+Small script to get next prayer time
+
+## Prerequesites
+
+A linux machine, that's it lol. The only special commands being used are `date`,  `wget` or `curl`, `grep`, `cut`
+
+## Usage
+
+- Download the script
+
+```sh
+wget -O prayertime.sh https://git.shihaam.dev/flamexode/prayertimes-sh/raw/branch/master/prayertime.sh
+# or
+curl -o prayertime.sh https://git.shihaam.dev/flamexode/prayertimes-sh/raw/branch/master/prayertime.sh
+```
+
+- Just run the script, make sure that `prayertimes.csv` isn't a file being used
+
+```sh
+chmod +x prayertime.sh
+./prayertime.sh
+# or specify your own file
+./prayertime.sh -f "/home/flamexode/projects/prayertimes-db/out/102.csv"
+```
+
+
+> Note: You'll need to use the [island mappings](https://github.com/WovenCoast/prayertimes-db/blob/main/island-mapping.md) to find the island ID for your island. 
+> Island ID for Male' is 102, this is selected by default if no input is given
+
+- (optional)  Add a cronjob to store the output for other programs
+
+```cron
+* * * * * /home/flamexode/scripts/prayertime.sh > /home/flamexode/.prayertime
+```
+
+> Note: Make sure you use your own username
+
+Now you can use ~/.prayertime to quickly read the next prayer time
