+To regenerate the dockerfile, run `php Dockerfile.php > Dockerfile`
+To regenerate headers, run: `docker buildx build . -o .`
+To generate headers without checking (useful for getting a copy of the header file to identify any errors), comment out the last line of process.php
+
+Symbols syntax:
+- `x`: export symbol x
+- `#x`: export definition x
+- `//...`: Comment
+
+Modifiers (after a symbol):
+- `zts` / `nts`: Only import symbol on thread-safe/non-thread-safe
+- `<x.y` / `>x.y` / `<=x.y` / `>=x.y` / `=x.y` / `!=x.y`: Only import symbol on a given PHP version
+
+To add a new symbol:
+- Check what PHP versions it's defined in and if it's in an `#ifdef` (specifically `ZTS`) and add modifiers as appropriate
+- Add to bottom of symbols.txt *unless* required by another symbol (in which case list it above)
+- Regenerate headers and ensure all builds pass
+- Commit updated headers
+
+To add a new PHP version:
+- Add to Dockerfile.php
+- Regenerate dockerfile
+- Regenerate headers
+- Add modifier for any removed symbols to exclude them
+- Add modifier for any newly required symbols (ex. members of common classes)
