-# SurfSmart
\ No newline at end of file
+# SurfSmart
+
+SurfSmart is a web application with a Flask backend and a React/Vite frontend.
+
+## Deployment Overview
+
+1. **System packages**
+   ```bash
+   sudo dnf install -y git python3.12 python3.12-virtualenv nodejs npm redis
+   ```
+
+2. **Clone the repository**
+   ```bash
+   git clone <repo-url> /opt/surfsmart
+   cd /opt/surfsmart
+   ```
+
+   Remove any bundled virtual environment if present:
+   ```bash
+   rm -rf backend_flask/flask
+   ```
+
+3. **Create a Python virtual environment and install dependencies**
+   ```bash
+   python3.12 -m venv venv
+   source venv/bin/activate
+   pip install --upgrade pip
+   pip install -r backend_flask/requirements.txt
+   ```
+
+4. **Environment variables**
+   Create a `.env` file and define at least the following:
+   ```bash
+   MONGO_URI="mongodb+srv://<user>:<pass>@cluster.mongodb.net/?retryWrites=true&w=majority"
+   SECRET_KEY="replace_with_random_secret"
+   FRONTEND_ORIGIN="https://surfsmart.tech"
+   FLASK_CONFIG="production"
+   CELERY_BROKER_URL="redis://localhost:6379/0"
+   CELERY_RESULT_BACKEND="redis://localhost:6379/0"
+   ```
+
+5. **Systemd services**
+   See `surfsmart-backend.service` and `surfsmart-celery.service` examples in the repository root for running Gunicorn and Celery as services.
+
+6. **Build the React frontend**
+   ```bash
+   cd frontend_react
+   npm install
+   npm run build
+   ```
+   The build artifacts will be located in `frontend_react/dist`.
+
+7. **Nginx configuration**
+   Configure Nginx to serve the static frontend and proxy `/api/` requests to Gunicorn running the Flask application.
+
+This is only a brief outline. Adjust file paths and domain names to your environment.

-<#
-.Synopsis
-Activate a Python virtual environment for the current PowerShell session.
-
-.Description
-Pushes the python executable for a virtual environment to the front of the
-$Env:PATH environment variable and sets the prompt to signify that you are
-in a Python virtual environment. Makes use of the command line switches as
-well as the `pyvenv.cfg` file values present in the virtual environment.
-
-.Parameter VenvDir
-Path to the directory that contains the virtual environment to activate. The
-default value for this is the parent of the directory that the Activate.ps1
-script is located within.
-
-.Parameter Prompt
-The prompt prefix to display when this virtual environment is activated. By
-default, this prompt is the name of the virtual environment folder (VenvDir)
-surrounded by parentheses and followed by a single space (ie. '(.venv) ').
-
-.Example
-Activate.ps1
-Activates the Python virtual environment that contains the Activate.ps1 script.
-
-.Example
-Activate.ps1 -Verbose
-Activates the Python virtual environment that contains the Activate.ps1 script,
-and shows extra information about the activation as it executes.
-
-.Example
-Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
-Activates the Python virtual environment located in the specified location.
-
-.Example
-Activate.ps1 -Prompt "MyPython"
-Activates the Python virtual environment that contains the Activate.ps1 script,
-and prefixes the current prompt with the specified string (surrounded in
-parentheses) while the virtual environment is active.
-
-.Notes
-On Windows, it may be required to enable this Activate.ps1 script by setting the
-execution policy for the user. You can do this by issuing the following PowerShell
-command:
-
-PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
-
-For more information on Execution Policies: 
-https://go.microsoft.com/fwlink/?LinkID=135170

-.Description
-Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the
-given folder, and returns them in a map.
-
-For each line in the pyvenv.cfg file, if that line can be parsed into exactly
-two strings separated by `=` (with any amount of whitespace surrounding the =)
-then it is considered a `key = value` line. The left hand string is the key,
-the right hand is the value.
-
-If the value starts with a `'` or a `"` then the first and last character is
-stripped from the value before being captured.
-
-.Parameter ConfigDir
-Path to the directory that contains the `pyvenv.cfg` file.
