-  The goal of the Nushell project is to take the Unix
-  philosophy of shells, where pipes connect simple commands
-  together, and bring it to the modern style of development.
-  Thus, rather than being either a shell, or a programming
-  language, Nushell connects both by bringing a rich
-  programming language and a full-featured shell together
-  into one package.

+## Review Process
 
 First of all, before diving into the code, if you want to create a new feature, change something significantly, and especially if the change is user-facing, it is a good practice to first get an approval from the core team before starting to work on it.
 This saves both your and our time if we realize the change needs to go another direction before spending time on it.

 ### Tests
 
-It is good practice to cover your changes with a test. Also, try to think about corner cases and various ways how your changes could break. Cover those in the tests as well.
+It is a good practice to cover your changes with a test. Also, try to think about corner cases and various ways how your changes could break. Cover those in the tests as well.
 
 Tests can be found in different places:
 * `/tests`
+* `src/tests`
 * command examples
 * crate-specific tests
 
-Most of the tests are built upon the `nu-test-support` crate. For testing specific features, such as running Nushell in a REPL mode, we have so called "testbins". For simple tests, you can find `run_test()` and `fail_test()` functions.

 ### Useful Commands
 
-As Nushell is built using a cargo workspace consisting of multiple crates keep in mind that you may need to pass additional flags compared to how you may be used to it from a single crate project.
-Read cargo's documentation for more details: https://doc.rust-lang.org/cargo/reference/workspaces.html
-
 - Build and run Nushell:
 
-  ```nushell
+  ```shell
   cargo run
   ```
 
+- Build and run with dataframe support.
+  ```shell
+  cargo run --features=dataframe
+  ```
+
 - Run Clippy on Nushell:
 
-  ```nushell
-  cargo clippy --workspace -- -D warnings -D clippy::unwrap_used
-  ```
-  or via the `toolkit.nu` command:
-  ```nushell
-  use toolkit.nu clippy
-  clippy
+  ```shell
+  cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect
   ```
 
 - Run all tests:
 
-  ```nushell
+  ```shell
   cargo test --workspace
   ```
 
-  or via the `toolkit.nu` command:
-  ```nushell
-  use toolkit.nu test
-  test
-  ```
-
 - Run all tests for a specific command
 
-  ```nushell
+  ```shell
   cargo test --package nu-cli --test main -- commands::<command_name_here>
   ```
 
 - Check to see if there are code formatting issues
 
-  ```nushell
+  ```shell
   cargo fmt --all -- --check
   ```
-  or via the `toolkit.nu` command:
-  ```nushell
-  use toolkit.nu fmt
-  fmt --check
-  ```
 
 - Format the code in the project
 
-  ```nushell
+  ```shell
   cargo fmt --all
   ```
-  or via the `toolkit.nu` command:
-  ```nushell
-  use toolkit.nu fmt
-  fmt
-  ```
-
-- Set up `git` hooks to check formatting and run `clippy` before committing and pushing:
-
-  ```nushell
-  use toolkit.nu setup-git-hooks
-  setup-git-hooks
-  ```
-  _Unfortunately, this hook isn't available on Windows._
 
 ### Debugging Tips
 
 - To view verbose logs when developing, enable the `trace` log level.
 
-  ```nushell
+  ```shell
   cargo run --release -- --log-level trace
   ```
 
 - To redirect trace logs to a file, enable the `--log-target file` switch.
-  ```nushell
+  ```shell
   cargo run --release -- --log-level trace --log-target file
   open $"($nu.temp-path)/nu-($nu.pid).log"
   ```

