+# HACKING 
+
+## cutting releases
+
+### goals
+
+Cutting a release should be a boring, rote process with as little excitement as
+possible. Following the processes in this document, we should be able to cut a
+release at any time without worrying about producing bad artifacts. Our process
+should let us resolve build issues without affecting library users.
+
+### branching
+
+1. The `main` branch represents the next major version of the library.
+2. Previous major versions should be tracked using `v0.x`, `v1.x`, `v2.x`, used
+   for backporting changes as necessary.
+3. Libraries should generate a `latest` release using, e.g.,
+   `marvinpinto/action-automatic-releases` on changes to the `main` branch.
+
+### tag and release process
+
+1. Pick a target semver value. Prepend the semver value with `v`: `v1.2.3`.
+   Increment the minor version for additive changes and patch for bugfixes.
+   - For trickier changes, consider using release candidates: `rc0`, `rc1`, etc.
+2. Create an empty git commit for the tag to point at: `git commit -m 'v1.2.3-rc1' --allow-empty`.
+3. Create a new tag against that commit: `v1.2.3-rc1`.
+4. Push the changes to the library: `git push origin main v1.2.3-rc1`.
+    - You can separate these steps: `git push origin main` followed by `git push origin v1.2.3-rc1`,
+      if you want to make absolutely sure the commit you're pushing builds correctly before tagging it.
+5. Wait for the tag `build` workflow to complete.
+    - The `build` workflow should create a _draft_ release (using `softprops/action-gh-release` with `draft`
+      set to `true`) and upload built artifacts to the release.
+6. Once the workflow is complete, do whatever testing is necessary using the artifacts.
+    - TODO: We can add automation to this step so that we test on downstream deps automatically: e.g., if we
+      build a new kernel, we _should_ be able to trigger tests in the `python-sdk` _using_ that new kernel.
+7. Once we're confident the release is good, go to the releases page for the library and edit the draft release.
+    - If the release is a release candidate (`rc0..N`), make sure to mark the release as a "prerelease".
+    - Publish the draft release.
+    - This kicks off the publication workflow: taking the artifacts built during the `build` workflow and publishing
+      them to any necessary registry or repository.
+        - In extism, this publishes `extism-maturin` to PyPI as `extism-sys` and the dotnet packages to nuget.
+        - In `python-sdk`, this publishes `extism` to PyPI.
+        - In `js-sdk`, this publishes `@extism/extism` (and `extism`) to NPM.
+
+> **Note**
+> If you're at all worried about a release, use a private fork of the target library repo to test the release first (e.g., `extism/dev-extism`.)
+
+#### CLI flow
+
+For official releases:
+
+```
+$ git commit -m 'v9.9.9' --allow-empty
+$ git tag v9.9.9
+$ git push origin main v9.9.9
+$ gh run watch
+$ gh release edit v9.9.9 --tag v9.9.9 --title 'v9.9.9' --draft=false
+$ gh run watch
+```
+
+For prereleases:
+
+```
+$ git commit -m 'v9.9.9' --allow-empty
+$ git tag v9.9.9
+$ git push origin main v9.9.9
+$ gh run watch
+$ gh release edit v9.9.9 --tag v9.9.9 --title 'v9.9.9' --draft=false --prerelease
+$ gh run watch
+```
+
+### implementation
+
+Libraries should:
+
+- Provide a `ci` workflow, triggered on PR and `workflow_dispatch`.
+    - This workflow should exercise the tests, linting, and documentation generation of the library.
+- Provide a `build` workflow, triggered on `v*` tags and merges to `main`
+    - This workflow should produce artifacts and attach them to a draft release (if operating on a tag) or a `latest` release (if operating on `main`.)
+    - Artifacts include: source tarballs, checksums, shared objects, and documentation.
+- Provide a `release` workflow, triggered on github releases:
+    - This workflow should expect artifacts from the draft release to be available.
+    - Artifacts from the release should be published to their final destination as part of this workflow: tarballs to NPM, documentation to Cloudflare R2/Amazon S3/$yourFavoriteBucket.

+# extism-convert
+
+The [extism-convert](https://crates.io/crates/extism-convert) crate is used by the [Rust SDK](https://crates.io/crates/extism) and [Rust PDK](https://crates.io/crates/extism-pdk) to provide a shared interface for
+encoding and decoding values that can be passed to Extism function calls.
+
+A set of types (Json, Msgpack, Protobuf) that can be used to specify a serde encoding are also provided. These are
+similar to [axum extractors](https://docs.rs/axum/latest/axum/extract/index.html#intro) - they are
+implemented as a tuple struct with a single field that is meant to be extracted using pattern matching.
+
+## Documentation

-## Example 1
-
-This example shows how you can use the library in the most basic way. 
-It loads up the sample wasm plugin and lets you to pass inputs to it and show the ouput. 
-**Please note that on Windows you have to manually copy the `extism.dll` file to the ouput directory.**

-# Extism
-
-Extism Host SDK for Elixir and Erlang
-
-## Docs
-
-Read the [docs on hexdocs.pm](https://hexdocs.pm/extism/).
-
-## Installation
-
-You can find this package on [hex.pm](https://hex.pm/packages/extism).
-
-```elixir
-def deps do
-  [
-    {:extism, "~> 0.1.0"}
-  ]
-end
-```
-
-## Getting Started
-
-### Example
-
-```elixir
-# Create a context for which plugins can be allocated and cleaned
-ctx = Extism.Context.new()
-
-# point to some wasm code, this is the count_vowels example that ships with extism
-manifest = %{ wasm: [ %{ path: "/Users/ben/code/extism/wasm/code.wasm" } ]}
-{:ok, plugin} = Extism.Context.new_plugin(ctx, manifest, false)
-# {:ok,
-# %Extism.Plugin{
-#   resource: 0,
-#   reference: #Reference<0.520418104.1263009793.80956>
-# }}
-{:ok, output} = Extism.Plugin.call(plugin, "count_vowels", "this is a test")
-# {:ok, "{\"count\": 4}"}
-{:ok, result} = JSON.decode(output)
-# {:ok, %{"count" => 4}}
-
-# free up the context and any plugins we allocated
-Extism.Context.free(ctx)
-```
-
-### Modules
-
-The two primary modules you should learn are:
-
-* [Extism.Context](Extism.Context.html)
-* [Extism.Plugin](Extism.Plugin.html)
-
-#### Context
-
-The [Context](Extism.Context.html) can be thought of as a session. You need a context to interact with the Extism runtime. The context holds your plugins and when you free the context, it frees your plugins. It's important to free up your context and plugins when you are done with them.
-
-```elixir
-ctx = Extism.Context.new()
-# frees all the plugins 
-Extism.Context.reset(ctx)
-# frees the context and all its plugins
-Extism.Context.free(ctx)
-```
-
-#### Plugin
-
-The [Plugin](Extism.Plugin.html) represents an instance of your WASM program from the given manifest.
-The key method to know here is [Extism.Plugin#call](Extism.Plugin.html#call/3) which takes a function name to invoke and some input data, and returns the results from the plugin.
-
-```elixir
-{:ok, plugin} = Extism.Context.new_plugin(ctx, manifest, false)
-{:ok, output} = Extism.Plugin.call(plugin, "count_vowels", "this is a test")
-```
