 ## Developing
 
-At time of writing, `codecov-rs` requires the nightly compiler for niceties such as `#[feature(trait_alias)]` in the library itself and some convenient `mockall` behavior in tests.
+At time of writing, `codecov-rs` requires the nightly compiler for niceties such as `#[feature(trait_alias)]` in the library itself.
 
 `codecov-rs` aims to serve as effective documentation for every flavor of every format it supports. To that end, the following are greatly appreciated in submissions:
 - Thorough doc comments (`///` / `/**`). For parsers, include snippets that show what inputs look like
-- Granular, in-module unit tests (`mockall` may help)
+- Granular, in-module unit tests
 - Integration tests with real-world samples (that are safe to distribute; don't send us data from your private repo)
 
+Large sample test reports are checked in using [Git LFS](https://git-lfs.com/) in `core/fixtures/**/large` directories (e.g. `core/fixtures/pyreport/large`). Tests and benchmarks may reference them so installing it yourself is recommended.
+
 The `examples/` directory contains runnable commands for developers including:
 - `parse_pyreport`: converts a given pyreport into a SQLite report
 - `sql_to_pyreport`: converts a given SQLite report into a pyreport (report JSON + chunks file)
 
-Considering following suit for your own new feature.
+You can run an example with `cargo run --example <example> <arguments>`. Consider following suit for your own new feature.
 
 Install lint hooks with `pip install pre-commit && pre-commit install`.
