 # LNURLp
+
+## Create a static QR code people can use to pay over Lightning Network
+
+LNURL is a range of lightning-network standards that allow us to use lightning-network differently. An LNURL-pay is a link that wallets use to fetch an invoice from a server on-demand. The link or QR code is fixed, but each time it is read by a compatible wallet a new invoice is issued by the service and sent to the wallet.
+
+[**Wallets supporting LNURL**](https://github.com/fiatjaf/awesome-lnurl#wallets)
+
+## Usage
+
+1. Create an LNURLp (New Pay link)\
+   ![create lnurlp](https://i.imgur.com/rhUBJFy.jpg)
+
+   - select your wallets
+   - make a small description
+   - enter amount
+   - if _Fixed amount_ is unchecked you'll have the option to configure a Max and Min amount
+   - you can set the currency to something different than sats. For example if you choose EUR, the satoshi amount will be calculated when a user scans the LNURLp
+   - You can ask the user to send a comment that will be sent along with the payment (for example a comment to a blog post)
+   - Webhook URL allows to call an URL when the LNURLp is paid
+   - Success mesage, will send a message back to the user after a successful payment, for example a thank you note
+   - Success URL, will send back a clickable link to the user. Access to some hidden content, or a download link
+
+2. Use the shareable link or view the LNURLp you just created\
+   ![LNURLp](https://i.imgur.com/C8s1P0Q.jpg)
+   - you can now open your LNURLp and copy the LNURL, get the shareable link or print it\

 # Offline Shop
+
+## Create QR codes for each product and display them on your store for receiving payments Offline
+
+[![video tutorial offline shop](http://img.youtube.com/vi/_XAvM_LNsoo/0.jpg)](https://youtu.be/_XAvM_LNsoo 'video tutorial offline shop')
+
+LNBits Offline Shop allows for merchants to receive Bitcoin payments while offline and without any electronic device.
+
+Merchant will create items and associate a QR code ([a LNURLp](https://github.com/lnbits/lnbits/blob/master/lnbits/extensions/lnurlp/README.md)) with a price. He can then print the QR codes and display them on their shop. When a costumer chooses an item, scans the QR code, gets the description and price. After payment, the costumer gets a confirmation code that the merchant can validate to be sure the payment was successful.
+
+Costumers must use an LNURL pay capable wallet.
+
+[**Wallets supporting LNURL**](https://github.com/fiatjaf/awesome-lnurl#wallets)
+
+## Usage
+
+1. Entering the Offline shop extension you'll see an Items list, the Shop wallet and a Wordslist\
+   ![offline shop back office](https://i.imgur.com/Ei7cxj9.png)
+2. Begin by creating an item, click "ADD NEW ITEM"
+   - set the item name and a small description
+   - you can set an optional, preferably square image, that will show up on the costumer wallet - _depending on wallet_
+   - set the item price, if you choose a fiat currency the bitcoin conversion will happen at the time costumer scans to pay\
+     ![add new item](https://i.imgur.com/pkZqRgj.png)
+3. After creating some products, click on "PRINT QR CODES"\
+   ![print qr codes](https://i.imgur.com/2GAiSTe.png)
+4. You'll see a QR code for each product in your LNBits Offline Shop with a title and price ready for printing\
+   ![qr codes sheet](https://i.imgur.com/faEqOcd.png)
+5. Place the printed QR codes on your shop, or at the fair stall, or have them as a menu style laminated sheet
+6. Choose what type of confirmation do you want costumers to report to merchant after a successful payment\
+   ![wordlist](https://i.imgur.com/9aM6NUL.png)
+
+   - Wordlist is the default option: after a successful payment the costumer will receive a word from this list, **sequentially**. Starting in _albatross_ as costumers pay for the items they will get the next word in the list until _zebra_, then it starts at the top again. The list can be changed, for example if you think A-Z is a big list to track, you can use _apple_, _banana_, _coconut_\
+     ![totp authenticator](https://i.imgur.com/MrJXFxz.png)
+   - TOTP (time-based one time password) can be used instead. If you use Google Authenticator just scan the presented QR with the app and after a successful payment the user will get the password that you can check with GA\
+     ![disable confirmations](https://i.imgur.com/2OFs4yi.png)
+   - Nothing, disables the need for confirmation of payment, click the "DISABLE CONFIRMATION CODES"

