+# Hello! こんにちは
+
+This is a wiki-style documentation called `doki` saved as Markdown files alongside the project
+Since they are stored in git they are versioned and all edits can be seen in the git history along with the timestamp
+and the user. They can also be perfectly synced to the current or past state of the repo or its git branch
+
+This is just a samply entry point. You can modify it and add content or add linked documents 
+to create your own wiki style documentation
+
+Press `Tab/Enter` to select and follow this [link](linked.md) to see how. 
+You can refer to external documentation by linking an [external link](https://raw.githubusercontent.com/boolean-maybe/navidown/main/README.md)
+
+ You can also create multiple entry points such as:
+- Brainstorm
+- Architecture
+- Prompts
+
+by configuring multiple plugins. Just author a file like `brainstorm.yaml`:
+
+```text
+        name: Brainstorm
+        type: doki
+        foreground: "##ffff99"
+        background: "#996600"
+        key: "F6"
+        url: new-doc-root.md
+```
+
+and place it where the `tiki` executable is. Then add it as a plugin to the tiki `config.yaml` located in the same directory:
+
+```text
+        plugins:
+            - file: brainstorm.yaml
+```

+
+`tikis` are a lightweight issue-tracking and project management tool
+check it out: https://github.com/boolean-maybe/tiki
+
+***
+
+## Features
+- [x] stored in git and always in sync
+- [x] built-in terminal UI
+- [x] AI native
+- [x] rich **Markdown** format
+
+## Git managed
+
+`tikis` (short for tickets) are just **Markdown** files in your repository
+

+## Built-in terminal UI
+
+A built-in `tiki` command displays a nice Scrum/Kanban board and a searchable Backlog view
+
+| Ready  | In progress | Waiting | Completed |
+|--------|-------------|---------|-----------|
+| Task 1 | Task 1      |         | Task 3    |
+| Task 4 | Task 5      |         |           |
+| Task 6 |             |         |           |
+
+## AI native
+
+since they are simple **Markdown** files they can also be easily manipulated via AI. For example, you can 
+use Claude Code with skills to search, create, view, update and delete `tikis`
+
+> hey Claude show me a tiki TIKI-m7n2xk
+> change it from story to a bug
+> and assign priority 1
+
+
+## Rich Markdown format
+
+Since a tiki description is in **Markdown** you can use all of its rich formatting options
+
+1. Headings
+1. Emphasis
+   - bold
+   - italic
+1. Lists
+1. Links
+1. Blockquotes
+
+You can also add a code block:
+
+```python
+def calculate_average(numbers):
+    if not numbers:
+        return 0
+    return sum(numbers) / len(numbers)
+```
+
+Happy tiking!

+# Contributing Guidelines
+
+Contributions welcome!
+
+**Before spending lots of time on something, ask for feedback on your idea first!** For general ideas or "what if" scenarios, 
+please start a thread in **GitHub Discussions**. For specific, actionable bug reports or concrete feature proposals, use **GitHub Issues**.
+
+Please search issues and pull requests before adding something new to avoid duplicating efforts and conversations.
+
+In addition to improving the project by refactoring code and implementing relevant features, this project welcomes the following types of contributions:
+
+* **Ideas**: Start a conversation in **GitHub Discussions** to brainstorm or participate in an existing **GitHub Issue** thread to help refine a technical goal.
+* **Writing**: contribute your expertise in an area by helping expand the included content.
+* **Copy editing**: fix typos, clarify language, and generally improve the quality of the content.
+* **Formatting**: help keep content easy to read with consistent formatting.
+
+## 💬 Communication Channels
+
+To keep the project organized, please use these channels:
+
+* **GitHub Discussions**: Use this for general questions, brainstorming new features, or sharing how you are using the project.
+* **GitHub Issues**: Use this strictly for bug reports or finalized feature requests that are ready for implementation.
+
+## Installing
+
+Fork and clone the repo, then `go mod download` to install all dependencies.
+
+## Testing
+
+Tests are run with `go test ./...`. Unless you're creating a failing test to increase test coverage or show a problem, please make sure all tests are passing before submitting a pull request.
+
+---
+
+# Collaborating Guidelines
+
+**This is an Open Source Project.**
+
+## Rules
+
+There are a few basic ground rules for collaborators:
+
+1. **No `--force` pushes** or modifying the Git history in any way.
+2. **Non-master branches** ought to be used for ongoing work.
+3. **External API changes and significant modifications** ought to be subject to an **internal pull request** to solicit feedback from other collaborators.
+4. Internal pull requests to solicit feedback are *encouraged* for any other non-trivial contribution but left to the discretion of the contributor.
+5. Contributors should attempt to adhere to the prevailing code style (run `go fmt` before committing).
+
+## Releases
+
+Declaring formal releases remains the prerogative of the project maintainer.

+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.

