     <string name="help_node"><![CDATA[
-        <h1>Nodes</h1>
+        <h1>Nodos</h1>
         <h2>TL;DR</h2>
-        <p>Refresh the nodes list by pulling down &amp; bookmark 3&#8211;5 nodes to allow Monerujo
-        to choose the best one for you!</p>
-        <h2>What&apos;s a Node?</h2>
-        <p>Monerujo uses a Remote Node (sometimes also called Daemon) to communicate with
-        the Monero Network without having to download and store a copy of the
-        whole blockchain itself.<p>
-        <h2>Node List</h2>
-        <p>If the list is empty, you can either add new nodes manually or let Monerujo
-        scan the network for you. Or both. Read on&#8230;</p>
-        <p>The node list shows all currently known nodes. Additionally, the timestamp
-        of the latest block known to each node is shown under the node name. An icon
-        representing the node&apos;s response behaviour
-        (which indicates the level of connectivity to be expected)
-        is shown next to each node.</p>
-        <p>Any node in the list can be bookmarked for later use.
-        Nodes which are not bookmarked will be forgotten.<p>
-        <p>Monerujo will choose the optimal bookmarked node each time you use it.
-        It does this by checking the blockheight (how up-to-date
-        is the node?) as well as the response behaviour (how fast does the node respond to requests?).</p>
-        <p>The list is sorted by these characteristics, so the top node would be the one Monerujo
-        would choose right now. The bottom of the list would show very slow or unavailable nodes.</p>
-        <h2>Add a Node</h2>
-        <p>By touching the &quot;Add Node&quot; button at the bottom, you will be asked to
-        enter the node details in the following dialog.
-        The &quot;Address&quot; is the hostname or IP-address of the node - this is the only
-        mandatory entry.
-        Enter the &quot;Port&quot; if the node runs on a non-default port (e.g. 18089).
-        You can also optionally name the node, so you can identify it easier later on.
-        Some nodes require credentials to use them. Enter the provided username &amp;
-        password in the appropriate fields. Now you can &quot;Test&quot; these setting.
-        The &quot;Test Results&quot; will display the blockheight, response time and actual IP used.
-        The result may also be an error - usually because the hostname provided is
-        not reachable in a sensible amount of time or the credentials are incorrect.
-        Or the hostname/port combination does not point to an actual Monero Node!
-        Once the test passes (no error) - you&apos;re set to press &quot;OK&quot; to save &amp;
-        bookmark this node.</p>
-        <h2>Scan for Nodes</h2>
-        <p>Additionally, you can scan the network for nodes. Monerujo will start
-        scanning the network for Remote Nodes on port 18089. It begins by asking your
-        bookmarked nodes for other peers in the Monero P2P network and then continues
-        by asking those for their peers, and so on. If you have no bookmarked nodes
-        (or they don&apos;t tell us about their peers),
-        Monerujo will go straight to the Monero seed nodes hardcoded into Monero. The
-        scan stops when it finds 10 remote nodes in total.</p>
+        <p>Refresca la lista de nodos al mostrar los marcadores de nodos para permitir a Monerujo
+        elegir el mejor para ti.</p>
+        <h2>¿Qué es un Nodo?h2>
+        <p>Monerujo usa un Nodo Remoto (algunas veces también llamado Daemon) para comunicarse con
+        la red de Monero sin tener que descargar y almacenar una copia de la
+        cadena de bloques completa.<p>
+        <h2>Lista de Nodos</h2>
+        <p>Si la lista está vacía, puedes agregar nuevos nodos manualmente o dejar que Monerujo
+        escanee la red por ti. O ambos.</p>
+        <p>La lista de nodos muestra todos los nodos actualmente conocidos. Adicionalmente, la marca de tiempo
+        del último bloque conocido para cada nodo se muestra bajo el nombre del nodo. Un icono
+        representando el comportamiento de respuesta del nodo
+        (el cual indica el nivel de conectividad esperado)
+        es mostrado seguido de cada nodo.</p>
+        <p>Cualquier nodo en la lista puede ser marcado para un posterior uso.
+        Nodos que no sean marcados serán olvidados.<p>
+        <p>Monerujo elegirá el nodo marcado óptimo cada vez que lo uses.
+        Esto lo hace revisando la altura del bloque (¿qué tan al día
+        está el nodo?) así como el comportamiento de respuesta (¿qué tan rápido responde el nodo a solicitudes?).</p>
+        <p>La lista se ordena por estas características, por lo tanto el primer nodo en la lista sería el que Monerujo
+        elegiría en ese momento. El final de la lista mostraría nodos muy lentos o no disponibles.</p>
+        <h2>Agregar un Nodo</h2>
+        <p>Presionando en el botón &quot;Agregar Nodo&quot; en la parte inferior, se te pedirá que
+        ingreses los detalles del nodo en el siguiente cuadro de diálogo.
