+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+open an issue on GitHub .
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

+
+## Adding a new `step`
+
+In `topgrade`'s term, package manager is called `step`.
+To add a new `step` to `topgrade`:
+
+1. Add a new variant to
+   [`enum Step`](https://github.com/topgrade-rs/topgrade/blob/cb7adc8ced8a77addf2cb051d18bba9f202ab866/src/config.rs#L100)
+
+   ```rust
+   pub enum Step {
+       // Existed steps
+       // ...
+
+       // Your new step here!
+       // You may want it to be sorted alphabetically because that looks great:)
+       Xxx,
+   }
+   ```
+
+2. Implement the update function
+
+   You need to find the appropriate location where this update function goes, it should be
+   a file under [`src/steps`](https://github.com/topgrade-rs/topgrade/tree/master/src/steps),
+   the file names are self-explanatory, for example, `step`s related to `zsh` are
+   placed in [`steps/zsh.rs`](https://github.com/topgrade-rs/topgrade/blob/master/src/steps/zsh.rs).
+
+   Then you implement the update function, and put it in the file where it belongs.
+
+   ```rust
+   pub fn run_xxx(ctx: &ExecutionContext) -> Result<()> {
+       // Check if this step is installed, if not, then this update will be skipped.
+       let xxx = require("xxx")?;
+
+       // Print the separator
+       print_separator("xxx");
+
+       // Invoke the new step to get things updated!
+       ctx.run_type()
+          .execute("xxx")
+          .arg(/* args required by this step */)
+          .status_checked()
+   }
+   ```
+
+   Such a update function would be conventionally named `run_xxx()`, where `xxx`
+   is the name of the new step, and it should take a argument of type
+   `&ExecutionContext`, this is adequate for most cases unless some extra stuff is
+   needed (You can find some examples where extra arguments are needed
+   [here](https://github.com/topgrade-rs/topgrade/blob/7e48c5dedcfd5d0124bb9f39079a03e27ed23886/src/main.rs#L201-L219)).
+
+   Update function would usually do 3 things:
+   1. Check if the step is installed
+   2. Output the Separator
+   3. Invoke the step
+
+   Still, this is sufficient for most tools, but you may need some extra stuff
+   with complicated `step`.
+
+3. Finally, invoke that update function in `main.rs`
+
+   ```rust
+   runner.execute(Step::Xxx, "xxx", || ItsModule::run_xxx(&ctx))?;
+   ```
+
+   We use [conditional compilation](https://doc.rust-lang.org/reference/conditional-compilation.html)
+   to separate the steps, for example, for steps that are Linux-only, it goes
+   like this:
+
+   ```
+   #[cfg(target_os = "linux")]
+   {
+       // Xxx is Linux-only
+       runner.execute(Step::Xxx, "xxx", || ItsModule::run_xxx(&ctx))?;
+   }
+   ```
+
+   Congrats, you just added a new `step`:)

+## Before you submit your PR
+
+Make sure your patch passes the following tests on your host:
+
+```shell
+$ cargo build
+$ cargo fmt
+$ cargo clippy
+$ cargo test
+```
+
+Don't worry about other platforms, we have most of them covered in our CI.
+
+## Some tips
+
+1. Locale
+
+   Some `step` respects locale, which means their output can be in language other
+   than English, we should not do check on it.
+
+   For example, one may want to check if a tool works by doing this:
+
+   ```rust
+   let output = Command::new("xxx").arg("--help").output().unwrap();
+   let stdout = from_utf8(output.stdout).expect("Assume it is UTF-8 encoded");
+
+   if stdout.contains("help") {
+       // xxx works
+   }
+   ```
+
+   If `xxx` respects locale, then the above code should work on English system,
+   on a system that does not use English, e.g., it uses Chinese, that `"help"` may be
+   translated to `"帮助"`, and the above code won't work.

-## Fork
-This is a fork of [topgrade by r-darwish](https://github.com/r-darwish/topgrade) to keep it maintained.
 
+## Introduction
+
+> **Note**
+> This is a fork of [topgrade by r-darwish](https://github.com/r-darwish/topgrade) to keep it maintained.
 
 Keeping your system up to date usually involves invoking multiple package managers.
 This results in big, non-portable shell one-liners saved in your shell.
-To remedy this, _topgrade_ detects which tools you use and runs the appropriate commands to update them.
+To remedy this, **Topgrade** detects which tools you use and runs the appropriate commands to update them.
 
 ## Installation

+Other systems users can either use `cargo install` or the compiled binaries from the release page.
 The compiled binaries contain a self-upgrading feature.
 
-Topgrade requires Rust 1.51 or above.
-
-## Documentation[WIP]
-You can visit the documentation at [topgrade-rs.github.io](https://topgrade-rs.github.io/) .
+> Currently, Topgrade requires Rust 1.65 or above. In general, Topgrade tracks 
+> the latest stable toolchain.
 
 ## Usage
-Just run `topgrade`.
-See [the wiki](https://github.com/r-darwish/topgrade/wiki/Step-list) for the list of things Topgrade supports.
 
-## Customization
+Just run `topgrade`.
+
+## Configuration 
+
 See `config.example.toml` for an example configuration file.
 
