+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+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.

+
+Thank you for your interest in contributing to `topgrade`! 
+We welcome and encourage contributions of all kinds, such as:
+
+1. Issue reports or feature requests
+2. Documentation improvements
+3. Code (PR or PR Review)
+
+Please follow the [Karma Runner guidelines](http://karma-runner.github.io/6.2/dev/git-commit-msg.html)
+for commit messages.
+
+## 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`:)
+
+## Modification to the configuration entries
+
+If your PR has the configuration options 
+(in [`src/config.rs`](https://github.com/topgrade-rs/topgrade/blob/master/src/config.rs)) 
+modified:
+
+1. Adding new options
+2. Changing the existing options
+
+Be sure to apply your changes to
+[`config.example.toml`](https://github.com/topgrade-rs/topgrade/blob/master/config.example.toml),
+and have some basic documentations guiding user how to use these options.
+
+## Breaking changes
+
+If your PR introduces a breaking change, document it in `BREAKINGCHANGE_dev.md`,
+it should be written in Markdown and wrapped in 80, for example:
+
+```md
+1. The configuration location has been updated to x.
+
+2. The step x has been removed.
+
+3. ...
+```
+
+## 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.

 ## Installation
 
-- Arch Linux: [AUR](https://aur.archlinux.org/packages/topgrade) package.
-- NixOS: _topgrade_ package in `nixpkgs`.
-- macOS: [Homebrew](https://formulae.brew.sh/formula/topgrade) or [MacPorts](https://ports.macports.org/port/topgrade/).
+[![Packaging status](https://repology.org/badge/vertical-allrepos/topgrade.svg)](https://repology.org/project/topgrade/versions)
 
-Other systems users can either use `cargo install` or use the compiled binaries from the release page.
+- Arch Linux: [AUR](https://aur.archlinux.org/packages/topgrade)
+- NixOS: [Nixpkgs](https://search.nixos.org/packages?show=topgrade)
+- Void Linux: [XBPS](https://voidlinux.org/packages/?arch=x86_64&q=topgrade)

+
+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
-
-> **Warning**
-> Work in Progress
-
-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 documentation](https://topgrade-rs.github.io/) for the list of things Topgrade supports.
 
-## Customization
+## 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** - `${XDG_CONFIG_HOME:-~/.config}/topgrade.toml`
+> Got a question? Feel free to open an issue or discussion!
+
+### Configuration Path
+
+#### `CONFIG_DIR` on each platform
+- **Windows**: `%APPDATA%`
+- **macOS** and **other Unix systems**: `${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
+
+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.
+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.
