+#### Installing AppImages ⚡️
+All AppImages from the [AppImage Catalog](https://appimage.github.io) and [AppImage catalog v2](https://g.srevinsaju.me/get-appimage) can be installed using zap with their registered name.
+
+```bash
+zap install element
+```
+will ask you the version of element you would like to install + download them and do all the hard work of integrating into your system, 
+i.e creating desktop files, etc.
+
+You can also install appimages from GitHub releases
+
+```bash
+zap install --github --from vscodium/vscodium
+```
+
+will put some options which will let you choose the best version for your system.
+
+It is also possible to install AppImage from URLs
+
+```bash
+zap install --from https://f.sed.lol/wow.AppImage
+```
+
+#### Updating AppImages 🔄
+AppImages can be optionally, [automatically updated using the `zapd`](#Daemon), but to achieve this manually, you need to 
+```bash
+zap update firefox
+```
+This will make use of the update information embedded within the appimage, which if exists, will be used to 'delta-update' the latest
+version, by downloading "only" the parts which have changed.
+
+For those AppImages not supporting delta updates, you can still do 
+```bash
+zap install zoom
+```
+to install the latest version of Zoom.
+
+
+##### Upgrade 🚀
+`zap` also supports updating all the apps together using `appimage-update`. 
+
+```bash
+zap upgrade
+```
+
+
+#### Configuration ⚙️
+It is possible to interactively configure `zap`. All you need to do is 
+```bash
+zap init
+```
+And answer all the questions that would follow.
+
+
+#### Daemon 🏃
+
+`zapd` is a Zap AppImage daemon which periodically checks for updates.
+
+```bash
+zap daemon --install
+```
+
+This will install a `systemd` service in the local (user) level, which will spawn `zap daemon` which auto-updates 
+the AppImages. 
+
+To run the daemon (sync), do 
+```bash
+zap daemon
+```
+
