-## Moving from GitHub to Gitea
-
-**TL;DR: Please go to my Gitea instance instead of GitHub for anything related to imgupload. [https://git.bbaovanc.com/bbaovanc/imgupload](https://git.bbaovanc.com/bbaovanc/imgupload)**
-
-This repository might not exist on GitHub in the future! Releases will not be released here in the future. Instead, they will be released on the repository on my Gitea instance, which you can find [here](https://git.bbaovanc.com/bbaovanc/imgupload). Issues and pull requests should also be created on Gitea. For now, commits will still be pushed to this repository, but that may change in the future.

-## What is imgupload?
-
 imgupload is a Flask + uWSGI application to serve as an all-purpose image/file uploader over POST requests.
 
----
+### Installation
-
+1. Clone the repository: `git clone https://github.com/BBaoVanC/imgupload.git`
-## FAQ
+2. Enter the imgupload directory: `cd imgupload`
-
+3. Create a virtualenv: `python3 -m venv env`
-**Where can I send bug reports and feature requests?**
+4. Enter the virtualenv: `source env/bin/activate`
-
+5. Install dependencies: `python3 -m pip install -r requirements.txt`
-You can create an issue [here](https://git.bbaovanc.com/bbaovanc/imgupload/issues).
+6. Run the Flask app
-
-**How do I use this program?**
-
-See [Installation](#installation)
-
-**I want to make a pull request. Where should I do that?**
-
-First, fork [this repository](https://git.bbaovanc.com/bbaovanc/imgupload). If you don't have an account on my Gitea site yet, you can either create one, or sign in using your GitHub account. Commit your changes to your fork, and then create a pull request.

-## Installation
 
+## Running the Flask app
 ### Using uWSGI
+[https://uwsgi-docs.readthedocs.io/en/latest/Configuration.html](https://uwsgi-docs.readthedocs.io/en/latest/Configuration.html)
 
-Note: replace `www-data` with whatever user your webserver runs as.
+Instructions specific to imgupload are coming soon
-
-1. Go to /srv: `cd /srv`
-2. Clone the repository: `git clone https://git.bbaovanc.com/bbaovanc/imgupload.git`
-3. Change ownership of /srv/imgupload: `sudo chown www-data:www-data /srv/imgupload`
-4. Enter www-data user: `sudo su www-data`
-5. Change directories to /srv/imgupload: `cd /srv/imgupload`
-6. Checkout the version you want (replace [version] with desired version tag: `git checkout [version]`
-7. Enter the imgupload directory: `cd imgupload`
-8. Create a virtualenv: `python3 -m venv env`
-9. Enter the virtualenv: `source env/bin/activate`
-10. Install dependencies: `python3 -m pip install -r requirements.txt`
-11. Leave the www-data user: `exit`
-12. Copy the default uWSGI configuration: `sudo cp /srv/imgupload/uwsgi.ini.default /etc/uwsgi/apps-available/imgupload.ini`
-13. Modify `/etc/uwsgi/apps-available/imgupload.ini` to your preferences
-14. Enable imgupload: `sudo ln -s /etc/uwsgi/apps-available/imgupload.ini /etc/uwsgi/apps-enabled/`
-15. Restart uWSGI: `sudo systemctl restart uwsgi`
-16. Set up your webserver to proxy the uwsgi.sock
-
-Example NGINX location block:
-
-```nginx
-location /upload {
-    include uwsgi_params;
-    uwsgi_pass unix:/srv/imgupload/uwsgi.sock;
-    client_max_body_size 25M;
-}
-```
 
 ### Using Flask development server
-
-#### Setup
-
 ```shell
-git clone https://git.bbaovanc.com/bbaovanc/imgupload.git
+$ source env/bin/activate  # if you haven't already entered the virtualenv
-cd imgupload
+$ export FLASK_APP=imgupload.py
-python3 -m venv env
+$ flask run
-source env/bin/activate
-pip3 install -r requirements.txt
 ```
-
-#### Run
-
-```shell
-export FLASK_APP=imgupload.py
-flask run
-```