+        La &quot;Dirección&quot; es el nombre del host o dirección IP del nodo - esta es la única
+        entrada obligatoria.
+        Ingresa el &quot;Puerto&quot; si el nodo se ejecuta en un puerto que no es por defecto (e.g. 18089).
+        Puedes también nombrar el nodo opcionalmente, para que puedas identificarlo después fácilmente.
+        Algunos nodos requieren credenciales para usarlos. Ingresa el nombre de usuario provisto &amp;
+        contraseña en los campos apropiados. Ahora puedes &quot;Verificar&quot; estos ajustes.
+        Los &quot;Resultados de la Prueba&quot; mostrarán la altura del bloque, tiempo de respuesta y dirección IP real usados.
+        El resultado puede ser también un error - usualmente porque el nombre de host provisto no
+        es alcanzable en una sensible cantidad de tiempo o las credenciales son incorrectas.
+        O la combinación nombre de host/puerto no indican a un nodo de Monero real.
+        Una vez que la prueba sea exitosa (sin error) - estás listo para presionar &quot;OK&quot; para guardar &amp;
+        como marcador este nodo.</p>
+        <h2>Escanear por Nodos</h2>
+        <p>Adicionalmente, puedes escanear la red por nodos. Monerujo empezará
+        escaneando la red por Nodos Remotos con puerto 18089. Comienza preguntando tus
+        nodos marcados por otros compañeros en la red P2P de Monero y después continúa
+        preguntando por nodos a ellos por sus compañeros, y así. Si no tienes nodos marcados
+        (o no nos comunican sobre sus compañeros),
+        Monerujo irá directo a los nodos semilla de Monero codificados en Monero. El
+        escaneo parará cuando encuentre 10 nodos remotos en total.</p>

     <string name="help_node"><![CDATA[
-        <h1>Nodes</h1>
+        <h1>Nós</h1>
         <h2>TL;DR</h2>
-        <p>Refresh the nodes list by pulling down &amp; bookmark 3&#8211;5 nodes to allow Monerujo
-        to choose the best one for you!</p>
-        <h2>What&apos;s a Node?</h2>
-        <p>Monerujo uses a Remote Node (sometimes also called Daemon) to communicate with
-        the Monero Network without having to download and store a copy of the
-        whole blockchain itself.<p>
-        <h2>Node List</h2>
-        <p>If the list is empty, you can either add new nodes manually or let Monerujo
-        scan the network for you. Or both. Read on&#8230;</p>
-        <p>The node list shows all currently known nodes. Additionally, the timestamp
-        of the latest block known to each node is shown under the node name. An icon
-        representing the node&apos;s response behaviour
-        (which indicates the level of connectivity to be expected)
-        is shown next to each node.</p>
-        <p>Any node in the list can be bookmarked for later use.
-        Nodes which are not bookmarked will be forgotten.<p>
-        <p>Monerujo will choose the optimal bookmarked node each time you use it.
-        It does this by checking the blockheight (how up-to-date
-        is the node?) as well as the response behaviour (how fast does the node respond to requests?).</p>
-        <p>The list is sorted by these characteristics, so the top node would be the one Monerujo
-        would choose right now. The bottom of the list would show very slow or unavailable nodes.</p>
-        <h2>Add a Node</h2>
-        <p>By touching the &quot;Add Node&quot; button at the bottom, you will be asked to
-        enter the node details in the following dialog.
-        The &quot;Address&quot; is the hostname or IP-address of the node - this is the only
-        mandatory entry.
-        Enter the &quot;Port&quot; if the node runs on a non-default port (e.g. 18089).
-        You can also optionally name the node, so you can identify it easier later on.
-        Some nodes require credentials to use them. Enter the provided username &amp;
-        password in the appropriate fields. Now you can &quot;Test&quot; these setting.
-        The &quot;Test Results&quot; will display the blockheight, response time and actual IP used.
-        The result may also be an error - usually because the hostname provided is
-        not reachable in a sensible amount of time or the credentials are incorrect.
-        Or the hostname/port combination does not point to an actual Monero Node!