+# tiki
+
+`tiki` is a simple and lightweight way to keep your tasks, prompts, documents, ideas, scratchpads in your project **git** repo
+
+![Intro](assets/intro.png)
+
+Software development and AI assisted development in particular leaves a lot of Markdown files around - project management, 
+documentation, brainstorming ideas, incomplete implementations, AI prompts and plans and what not. 
+Stick them in your repo. Keep around for as long as you need. Find them back in **git** history. Make tasks out of them
+and take them through an agile lifecycle
+
+## Installation
+
+### Mac OS
+```bash
+# Add the tap (one-time)
+brew tap boolean-maybe/tap
+
+# Install tiki
+brew install tiki
+
+# Verify installation
+tiki --version
+```
+### Linux and Windows
+
+Download the latest distribution from the [releases page](https://github.com/boolean-maybe/tiki/releases) 
+and simply copy the `tiki` executable to any location and make it available via `PATH`
+
+## Quick start
+
+`cd` into your **git** repo and run `tiki`.
+Move your tiki around the board with `Shift ←/Shift →`.
+Make sure to press `?` for help. 
+Press `F1` to open a sample doc root. Follow links with `Tab/Enter`
+
+### AI skills
+You will be prompted to install skills for 
+- [Claude Code](https://code.claude.com)
+- [Codex](https://openai.com/codex)
+- [Opencode](https://opencode.ai)
+
+if you choose to you can mention `tiki` in your prompts to create/find/edit your tikis
+![Claude](assets/claude.png)
+
+Happy tikking! 
+
+## tiki
+Keep your tickets in your pockets!
+
+`tiki` refers to a task or a ticket (hence tiki) stored in your **git** repo
+
+- like a ticket it can have a status, priority, assignee, points, type and multiple tags attached to it
+- they are essentially just Markdown files and you can use full Markdown syntax to describe a story or a bug
+- they are stored in `.doc/tiki` subdirectory and are **git**-controlled - they are added to **git** when they are created,
+removed when they are done and the entire history is preserved in **git** repo
+- because they are in **git** they can be perfectly synced up to the state of your repo or a branch
+- you can use either the `tiki` CLI tool or any of the AI coding assistant to work with your tikis
+
+## doki
+Store your notes in remotes!
+
+`doki` refers to any file in Markdown format that is stored in the `.doc/doki` subdirectory of the **git** repo. 
+
+- like tikis they are **git**-controlled and can be maintained in perfect sync with the repo state
+- `tiki` CLI tool allows creating multiple doc roots like: Documentation, Brainstorming, Prompts etc.
+- it also allows viewing and navigation (follow links)
+
+## tiki CLI tool
+
+`tiki` CLI tool allows creating, viewing, editing and deleting tikis as well as creating custom plugins to 
+view any selection, for example, Recent tikis, Architecture docs, Saved prompts, Security review, Future Roadmap
+Read more by pressing `?` for help 
+
+## AI skills
+
+`tiki` adds optional [agent skills](https://agentskills.io/home) to the repo upon initialization
+If installed you can:
+
+- work with [Claude Code](https://code.claude.com), [Codex](https://openai.com/codex), [Opencode](https://opencode.ai) by simply mentioning `tiki` or `doki` in your prompts
+- create, find, modify and delete tikis using AI
+- create tikis/dokis directly from Markdown files
+- Refer to tikis or dokis when implementing with AI-assisted development - `implement tiki xxxxxxx`
+- Keep a history of prompts/plans by saving prompts or plans with your repo
+
+## Feedback
+
+Feedback is always welcome! Whether you have an improvement request, a feature suggestion
+or just chat:
+- use GitHub issues to submit and issue or a feature request
+- use GitHub discussions for everything else
+
+to contribute:
+[Contributing](CONTRIBUTING.md)

