+### NavCoin Core Wallet
+
+
+Go to the create proposal page in the Proposal Builder and fill in the form (The proposal builder can be found [here](https://nav-proposal-creator.netlify.com/) )
+
+After filling in the form, click the GENERATE COMMAND button and copy the code that appears below.
+
+Open your NavCoin Core wallet and in the dropdowns select Debug Window under Help.
+
+In the textbox enter `walletpassphrase "passphrase" timeout`, where `"passphrase"` is your wallet’s password and `timeout` is how long you wish to unlock your wallet in seconds.  
+e.g. `walletpassphrase "MySecurePassword" 30`
+
+With your wallet unlocked, paste in the generated code from the proposal website  
+e.g. `createproposal mnyKBfcG4cGfhNZQqbBAaN1ujvjyMEg9wt 1000 42595200 "NavCoin Italia meet up event 2019 funding"`
+
+Your proposal has now been submitted.
+
+
+### NavPi
+
+Open the webview of your NavPi in your web browser  
+e.g. 192.168.30.247
+
+In the top navigation menu click 'Community Fund'
+
+On the community fund page you will see the Create Proposal form. Fill it in and click the GENERATE COMMAND button
+
+Copy the command that it generates and paste it into the `Command` text input below.
+
+Click the Issue Command button.
+
+Your proposal has now been submitted
+
+
+### If something went wrong
+

+title: "Creating swap on NavPi SD card"
+date: "2019-03-21"
+---
+
+These are the consolidated steps from a post by Justin Ellingwood called [Add Swap Space on Ubuntu](https://www.digitalocean.com/community/tutorials/how-to-add-swap-space-on-ubuntu-16-04).
+
+The configuration has been tested on the current version of the NavPi, running Rapsbian GNU/Linux 8 (jessie)
+
+### Prerequisites, Caveats
+For best results, it's recommended to utilize a USB drive as your swap space, due to the fact that repeated reads/writes to the SD card will eventually wear it out. You can follow this [USB swap guide](/stakeboxes/configure-navpi-to-use-usb-swap) or proceed with the SD swap configuration below. For example, you may just want to use the SD swap temporarily until you're ready to move to the USB swap solution.
+
+## Let's get started
+
+### Backup your current NavPi img
+Before proceeding with this swap configuration, it is worth making a backup image of the SD card so if it fails, you can easily restore to this point. 
+
+### Backup your wallet.dat
+To ensure you don't lose any coins while making configuration changes to your NavPi, it's essential to backup the wallet.dat file. This holds your private keys. With a backup of the wallet.dat you can always restore your wallet.
+
+First, make sure your have encrypted your wallet. Then proceed with the following steps:
+
+1. Open the WebUI
+2. Go to `control`
+3. Scroll down to `security`
+4. *Click* `Backup Wallet`. This will download the wallet.dat file to your preferred device (USB, HD)
+5. Save the wallet backup and rename it to `wallet.dat`
+
+### Check system for swap info
+
+    `sudo swapon --show`
+
+### Verify no swap exists
+
+    `free -h`
+
+### Check available space on hard drive
+
+    `df -h`
+
+### Create swap file
+
+    `sudo fallocate -l 2G /navswap`
+
+### Verify correct amount of space reserved
+
+```bash
+    ls -lh /navswap
+
+    Output
+    -rw-r--r-- 1 root root 1.0G Apr 25 11:14 /navswap`
+```
+
+### Make the file only accessible to root
+
+    `sudo chmod 600 /navswap`
+
+### Verify permissions change
+
+```bash
+    ls -lh /navswap
+
+    Output
+    -rw------- 1 root root 2.0G Apr 25 11:14 /navswap
+```
+
+### Mark file as swap space
+
+```bash
+    sudo mkswap /navswap
+
+    Output
+    Setting up swapspace version 1, size = 2048 MiB (1073737728 bytes)
+    no label. UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
+```
+
+### Enable swap file
+
+    `sudo swapon /navswap`
+
+### Verify that the swap is available
+
+```bash
+    sudo swapon --show
+
+    Output
+    NAME      TYPE    SIZE    USED    PRIO
+    /navswap file    2G      0B      -1
+```
+
+### Check the output of the free utility
+
+```bash
+    free -h
+
+    Output
+                  total        used        free      shared  buff/cache   available
+    Mem:           488M         37M         96M        652K        354M        425M
+    Swap:          2.0G          0B        2.0G
+  ```
+
+The swap has been set up successfully. Operating system will begin to use it as necessary.
+
+### Make the Swap File Permanent
+
+First backup your `/etc/fstab` file
+
+   ` sudo cp /etc/fstab /etc/fstab.bak`
+
+Then add the swap info as follows
+```bash
+    echo '/navswap none swap sw 0 0' | sudo tee -a /etc/fstab
+
+    Output
+    /navswap none swap sw 0 0
+```
+
+## Tweak your Swap Settings
+
+Configure your NavPi's performance when dealing with swap.
+
+### Configure swappiness
+
+The swappiness parameter configures how often your system swaps data out of RAM to the swap space. This is a value between 0 and 100 that represents a percentage.
+
+```bash
+    sudo sysctl vm.swappiness=10
+
+    Ouput
+    vm.swappiness = 10
+```
+
+This value is sometimes recommended to improve performance when sufficient memory exists in a system, this value *10* could be considered for the performance being expected.
+
+Make this persist on reboot:
+
+   ` sudo nano /etc/sysctl.conf`
+
+Add this at bottom of file:
+
+ `   vm.swappiness=10`
+
+### Adjust the cache pressure
+
+This setting configures how much the system will choose to cache inode and dentry information over other data.
+
+Check the current cache pressure setting:
+
+```bash
+    cat /proc/sys/vm/vfs_cache_pressure
+
+    Ouput
+    100
+```
+
+By default, the system removes inode information from the cache too quickly.
+
+Set this to a more conservative setting like 50:
+
+```bash
+    sudo sysctl vm.vfs_cache_pressure=50
+
+    Output
+    vm.vfs_cache_pressure = 50
+```
+
+Make it persist:
+
+   ` sudo nano /etc/sysctl.conf`
+
+Add this to bottom of file:
+
+    `vm.vfs_cache_pressure=50`
+
+Save and close the file.
+
+### Reboot NavPi
+
+   ` sudo reboot`
+
+### Verify new swap
+    
+```bash
+    cat /proc/swaps
+
+    Output
+    Filename         Type         Size      Used      Priority
+    /navswap         file         2097418   0         -1
+```
+
+### Check memory usage with swap in place
+
+There are several options for checking memory use.
+
+Built-in commands include:
+
+    `free -h`
+    `top`
+
+**pro tip** - Install htop, a nice option for monitoring interactively. It's a nice way to filter on running processes, like 'nav'. It combines the functionality of top and iotop into a single screen.
+
+```bash
+    sudo apt-get install htop
+    htop
+```
+
+You should now see the swap drive being monitored.
