+Localization information for the o-fish-web project
+
+Localization is in src/helpers/i18n/
+
+Every translation has a directory with its language code, and a translation.json file. e.g.:
+src/helpers/i18n/en/translation.json
+src/helpers/i18n/es-419/translation.json
+src/helpers/i18n/fr/translation.json
+
+When adding a NEW language, you will need to add it in 3 places in src/helpers/i18n/index.js:
+1. Import it, e.g.:
+` import en from './en/translation';`
+` import fr from './fr/translation';`
+
+2. Update the "default to en" to NOT include the new language:
+`if (!(lang.includes('fr') || lang.includes('es'))) {`
+`  lang = 'en';`
+`}`
+ 
+3. You will need to add it into the resources, e.g.:
+`const i18nOptions = {`
+`   resources: {`
+`     en: {`
+`       translation: en`
+`    },`
+`    fr: {`
+`      translation: fr`
+`     }`
+`   }`
+` };`
+
+
+
+The format is a json document where the variable name is in ALL CAPS and in quotes, e.g.:
+`{`
+`  "LOGIN_PAGE": {`
+`    "LOGIN": "Connexion",`
+`    "FORGOT_PASSWORD": "Mot de passe oublié?",`
+`    "EMAIL_USERNAME": "Email/Identifiant:",`
+`    "PASSWORD": "Mot de passe"`
+
