-# Polus CSV Collection Merger Plugin
-
-This plugin helps to merge multiple CSV Collections in WIPP into one collection for later analysis.
-
-For more information on WIPP, visit the [official WIPP page](https://isg.nist.gov/deepzoomweb/software/wipp).
-
-**This plugin is in development and is subject for change**
-
-## Options
-
-This plugin takes four input parameters and one output parameter:
-
-| Name                 | Description                                    | I/O    | WIPP Type     |
-|----------------------|------------------------------------------------|--------|---------------|
-| `input-collection-a` | Input CSV collection A                         | Input  | csvCollection |
-| `input-collection-b` | Input CSV collection B                         | Input  | csvCollection |
-| `append-a`           | Option to append collection ID to files from A | Input  | boolean       |
-| `append-b`           | Option to append collection ID to files from B | Input  | boolean       |
-| `output`             | Output CSV collection                          | Output | csvCollection |
-
-## Build the plugin
-
-```bash
-docker build . -t labshare/polus-csv-collection-merger:0.1.1
-```
-
-
-## Run the plugin
-
-### Manually
-
-To test, create 3 folders: `<COLLECTION A>` and `<COLLECTION B>` should contain csv collections you would like to merge. `<COLLECTION C>` is the target folder which will contain the merged files.
-
-Run the docker container 
-```bash
-docker run -v <COLLECTION A>:/a \
-           -v <COLLECTION B>:/b \
-           -v <COLLECTION C>:/c \
-           labshare/polus-csv-collection-merger:0.1.1 \
-           --input-collection-a /a \
-           --input-collection-b /b \
-           --append-a 'true' \
-           --append-b 'true' \
-           --output /c
-```
