-A shell script to make purging remote media files from a Matrix Synapse server easier.
+A shell script to make purging remote media files from a Matrix *Synapse* server 
+easier.
+
+## Dependencies
+
+These (or compatible versions) are likely included by default with your chosen 
+GNU/Linux system.
+
+- Tested with *GNU bash* 5.0.11
+- Requires *GNU date* for date/time conversion
+- Requires *Perl* for domain validation
+- Uses the `_synapse/admin/v1/purge_media_cache` API endpoint
+
+## Installation
+
+### Downloading directly
+
+Go to the [Releases](https://gitbucket.thisisjoes.site/joe/remote_media_killer/releases) 
+page and click the link for `rmk.sh` to download the script.
+
+### Downloading using *git*
+
+Navigate to a reasonable directory and download the repo with `git clone
+https://gitbucket.thisisjoes.site/git/joe/remote_media_killer.git`. This will 
+create a directory named `remote_media_killer` automatically.
+
+To ensure you run the latest version of the script, first navigate to the 
+directory with `cd remote_media_killer`, then switch to the latest version with 
+`git checkout 1.0.0`, replacing "1.0.0" with a more recent version if necessary.
+
+## Usage
+
+### Executing the script
+
+You may execute the script directly using *bash* with `bash rmk.sh`.
+
+You may also **mark the script as executable** with `chmod +x rmk.sh` and 
+execute using this shorthand `./rmk.sh`.
+
+#### Making executable from anywhere
+If you don't want to have to navigate to the directory containing the script 
+before executing it, you can make it executable from anywhere by first marking 
+it as executable (see above), then copying it to an appropriate directory 
+`cp -p rmk.sh /usr/bin/local/rmk`. Finally execute the script with `rmk`.
+
+### Inputting Information
+
+*Remote Media Killer* only takes three variables:
+
+ 1. The FQDN (Domain) of your Matrix Synapse server.
+ 2. The time/date (Time) of the oldest media you want to keep.
+ 3. The account token (Token) of a Matrix account with administrative privileges
+ on your server.
+
+Type each of these variables when prompted and press ***Enter*** to continue.
+The script will return relevant errors if there are any, as well as any output 
+from the *Synapse* server.
+
+For example, a successful media purge would result in output similar to the 
+following:
+
+```json
+{
+	"deleted": 1337
+}
+```
+
+### Common Errors
+
+If you encounter an error while using the script you may find a solution on the [Common Errors](https://gitbucket.thisisjoes.site/joe/remote_media_killer/wiki/Common Errors) page.
