+## Design
+
+* Supported OSes - as per our supported platform policy, we strive for support
+  on all of the platforms that we have CI for. Some platforms do not have the
+  same backwards compatibility guarantees, but we hope the community can step in
+  where needed to make the support more robust.
+* `requirements.txt` is how users have been defining dependencies for a long
+  time. We support this to support legacy usecases or package managers that we
+  don't support directly. Any additional information that we need will be
+  retrieved from the SimpleAPI during the `bzlmod` extension evaluation phase.
+  Then it will be written to the `MODULE.bazel.lock` file for future reuse. We
+  have plans to support `uv.lock` file directly. `uv` is recommended for
+  generating a fully locked `requirements.txt` file and we do provide a rule for
+  it.
+* The `py_binary`, `py_test` rules should scale to large monorepos and we work
+  hard to minimize the work done during analysis and build phase. What is more,
+  the space requirements for should be minimal, so we strive to use symlinks
+  rather than extracting wheels at build time. This means that for different
+  configurations of the same build, we are not extracting the wheel multiple
+  times thus scaling better over the time. From `2.0` onwards we are creating a
+  virtual env for each target by creating an actual minimal virtual environment
+  using symlinks. We plan on creating the traditional `site-packages` layout in
+  the future by default.
+* Support for standards - we strive to first implement any standards needed
+  within `rules_python` and this has resulted in a few PEPs supported within
+  pure starlark - PEP440, PEP509.
+
+Common misconceptions:
+* `rules_python` has to keep backwards compatibility with `google3`. Whilst this
+  might have been true in the past, `rules_python` is an open source project and
+  any compatibility needs should come from the community - we have no
+  requirement to keep this compatibility and are allowed to make our decisions.
+  However, we do want to keep backwards compatibility as long as possible to not
+  upset users with never ending migrations.
+* `rules_python` is not caching pip downloads. With 2.0, we use Bazel's
+  downloader by default and rely on bazel to provide the repository caching
+  mechanisms. This means that for simpler setups this should result in
+  transparent and scalable caching with the most recent bazel versions unless
+  there are issues in the bazel itself.