-        Once the test passes (no error) - you&apos;re set to press &quot;OK&quot; to save &amp;
-        bookmark this node.</p>
-        <h2>Scan for Nodes</h2>
-        <p>Additionally, you can scan the network for nodes. Monerujo will start
-        scanning the network for Remote Nodes on port 18089. It begins by asking your
-        bookmarked nodes for other peers in the Monero P2P network and then continues
-        by asking those for their peers, and so on. If you have no bookmarked nodes
-        (or they don&apos;t tell us about their peers),
-        Monerujo will go straight to the Monero seed nodes hardcoded into Monero. The
-        scan stops when it finds 10 remote nodes in total.</p>
+        <p>Atualize a lista de nós puxando para baixo &amp; favorite 3&#8211;5 nós para permitir que o Monerujo
+        escolha o melhor para você!</p>
+        <h2>O que é um Nó?</h2>
+        <p>O Monerujo usa um nó remoto (às vezes também chamado de Daemon) para se comunicar com
+        a Rede Monero sem ter que baixar e armazenar uma cópia do
+        blockchain inteiro.<p>
+        <h2>Lista de Nós</h2>
+        <p>Se a lista estiver vazia, você pode adicionar novos nós manualmente ou deixar que o Monerujo
+        escaneie a rede para você. Ou ambos. Leia mais&#8230;</p>
+        <p>A lista de nós mostra todos os nós conhecidos atualmente. Além disso, a data e hora
+        do último bloco sincronizado para cada nó é exibido abaixo de seu nome. Um ícone
+        representando o comportamento de resposta do nó
+        (o que indica o nível de conectividade esperado)
+        é exibido ao lado.</p>
+        <p>Qualquer nó na lista pode ser favoritado para uso posterior.
+        Os nós que não são marcados como favoritos serão esquecidos.<p>
+        <p>O Monerujo sempre escolherá o nó ideal dentre os marcados.
+        Ele faz isso verificando a altura do bloco (quão sincronizado
+        está o nó?) bem como o comportamento da resposta (com que rapidez o nó responde às solicitações?).</p>
+        <p>A lista é classificada por essas características, portanto, o nó do topo seria o único que o Monerujo
+        escolheria nesse caso. A parte inferior da lista mostraria nós muito lentos ou indisponíveis.</p>
+        <h2>Adicionar um Nó</h2>
+        <p>Ao tocar no botão &quot;Adicionar nó&quot; na parte inferior, você será solicitado a
+        inserir os detalhes do nó no diálogo seguinte.
+        O &quot;Endereço do Host&quot; é o nome do host ou endereço IP do nó - esta é a única
+        informação obrigatória.
+        Digite a &quot;Porta&quot; se o nó for executado em uma porta não padrão (por exemplo, 18089).
+        Você também pode, opcionalmente, dar um nome ao nó para facilitar sua identificação mais tarde.
+        Alguns nós exigem credenciais para serem utilizados. Digite o nome de usuário e
+        senha nos campos apropriados. Agora você pode &quot;testar&quot; essas configurações.
+        Os &quot;Resultados dos Testes&quot; exibirão a altura do bloco, o tempo de resposta e o IP real usado.
+        O resultado também pode ser um erro - geralmente porque o nome do host fornecido
+        não pôde ser alcançado em um período de tempo razoável ou as credenciais estão incorretas.
+        Ou a combinação Nome do Host/Porta não aponta para um Nó Monero válido!
+        Depois que o teste passar (sem erro), você poderá pressionar &quot;OK&quot; para salvar &amp;
+        marcar este nó como favorito.</p>
+        <h2>Escanear Nós</h2>
+        <p>Além disso, você pode verificar a rede em busca de nós. O Monerujo vai começar a
+        escanear a rede por nós remotos na porta 18089. Ele começa perguntando ao seus
+        nós marcados como favoritos por outros pares na rede P2P do Monero e, em seguida, continua
+        perguntando por seus pares, e assim por diante. Se você não tem nós marcados como favoritos
+        (ou eles não nos dizem sobre seus pares),
+        o Monerujo irá direto para os nós codificados direto no Monero em si. O
+        escaneamento termina quando 10 nós remotos são encontrados no total.</p>

     <string name="help_node"><![CDATA[
-        <h1>Nodes</h1>
-        <h2>TL;DR</h2>
-        <p>Refresh the nodes list by pulling down &amp; bookmark 3&#8211;5 nodes to allow Monerujo
-        to choose the best one for you!</p>
-        <h2>What&apos;s a Node?</h2>
-        <p>Monerujo uses a Remote Node (sometimes also called Daemon) to communicate with
-        the Monero Network without having to download and store a copy of the
-        whole blockchain itself.<p>
-        <h2>Node List</h2>
-        <p>If the list is empty, you can either add new nodes manually or let Monerujo
-        scan the network for you. Or both. Read on&#8230;</p>
-        <p>The node list shows all currently known nodes. Additionally, the timestamp
-        of the latest block known to each node is shown under the node name. An icon
-        representing the node&apos;s response behaviour
-        (which indicates the level of connectivity to be expected)
-        is shown next to each node.</p>
-        <p>Any node in the list can be bookmarked for later use.
-        Nodes which are not bookmarked will be forgotten.<p>
-        <p>Monerujo will choose the optimal bookmarked node each time you use it.