-![lnurl](https://i.imgur.com/qHi7ExL.png)
+LNURL is a range of lightning-network standards that allow us to use lightning-network differently. An LNURL withdraw is the permission for someone to pull a certain amount of funds from a lightning wallet.
 
+The most common use case for an LNURL withdraw is a faucet, although it is a very powerful technology, with much further reaching implications. For example, an LNURL withdraw could be minted to pay for a subscription service. Or you can have a LNURLw as an offline Lightning wallet (a pre paid "card"), you use to pay for something without having to even reach your smartphone.

+[**Wallets supporting LNURL**](https://github.com/fiatjaf/awesome-lnurl#wallets)
+
+## Usage
+
+#### Quick Vouchers
+
+LNBits Quick Vouchers allows you to easily create a batch of LNURLw's QR codes that you can print and distribute as rewards, onboarding people into Lightning Network, gifts, etc...
+
+1. Create Quick Vouchers\
+   ![quick vouchers](https://i.imgur.com/IUfwdQz.jpg)
+   - select wallet
+   - set the amount each voucher will allow someone to withdraw
+   - set the amount of vouchers you want to create - _have in mind you need to have a balance on the wallet that supports the amount \* number of vouchers_
+2. You can now print, share, display your LNURLw links or QR codes\
+   ![lnurlw created](https://i.imgur.com/X00twiX.jpg)
+   - on details you can print the vouchers\
+     ![printable vouchers](https://i.imgur.com/2xLHbob.jpg)
+   - every printed LNURLw QR code is unique, it can only be used once
+
+#### Advanced
+
+1. Create the Advanced LNURLw\
+   ![create advanced lnurlw](https://i.imgur.com/OR0f885.jpg)
+   - set the wallet
+   - set a title for the LNURLw (it will show up in users wallet)
+   - define the minimum and maximum a user can withdraw, if you want a fixed amount set them both to an equal value
+   - set how many times can the LNURLw be scanned, if it's a one time use or it can be scanned 100 times
+   - LNBits has the "_Time between withdraws_" setting, you can define how long the LNURLw will be unavailable between scans
+   - you can set the time in _seconds, minutes or hours_
+   - the "_Use unique withdraw QR..._" reduces the chance of your LNURL withdraw being exploited and depleted by one person, by generating a new QR code every time it's scanned
+2. Print, share or display your LNURLw link or it's QR code\
+   ![lnurlw created](https://i.imgur.com/X00twiX.jpg)
+
+**LNBits bonus:** If a user doesn't have a Lightning Network wallet and scans the LNURLw QR code with their smartphone camera, or a QR scanner app, they can follow the link provided to claim their satoshis and get an instant LNBits wallet!

 # DJ Livestream
 
-An extension to help DJs to conduct music livestreams.
+## Help DJ's and music producers conduct music livestreams
 
-It produces a single static QR code that can be shown on screen. Once someone scans that QR code with an lnurl-pay capable wallet they will see the name of the track being played at that time and the name of the producer.
+LNBits Livestream extension produces a static QR code that can be shown on screen while livestreaming a DJ set for example. If someone listening to the livestream likes a song and want to support the DJ and/or the producer he can scan the QR code with a LNURL-pay capable wallet.
 
-They will then be given the opportunity to send a tip and a message related to that specific track and if they pay an amount over a specific threshold they will be given a link to download it (optional).
+When scanned, the QR code sends up information about the song playing at the moment (name and the producer of that song). Also, if the user likes the song and would like to support the producer, he can send a tip and a message for that specific track. If the user sends an amount over a specific threshold they will be given a link to download it (optional).
 