-## Git etiquette
-
-As nushell thrives on its broad base of volunteer contributors and maintainers with different backgrounds we have a few guidelines for how we best utilize git and GitHub for our contributions. We strive to balance three goals with those recommendations:
-
-1. The **volunteer maintainers and contributors** can easily follow the changes you propose, gauge the impact, and come to help you or make a decision.
-2. **You as a contributor** can focus most of your time on improving the quality of the nushell project and contributing your expertise to the code or documentation.
-3. Making sure we can trace back *why* decisions were made in the past.
-This includes discarded approaches. Also we want to quickly identify regressions and fix when something broke.
-
-### How we merge PRs
-
-In general the maintainers **squash** all changes of your PR into a single commit when merging.
-
-This keeps a clean enough linear history, while not forcing you to conform to a too strict style while iterating in your PR or fixing small problems. As an added benefit the commits on the `main` branch are tied to the discussion that happened in the PR through their `#1234` issue number.
-
-> **Note**
-> **Pro advice:** In some circumstances, we can agree on rebase-merging a particularly large but connected PR as a series of atomic commits onto the `main` branch to ensure we can more easily revert or bisect particular aspects.
-
-### A good PR makes a change!
-
-As a result of this PR-centric strategy and the general goal that the reviewers should easily understand your change, the **PR title and description matters** a great deal!
-
-Make sure your description is **concise** but contains all relevant information and context.
-This means demonstrating what changes, ideally through nushell code or output **examples**.
-Furthermore links to technical documentation or instructions for folks that want to play with your change make the review process much easier.
-
-> **Note**
-> Try to follow the suggestions in our PR message template to make sure we can quickly focus on the technical merits and impact on the users.
-
-#### A PR should limit itself to a single functional change or related set of same changes.
-
-Mixing different changes in the same PR will make the review process much harder. A PR might get stuck on one aspect while we would actually like to land another change. Furthermore, if we are forced to revert a change, mixing and matching different aspects makes fixing bugs or regressions much harder.
-
-Thus, please try to **separate out unrelated changes**!
-**Don't** mix unrelated refactors with a potentially contested change.
-Stylistic fixes and housekeeping can be bundled up into singular PRs.
-
-#### Guidelines for the PR title
-
-The PR title should be concise but contain everything for a contributor to know if they should help out in the review of this particular change.
-
-**DON'T**
-- `Update file/in/some/deeply/nested/path.rs`
-  - Why are you making this change?
-- `Fix 2134`
-  - What has to be fixed?
-  - Hard to follow when not online on GitHub.
-- ``Ignore `~` expansion``
-  - In what context should this change take effect?
-- `[feature] refactor the whole parser and also make nushell indentation-sensitive, upgrade to using Cpython. Let me know what you think!`
-  - Be concise
-  - Maybe break up into smaller commits or PRs if the title already appears too long?
-
-**DO**
-- Mention the nushell feature or command that is affected.
-  - ``Fix URL parsing in `http get` (issue #1234)``
-- You can mention the issue number if other context is there.
-  - In general, mention all related issues in the description to crosslink (e.g. `Fixes #1234`, `Closes #6789`)
-- For internal changes mention the area or symbols affected if it helps to clarify
-  - ``Factor out `quote_string()` from parser to reuse in `explore` ``
-
-### Review process / Merge conflicts
-
-> **Note**
-> Keep in mind that the maintainers are volunteers that need to allocate their attention to several different areas and active PRs. We will try to get back to you as soon as possible.
-
-You can help us to make the review process a smooth experience:
-- Testing:
-  - We generally review in detail after all the tests pass. Let us know if there is a problem you want to discuss to fix a test failure or forces us to accept a breaking change.
-  - If you fix a bug, it is highly recommended that you add a test that reproduces the original issue/panic in a minimal form.
-  - In general, added tests help us to understand which assumptions go into a particular addition/change.
-  - Try to also test corner cases where those assumptions might break. This can be more valuable than simply adding many similar tests.
-- Commit history inside a PR during code review:
-  - Good **atomic commits** can help follow larger changes, but we are not pedantic.
-  - We don't shame fixup commits while you try to figure out a problem. They can help others see what you tried and what didn't work. (see our [squash policy](#how-we-merge-prs))
-  - During active review constant **force pushing** just to amend changes can be confusing!
-    - GitHub's UI presents reviewers with less options to compare diffs
-    - fetched branches for experimentation become invalid!
-    - the notification a maintainer receives has a low signal-to-noise ratio
-  - Git pros *can* use their judgement to rebase/squash to clean up the history *if it aids the understanding* of a larger change during review
-- Merge conflicts:
-  - In general you should take care of resolving merge conflicts.
-    - Use your judgement whether to `git merge main` or to `git rebase main`
-    - Choose what simplifies having confidence in the conflict resolution and the review. **Merge commits in your branch are OK** in the squash model.
-  - Feel free to notify your reviewers or affected PR authors if your change might cause larger conflicts with another change.
-  - During the rollup of multiple PRs, we may choose to resolve merge conflicts and CI failures ourselves. (Allow maintainers to push to your branch to enable us to do this quickly.)

