-Convert quickscope into a quotation.

+Convert quickscope into a quotation.
+
+## Build
+
+```sh
+docker build -t quickscope .
+```
+
+Run with:
+
+```sh
+docker run \
+  -e PROJECT_ACCESS_TOKEN="<your-gitlab-access-token>"
+  -e CI_PROJECT_URL="https://git.radicallyopensecurity.com/<your-namespace>/<your-project>" \
+  -e CI_PROJECT_ID="<your-gitlab-project-id>" \
+  -e CI_SERVER_URL="https://git.radicallyopensecurity.com/" \
+  --name convert \
+  --rm \
+  convert
+```
+
+## Development
+
+Create an `.env` file:
+
+```sh
+PROJECT_ACCESS_TOKEN="<your-gitlab-access-token>"
+COOKIE="_eyed_p_session=<your-eyedp-session-id>;"
+```
+
+```sh
+docker run \
+  --env-file ./.env
+  -e CI_PROJECT_URL="https://git.radicallyopensecurity.com/<your-namespace>/<your-project>" \
+  -e CI_PROJECT_ID="<your-gitlab-project-id>" \
+  -e CI_SERVER_URL="https://git.radicallyopensecurity.com/" \
+  --name convert \
+  --rm \
+  convert
+```
+
+## Test
+
+Make sure submodules are loaded and up to date:
+
+```sh
+git submodule update --init
+git submodule update
+```
+
+Make sure image is built:
+
+```sh
+docker build -t quickscope .
+```
+
+```sh
+./integration.sh
+```
+
+This will:
+
+- Create a copy of the `PenText` submodule which contains a sample quickscope report.
+- Perform the conversion
+- Compare the diff after conversion, with the currently committed diff
+- Report differences
+
+It will output:
+
+- ./integration/new.diff => The diff after conversion
+- ./integration/integration.diff => Diff between new diff and currently committed diff
