 # Treadl
 
-This is a monorepo containing the code for the web and mobile front-ends and web API for the Treadl platform.
-
-
-## Deploying your own version of Treadl
-
-### Run with Docker (recommended)
-
-We publish and maintain a [Docker image](https://hub.docker.com/r/wilw/treadl) for Treadl, which is the easiest way to get started.
-
-We recommend using Docker Compose and our [template `docker-compose.yml`](https://git.wilw.dev/wilw/treadl/src/branch/main/docker/docker-compose.yml) to configure the app and the MongoDB database. Download this file to your computer and then run `docker compose up` to start Treadl.
-
-In production, it is very important to change the values in the file's `environment` block to suit your own setup. We also strongly recommend the use of a reverse-proxy to handle TLS connections to the app.
-
-
-### Alternative deployment
-
-In scenarios where you want more control over the deployment, or you are more concerned with scalability, you may wish to use a more manual approach.
-
-In this case you'll need to:
-- Launch (or re-use) a MongoDB cluster/instance
-- Provision a server or service for running the Flask app (in the `api/` directory), ensuring all dependencies are installed and that it runs with the needed [environment variables](https://git.wilw.dev/wilw/treadl/src/branch/main/api/envfile.template)
-- Build the web front-end (with `npx vite build` using your needed [environment variables](https://git.wilw.dev/wilw/treadl/src/branch/main/web/.env), having installed dependencies with `npm install`) and host the resulting `dist/` directory on a server or object store.
-
-
-### S3-compatible object storage
-
-Treadl uses S3-compatible object storage for storing user uploads. If you want to allow file uploads (apart from WIF files, which are processed directly), you should create and configure a bucket for Treadl to use.
-
-Hosted options:
-
-* [Amazon S3](https://aws.amazon.com/s3)
-* [Linode Object Storage](https://www.linode.com/products/object-storage) 
-* [DigitalOcean Spaces](https://www.digitalocean.com/products/spaces)
-
-Self-hosted options:
-
-* [MinIO](https://min.io/download)
-
-Once you have a bucket, generate some access keys for the bucket that will enable Treadl to read from and write to it. Ensure you make a record of the following for inclusion in your environment file/variables:
-
-* Bucket name: The name of the S3-compatible bucket you created
-* Endpoint URL: The endpoint for your bucket. This helps Treadl understand which provider you are using.
-* Access key: The "username" or access key for your bucket
-* Secret access key: The "password" or secret access key for the bucket
-
-_Note: assets in your bucket should be public. Treadl does not currently used signed requests to access uploaded files._
-
-
-## Running Treadl locally in development mode
-
-To run Treadl locally, first ensure you have the needed software installed:
-
-- Python ^3.12
-- Node.js (we recommend v22.x)
-- Docker (we use this for the Mongo database)
-    - It can be installed via the Docker website or your package manager
-    - Ensure the Docker service is running
-- [Taskfile](https://taskfile.dev) (convenience tool for running tasks)
-    - This can be installed using `brew install go-task`
-
-To begin, clone this repository to your computer:
-
-```bash
-git clone https://git.wilw.dev/wilw/treadl.git
-```
-
-Next, initialise the project by installing dependencies and creating an environment file for the API:
-
-```bash
-task init
-```
-
-This generates a 'envfile' in your 'api' directory. You can edit this as needed (though the defaults should allow you to at least launch the app). Note: if you run this command again then any changes you made to your `envfile` will be overwritten.
-
-Finally, you can start the API and web UI by running:
-
-```bash
-task
-```
-
-Note: this command also starts the MongoDB database on port 27017. If the DB is already running, you'll see errors reported, but the API and web will still be launched.
-
-You can now navigate to [http://localhost:8002](http://localhost:8002) to start using the app.
-
-If you pull updates from the repository in the future (e.g. with `git pull`) you may need to ensure your dependencies are up-to-date before starting the app again. This can be done with:
-
-```bash
-task install-deps
-```
-
+This is a monorepo containing the code for the web front-end and web API for the Treadl web application.

