+# Contributing
+
+Thank you for your interest in contributing to this project. This file contains instructions that
+will help you work with the source code.
+
+Please note that if you have any questions or difficulties, you can reach the maintainer through
+GitHub Issues. Filing an issue is the preferred method for reporting bugs or issues with the
+development tool configuration for this project.
+
+If you'd like to suggest a small change, you can do that by directly creating a
+[Pull Request](https://docs.github.com/en/pull-requests). For larger changes, you are encouraged to
+file an issue first, so we can discuss the change before you spend too much time implementing it.
+
+Please note that the maintainer, Dave Rolsky (@autarch), mostly works on his FOSS projects in his
+free time, which means on weekends and days off. However, he does not work on these things _every_
+weekend, so it may be a little while before you get a response to your issue or PR.
+
+If it's been more than 3 weeks since you submitted an issue or PR, feel free to comment on the
+submission to nudge the maintainer, who is probably getting sucked into some new video game and
+spending all his time there.

+## 1.0.5 - 2025-07-20
+
+- Fixed a bug in the handling of the `rust-cache-parameters` input. If anything was specified for
+  this, it would end up providing a broken config to the `Swatinem/rust-cache` action. Reported by
+  @SinTan1729 (Sayantan Santra). GH #46.
+
+## 1.0.4 - 2025-04-12
+
+- Removed validation for the `toolchain` input. The
+  [dtolnay/rust-toolchain](https://github.com/dtolnay/rust-toolchain) accepts a lot of different
+  options that this action wasn't allowing. It's simpler and more flexible to just let that action
+  handle validation. Requested by @axos88 (Akos Vandra-Meyer). GH #42.
+- Removed validation for the `command` input. This allows you to use this action with any `cargo`
+  extension command, like `cargo-deb`. Setting `command` to `both` is still supported and will run
+  the `build` and `test` commands. Requested by @bvaisvil (Benjamin Vaisvil). GH #43.
+
+## 1.0.3 - 2025-02-17
+
+- Fixed a bug when running with a Linux ARM host where the action would use a cached `cross`
+  download for x86-64 Linux (or vice versa). Now the cache key for the `cross` binary includes both
+  the runner's architecture in addition to its OS.
+- This release partially support running on Linxu ARM, but see the `README.md` file for details on
+  this.
+
+## 1.0.2 - 2025-02-16
+
+- Added a new `force-use-cross` input, which does what it says. It will force the use of `cross`
+  even when it is not required for given platform/target combination. Note that this only works on
+  Linux hosts.
+
+## 1.0.1 - 2025-01-20
+
+- Fixed a bug where this action would attempt to use `cross` when compiling for an ARM Linux target

+### Setting Environment Variables
+
+By default, `cross` passes most rust-related environment variables through when it runs `cargo` in a
+Docker image. This means you can simply set an `env` key in the workflow step that uses this action.
+
+```
+- name: Run build command
+  uses: houseabsolute/actions-rust-cross@v1
+  env:
+    CARGO_LOG: debug
+    RUSTFLAGS: "-g"
+  with:
+    command: build
+```
+
+If you want to pass other environment variables through, you will need to configure `cross` to do
+see. See the
+[`cross` docs](https://github.com/cross-rs/cross/blob/main/docs/environment_variables.md#environment-variable-passthrough)
+for more details.

+### Caching
+
+By default, this action will use
+[the `Swatinem/rust-cache@v2` action](https://github.com/Swatinem/rust-cache) to cache compiled
+dependencies for a crate. Note that per the documentation for the `rust-cache` action, it has fairly

+`rust-cache-parameters`, then the `target` input will be appended to the value you specify.
+
+#### Weird Caching Issue with Multiple Crates
+
+In my testing, it seemed like in some cases restoring the cache would delete existing files in a
+`target` directory. This manifested with this sequence of actions:
+
+1. Run `actions-rust-cross` to compile a crate in a top-level directory.
+2. Run `actions-rust-cross` to compile a crate in a subdirectory.
+
+After step 2, the compiled binaries from step 1 were no longer present, _sometimes_. I'm not sure
+exactly what's going on here, but my recommendation is to structure your workflows so that this
+cannot affect you.
+
+For example, if you have multiple crates, each of which builds a binary you want to release, then
+you can avoid this issue by structuring your workflow as follows:
+
+1. Run `actions-rust-cross` to compile crate A.
+2. Run the release steps for crate A.
+3. Run `actions-rust-cross` to compile crate B.
+4. Run the release steps for crate B.
+
+When structured this way, it does not matter if the output of crate A is deleted in step 3.
+
+## Cross-Compiling from Linux ARM Runners
+
+In theory, this should work, and this action does implement some of the necessary work for this.
+However, there are a couple issues with this:
+
+1. As of 2025-02-17, the `cross` project does not publish Linux ARM binary releases. That means that
+   in order to use `cross` on a Linux ARM runner as part of this action, you must set
+   `cross-version` to a more recent commit from the `cross` repo.
+2. There is
+   [a bug in `cross` that means you must use a custom Docker image](https://github.com/cross-rs/cross/issues/1628)
+   when cross-compiling from a Linux ARM runner. See
+   [this other `cross` issue](https://github.com/cross-rs/cross/issues/751) for more details.

+## Linting and Tidying this Code
+
+The code in this repo is linted and tidied with
+[`precious`](https://github.com/houseabsolute/precious). This repo contains a `mise.toml` file.
+[Mise](https://mise.jdx.dev/) is a tool for managing dev tools with per-repo configuration. You can
+install `mise` and use it to run `precious` as follows:
+
+```
+# Installs mise
+curl https://mise.run | sh
+# Installs precious and other dev tools
+mise install
+```
+
+Once this is done, you can run `precious` via `mise`:
+
+```
+# Lints all code
+mise exec -- precious lint -a
+# Tidies all code
+mise exec -- precious tidy -a
+```
+
+If you want to use `mise` for other projects, see [its documentation](https://mise.jdx.dev/) for
+more details on how you can configure your shell to always activate `mise`.