 Because most of the time you'll want to see the output of a pipeline, `table` is assumed.
 We could have also written the above:
 
 ```shell
-ls | where type == "dir"
+> ls | where type == "dir"
 ```
 
 Being able to use the same commands and compose them differently is an important philosophy in Nu.
 For example, we could use the built-in `ps` command to get a list of the running processes, using the same `where` as above.
 
 ```shell
-ps | where cpu > 0

 ## Goals
 
 Nu adheres closely to a set of goals that make up its design philosophy. As features are added, they are checked against these goals.
 
--   First and foremost, Nu is cross-platform. Commands and techniques should work across platforms and Nu has [first-class support for Windows, macOS, and Linux](devdocs/PLATFORM_SUPPORT.md).

+## Progress
+
+Nu is under heavy development and will naturally change as it matures. The chart below isn't meant to be exhaustive, but it helps give an idea for some of the areas of development and their relative maturity:
+
+| Features      | Not started | Prototype | MVP | Preview | Mature | Notes                                                                |

+| Notebook      |             |     X     |     |         |        | Initial jupyter support, but it loses state and lacks features       |
+| File ops      |             |           |     |    X    |        | cp, mv, rm, mkdir have some support, but lacking others              |
+| Environment   |             |           |     |    X    |        | Temporary environment and scoped environment variables               |

+| Plugins       |             |           |  X  |         |        | Plugins work on one row at a time, lack batching and expression eval |
+| Errors        |             |           |     |    X    |        | Error reporting works, but could use usability polish                |

-# Security Policy
-
-As a shell and programming language Nushell provides you with great powers and the potential to do dangerous things to your computer and data. Whenever there is a risk that a malicious actor can abuse a bug or a violation of documented behavior/assumptions in Nushell to harm you this is a *security* risk. 
-We want to fix those issues without exposing our users to unnecessary risk. Thus we want to explain our security policy.
-Additional issues may be part of *safety* where the behavior of Nushell as designed and implemented can cause unintended harm or a bug causes damage without the involvement of a third party.
-
-## Supported Versions
-
-As Nushell is still under very active pre-stable development, the only version the core team prioritizes for security and safety fixes is the [most recent version as published on GitHub](https://github.com/nushell/nushell/releases/latest).
-Only if you provide a strong reasoning and the necessary resources, will we consider blessing a backported fix with an official patch release for a previous version.
-
-## Reporting a Vulnerability
-
-If you suspect that a bug or behavior of Nushell can affect security or may be potentially exploitable, please report the issue to us in private. 
-Either reach out to the core team on [our Discord server](https://discord.gg/NtAbbGn) to arrange a private channel or use the [GitHub vulnerability reporting form](https://github.com/nushell/nushell/security/advisories/new).
-Please try to answer the following questions:
-- How can we reach you for further questions?
-- What is the bug? Which system of Nushell may be affected?
-- Do you have proof-of-concept for a potential exploit or have you observed an exploit in the wild?
-- What is your assessment of the severity based on what could be impacted should the bug be exploited?
-- Are additional people aware of the issue or deserve credit for identifying the issue?
-
-We will try to get back to you within a week with:
-- acknowledging the receipt of the report
-- an initial plan of how we want to address this including the primary points of contact for further communication
-- our preliminary assessment of how severe we judge the issue
-- a proposal for how we can coordinate responsible disclosure (e.g. how we ship the bugfix, if we need to coordinate with distribution maintainers, when you can release a blog post if you want to etc.)
-
-For purely *safety* related issues where the impact is severe by direct user action instead of malicious input or third parties, feel free to open a regular issue. If we deem that there may be an additional *security* risk on a *safety* issue we may continue discussions in a restricted forum.
