To create a tar.gz archive from a given folder you can use the following command. This will compress the contents of source-folder-name to a tar.gz
archive named tar-archive-name.tar.gz
<pre class="language-bash"><code class="language-bash">tar -zcvf tar-archive-name.tar.gz source-folder-name
</code></pre>
To extract a tar.gz compressed archive you can use the following command
tar -zxvf tar-archive-name.tar.gz
<pre><code>
If its a gzipped file

```bash
gzip -d tar-archive-name.tar.gz
</code></pre>
This will extract the archive to the folder tar-archive-name.
To Preserve permissions
<pre class="language-bash"><code class="language-bash">tar -pcvzf tar-archive-name.tar.gz source-folder-name
</code></pre>
Switch the ‘c’ flag to an ‘x’ to extract (uncompress).
<pre class="language-bash"><code class="language-bash">tar -pxvzf tar-archive-name.tar.gz
</code></pre>

Welcome the the COMMONS Lab Open Dendron !

In the [COMMONS Lab](https://www.unifr.ch/bio/en/groups/allard/) we intent to follow the [Open Notebook Science](https://en.wikipedia.org/wiki/Open-notebook_science) approach to document our research.

For this we use the [Dendron](https://www.dendron.so/) system as a mean to efficiently capture notes and publish them.

## What is this note

This note is a succinct tutorial note aiming to get you started in the use of the COMMONS Lab Dendron.

## Tutorial

### Dendron. 

#### What is Dendron ?

> Dendron is an open-source, local-first, markdown-based, note-taking tool. Think of it as a cache for everything that you care about - if you've spent more then five minutes solving a problem, you should never spent any more time solving the same exact problem.
> 
> Dendron is a knowledge base built by and for developers and integrates natively with IDEs like VS Code and VSCodium.

#### Where to get more info on Dendron ?

- You can get more information in the Dendron system at the official website www.dendron.so
- All the Dendron documentation is hosted here https://wiki.dendron.so/. It is, obviously, a Dendron itself.

#### Concrete steps to access and contribute to the DBGI Dendron

1. Install [VSCode](https://code.visualstudio.com/download)
2. Install [Dendron](https://marketplace.visualstudio.com/items?itemName=dendron.dendron) from the VSCode marketplace 
3. Clone the COMMONS Dendron repo

    In your terminal
    ```
    git clone https://github.com/commons-research/commons-dws-public.git
    ```
4. In VSCode open (File/Open) the cloned repository.
5. Voila ! You should now be in the COMMONS Lab Open Dendron.

Feel free to explore and contribute.
A first, important step could be to configure VSCode so that you can easily add a daily note. See steps described at [[open-notebook.commons.setup]]