-Welcome to {3}! We won't send you many emails but we just want to introduce ourselves and to give you some tips to help you get started.

-
-To login to your account please visit {1} and click Login. Use your username ({0}) and password to get back into your account.
-
-INTRODUCTION
-
-{3} has been designed as a resource for weavers – not only for those working alone as individuals, but also for groups who wish to share ideas, design inspirations and weaving patterns. It is ideal for those looking for a depository to store their individual work, and also for groups such as guilds, teaching groups, or any other collaborative working partnerships.
-Projects can be created within {3} using the integral WIF-compatible draft editor, or alternatively files can be imported from other design software along with supporting images and other information you may wish to be saved within the project file. Once complete, projects may be stored privately, shared within a closed group, or made public for other {3} users to see. The choice is yours!
-
-{3} is free to use. For more information please visit our website at {1}.
-
-GETTING STARTED
-
-Creating a profile: You can add a picture, links to a personal website, and other social media accounts to tell others more about yourself.
-
-Creating a group: You have the option to do things alone, or create a group. By clicking on the ‘Create a group’ button, you can name your group, and then invite members via email or directly through {3} if they are existing {3} users.
-
-Creating a new project: When you are ready to create/store a project on the system, you are invited to give the project a name, and a brief description. You will then be taken to a ‘Welcome to your project’ screen, where if you click on ‘add something’, you have the option of creating a new weaving pattern directly inside {3} or you can simply import a WIF file from your preferred weaving software. Once imported, you can perform further editing within {3}, or you can add supporting picture files and any other additional information you wish to keep (eg weaving notes, yarn details etc).
-
-Once complete you then have the option of saving the file privately, shared within a group, or made public for other {3} users to see.
-
-We hope you enjoy using {3} and if you have any comments or feedback please tell us by emailing {2}!
-
-Best wishes,
-
-The {3} Team

+INTRODUCTION
+
+Treadl has been designed as a resource for weavers – not only for those working alone as individuals, but also for groups who wish to share ideas, design inspirations and weaving patterns. It is ideal for those looking for a depository to store their individual work, and also for groups such as guilds, teaching groups, or any other collaborative working partnerships. 
+Projects can be created within Treadl using the integral WIF-compatible draft editor, or alternatively files can be imported from other design software along with supporting images and other information you may wish to be saved within the project file. Once complete, projects may be stored privately, shared within a closed group, or made public for other Treadl users to see. The choice is yours!
+
+Treadl is free to use. For more information please visit our website at https://treadl.com.
+
+GETTING STARTED
+
+Creating a profile: You can add a picture, links to a personal website, and other social media accounts to tell others more about yourself.
+
+Creating a group: You have the option to do things alone, or create a group. By clicking on the ‘Create a group’ button, you can name your group, and then invite members via email or directly through Treadl if they are existing Treadl users.
+
+Creating a new project: When you are ready to create/store a project on the system, you are invited to give the project a name, and a brief description. You will then be taken to a ‘Welcome to your project’ screen, where if you click on ‘add something’, you have the option of creating a new weaving pattern directly inside Treadl or you can simply import a WIF file from your preferred weaving software. Once imported, you can perform further editing within Treadl, or you can add supporting picture files and any other additional information you wish to keep (eg weaving notes, yarn details etc).
+
+Once complete you then have the option of saving the file privately, shared within a group, or made public for other Treadl users to see.
+
+We hope you enjoy using Treadl and if you have any comments or feedback please tell us by emailing hello@treadl.com!
+
+Best wishes,
+
+The Treadl Team

-# Treadl Mobile
-
-The source code for Treadl's iOS and Android application.
-
-## Overview
-
-The application is written in Dart using the Flutter framework.
-
-The mobile app currently supports only a subset of the features of the web app, and is largely useful only for the groups functionality and for adding images to projects when out and about.
-
-## Start
-
-Before building, some housekeeping needs to be done first:
-
-* The `key.properties` file needs to be created in `android/`. This should correctly reference the `key.jks` file
-* The `android/app/google-services.json` needs to be created with the Firebase configuration
-
-## Notes
-
-* Undraw hex code used: #F34E83
