# mycorrhiza wiki
A wiki engine inspired by fungi. Not production-ready.
# 🍄 MycorrhizaWiki 0.8
A wiki engine.
Current version: 0.7 (or more?)
## Installation
```sh
git clone --recurse-submodules https://github.com/bouncepaw/mycorrhiza
cd mycorrhiza
make
# That make will:
# * run the default wiki. You can edit it right away.
# * create an executable called `mycorrhiza`. Run it with path to your wiki.
```
## Current features
* Edit pages through html forms
* Responsive design
* Works in text browsers
* Pages (called hyphae) can be in gemtext.
* Wiki pages (called hyphae) are in gemtext
* Everything is stored as simple files, no database required
* Page trees
* Changes are saved to git
* List of hyphae page
* History page
* Random page
* Light on resources: I run a home wiki on this engine 24/7 at an [Orange π Lite](http://www.orangepi.org/orangepilite/).
## Future features
* Tags
## Contributing
Help is always needed. We have a [tg chat](https://t.me/mycorrhizadev) where some development is coordinated. Feel free to open an issue or contact me.
## Future plans
* Tagging system
* Authorization
* History view
* Granular user rights
## Installation
I guess you can just clone this repo and run `make` to play around with the default wiki.
* Better history viewing
* Recent changes page
* More markups