-        It does this by checking the blockheight (how up-to-date
-        is the node?) as well as the response behaviour (how fast does the node respond to requests?).</p>
-        <p>The list is sorted by these characteristics, so the top node would be the one Monerujo
-        would choose right now. The bottom of the list would show very slow or unavailable nodes.</p>
-        <h2>Add a Node</h2>
-        <p>By touching the &quot;Add Node&quot; button at the bottom, you will be asked to
-        enter the node details in the following dialog.
-        The &quot;Address&quot; is the hostname or IP-address of the node - this is the only
-        mandatory entry.
-        Enter the &quot;Port&quot; if the node runs on a non-default port (e.g. 18089).
-        You can also optionally name the node, so you can identify it easier later on.
-        Some nodes require credentials to use them. Enter the provided username &amp;
-        password in the appropriate fields. Now you can &quot;Test&quot; these setting.
-        The &quot;Test Results&quot; will display the blockheight, response time and actual IP used.
-        The result may also be an error - usually because the hostname provided is
-        not reachable in a sensible amount of time or the credentials are incorrect.
-        Or the hostname/port combination does not point to an actual Monero Node!
-        Once the test passes (no error) - you&apos;re set to press &quot;OK&quot; to save &amp;
-        bookmark this node.</p>
-        <h2>Scan for Nodes</h2>
-        <p>Additionally, you can scan the network for nodes. Monerujo will start
-        scanning the network for Remote Nodes on port 18089. It begins by asking your
-        bookmarked nodes for other peers in the Monero P2P network and then continues
-        by asking those for their peers, and so on. If you have no bookmarked nodes
-        (or they don&apos;t tell us about their peers),
-        Monerujo will go straight to the Monero seed nodes hardcoded into Monero. The
-        scan stops when it finds 10 remote nodes in total.</p>
+        <h1>節點</h1>
+        <h2>懶人版教學</h2>
+        <p>下拉節點列表即可重新整理節點狀態，你可以手動新增三至五個節點，Monerujo 將會自動為你挑選最佳的節點！</p>
+        <h2>什麼是節點？</h2>
+        <p>Monerujo 必須透過遠端節點 (有時則稱為 Daemon ) 連接至 Monero 交易網路，透過這種方式就不需要下載和儲存整個區塊鏈的副本。<p>
+        <h2>節點列表</h2>
+        <p>如果列表是空白的，你可以自行手動新增節點或是讓 Monerujo 為你掃描網路上的可用節點，以下是詳細教學。</p>
+        <p>節點列表中顯示了目前已知的節點，另外，在名稱下方的的時間戳記表示為其最後更新區塊的時間。
+        每個節點旁邊會有一個圖示來呈現他的狀態 (通常代表著其連接的品質)。</p>
+        <p>每個在列表中的節點都可以加上書籤標記以保留到後續使用，沒有加上書籤的節點則會被捨棄。<p>
+        <p>Monerujo 會在你每次使用錢包時，在書籤內選擇最好的節點。這是透過檢查該節點的區塊高度 (節點資料有多即時？) 與回應狀態 (節點的反應有多迅速？) 來達成。</p>
+        <p>列表會依這些資訊做排序，因此排在最上面的節點就是 Monerujo 目前會使用的節點，列表底部則是反應非常遲鈍或是無法使用的節點。</p>
+        <h2>增加新的節點</h2>
+        <p>點選下方的「新增節點」，你將會被要求輸入節點的資訊。
+        在「位置」這欄請輸入節點的網址或是 IP 位址，這是唯一的必填資訊。
+        如果該節點是運作在非預設的通訊埠 (譬如是 18089)，請輸入於「通訊埠」的欄位中。
+        你也可以命名該節點以方便在後續使用時更容易辨識。
+        若有些節點要求登入資訊，請輸入於「登入名稱」與「密碼」的欄位中。
+        現在你可以按下「測試節點」以檢查節點設定。
+        測試結果將會顯示區塊高度、回應速度與實際的 IP 位址。
+        而測試結果也有可能顯示錯誤，這通常代表著無法在可接受的時間內連接到該節點網址，或是登入資訊設定有誤。
+        也有可能是節點網址與通訊埠的組合有誤而導致無法連接到該 Monero 節點！
+        只要測試結果通過 (沒有錯誤) - 你就可以按下「好的」以儲存該節點並將之加入書籤。</p>
+        <h2>掃描可用的節點</h2>
+        <p>此外，你可以掃描可用的遠端節點，Monerujo 將會掃描網路上開放通訊埠 18089 的遠端節點。
+        首先它會從你的書籤節點先取得 P2P 連接清單，接著再從這些清單內檢查可用的節點。
+        如果你沒有任何書籤節點 (或是書籤節點無法提供它們的連接清單)，Monerujo 將會直接從 Monero 內建的種子節點取得清單。
+        這個掃描功能將會在總共可用節點的數量達到十個後停止。</p>
