+# E-Fish tracking
+
+Tool for easier handling of tracking results.
+
+## Installation
+
+### 1. Clone git repository
+
+```shell
+git clone https://whale.am28.uni-tuebingen.de/git/jgrewe/efish_tracking.git
+```
+
+### 2. Change into directory
+
+```shell
+cd efish_tracking
+````
+
+### 3. Install with pip
+
+```shell
+pip3 install -e . --user
+```
+
+The ```-e``` installs the package in an *editable* model that you do not need to reinstall whenever you pull upstream changes.
+
+If  you leave away the ```--user``` the package will be installed system-wide.
+
+## TrackingResults
+
+Is a class that wraps around the *.h5 files written by DeepLabCut
+
+## ImageMarker
+
+Class that allows for creating MarkerTasks to get specific positions in a video.
