-## Quickstart
 
+## Prerequisites
+
+- Python >3.6
+- Pip
+
+## Quickstart (using poetry)
+
+```
+pip3 install poetry
+git clone <repo-url>
+cd <local-repo-path>
+local-repo-path $ git submodule init && git submodule update
+local-repo-path $ poetry install
+local-repo-path $ poetry run python webdavcli/webdavcli.py -h
+Using python3.7 (3.7.6)
+usage: webdavcli.py [-h] remote_dir local_dir
+
+Pulls a WebDAV remote directory.
+
+positional arguments:
+  remote_dir  remote source path
+  local_dir   local target path
+
+optional arguments:
+  -h, --help  show this help message and exit
+
+```
+
+To use the client, create a file `.env` in the `local-repo-path` with the following content (adapt it according to your environment):
+
+```
+WEBDAV_SYNC_REMOTE_URL="https://nextcloud.example.tld/remote.php/dav/files/<username>/"
+WEBDAV_SYNC_REMOTE_USER="<username>"
+WEBDAV_SYNC_REMOTE_PASS="<password>"
+```
+
+Ensure that the remote WebDAV directory exists and then run the client, supplying a remote directory and a local target directory:
+
+```
+poetry run python webdavcli/webdavcli.py <remote_dir> <local_dir>
+```
