+## General
+
+Vim wiki is a vim plugin making it possible to effectivly keep wiki-style knowledge sorted on your local machine.
+The single pages are written in markdown and are interlinked.
+It can further be used as a Diary or to manage TODO lists, and to export the whole wiki in to an website, meaning single HTML files, which are interlinked and can be published.
+Since every entry is a simple markdown file, this makes it easy to collaborate on a common wiki using git.
+
+### Installation
+
+The vim-wiki plugin can be installed like every vim plugin.
+To test if the install was successful, execute `:VimwikiIndex` in the command prompt of vim.
+You have to add the following lines to your `.vimrc`, irrespective of the installation method used.
+```vim
+set nocompatible
+filetype plugin on
+syntax on
+```
+
+#### [Vim-Plug](https://github.com/junegunn/vim-plug)
+
+Add `Plug 'vimwiki/vimwiki'` to the Plug-Section of your `init.vim` or `.vimrc`.
+Afterwords run `:PlugInstall` in the command prompt of vim.
+
+#### [Pathogen](https://www.vim.org/scripts/script.php?script_id=2332)
+
+Go to your vim config folder and clone the vimwiki github repository into the `bundle` folder.
+```sh
+cd $CONFIG/vim
+mkdir bundle
+cd bundle
+git clone https://github.com/vimwiki/vimwiki.git
+```
+Afterwords run `:Helptags` in the command prompt of vim.
+
+#### [Vundle](https://github.com/VundleVim/Vundle.vim)
+
+Add `Plugin 'vimwiki/vimwiki'` to the `init.vim` or `.vimrc`.
+Afterwords run `vim +PluginInstall +qall` in the shell to install it.
+
+### Configuration
+
+To go to the index page you enter `<leader>ww`.
+For a bare vim-install this is `\ww`.
+To change this, put the following line to your `.vimrc`:
+```vim
+map <leader>v :VimwikiIndex <Enter>
+```
+On default the directory for the markdown files is `~/vimwiki/index.wiki`.
+To change this, add the following line to your `.vimrc`:
+```vim
+	let g:vimwiki_list = [{'path': '/PATH/TO/DIRECTORY/vimwiki', 'syntax': 'markdown', 'ext': '.md'}]
+```
+Here you can also add several wikis.
+Assuming you want to have one wiki exclusively for coding related matters and an other one for every day related knowledge, add
+```vim
+let g:vimwiki_list = [
+	\ {'path': '/PATH/wiki_code', 'syntax': 'markdown', 'ext': '.md'},
+	\ {'path': '/PATH/wiki_household', 'syntax': 'markdown', 'ext': '.md'} ]
+```
+to your `.vimrc`.
+To then select the correct wiki to go to, use `<leader>ws` to select which wiki you want to choose.
+You can also use `[number] <leader>ww` to directly move to the corresponding wiki.
+
+All the key bindings and how to remap them are listed under `:h vimwiki-mappings`.
+
+### Basic Usage
+
+#### Navigation
+
+To navigate the vimwiki you need to know 3 basic commands.
+
+1. Add a new page
+	- To add a new page, you write the name of the main wiki-index page. Visually select the title of the page and press `<Enter>`. This creates a link to a new markdown file.
+2. Go to a new page
+	- To follow a link, press `<Enter>` on the link again, this opens the new markdown file.
+3. Go one page back
+	- To go back to the previous page, press `<Backspace>`.
+
+#### Diary
+
+To keep a diary in your vimwiki, use the `:VimwikiMakeDiaryNote` command. This opens a markdown file with the current date as its name.
+Write your entry and save it.
+To link the new entry to the diary index page, use `:VimwikiDiaryIndex` to go to the index page itself.
+Then execute `:VimwikiDiaryGenerateLinks`. This adds all unlinked diary entries to the diary index page.
+The default keybindings for this are
+- `[number] <leader> wi`: Move to the diary index of wiki i.
+- `[number] <leader> w <leader> w`: Open todays diary file for wiki i.
+- `[number] <leader> w <leader> t`: Open todays diary file for wiki i in a new tab.
+
+#### Encryption of pages
+
+Using the [vim gnupg](https://github.com/jamessan/vim-gnupg) plugin, you can encrypt your pages.
+This is done by first adding the folling line to your `.vimrc`.
+```vim
+let g:GPGFilePattern = '*.\(gpg\|asc\|pgp\)\(.md\)\='
+```
+To then create an encrypted entry, you have to add `.asc` to your link.
+The new file will then be named `filename.asc.md`.
+Opening it initially, a prompt will ask you which key to choose.
+Select thee correct key and close the prompt.
+
+#### Conversion to HTML
+
+Vimwiki has the built in feature to export your wiki in to an HTML wiki.
+The build in version only supports the vimwiki markup language.
+If you write in this language, you should change the `vimwiki_list` command such that it includes `'syntax': 'vimwiki', 'ext': '.wiki'`.
+Afterwords you can just run
+```
+:VimwikiAll2HTML
+```
+To only convert the current page to html, use `:Vimwiki2HTML`.
+which converts all existing `.wiki` files in to html files and links them against each other.
+
+To expand this capability to markdown, you have to include certain wrapper scripts.
