+# Export Saved Reddit Posts
+
+Exports saved and/or upvoted Reddit posts into a HTML file that is ready to be imported into Google Chrome. Sorts items into folders by subreddit.
+
+## Requirements

+* [pip](https://pip.pypa.io/en/stable/installing/)

+
+## Installation
+
+First, make sure you have [Python 3.x](https://www.python.org/downloads/), [pip](https://pip.pypa.io/en/stable/installing/), and [git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git) installed on your machine.
+
+Run the following in your command prompt to install:
+
+    git clone https://github.com/csu/export-saved-reddit.git
+    cd export-saved-reddit
+    pip install -r requirements.txt
+
+To install without git, [download the source code from GitHub](https://github.com/csu/export-saved-reddit/archive/master.zip), extract the archive, and follow the steps above beginning from the second line.
+
+## Usage
+1. [Make a new Reddit](https://www.reddit.com/prefs/apps) app to get a `client id` and a `client secret`.
+
+    - Scroll to the bottom of the page and click "create app"
+    - You can name the app anything (e.g. "export-saved"). Select the "script" option. Put anything for the redirect URI (e.g. https://christopher.su).
+    - After creating the app, the client id will appear under the app name while the client secret will be labeled "secret".
+
+2. In the `export-saved-reddit` folder, rename the `AccountDetails.py.example` file to `AccountDetails.py`.
+3. Open the `AccountDetails.py` in a text editor and enter your Reddit username, password, client id, client secret within the corresponding quotation marks. Save and close the file.
+4. Back in your shell, run `python export_saved.py` in the `export-saved-reddit` folder. This will run the export, which will create `chrome-bookmarks.html` and `export-saved.csv` files containing your data in the same folder.