-### Configuration path
+## Migration and Breaking Changes
 
-The configuration should be placed in the following paths depending by the operating system:
+Whenever there is a **breaking change**, the major version number will be bumped,
+and we will document these changes in the release note, please take a look at 
+it when updated to a major release.
 
-* **Windows** - `%APPDATA%/topgrade.toml`
-* **macOS** and **other Unix systems** - `${XDG_CONFIG_HOME:-~/.config}/topgrade.toml`
+> Got a question? Feel free to open an issue or discussion!
 
-## Contribution
-### Problems or missing features?
-Open a new Issue describing your problem and if possible with a possible solution.
-### Missing a feature or found an unsupported tool/distro?
-Just let us now what you are missing by opening an issue.
-For tools please open an Issue describing the tool, which platforms it supports and if possible, give us an example of its usage.
-### Want to contribute to the code?
-Just fork the repository and start coding.
+### Configuration Path
+
+#### `CONFIG_DIR` on each platform
+- **Windows**: `%APPDATA%`
+- **macOS** and **other Unix systems**: `${XDG_CONFIG_HOME:-~/.config}`
+
+`topgrade` will look for the configuration file in the following places, in order of priority:
+
+1. `CONFIG_DIR/topgrade.toml`
+2. `CONFIG_DIR/topgrade/topgrade.toml`
+
+If the file with higher priority is present, no matter it is valid or not, the other configuration files will be ignored.
+
+On the first run(no configuration file exists), `topgrade` will create a configuration file at `CONFIG_DIR/topgrade.toml` for you.
+
+### Custom Commands
+
+Custom commands can be defined in the config file which can be run before, during, or after the inbuilt commands, as required.
+By default, the custom commands are run using a new shell according to the `$SHELL` environment variable on unix (falls back to `sh`) or `pwsh` on windows (falls back to `powershell`).
+
+On unix, if you want to run your command using an interactive shell, for example to source your shell's rc files, you can add `-i` at the start of your custom command.
+But note that this requires the command to exit the shell correctly or else the shell will hang indefinitely.
+
+## Remote Execution
 
-## Remote execution
 You can specify a key called `remote_topgrades` in the configuration file.
-This key should contain a list of hostnames that have topgrade installed on them.
+This key should contain a list of hostnames that have Topgrade installed on them.
 Topgrade will use `ssh` to run `topgrade` on remote hosts before acting locally.
 To limit the execution only to specific hosts use the `--remote-host-limit` parameter.

+## Roadmap
+
+- [ ] Add a proper testing framework to the code base.
+- [ ] Add unit tests for package managers.
+- [ ] Split up code into more maintainable parts, eg. putting every linux package manager in a own submodule of linux.rs.

RELEASE_PROCEDURE.md

+> This document lists the steps that lead to a successful release of Topgrade.
+
+1. Open a PR that:
+   
+   > Here is an [Example PR](https://github.com/topgrade-rs/topgrade/pull/652) 
+   > that you can refer to.
+
+   1. bumps the version number.
+
+      > If there are breaking changes, the major version number should be increased.
+
+   2. Overwrite [`BREAKINGCHANGES`][breaking_changes] with 
+      [`BREAKINGCHANGES_dev`][breaking_changes_dev], and create a new dev file:
+
+      ```sh'
+      $ cd topgrade
+      $ cp BREAKINGCHANGES_dev.md BREAKINGCHANGES.md
+      $ touch BREAKINGCHANGES_dev.md
+      ```
+
+      [breaking_changes_dev]: https://github.com/topgrade-rs/topgrade/blob/main/BREAKINGCHANGES_dev.md
+      [breaking_changes]: https://github.com/topgrade-rs/topgrade/blob/main/BREAKINGCHANGES.md
+
+2. Check and merge that PR.
+
+3. Go to the [release](https://github.com/topgrade-rs/topgrade/releases) page 
+   and click the [Draft a new release button](https://github.com/topgrade-rs/topgrade/releases/new)
+
+4. Write the release notes
+
+   We usually use GitHub's [Automatically generated release notes][auto_gen_release_notes]
+   functionality to generate release notes, but you write your own one instead.
+
+   [auto_gen_release_notes]: https://docs.github.com/en/repositories/releasing-projects-on-github/automatically-generated-release-notes
+
+5. Attaching binaries
+
+   You don't need to do this as our CI will automatically do it for you, 
+   binaries for Linux, macOS and Windows will be created and attached.
+
+   And the CI will publish the new binary to:
+
+   1. AUR
+   2. PyPi
+   3. Homebrew (seems that this is not working correctly)
+   4. Winget
+
+6. Manually release it to Crates.io
+   
+   > Yeah, this is unfortunate, our CI won't do this for us. We should probably add one.
+
+   1. `cd` to the Topgrade directory, make sure that it is the latest version 
+      (i.e., including the PR that bumps the version number).
+   2. Set up your token with `cargo login`.
+   3. Dry-run the publish `cargo publish --dry-run`.
+   4. If step 3 works, then do the final release `cargo publish`.
+
+   > You can also take a look at the official tutorial [Publishing on crates.io][doc]
+   >