+
+# tiki
+
+A tiki is a Markdown file in tiki format saved in the project `.doc/tiki` directory
+with a name like `tiki-abc123.md` in all lower letters.
+IMPORTANT! files are named in lowercase always
+If this directory does not exist prompt user for creation
+
+## tiki ID format
+
+Every tiki has an ID in format:
+`TIKI-ABC123`
+where
+- `TIKI-` is a constant prefix (always uppercase)
+- `ABC123` is a 6-character random alphanumeric ID (uppercase in frontmatter, lowercase in filename)
+
+Examples:
+- ID in frontmatter: `TIKI-X7F4K2`
+- Filename: `tiki-x7f4k2.md`
+
+## tiki format
+
+A tiki format is Markdown with some requirements:
+
+### frontmatter
+
+```markdown
+---
+id: TIKI-ABC123
+title: My ticket
+type: story
+status: backlog
+priority: 3
+points: 5
+tags:
+  - markdown
+  - frontmatter
+  - metadata
+---
+```
+
+where fields can have these values:
+- type: bug, feature, task, story, epic
+- status: backlog, todo, in progress, review, done
+- priority: is any integer number from 1 to 5 where 1 is the highest priority
+- points: story points from 1 to 10
+
+### body
+
+The body of a tiki is normal Markdown
+
+if a tiki needs an attachment it is implemented as a normal markdown link to file syntax for example:
+- Logs are attached [logs](mylogs.log)
+- Here is the ![screenshot](screenshot.jpg "check out this box")
+- Check out docs: <https://www.markdownguide.org>
+- Contact: <user@example.com>
+
+## Describe
+
+When asked a question about a tiki find its file and read it then answer the question
+If the question is who created this tiki or who updated it last - use the git username
+For example:
+- who created this tiki? use `git log --follow --diff-filter=A -- <file_path>` to see who created it
+- who edited this tiki? use `git blame <file_path>` to see who edited the file
+
+## View
+
+`Created` timestamp is taken from git file creation if available else from the file creation timestamp
+`Author` is taken from git history as the git user who created the file
+
+## Creation
+
+When asked to create a tiki:
+
+- Generate a random 6-character alphanumeric ID (lowercase letters and digits)
+- The ID in frontmatter should be uppercase: `TIKI-ABC123`
+- The filename should be lowercase: `tiki-abc123.md`
+- If status is not specified use `backlog`
+- If priority is not specified use 3
+- If type is not specified - prompt the user or use `story` by default
+
+Example: for random ID `x7f4k2`:
+- Frontmatter ID: `TIKI-X7F4K2`
+- Filename: `tiki-x7f4k2.md`
+
+### Create from file
+
+if asked to create a tiki from Markdown or text file - create only a single tiki and use the entire content of the
+file as its description. Title should be a short sentence summarizing the file content
+
+#### git
+
+After a new tiki is created `git add` this file.
+IMPORTANT - only add, never commit the file without user asking and permitting
+
+## Update
+
+When asked to update a tiki - edit its file
+For example when user says "set TIKI-ABC123 in progress" find its file and edit its frontmatter line from
+`status: backlog` to `status: in progress`
+
+### git
+
+After a tiki is updated `git add` this file
+IMPORTANT - only add, never commit the file without user asking and permitting
+
+## Deletion
+
+When asked to delete a tiki `git rm` its file
+If for any reason `git rm` cannot be executed and the file is still there - delete the file
+
+## Implement
+
+When asked to implement a tiki and the user approves implementation change its status to `review` and `git add` it

+This is a wiki-style documentation called `doki` saved as Markdown files alongside the project
+Since they are stored in git they are versioned and all edits can be seen in the git history along with the timestamp
+and the user. They can also be perfectly synced to the current or past state of the repo or its git branch
+
+This is just a samply entry point. You can modify it and add content or add linked documents 
+to create your own wiki style documentation
+
+Press `Tab/Enter` to select and follow this [link](linked.md) to see how. 
+You can refer to external documentation by linking an [external link](https://raw.githubusercontent.com/boolean-maybe/navidown/main/README.md)
+
+ You can also create multiple entry points such as:
+- Brainstorm
+- Architecture
+- Prompts
+
+by configuring multiple plugins. Just author a file like `brainstorm.yaml`:
+
+```text
+        name: Brainstorm
+        type: doki
+        foreground: "##ffff99"
+        background: "#996600"
+        key: "F6"
+        url: new-doc-root.md
+```
+
+and place it where the `tiki` executable is. Then add it as a plugin to the tiki `config.yaml` located in the same directory:

+# Hello! こんにちは
+
+`tikis` are a lightweight issue-tracking and project management tool
+check it out: https://github.com/boolean-maybe/tiki
+
+***
+
+## Features
+- [x] stored in git and always in sync
+- [x] built-in terminal UI
+- [x] AI native
+- [x] rich **Markdown** format
+
+## Git managed
+
+`tikis` (short for tickets) are just **Markdown** files in your repository
+
+🌳 /projects/my-app
+├─ 📁 .doc
+│  └─ 📁 tiki
+│     ├─ 📝 tiki-k3x9m2.md
+│     ├─ 📝 tiki-7wq4na.md
+│     ├─ 📝 tiki-p8j1fz.md

+└─ 📄 LICENSE
+
+## Built-in terminal UI
+
+A built-in `tiki` command displays a nice Scrum/Kanban board and a searchable Backlog view
+
+| Ready  | In progress | Waiting | Completed |
+|--------|-------------|---------|-----------|
+| Task 1 | Task 1      |         | Task 3    |
+| Task 4 | Task 5      |         |           |
+| Task 6 |             |         |           |
+
+## AI native
+
+since they are simple **Markdown** files they can also be easily manipulated via AI. For example, you can 
+use Claude Code with skills to search, create, view, update and delete `tikis`
+
+> hey Claude show me a tiki TIKI-m7n2xk
+> change it from story to a bug
+> and assign priority 1
+
+
+## Rich Markdown format
+
+Since a tiki description is in **Markdown** you can use all of its rich formatting options
+
+1. Headings
+1. Emphasis
+   - bold
+   - italic
+1. Lists
+1. Links
+1. Blockquotes
+
+You can also add a code block:
+
+```python
+def calculate_average(numbers):
+    if not numbers:
+        return 0
+    return sum(numbers) / len(numbers)
+```
+
+Happy tiking!