 The revenue will be sent to a wallet created specifically for that producer, with optional revenue splitting between the DJ and the producer.
 
+[**Wallets supporting LNURL**](https://github.com/fiatjaf/awesome-lnurl#wallets)
+
+[![video tutorial livestream](http://img.youtube.com/vi/zDrSWShKz7k/0.jpg)](https://youtu.be/zDrSWShKz7k 'video tutorial offline shop')
+
+## Usage
+
+1. Start by adding a track\
+   ![add new track](https://i.imgur.com/Cu0eGrW.jpg) - set the producer, or choose an existing one - set the track name - define a minimum price where a user can download the track - set the download URL, where user will be redirected if he tips the livestream and the tip is equal or above the set price\
+   ![track settings](https://i.imgur.com/HTJYwcW.jpg)
+2. Adjust the percentage of the pay you want to take from the user's tips. 10%, the default, means that the DJ will keep 10% of all the tips sent by users. The other 90% will go to an auto generated producer wallet\
+   ![adjust percentage](https://i.imgur.com/9weHKAB.jpg)
+3. For every different producer added, when adding tracks, a wallet is generated for them\
+   ![producer wallet](https://i.imgur.com/YFIZ7Tm.jpg)
+4. On the bottom of the LNBits DJ Livestream extension you'll find the static QR code ([LNURL-pay](https://github.com/lnbits/lnbits/blob/master/lnbits/extensions/lnurlp/README.md)) you can add to the livestream or if you're a street performer you can print it and have it displayed
+5. After all tracks and producers are added, you can start "playing" songs\
+   ![play tracks](https://i.imgur.com/7ytiBkq.jpg)
+6. You'll see the current track playing and a green icon indicating active track also\
+   ![active track](https://i.imgur.com/W1vBz54.jpg)
+7. When a user scans the QR code, and sends a tip, you'll receive 10%, in the example case, in your wallet and the producer's wallet will get the rest. For example someone tips 100 sats, you'll get 10 sats and the producer will get 90 sats
+   - producer's wallet receiving 18 sats from 20 sats tips\
+     ![producer wallet](https://i.imgur.com/OM9LawA.jpg)
+
+## Use cases
+
+You can print the QR code and display it on a live gig, a street performance, etc... OR you can use the QR as an overlay in an online stream of you playing music, doing a DJ set, making a podcast.
+
+You can use the extension's API to trigger updates for the current track, update fees, add tracks...

-Try to include an image
-<img src="https://i.imgur.com/9i4xcQB.png">
+## Hide content behind a paywall, a user has to pay some amount to access your hidden content
 
+A Paywall is a way of restricting to content via a purchase or paid subscription. For example to read a determined blog post, or to continue reading further, to access a downloads area, etc...
 
-<h2>If your extension has API endpoints, include useful ones here</h2>
+## Usage
 
-<code>curl -H "Content-type: application/json" -X POST https://YOUR-LNBITS/YOUR-EXTENSION/api/v1/EXAMPLE -d '{"amount":"100","memo":"example"}' -H "X-Api-Key: YOUR_WALLET-ADMIN/INVOICE-KEY"</code>
+1. Create a paywall by clicking "NEW PAYWALL"\
+   ![create new paywall](https://i.imgur.com/q0ZIekC.png)
+2. Fill the options for your PAYWALL
+   - select the wallet
+   - set the link that will be unlocked after a successful payment
+   - give your paywall a _Title_
+   - an optional small description
+   - and set an amount a user must pay to access the hidden content. Note this is the minimum amount, a user can over pay if they wish
+   - if _Remember payments_ is checked, a returning paying user won't have to pay again for the same content.\
+     ![paywall config](https://i.imgur.com/CBW48F6.png)
+3. You can then use your paywall link to secure your awesome content\
+   ![paywall link](https://i.imgur.com/hDQmCDf.png)
+4. When a user wants to access your hidden content, he can use the minimum amount or increase and click the "_Check icon_" to generate an invoice, user will then be redirected to the content page\
