFLAGS=-fsanitize=address LDFLAGS=-fsanitize=address
-# make/run tests as usual
+meson setup build -Db_sanitize=address
+meson compile -C build
 ```
 
 ### Debug with GDB
 
 ```
-cd ./util
-../libtool --mode=execute gdb --args ./hb-subset ...
+meson setup build
+meson compile -C build
+meson test --gdb testname
 ```
 
 ### Enable Debug Logging
 
 ```shell
-# make clean if you previously build w/o debug logging
-make CPPFLAGS=-DHB_DEBUG_SUBSET=100
+CPPFLAGS=-DHB_DEBUG_SUBSET=100 meson build
+ninja -C build
 ```
 
-## Build and Test via CMake
-
-Note: You'll need to first install ninja-build via apt-get.
+## Build and Test
 
 ```shell
-meson build && ninja -Cbuild && ninja -Cbuild test
+meson build
+ninja -Cbuild
+ninja -Cbuild test
 ```
 
 ## Test with the Fuzzer
 
 ```shell
-# push your changs to a branch on googlefonts/harfbuzz
-# In a local copy of oss-fuzz, edit projects/harfbuzz/Dockerfile
-# Change the git clone to pull your branch
-
-# Do this periodically
-sudo python infra/helper.py build_image harfbuzz
-
-# Do these to update/run
-sudo python infra/helper.py build_fuzzers --sanitizer address harfbuzz
-sudo python infra/helper.py run_fuzzer harfbuzz hb-subset-fuzzer
