+# Integrations CLI
+
+## Description
+
+This is a CLI tool for creating, validating, and maintaining OpenSearch Dashboard Integrations.
+The tool has three main functions:
+
+- `create` a new integration with a specified configuration.
+- `check` an integration for validity
+- `package` an integration to be upload to an OpenSearch Integrations instance
+
+Further information is provided in the `Usage` section.
+
+## Installation
+
+The project requires Python 3.7 or better.
+As the project is not yet a full Python package, it must be installed manually.
+To manually install, create a virtual environment and install the requirements.
+
+On Unix:
+
+```bash
+$ python3 -m venv venv
+$ source ./venv/bin/activate
+$ pip install -r requirements.txt
+```
+
+On Windows:
+
+```ps1
+> python -m venv venv
+> ./venv/Scripts/activate.ps1
+> pip install -r requirements.txt
+```
+
+On Unix, the script `integ-cli` that will automatically install necessary dependencies.
+
+```bash
+$ ./integ-cli
+```
+
+## Usage
+
+On Unix, the CLI is callable with the included `integ-cli` script.
+The simplest way to start making an integration is via `create`.
+
+```bash
+$ ./integ-cli --help
+```
+
+Further development instructions are provided below.
+
+### What's in an Integration?
+
+An integration typically consists of three components:
+
+- A Config file
+- Schemas
+- Assets
+
+The Config file `config.json` defines parameters for the integration.
+Most notably, the versions of all involved dependencies.
+It also has information like a description,
+which is used when presenting the integration in the catalog.
+
+The Schemas `/schema` are the rules for the data, and define the permitted fields and types.
+During integration creation, they are provided based on the selected components.
+These are typically not meant to be changed.
+
+The Assets `/assets` are the "heart" of the integration.
+They contain the bulk of what you develop.
+All developed Assets should be compatible with the provided components.
+Saved Objects, such as schemas and dashboards, are saved under `/assets/display`.
+
+### How to Install an Integration
+
+First, generate a template with desired defaults.
+
+```bash
+$ ./integ-cli create [NAME]
+```
+
+To begin using the integration, first load the templates in `schema`.
+The loading order generally depends on dependencies, look for a `composed_of` field.
+Dependencies are loaded by uploading them to a running OpenSearch cluster.
+For example, to load the `http` component under an `nginx` integration:
+
+```bash
+$ curl -XPUT localhost:9200/_component_template/http_template  -H "Content-Type: application/json" --data-binary "@integrations/nginx/schema/http.mapping"
+```
+
+If the component contains an `index_mapping`,
+then instead post it as an index template, e.g. with `logs`:
+
+```bash
+$ curl -XPUT localhost:9200/_index_template/logs  -H "Content-Type: application/json" --data-binary "@integrations/nginx/schema/logs.mapping"
+```
+
+Now we turn to OpenSearch Dashboards.
+First is an index pattern, which defines where to find the data.
+This should generally match the pattern `ss4o_*`.
+
+```bash
+$ curl -XPOST localhost:5601/api/saved_objects/index-pattern/sso_logs -H 'osd-xsrf: true'  -H 'Content-Type: application/json' -d '{ "attributes": { "title": "sso_logs-*-*",  "timeFieldName": "@timestamp" } }'
+```
+
+Finally, load the saved objects under `/assets/display`:
+
+```bash
+curl -XPOST "localhost:5601/api/saved_objects/_import?overwrite=true" -H "osd-xsrf: true" --form file=@integrations/nginx/assets/display/http.ndjson
+```
+
+We are aware that this is a complicated process.
+We're working on it.
+
+### How to Develop an Integration
+
+Once the saved objects have been loaded,
+you can freely change the relevant dashboards within the OpenSearch Dashboards UI.
+To update the Display Assets,
+export the new dashboards and replace the `.ndjson` files as desired.
+
+If you need to add another `schema`,
+add it to the `config.json` and add the mapping to the `/schema` directory.
+This is also going to be automated in the future.
+
+## Development
+
+Running the tests:
+
+```bash
+$ python -m unittest
+```
+
+Formatting:
+
+```bash
+$ black .
+```
