-# Overview 
-
-httXrp is a proof of concept for a truly serverless web architecture. If serverless simply means "a server owned by someone else", httXrp pushes that definition to its limit -or- perhaps its logical conclusion: What if that "someone else" never even intended that server to be used that way but can't do anything about it?
-
-# How it works
-
-## 1: Getting data into and out of the blockchain
-
-Transactions on the ripple blockchain are allowed to carry up to 1kB of arbitrary data via the memo field. 
-We can use this to store data of any size by building a tree of references between these transactions that can then be reassembled by reading them back from the blockchain.
-In order to generate these transactions a library called [xrpio](https://gitea.nitowa.xyz/npm-packages/xrpio.git) is used to send minimum-denomination transactions between two user controlled wallets.
-
-Highly simplified, you can visualize the process like this:
-

-
-## 2: Abstracting the webserver away from the web
-
-Using tools like `webpack`, it is possible to condense even modern complex single-page-applications into a single html file. As `xrpio` is written in JavaScript, it is even possible to embed it into such an HTML file, the use of which will become more clear a few paragraphs below.
-
-Since such a condensed HTML file is effectively nothing more than a long string it is possible to use `xrpio` to store them into the ripple blockchain and to retrieve them via a single identifying hash.
-
-<img src="https://i.imgur.com/Rwo37xJ.gif" alt="serverless web" width="650"/>
-
-## 3: Backendless dynamic web applications: Databases without databases
-
-Superficially, this technique is limited to serving static webpages, as there can be no backend communicating with these pages without betraying the serverless premise. However, since it is possible to embed `xrpio` into such a "static" page, it is possible to listen for transactions on the blockchain containing valid xrpio hashes and to dynamically update the webpage's content based on the stored data. 
-
-All necessary mechanisms can easily be embedded within that webpage, which allows us to build complex webapplications without any need for a backend server. 
-
-To prove the feasibility of this approach, this project contains a small example application in the form of a shoutbox:
-
-<img src="https://i.imgur.com/5gYLuYc.png" alt="shoutbox" width="450"/>
-
-The exact procedure is more easily explained in code than visually. The presented code snippets should be considered pseudocode, but if you're interested in the exact steps please take a look into [ShoutboxData.service.ts](https://gitea.nitowa.xyz/nitowa/httxrp/src/branch/master/src/frontend/src/app/services/ShoutboxData.service.ts). The actual implementation isn't any more complex than the steps below but they were altered for readability reasons.
-
-### Submitting a new shout to the shoutbox
-```js
-//When submitting a new shout, first the user creates a xrpio write between two of their own wallets
-submitShout = async (shout: any) => {
-    const shoutHash = await xrpio.treeWrite(shout, userWallet1.address, userWallet2.secret)
-    return await submit(shoutHash)
-}
-
-//After the shout has been written to the blockchain, 
-//the hash pointing to the data is sent to the address keeping track of the application's state
-submit = async (shoutHash: string) => {
-    return await xrpio.writeRaw({ data: shoutHash }, shoutboxAddress, userWallet1.secret)
-}
-```
-
-### Loading the application state and live updating it
-```js
-//Loading old data is as easy as parsing the historical transactions of the shoutboxAddress
-loadHistory = async () => {
-    const raw_txs = await getTransactions(shoutboxAddress)
-    //Extracts hashes from memos and reads them with xrpio
-    const shouts = await parseMemos(raw_txs.map(getMemo)) 
-    history = shouts
-}
-
-//Fetching new data as it comes in is also possible by simply subscribing to new transactions for the shoutboxAddress
-listen = async () => {
-    await subscribeTxs(async (raw_tx: any) => {
-        //Extracts hashes from memos and reads them with xrpio
-        const shout = await parseMemos(getMemo(raw_tx))
-        history.push(shout)
-    })
-}
-```

-# Credits

-- This project was originally inspired by indImm (https://ndm-inf.github.io/ndm/main), a ripple-based file storage using IPFS.
-- xrpio (https://gitea.nitowa.xyz/npm-packages/xrpio.git) is heavily used in the technical architecture of this project. It is also written and maintained by me.

+# AngularClr
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 13.3.0.
+
+## Development server
+
+Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The application will automatically reload if you change any of the source files.
+
+## Code scaffolding
+
+Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
+
+## Build
+
+Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory.
+
+## Running unit tests
+
+Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
+
+## Running end-to-end tests
+
+Run `ng e2e` to execute the end-to-end tests via a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities.
+
+## Further help
+
+To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview and Command Reference](https://angular.io/cli) page.
