 ## Naming Languages
 
-Languages should be named after their interpreters, and the command line binaries you call.
+Languages should be named after their interpreters, and the command line binaries you call. The language version should use semantic versioning.
 For example, the full name of the standard python interpreter is `CPython`, however we would name it `python`, after the main binary which it provides.
 In the example of NodeJS, we would call this `node`, after the main binary.

 Piston takes additional steps to make it resistant to
 various privilege escalation, denial-of-service, and resource saturation threats. These steps include:
 
-- Disabling outgoing network interaction
-- Capping max processes at 256 by default (resists `:(){ :|: &}:;`, `while True: os.fork()`, etc.)
-- Capping max files at 2048 (resists various file based attacks)
-- Cleaning up all temp space after each execution (resists out of drive space attacks)
-- Running as a variety of unprivileged users
-- Capping runtime execution at 3 seconds
-- Capping stdout to 65536 characters (resists yes/no bombs and runaway output)

Subject: [PATCH 48/72] api(job): Switch process cleanup to sync The system
 used to use async. This would result in execution is handed off to other
 processes. In the case of a forkbomb was used, it could circumvent the
 janitor as it consumed more CPU time which would prevent the process janitor
 from reading the process information in.

Subject: [PATCH 66/72] BREAKING: replace custom build scripts with nix

General:
- Switched to yarn to better work with nix-based tooling
- Switched package system to use nix. This stops double dependencies and slow cloud compile times, while providing more compile/runtime support to the Nix project
- Removed container builder in favor of internal container tooling
- Package versions no-longer need to be SemVer compliant
- Removed "piston package spec" files, replaced with nix-flake based runtimes
- Exported nosocket and piston-api as packages within the nix-flake
- Removed repo container
- Switched docker building to nix-based container outputting
- Removed docker compose as this is a single container
- Removed package commands from CLI

Packages:
- Move bash, clojure, cobol, node, python2, python3 to new format
- Remainder of packages still need to be moved

v2 API:
- Removed "version" specifier. To select specific versions, use the v3 api
- Removed "/package" endpoints as this doesn't work with the new nix-based system

v3 API:
- Duplicate of v2 API, except instead of passing in a language name an ID is used intead.

-# Contributing packages to the Piston Repository
-
-## Naming Languages
-
-Languages should be named after their interpreters, and the command line binaries you call. The language version should use semantic versioning.
-For example, the full name of the standard python interpreter is `CPython`, however we would name it `python`, after the main binary which it provides.
-In the example of NodeJS, we would call this `node`, after the main binary.
-
-## Creating new languages
-
-See [deno/1.7.5/](deno/1.7.5/) or any other directory for examples.
-
-1. Create a new branch on your fork of engineer-man/piston
-
-2. Create directories named `[language]/[version]`. See Naming Languages for how to determine the name for your language
-
-3. Create a file named `build.sh`, adding a shebang for bash `#!/bin/bash` on the first line.
-In this file put any steps to compile the specified langauge.
-This script should download sources, compile sources and output binaries. They should be dumped into the current working directory, removing any files which aren't required in the process.
-
-4. Create a file named `run`, containing bash script to run the interpreter.
-The first argument given to this script (`$1`) is the name of the main file, with the remaining ones as program arguments.
-STDIN is piped directly into the run file, and as such nothing special is required to deal with STDIN, except leaving it open.
-
-5. Create a file named `compile`, containing bash script to compile sources into binaries. This is only required if the language requires a compling stage.
-The first argument is always the main file, followed the names of the other files as additional arguements. If the language does not require a compile stage, don't create a compile file.
-
-6. Create a file named `environment`, containing `export` statements which edit the environment variables accordingly. The `$PWD` variable should be used, and is set inside the package directory when running on the target system.
-
-7. Create a test script starting with test, with the file extension of the language. This script should simply output the phrase `OK`. For example, for mono we would create `test.cs` with the content:
-```cs
-using System;
-
-public class Test
-{
-    public static void Main(string[] args)
-    {
-        Console.WriteLine("OK");
-    }
-}
-```
-
-8. Create a `metadata.json` file which contains metadata about the language and interpreter. This simply contains the language name, as in the folder name, the version as in the folder name, aliases that can be used to call this package, limit overrides (if any) that can be used to override the default constraints and finally a dependencies map.
-The dependencies map contains the keys as language names, and the values as semver selectors for packages.
-```json
-{
-    "language": "deno",
-    "version": "1.7.5",
-    "dependencies": {},
-    "aliases": ["deno-ts", "deno-js"]
-}
-```
-If the interpreter/compiler provides multiple languages, then the provides property should be used:
-```json
-{
-    "language": "dotnet",
-    "version": "5.0.201",
-    "provides": [
-        {
-            "language": "basic.net",
-            "aliases": [
-                "basic",
-                "visual-basic",
-                "visual-basic.net",
-                "vb",
-                "vb.net",
-                "vb-dotnet",
-                "dotnet-vb",
-                "basic-dotnet",
-                "dotnet-basic"
-            ],
-            "limit_overrides": { "max_process_count": 128 }
-        },
-        {
-            "language": "fsi",

-9. Test your package builds with running `make [language]-[version].pkg.tar.gz`.
-If it all goes to plan, you should have a file named `[language]-[version].pkg.tar.gz`, in this case you're good to go, albeit it is preferable to test the package locally as follows
-```shell
-./piston build-pkg [package] [version]
-./piston ppman install [package]=[version]
-./piston run [package] -l [version] packages/[package]/[version]/test.*
-```
-
-10. Commit your changes, using message format of `pkg([language]-[version]): Added [language] [version]`
-Any additional commits regarding this package should start with `pkg([language]-[version]): `
-
-11. Create a pull request (currently to v3 branch), referencing an Issue number (if there is one associated).
